Imaging And Non-Imaging Approaches For The Diagnosis And Monitoring Of Necrotizing Enterocolitis-What Lies Ahead?, Indrani Bhattacharjee, Catalina Le Cacheux, Eric B. Ortigoza, Jonathan Dillman, Sherwin S. Chan, Alain Cuna

Manuscripts, Articles, Book Chapters and Other Papers

Necrotizing enterocolitis (NEC) remains one of the most serious gastrointestinal emergencies in preterm infants, and imaging plays a central role in diagnosis and clinical management. Historically, evaluation has relied primarily on abdominal radiography, which remains widely available and embedded in established diagnostic frameworks. However, the hallmark radiographic signs of NEC (i.e., pneumatosis intestinalis, portal venous gas, and free air) reflect relatively advanced manifestations of intestinal injury that indicate established mucosal disruption or transmural necrosis. Bowel ultrasound has increasingly complemented radiography by enabling real-time assessment of bowel wall integrity, perfusion, motility, and intra-abdominal fluid, providing physiologic information that may refine clinical …

Development of a Longitudinal, Small-Group POCUS Curriculum for Internal Medicine Residents

Introduction

Point-of-Care Ultrasound (POCUS) is integral for clinicians to enhance their diagnostic and procedural skills. Unlike Emergency Medicine or Anesthesia training programs, Internal Medicine programs often lack a structured and standardized curriculum. We thus developed a longitudinal and multi-pronged POCUS curriculum aimed at building trainee competency when utilizing ultrasound for diagnostic and procedural work-up.

Methods

The curriculum encompasses the following: basics of ultrasound, ultrasound-guided procedures, thoracic ultrasound/Bed Lung Ultrasound in Emergency (BLUE), and cardiac ultrasound/Focus-Assessed Transthoracic Echocardiography (FATE). These modules were integrated into the residents’ clinic blocks. We utilized …

Perfusion Assessment In Ceus Imaging For Estimating Pancreatic Cancer Response To Sonoporation-Enhanced Chemotherapy., Omri Adler, Priscilla Machado, Trang Vu, Flemming Forsberg, Odd Helge Gilja, Dan Adam

Department of Radiology Faculty Papers

Accurate assessment of perfusion in vital organs like the pancreas is crucial for monitoring various pathologies, particularly tumors and their growth. While tumor growth inhibition usually results in decreased vascularization, current techniques for non-invasive and cost-effective perfusion assessment lack sufficient vessel separability for pancreatic applications, hindering optimal treatment selection and monitoring. Ultrasound (US) imaging offers advantages like low cost, rapid acquisition, non-invasiveness, and non-ionizing radiation. However, speckle, patient-related and acquisition-related motion artifacts, and limitations in distinguishing contrast-enhanced blood vessels, particularly in single frames, pose significant challenges. This study presents a novel solution utilizing image analysis of US contrast agents (UCAs) …

A Comparative Evaluation Of Two Subharmonic-Aided Pressure Estimation (Shape) Analysis Methods, Hailee Mayer, Priscilla Machado, Trang Vu, Annalisa Berzigotti, Jaume Bosch, Elton Dajti, Antonina Antonenko, Kirk Wallace, Flemming Forsberg

Department of Radiology Faculty Papers

Pressure measurement in clinical practice is a valuable tool for diagnostic evaluation, especially in diseases such as portal hypertension. Currently, portal pressures are measured by invasive hepatic vein catheterization, posing risks to patients, and limiting how often measurements can be obtained. Subharmonic-aided pressure estimation (SHAPE) is an ultrasound-based technique that leverages ultrasound contrast agents (UCAs) to estimate changes in hydrostatic pressure. UCAs act as nonlinear oscillators when exposed to high enough acoustic pressures (typically > 200 kPa) and produce significant energy components ranging from subharmonics to higher harmonics. Tissues do not generate significant subharmonic components, thus making it the optimal component …

Efficacy Of Neuromuscular Ultrasound In Diagnosing And Treating A Mammogram-Induced Brachial Plexus Injury-A Case Report, Jaime Dougherty, Tyler Pigott, Altamash E Raja

Rowan-Virtua School of Osteopathic Medicine Departmental Research

A 40-year-old woman presented with chronic left anterior shoulder, upper arm, and axillary pain following a routine mammogram 3 years prior. Despite multiple interventions, her pain persisted significantly affecting her quality of life. Ultrasound examination revealed fascicular edema in the medial brachial cutaneous nerve (MBCN), intercostobrachial cutaneous nerve (ICBN), and a positive sono-Tinel. Ultrasound-guided hydrodissection of these nerves provided complete axillary pain relief and significant improvement in anterior arm pain, sustained for 6 months. This case highlights the diagnostic challenges of cutaneous nerve entrapment syndromes, often overlooked and misdiagnosed, especially without a clear inciting injury. Ultrasound proves superior to electrodiagnostic …

Ultrasonographic Appearance Of Suspected Zinner Syndrome, Wen Hao Luo, Jared Garfinkle, Jack Hennen, Robert Martin, Kathleen Deiling

