Sonographic Evaluation Of An Urachal Remnant: A Case Report, Courtney Gushi Mar 2025

Sonographic Evaluation Of An Urachal Remnant: A Case Report, Courtney Gushi

SACAD: Scholarly Activities

Urachal anomalies are rare and often identified incidentally during diagnostic imaging studies, such as sonography. These anomalies are being detected with increasing frequency due to advancements in cross-sectional medical imaging. Sonography is a key diagnostic modality due to its lack of radiation, cost-effectiveness, and widespread ability. Urachal anomalies have the potential to undergo pathological changes, leading to inflammation, infection, and even malignancy. Therefore, it is imperative for sonographers to be proficient in identifying and understanding sonographic characteristics of urachal abnormalities.

Asymmetrical Glymphatic Dysfunction In Patients With Long Covid Associated Neurocognitive Impairment- Correlation With Bbb Disruption, Joga Chaganti, Tanush Talekar, Bruce J. Brew

Department of Radiology Faculty Papers

BACKGROUND AND PURPOSE: The glymphatic system, a waste clearance pathway, has been implicated in several neurological conditions associated with neuroinflammation. COVID-19 associated neurocognitive impairment, part of the post-acute sequelae of SARS-CoV-2 infection (PASC), is strongly associated with neuroinflammation and disrupted blood-brain barrier (BBB). Several studies have implicated a synergistic interaction between the glymphatic system dysfunction and BBB disruption. In this proof-of-concept study, we investigated the role of the MRI metric diffusion along the perivascular spaces DTI (DTI-ALPS) in patients with PASC and correlated this with the BBB capillary permeability metric- K trans derived from Dynamic contrast enhanced (DCE) perfusion.
