Radiation Dose In Computed Tomography (Ct), Helen Minnick

Medical Imaging Senior Posters

Computed Tomography (CT) is a critical diagnostic tool that delivers rapid, detailed cross-sectional imaging but remains a major contributor to medical radiation exposure. Increasing use of CT has led to concerns about excessive or low-value exams, including repeat scans that do not often change patient management and may increase long-term cancer risk. Evidence shows that only a small percentage of repeat head CTs reveal clinically significant findings, underscoring the importance of justification and reducing unnecessary imaging. Pediatric patients are particularly vulnerable due to increased tissue radiosensitivity and longer lifespans, making dose optimization essential. National initiatives such as Image Gently and …

Magnetic Resonance Imaging Safety And Considerations, Lauren Mosier

Medical Imaging Senior Posters

Abstract

Magnetic Resonance Imaging (MRI) is considered to be a safe, non-invasive diagnostic modality. However, the presence of a strong magnetic field creates inherent risks when safety protocols are not followed. This project examines MRI safety, with particular focus on the recent fatality in New York, where a person was killed by a projectile accident in the scanner room. Such events highlight the catastrophic consequences that can result from lapses in screening procedures, inadequate staff training, or poor enforcement of zone protocols. By reviewing this incident in the context of MRI safety protocols, this project emphasizes the ongoing need for …

A Hidden Source Of Ostomy Bleeding: Meckel Diverticulum, Shiva Morisetty, Ezekiel Kapusiak, Kumar Shah

East Florida Division GME Research Day 2025

Adult Meckel diverticulum can present atypically compared to classic childhood Meckel diverticulum. Given the increased likelihood of concurrent medical conditions in adults, it is often overlooked in the differential for lower gastrointestinal bleeding. We report a 61-year-old male with rectal adenocarcinoma status post low anterior resection and diverting loop ileostomy who presented repeatedly with hematochezia via the ostomy. Prior episodes were managed conservatively. During the index admission, esophagogastroduodenoscopy and ileoscopy did not identify a bleeding source; a clip was placed near the suspected site. Interventional radiology was consulted for mesenteric angiography. Superior mesenteric angiography demonstrated a tortuous aberrant ileal branch …

Fatal Overlapping Cns Infections: Radiologic Correlates Of Ventriculitis, Encephalitis, And Meningitis​, Jesse F. Simon, Sara Darwish, Stephanie Nagy, Richard Shalmiyev, David Kosoy, Bryan Rubio, Gustavo Pantol, Mauricio Danckers

East Florida Division GME Research Day 2025

Introduction: This case study explores an uncommon triad of encephalitis, ventriculitis, and meningitis complicated by ischemic strokes and seizures in a COVID-19-positive patient. Prior studies suggest that bacterial meningitis and encephalitis can lead to cerebral infarctions due to inflammation and vascular injury.1,2,5 Ventriculitis, in particular, is rarely observed and typically is seen as a severe complication of meningitis, and can be managed with neurosurgical interventions such as CSF shunt placement, ventricular drains, or other intracranial devices.3,4 The simultaneous presentation of all three conditions in a single patient is rare and poses significant challenges from a diagnostic and management standpoint.

Tryptophan Kynurenine Pathway-Based Imaging Agents For Brain Disorders And Oncology-From Bench To Bedside, Erik Stauff, Wenqi Xu, Heidi H. Kecskemethy, Sigrid A. Langhans, Vinay V. R. Kandula, Lauren W. Averill, Xuyi Yue

Jefferson Hospital Staff Papers and Presentations

Tryptophan (Trp)-based radiotracers have excellent potential for imaging many different types of brain pathology because of their involvement with both the serotonergic and kynurenine (KYN) pathways. However, radiotracers specific to the kynurenine metabolism pathway are limited. In addition, historically Trp-based radiopharmaceuticals were synthesized with the short-lived isotope carbon-11. A newer generation of Trp-based imaging agents using the longer half-lived and commercially available isotopes, such as fluorine-18 and iodine-124, are being developed. The newly developed amino acid-based tracers have been demonstrated to have favorable radiochemical and imaging characteristics in pre-clinical studies. However, many barriers still exist in the clinical translation of …