Rowan-Virtua Research Day

Zinner syndrome (ZS) is a rare congenital condition characterized by the triad of unilateral renal agenesis, ipsilateral seminal vesicle cyst, and ipsilateral ejaculatory duct obstruction. ZS is suspected to be caused by the malformation of the mesonephric duct during embryogenesis. The incomplete migration of the ureteric bud results in ipsilateral renal agenesis and ejaculatory duct obstruction. The remaining gonad develops with inadequate seminal fluid drainage, leading to the formation of seminal vesicle cysts. ZS is often asymptomatic, leading to challenges in diagnosis, particularly in adolescents. Symptoms can include pain, dysuria, pollakisuria, perineal pain, epididymitis, and pain after ejaculation. Imaging plays …

Faculty, Staff and Students Publications

BACKGROUND: Professional guidelines recommend HCC screening in at-risk patients using semi-annual ultrasound with or without alpha-fetoprotein (AFP); however, this strategy has limited effectiveness due to low adherence and sensitivity. Increasing data support the potential role of blood-based biomarker panels, which could improve both aspects. The biomarker panel GALAD, comprised of sex, age, and 3 blood biomarkers (AFP, AFP-L3, and des-carboxy prothrombin des-carboxy prothrombin), has shown high sensitivity and specificity in biomarker phase II (case-control) and phase III (retrospective cohort) validation studies. However, prospective validation in a large phase IV biomarker clinical utility trial is necessary before its adoption in practice. …

Department of Radiology Faculty Papers

Objectives: The incidence of chronic liver diseases in children is increasing worldwide due to congenital, metabolic, autoimmune and viral diseases. Currently, liver biopsy for fibrosis assessment is considered the gold standard. However, this procedure is invasive, may result in unavoidable complications and is prone to sampling errors. These limitations have led to an increasing demand for noninvasive methods for fibrosis screening. Artificial intelligence integration in ultrasound diagnosis of liver fibrosis has gained interest in clinical research. In the current study we used a cloud-based artificial intelligence platform utilizing transfer learning to evaluate the accuracy of B-mode ultrasound based AI model …

Assessing The Concomitant Presentation Of Acl And Anterolateral Ligament Injuries, Kiang Huang, Katherine Quesada-Tibbetts, Leela Prakash, Neelesh Prakash

Radiology Student Publications

Anterior cruciate ligament (ACL) injuries severely compromise the quality of life in affected patients, so early detection of concurrent injuries is crucial for quicker rehabilitation and proper surgical treatment. Although injuries to the medial meniscus and medial collateral ligament are frequently linked to damage to the ACL, little is known about other important but underappreciated ligament lesions in individuals with ACL injury. The anterolateral ligament (ALL) is a less well-known lesion that presents tearing injuries in 32%-88% of patients with ACL tears in the same knee, with a higher prevalence in complete ACL tears. Despite their lower occurrence, ALL tears …

Commonly Missed Miscellaneous Ligament Injuries Co-Occurring With Acl Tears On Diagnostic Imaging, Katherine Quesada-Tibbetts, Kian Huang, Mafaz Kattih, Albert Brotgandel, Neelesh Prakash

Radiology Student Publications

Anterior cruciate ligament (ACL) injuries greatly affect patient quality of life, necessitating the early identification of additional injuries for faster recovery and appropriate surgical care. Although injuries to the medial meniscus and medial collateral ligament are commonly linked with ACL injuries, there is less awareness of other significant but less recognized ligament lesions in ACL-deficient patients. These less-common injuries include meniscal ramp lesions and meniscal root tears. Research indicates that concomitant ramp lesions are present in 15%-42% of ACL reconstructions, lateral meniscal root tears in 10%-14%, and medial meniscal root tears in a mere 3%. Despite their lower incidence, meniscal …

Ultrasound Versus Radiography For Evaluating Surgical Necrotizing Enterocolitis, Sayed H. Aftab, Santiago Martinez-Correa, Minh-Huy Huynh, Wondwossen T. Lerebo, Jorge Delgado, Rebecca Denis, Misun Hwang

Rowan-Virtua Research Day

Purpose:

Necrotizing enterocolitis (NEC) is an abdominal inflammatory condition that is common in premature neonates. Although abdominal radiograph (AR) remains the imaging standard for NEC, it may miss up to 50% of early signs of NEC and has been described to have a sensitivity as low as 15.4% for detecting pneumoperitoneum. Abdominal ultrasound (US) is portable, non-invasive, and allows real-time bowel integrity, movement, and perfusion assessment. We aim to evaluate the concordance between US and AR in detecting NEC features and the diagnostic performance of both modalities in detecting pneumoperitoneum.

