Fractional Flow Reserve From Coronary Ct: Evidence, Applications, And Future Directions, Arta Kasaeian, Mohadese Ahmadzade, Taylor Hoffman, Mohammad Ghasemi-Rad, Anoop Padoor Ayyappan

Faculty, Staff and Students Publications

Coronary computed tomography angiography (CCTA) has emerged as the leading noninvasive imaging modality for the assessment of coronary artery disease (CAD), offering high-resolution visualization of the coronary anatomy and plaque characterization. The development of fractional flow reserve derived from CCTA (FFR-CT) has further transformed the diagnostic landscape by enabling the simultaneous evaluation of both anatomical stenosis and lesion-specific ischemia. FFR-CT has demonstrated diagnostic accuracy comparable to invasive FFR. The combined use of CCTA and FFR-CT is now pivotal in a broad range of clinical scenarios, including the evaluation of stable and acute chest pain, assessment of high-risk and complex plaque …

Utility Of Ebus-Tbna In Evaluating Mediastinal And Hilar Lymphadenopathy In Patients With Silica Exposure: A Retrospective Single-Center Study, Tarake M. Aljarod, Atul C. Mehta, Saroj Sigdel, Mark Jason Akers, John L. Saylor, Caleb S. Clark, Yousef Shweihat

Pulmonology

Background: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is used effectively in staging lung cancer and in the evaluation of benign causes of mediastinal and/or hilar lymphadenopathy (MHL), such as sarcoidosis. However, evidence for its utility in the diagnostic workup of silicosis is limited.

Methods: This single-center retrospective study included patients with occupational silica exposure who underwent EBUS-TBNA to evaluate MHL on computed tomography (CT). Cytology specimens were re-examined by an independent pathologist under polarized microscopy, and cytologic criteria for the diagnosis of LN silicosis were formulated from the findings. Primary outcomes were the determination of the diagnostic yield (DY) of …

Department of Radiology Faculty Papers

Vascular endothelial growth factor receptors (VEGFRs) are key regulators of angiogenesis, lymphangiogenesis, and vascular permeability, playing essential roles in both physiological and pathological processes. The VEGFR family, including VEGFR-1, VEGFR-2, and VEGFR-3, interacts with structurally related VEGF ligands (VEGFA, VEGFB, VEGFC, VEGFD, and placental growth factor [PlGF]), activating downstream signaling pathways that mediate critical cellular processes, including proliferation, migration, and survival. Dysregulation of VEGFR signaling has been implicated in numerous diseases, such as cancer, cardiovascular conditions, and inflammatory disorders. Targeting VEGFRs with radiopharmaceuticals, such as radiolabeled peptides, antibodies, and specific tracers like 64Cu-bevacizumab and 89Zr-ramucirumab, has emerged as a powerful …

Department of Medicine Faculty Papers

Musculoskeletal tumors present a diagnostic challenge due to their rarity, histological diversity, and overlapping imaging features. Accurate characterization is essential for effective treatment planning and prognosis, yet current diagnostic workflows rely heavily on invasive biopsy and subjective radiologic interpretation. This review explores the evolving role of radiogenomics and machine learning in improving diagnostic accuracy for bone and soft tissue tumors. We examine integrating quantitative imaging features from MRI, CT, and PET with genomic and transcriptomic data to enable non-invasive tumor profiling. AI-powered platforms employing convolutional neural networks (CNNs) and radiomic texture analysis show promising results in tumor grading, subtype differentiation …

How Far Does It Go? An Analysis On The Extent Of Spinal Cord Injury In Post-Traumatic Patients, Sravani Mannuru, Sarvani Uppati, Kelsey Baker

Research Colloquium

Background: Spinal cord injury causes debilitating functional loss in post-trauma patients. Previous studies have showed that an area of edema (tissue damage and swelling) occurs at the level of spinal damage and may be related to the amount of functional loss in the patient and their associated recovery potential. We hypothesized that the extent of the injury is greater than previously studied and may better explain functional loss and recovery potential.

