Paraumbilical Collateral Veins On Mri As Possible Protection Against Portal Venous Thrombosis In Candidates For Liver Transplantation, Sachit Verma, Donald G. Mitchell, Yulia Lakhman, Diane Bergin, Ronald J. Dolin, Cataldo Doria, Laurence Parker

Department of Radiology Faculty Papers

Background: We retrospectively evaluate the potential protective influence of patent paraumblical vein (PUV) collaterals against portal vein (PV) thrombosis and reduced PV diameter in candidates for orthotopic liver transplant (OLT)

Methods: Dynamic 3D contrast-enhanced MRI at 1.5T was obtained in 309 patients with cirrhosis without evidence of malignancy. All MR studies were reviewed by one reader for PUV collaterals, PV thrombosis and PV diameter. Statistical analysis was performed by Fisher exact tests; 50 selected studies were reviewed independently by two additional readers to determine interobserver agreement via intraclass correlation coefficient (ICC).

Results: Patent PUV was noted in …

Turf Wars In Radiology: What Must Academic Radiology Do?, Vijay M. Rao, David C. Levin

Department of Radiology Faculty Papers

In a previous article in this series, we called upon private practice radiology groups to better support radiology research financially, but also pointed out that academic radiology must make some changes as well. In this article, we discuss those changes in detail. They include revising the structure of the radiology residency, changing the timing of the American Board of Radiology oral examinations, requiring that all residents receive research training, and emphasizing the value of clinical and translational research. The Society of Chairmen of Academic Radiology Departments (SCARD) needs to assume a leadership role in implementing these changes.

Comparison Of Contrast Enhanced Color Doppler Targeted Biopsy To Conventional Systematic Biology: Impact On Gleason Score, M. Mitterberger, G. M. Pinggera, W. Horninger, G. Bartsch, H. Strasser, G. Schafer, A. Brunner, Ethan J. Halpern, J. Gradl, L. Pallwein, F. Frauscher

Purpose: Prostate cancer grading with Gleason score is an important prognostic factor. This prospective randomized study compares ultrasound systematic biopsy vs contrast enhanced color Doppler targeted biopsy for the impact on Gleason score findings.

Materials and Methods: We examined 690 men (mean age 56 years, range 41 to 77) with a serum total prostate specific antigen of 1.25 ng/ml or greater, a free-to-total prostate specific antigen ratio less than 18% and/or a suspicious digital rectal examination. Contrast enhanced color Doppler targeted biopsies with a limited number of cores (5 or less) were performed in hypervascular areas of the peripheral zone …