Methods and materials:

We conducted an IRB-approved retrospective, cross-sectional, single-center …

Evaluating Bone Fracture Healing Utilizing Novel Ultrasound Modes, X-Ray And Dual-Energy X-Ray Absorptiometry In A Rabbit Model, Priscilla Machado, Rachel Blackman, Ji-Bin Liu, Flemming Forsberg, Traci Fox

Department of Radiology Posters

Background and Purpose

Healing in bone fractures is a complex process involving local inflammation, angiogenesis (i.e., the creation of new blood vessels), and formation of a bone-building callus, all of which leads to returning the bone nearly to its pre-fracture state. This is the process in a bone where the fracture is clean and the fractured ends oppose each other. Five to 10 percent of fractures are described as non-union, which can lead to poor healing and long-term complications. The purpose of this study was to compare fracture healing in a rabbit model using x-ray, the traditional method for evaluating …

Manuscripts, Articles, Book Chapters and Other Papers

Diagnosis of necrotizing enterocolitis (NEC) relies heavily on imaging, but uncertainty in the language used in imaging reports can result in ambiguity, miscommunication, and potential diagnostic errors. To determine the degree of uncertainty in reporting imaging findings for NEC, we conducted a secondary analysis of the data from a previously completed pilot diagnostic randomized controlled trial (2019-2020). The study population comprised sixteen preterm infants with suspected NEC randomized to abdominal radiographs (AXRs) or AXR + bowel ultrasound (BUS). The level of uncertainty was determined using a four-point Likert scale. Overall, we reviewed radiology reports of 113 AXR and 24 BUS …

A Rare Appendiceal Mucocele Of The Appendix Captured On The Ultrasound: Case Report, Vera Shulgina, Meghan Single, Joel Thompson

Advances in Clinical Medical Research and Healthcare Delivery

Appendiceal mucocele is a rare disease which results from an accumulation of mucus in the lumen of the appendix, leading to distension and obstruction of the lumen. Clinical diagnosis is often delayed, as the presenting symptoms are usually non-specific. Even with the use of imaging, preoperative diagnosis is difficult. The treatment is surgical, with the extent determined by the surgical specimen. Definitive diagnosis is by histopathology. Our case report presents a rare case of appendiceal mucocele originally captured by ultrasound. The aim of this paper is to further understand the clinical presentation, discuss key ultrasound findings, and examine the proper …

Automated Lung Ultrasound Pulmonary Disease Quantification Using An Unsupervised Machine Learning Technique For Covid-19, Hersh Sagreiya, Michael A Jacobs, Alireza Akhbardeh

Faculty, Staff and Student Publications

COVID-19 is an ongoing global health pandemic. Although COVID-19 can be diagnosed with various tests such as PCR, these tests do not establish pulmonary disease burden. Whereas point-of-care lung ultrasound (POCUS) can directly assess the severity of characteristic pulmonary findings of COVID-19, the advantage of using US is that it is inexpensive, portable, and widely available for use in many clinical settings. For automated assessment of pulmonary findings, we have developed an unsupervised learning technique termed the calculated lung ultrasound (CLU) index. The CLU can quantify various types of lung findings, such as A or B lines, consolidations, and pleural …

Making Waves: How Ultrasound-Targeted Drug Delivery Is Changing Pharmaceutical Approaches., Lauren J Delaney, Selin Isguven, John R Eisenbrey, Noreen J Hickok, Flemming Forsberg

Department of Radiology Faculty Papers

Administration of drugs through oral and intravenous routes is a mainstay of modern medicine, but this approach suffers from limitations associated with off-target side effects and narrow therapeutic windows. It is often apparent that a controlled delivery of drugs, either localized to a specific site or during a specific time, can increase efficacy and bypass problems with systemic toxicity and insufficient local availability. To overcome some of these issues, local delivery systems have been devised, but most are still restricted in terms of elution kinetics, duration, and temporal control. Ultrasound-targeted drug delivery offers a powerful approach to increase delivery, therapeutic …

Avoidable And Unavoidable Repeat Breast Core Needle Biopsies, Xiaoqin Wang, Fara Shikoh, Mauro Hanaoka, Aurela Clark

Radiology Faculty Publications

Background: Breast core needle biopsies are not perfect and could miss cancer. The need for a repeat breast core biopsy is not uncommon and can occur for a multitude of reasons. Radiologists should carefully correlate the pathology results with imaging features after each breast biopsy and must recognize why certain core biopsies must be repeated to avoid missed or delayed cancer diagnosis. In this review, we discuss the main reasons for repeat core biopsies via case presentation with radiological images and pathological correlation. This review will help multidisciplinary breast care team recognize when to repeat a biopsy to reduce false …

Bilateral Popliteal Entrapment Syndrome In A Young Athlete Diagnosed With Ultrasound, Hanna K. Thompson, Justin R. Montgomery, Paul J. Spicer

Radiology Faculty Publications

Popliteal artery entrapment syndrome (PAES) occurs when the popliteal artery is compressed by abnormally developed or hypertrophied muscles adjacent to the popliteal fossa. When symptomatic, it most frequently presents with leg cramping while walking or running. We describe the case of an 18-year-old female runner presenting with claudication and exercise intolerance. After MRI was non-diagnostic, diagnostic ultrasound demonstrated that she had functional (Type VI) PAES. She subsequently underwent popliteal artery release surgery. Type VI PAES should be considered in young, healthy patients who present with claudication, particularly athletes.
