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 …

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 …

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 …

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.

Introduction: PET/CT has a synergistic value for optimal diagnosis, disease activity monitoring, and evaluation of damage progression in large vessel vasculitis. The use of standardized uptake values (SUV) as a measurement of relative tissue uptake facilitates comparisons between patients, and has been suggested as a basis for diagnosis. The SUVmean and SUVmax reproducibility in vascular structures is not widely studied.

Objective: The objective of this study was to evaluate the inter-observer variability of both qualitative visual grading of aortic 18F-FDG uptake and the quantitative aortic mean and maximum SUVs in these patients with mild to moderate covid-19 infection …

Ultrasound-Guided Vs. Fluoroscopy Guided Steroid Injection For Lumbar Spine Pain On Functional And Pain Outcomes: A Systematic Review, Yashas Sattur, Akash Patel, Alec Birnbaum, Athena Nomula

Rowan-Virtua Research Day

Fluoroscopy-guided steroid injections are standard for lumbar spine pain but involve radiation. Ultrasound offers a safer, radiation-free alternative. Ultrasound-guided injections are non-inferior in improving pain and function. A systematic review of PubMed, Embase, Cochrane, Scopus, and Web of Science was conducted. Studies in adults comparing ultrasound and fluoroscopy-guided injections reporting VAS, NRS, or ODI were included. Fifteen studies showed both techniques significantly improved pain and function, with no consistent superiority. Ultrasound-guided injections are effective and safe, providing comparable outcomes to fluoroscopy while eliminating radiation exposure.

Prostatic Urethral Length On Mri As A Predictor Of Late Genitourinary Toxicity After Prostate Cancer Radiation, Kyu Kim, Joseph Lee, Allison Hazy, Sayf Al-Katib, Hong Ye, Nathan Kolderman, Abhay Dhaliwal, Daniel Krauss, Thomas Quinn, Kimberly Marvin, Kiran R. Nandalur

Posters

Radiation therapy (RT) is a widely used treatment for prostate cancer.1 While effective, some patients develop late genitourinary (GU) toxicity, which can impact quality of life.2,4 Identifying pre-treatment factors that predict toxicity risk may help improve clinical decision-making. Recent studies suggest that prostatic urethral length (PUL) seen on MRI is associated with an increased risk of late GU toxicity.3 Understanding this relationship could enhance risk stratification before treatment.

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 …

Faculty, Staff and Student Publications

Percutaneous image-guided thermal ablation is an established local curative-intent treatment technique for the treatment of primary and secondary malignant liver tumors. Whereas margin assessment after surgical resection can be accomplished with microscopic examination of the resected specimen, margin assessment after percutaneous thermal ablation relies on cross-sectional imaging. The critical measure of technical success is the minimal ablative margin (MAM), defined as the minimum distance between the tumor and the edge of the ablation zone. Traditionally, the MAM has been assessed qualitatively using anatomic landmarks, which has suboptimal accuracy and reproducibility and is prone to operator bias. Consequently, specialized software-based methods …

The Development Of A Trauma Interventional Radiology Alert Protocol Reduces Time To Vessel Puncture In Cases Of Active Hemorrhage., Aahad Khan, Akhil Gangisetty, Steve Mitchell, Nick Daughtery, Brent Goslin, William B Devoe, John Bach

Trauma and Acute Care Articles

Introduction Trauma continues to be a major cause of death in the United States, with uncontrolled bleeding contributing to a significant portion of trauma-related fatalities. In recent years, the management of hemorrhagic trauma patients has expanded to include interventional radiology (IR). The American College of Surgeons Committee on Trauma recommends that Level 1 and 2 trauma centers ensure IR availability within 60 minutes of the decision to proceed with angiography. Delays in IR intervention are associated with poorer outcomes and increased mortality. To address this, our Level 2 trauma center developed and implemented an institutional protocol involving trauma surgeons, interventional …

Background: Approximately 20% of all transient ischaemic attacks (TIAs) and ischaemic strokes occur within the posterior circulation, with vertebrobasilar stenosis identified as the cause in roughly 25% of the cases. Studies have shown that about a quarter of these patients have atherosclerotic stenosis of at least 50% of the vertebrobasilar artery. Stenosis has been shown to be associated with an increased risk of 90-day recurrent vertebrobasilar stroke, particularly in the first few weeks, which is significantly higher when compared with patients with stenosis of the anterior circulation. Therefore, aggressive treatment is important for the patient's prognosis. Stenting is emerging as …