Comparing The Patient Shielding Practices For Healthcare Facilities In Southeast Georgia, Genesis Horton

Honors College Theses

Since the discovery of X-rays in 1895, research has consistently been conducted on their capabilities and limitations in healthcare. One primary focus of interest is patient shielding, especially regarding radiation protection and patient safety. Introduced in the mid-1900s, patient shielding has been practiced to protect the gonads, the thyroid, and other radiosensitive body parts. This research project investigated common shielding protocols implemented in healthcare facilities, specifically within Southeast Georgia. This study utilized anonymized in-person interviews with local imaging departments regarding their procedures and protocols for patient shielding. Results from these interviews have been analyzed and compared to shielding best practices …

Ultrasound-Guided Percutaneous Needle Barbotage And Ultrasonic Tenotomy For Rotator Cuff Calcific Tendinopathy, Toru Omodani

Rehabilitation Practice and Science

Rotator cuff calcific tendinopathy (RCCT) is a common source of shoulder pain caused by calcium deposits within the rotator cuff tendons. Ultrasound-guided interventions have emerged as effective, minimally invasive alternatives to surgery for symptomatic cases unresponsive to conservative treatments. This review summarizes two primary techniques: percutaneous needle barbotage and percutaneous ultrasonic tenotomy. In needle barbotage, one or two needles are inserted under ultrasound guidance to inject and aspirate saline, thereby fragmenting and removing the calcific deposit. This method yields rapid pain relief and improved shoulder function, with follow-up imaging often demonstrating near-complete deposit resolution. For particularly hard or recalcitrant deposits, …

Balancing Regeneration And Resistance: Targeting Dclk1 To Mitigate Gastrointestinal Radiation Injury And Oncogenesis, Landon L. Moore, Jerry Jaboin, Milton L. Brown, Courtney W. Houchen

Department of Medicine Faculty Publications

Ionizing radiation (IR) poses a dual challenge in medicine; while essential for cancer therapy, it inflicts collateral damage to normal tissues, particularly the gastrointestinal (GI) tract. High-dose IR triggers acute radiation syndrome (ARS), characterized by crypt stem cell depletion, mucosal barrier disruption, inflammation, and potential progression to fibrosis and secondary malignancy. Emerging evidence identifies the epithelial kinase doublecortin-like kinase 1 (DCLK1)—highly expressed in GI tuft cells and cancer stem-like cells—as a master regulator of post-IR responses. DCLK1 integrates DNA repair (via p53/ATM), and survival signaling (via NF-κB, TGF-β, and MAPK) to promote epithelial regeneration, yet these same mechanisms contribute to …

Sarcoidosis With Isolated Osseous Manifestations Mimicking Metastatic Malignancy, Ahmed Ismail, Ahmed Saleh, Yanis Boumber

Department of Medicine Faculty Publications

Sarcoidosis is an inflammatory disease of unknown etiology that commonly involves multiple organ systems, with the lungs and lymph nodes most frequently affected. Osseous involvement, although recognized, is considered uncommon and often overlooked due to its nonspecific clinical and radiographic features. Patients may be asymptomatic or present with pain, swelling, and functional limitations of the affected limb. Imaging can reveal findings such as bone lesions that mimic malignancy, including lytic or sclerotic changes. Diagnosis relies on histopathological confirmation of non-caseating granulomas. Treatment is directed at symptom relief and preservation of limb function. Here, we present a rare case of isolated …

Multidisciplinary Emergent Control Of Traumatic Neovaginal Bleeding After Foreign-Body Insertion In The Early Postoperative Period After Gender-Affirming Vaginoplasty., Tanisha S Kashikar, Christopher D Mcclung, Michal A Radomski, Anand K Joshi, David C Evans

Trauma and Acute Care Articles

As gender-affirming surgery becomes more widespread, it is important that healthcare providers recognize complications related to gender-affirming surgery. Although rates of postoperative bleeding after gender-affirming vaginoplasty are relatively low, it is imperative that this potentially life-threatening complication is recognized and managed quickly. This case highlights the importance of a multidisciplinary approach to the management of neovaginal bleeding that was unable to be controlled intraoperatively by suture ligation.

