Ct And Pet Findings For Urachal Adenocarcinoma: A Case Report, Merissa Zeman, Ethan Silver, Esma A. Akin

Radiology Faculty Publications

As urachal adenocarcinomas are rare cancers, experience with diagnosing and staging them are limited. To help illustrate CT and PET imaging findings and the role they each play in the workup of urachal adenocarcinomas, we present the case of a 43 y.o. male who was diagnosed at our institution with a T3aN0M0 high grade mucin-producing urachal adenocarcinoma.

Composite Iron Oxide–Prussian Blue Nanoparticles For Magnetically Guided T1-Weighted Magnetic Resonance Imaging And Photothermal Therapy Of Tumors, Shraddha Kale, Rachel Burga, Elizabeth E. Sweeney, Zungho Zun, Raymond Sze, Anthony Tuesca, J Anand Subramony, Rohan Fernandes

Theranostic nanoparticles offer the potential for mixing and matching disparate diagnostic and therapeutic functionalities within a single nanoparticle for the personalized treatment of diseases. In this article, we present composite iron oxide-gadolinium-containing Prussian blue nanoparticles (Fe3O4@GdPB) as a novel theranostic agent for T1-weighted magnetic resonance imaging (MRI) and photothermal therapy (PTT) of tumors. These particles combine the well-described properties and safety profiles of the constituent Fe3O4 nanoparticles and gadolinium-containing Prussian blue nanoparticles. The Fe3O4@GdPB nanoparticles function both as effective MRI contrast agents and PTT agents as determined by characterizing studies performed in vitro and retain their properties in the presence …

Prospective Evaluation Of The Influence Of Iterative Reconstruction On The Reproducibility Of Coronary Calcium Quantification In Reduced Radiation Dose 320 Detector Row Ct., Andrew D. Choi, Eric S Leifer, Jeannie Yu, Sujata M Shanbhag, Kathie Bronson, Andrew E Arai, Marcus Y Chen

BACKGROUND: Coronary artery calcium (CAC) predicts coronary heart disease events and is important for individualized cardiac risk assessment. This report assesses the interscan variability of CT for coronary calcium quantification using image acquisition with standard and reduced radiation dose protocols and whether the use of reduced radiation dose acquisition with iterative reconstruction (IR; "reduced-dose/IR ") allows for similar image quality and reproducibility when compared to standard radiation dose acquisition with filtered back projection (FBP; "standard-dose/FBP") on 320-detector row computed tomography (320-CT).

METHODS: 200 consecutive patients (60 ± 9 years, 59% male) prospectively underwent two standard- and two reduced-dose acquisitions (800 …
