Degenerative disc disease (DDD) is a common spinal condition characterized by the deterioration of intervertebral discs, leading to chronic back pain and reduced mobility. While magnetic resonance imaging (MRI) has long been the standard for late-stage DDD diagnosis, its limitations in early-stage detection prompt the exploration of advanced imaging methods. Positron emission tomography/computed tomography (PET/CT) using ¹⁸F- fluorodeoxyglucose (FDG) and ¹⁸F-sodium fluoride (NaF) has shown promise in identifying metabolic imbalances and age-related spinal degeneration, thereby complementing CT grading of the disease. The novel hybrid imaging modality PET/MRI provides new opportunities and are briefly discussed. The complex pathophysiology of …

Detection Rate And Patterns Of Biochemical Recurrence Of Prostate Cancer Using 18f-Psma-1007 Pet/Ct At A Tertiary Teaching Hospital In Sub-Saharan Africa., Lynet Wairimu Barasa

Master of Medicine in Imaging and Diagnostic Radiology

Background: Rising PSA levels following local therapy with curative intent are seen in about one third of men previously treated for prostate cancer, indicative of disease recurrence. This is usually not detectable through imaging modalities like computed tomography (CT) or magnetic resonance imaging (MRI). Several studies show high detection rates of recurrence with 18F-PSMA-1007 PET/CT, one of the novel PET imaging modalities for prostate cancer. No studies, however, have been done to show the patterns of recurrence in the Sub-Saharan African population in whom prostate cancer is known to occur earlier and be more aggressive. Biochemical recurrence almost always …

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 …

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 …