Percutaneous Stenting As Treatment For Chylothorax From Superior Vena Cava Syndrome: A Case Report, Arta Kasaeian, Taylor Hoffman, Mohammad Ghasemi Rad, David Wynne, David Léon

Faculty, Staff and Students Publications

Superior vena cava syndrome is a condition that results from obstruction of the superior vena cava, the etiology of which can be benign or malignant. The impaired venous return can cause facial and upper extremity swelling, dyspnea, and neurologic symptoms. Chylothorax is a rare complication of superior vena cava syndrome. We report a case of a 69-year-old male with end-stage renal disease, who developed both a chylothorax and a contralateral simple pleural effusion secondary to superior vena cava syndrome. He was successfully treated with percutaneous endovascular stenting.

Background and purpose: A high-quality treatment planning process is crucial in advanced radiotherapy techniques to ensure adequate dose to the target volume (TV) and sparing of organs at risk (OARs). This process often requires intensive labor, creating barriers for deployment in low- and middle-income countries (LMICs). We aimed to establish the feasibility of implementing knowledge-based auto-planning to facilitate clinical efficiency and increase patient throughput in an LMIC.

Materials and methods: We evaluated 60 randomly selected VMAT manual plans (VMPs), including 10 for each of the following sites: head and neck, oesophagus, breast, prostate, cervical, and rectal cancers. Using the same …

Automated Segmentation Of The Ulnar Nerve In Mri Using Deep Learning Techniques, Akhil Nagulapalli

Theses

Cubital Tunnel Syndrome (CuTS), a condition caused by compression of the ulnar nerve, results in numbness, tingling, pain, and even muscle atrophy, affecting fine motor skills and diminishing patient quality of life. Accurate diagnosis of CuTS is challenging, as current diagnostic methods—including clinical exams, nerve conduction studies, and unaided MRI—often lack the precision to reliably identify the nerve and detect compression in its early stages. Deep learning-based segmentation offers a promising solution, enabling precise and automated identification of nerve structures in MRI images, which could significantly improve diagnostic accuracy and support timely intervention.

A novel deep learning model for segmenting …

Manipal Journal of Medical Sciences

We report an unusual case of an 8-month-old child, who presented to us with a mass per abdomen with confusing imaging characteristics reported as a germ cell tumour / Neuroblastoma.

Patient presented with a large mass per abdomen which had both retroperitoneal and intraperitoneal components and was compressing the adjacent structures and was appearing heterogenous with calcifications within. The more favoured diagnosis on imaging was a peritoneal or retroperitoneal germ cell tumor / Neuroblastoma. Repeated imaging revealed that the mass was abutting / compressing the left lobe of the liver and high AFP beta HCG and LDH values were noted. …

Navigating Rarity: A Case Report On Primary Splenic Lymphoma, Santosh Pv Rai, Skand Rastogi, Anshuman Senapati, Jyoti Kini, Salama Yasmeen

Manipal Journal of Medical Sciences

Primary Splenic Lymphoma (PSL) is a rare condition, which complicates its understanding and definition. The rarity of PSL has led to varied definitions: some consider it primary only if splenomegaly is predominant, while others include spleen involvement with hilar lymph nodes. Documentation on PSL is sparse in Indian literature. This case report of a 48-year-old woman, presenting with fever, weight loss, and left hypochondrium pain, and diagnosed with PSL through CECT abdomen and USG-guided biopsy, contributes to better understanding of the condition.