Methods: We retrospectively analyzed five T2-weighted MRI spinal cord images from post-trauma patients ages 32-67. Patients had a clinically diagnosed spinal cord injury that affected the cervical …

Imaging Hallmarks Of Idiopathic Intracranial Hypertension And Insights Into Pathogenesis, Albalooshy Basimah, Scott Faro, Hsiangkuo Yuan, Kiran Talekar, Prabath Mondel, Enchao Qiu, Joga Chaganti

Department of Radiology Faculty Papers

Idiopathic Intracranial hypertension (IIH), also referred to as pseudotumor cerebri, is a term used to describe increased intracranial pressure in the absence of a known identifiable secondary cause. Despite advancements of neuroimaging techniques, imaging of the pathological underpinnings in the diagnosis of IIH has been limited. Although the causation of IIH has been ascribed to increased Cerebrospinal Fluid production and disordered drainage through the dural sinuses, new evidence shows that the glymphatic system which is an alternate pathway of drainage is likely to play a pivotal role. In this review, we address the pathophysiological underpinnings in the causation of IIH …

Publications and Research

Characterizing imaging performance requires a multidisciplinary approach that evaluates various interconnected parameters, including dosage optimization and dynamic accuracy. Radiation dose and dynamic accuracy are challenged by patient motion that results in poor image quality. These challenges are more prevalent in the brain/cardiac pediatric patient imaging, as they relate to excess radiation dose that may be associated with various complications. Scanning vulnerable pediatric patients ought to eliminate anesthesia due to critical risks associated in some cases with intracranial hemorrhages, brain strokes, and congenital heart disease. Some pediatric imaging, however, requires prolonged scanning under anesthesia. It can often be a laborious, suboptimal …

Can Anemia Be A Prognostic Indicator To Scope For Gastroesophageal Junction Adenocarcinoma?, Ryan Tam, Neha Narayanan, Evan Basha, Joel Thompson

Advances in Clinical Medical Research and Healthcare Delivery

Gastroesophageal junction adenocarcinoma is a rapidly progressive disease that has a poor prognosis with a 5-year survival rate of 20%. It commonly presents with major symptoms of dysphagia and weight loss in addition to a long-standing history of reflux. As of now, screening for esophageal adenocarcinoma (EAC) is dependent on identifying risk factors which include a family history of Barrett’s esophagus and esophageal adenocarcinoma or patients with gastroesophageal reflux disease and at least one other risk factory for EAC such as age greater than 50 years, obesity or central adiposity, history of smoking, or male gender. Here, we present a …

This case describes a 27-year-old male from Mali with no significant medical history presenting with progressive fatigue, shortness of breath, and palpitations over one year. Family history revealed sudden cardiac death in his father in his 30s. Physical examination and initial investigations, including echocardiography, …

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 …

Predicting Coronary Artery Calcium Using Abdominal Aorta And Visceral Artery Calcification, Jared Dixon, Sayf Al-Katib, Kiran Nandalur, Jacob Ghannam, Ali Beydoun, Desiree Clement

Posters

CAC scoring has emerged as a widely available, consistent, and reproducible means of assessing risk for major cardiovascular outcomes, especially useful in asymptomatic people for planning primary prevention interventions such as statins and aspirin.1 The Multiethnic Study of Atherosclerosis (MESA) demonstrated that a CAC score of 0 represents a less than 5 percent 10-year Atherosclerotic cardiovascular disease (ASCVD) risk. CAC scores 1-299 represent borderline to intermediate risk, and CAC score >300 represents a “high risk” 10 percent or greater 10-year ASCVD risk.2

When used correctly, CAC scoring is a powerful predictor of ASCVD risk and holds the key for many …

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 …

The Importance Of How And When In Measuring Epicardial Adipose Tissue, Brian Fardman, Juan Antonio Requena-Ibáñez, Carlos García Santos-Gallego, Anderly José Rodriguez Cordero, Samantha Sartori, Javier Sanz Sanz, Valentin Fuster, Juan José Badimon

Rowan-Virtua Research Day

Epicardial Adipose Tissue (EAT) is drawing increasing attention. As a quantifiable, modifiable, and potentially new cardiovascular therapeutic target, its accurate measurement is particularly relevant. In Cardiac Magnetic Resonance (CMR) different methods can be used to assess EAT burden. We take advantage of CMR-studies of EMPATROPISM trial to assess EAT through three different methods, evaluate the effect of Empagliflozin and look for significant difference in the ability to detect changes in serial measurements. In some settings such as treatment-induced changes or patient follow-up, multi-slice method of EAT evaluation provides higher accuracy to detect significant differences, otherwise unnoticed by single-slice approaches.
