Autor: Kristen N Bird, Aya Kamaya, R. Brooke Jeffrey, Tie Liang, Marcelina G. Perez, Justin R. Tse

Publikováno v: Abdominal Radiology. 46:4720-4728

To evaluate angle-corrected peak systolic cystic artery velocity (CAv) as a predictor of acute cholecystitis among patients presenting to the emergency department (ED) with right upper quadrant (RUQ) pain. In this IRB-approved and retrospective study

Non-invasive assessment of cirrhosis using multiphasic dual-energy CT iodine maps: correlation with model for end-stage liver disease score

Autor: Domenico Mastrodicasa, Virginia Hinostroza, R. Brooke Jeffrey, Bhavik N. Patel, Lior Molvin, Celina Duran, Andrea Delli Pizzi, Martin J. Willemink, Mohamed H. Khalaf

Publikováno v: Abdom Radiol (NY)

PURPOSE: To determine whether multiphasic dualenergy (DE) CT iodine quantitation correlates with the severity of chronic liver disease. METHODS: We retrospectively included 40 cirrhotic and 28 non-cirrhotic patients who underwent a multiphasic liver

Ileocolic vascular curvature: a new CT finding of cecal volvulus

Autor: Adam N. Rucker, R. Brooke Jeffrey, Margaret Tze Tung Wong, Eric W. Olcott

Publikováno v: Abdominal Radiology. 45:3057-3064

To evaluate the diagnostic performance of a proposed new CT observation in cecal volvulus, marked hook-like curvature of ileocolic vessels termed “ileocolic vascular curvature.” Contrast-enhanced CT scans of 14 patients with diagnoses of cecal vo

Cost-effectiveness of dual-energy CT versus multiphasic single-energy CT and MRI for characterization of incidental indeterminate renal lesions

Autor: Pari V. Pandharipande, Artem Boltyenkov, R. Brooke Jeffrey, Avinash Kambadakone, Maria G Martinez, Domenico Mastrodicasa, Benjamin I. Chung, Daniele Marin, Bhavik N. Patel

Publikováno v: Abdominal Radiology. 45:1896-1906

To evaluate the cost-effectiveness of DECT versus multiphasic CT and MRI for characterizing small incidentally detected indeterminate renal lesions using a Markov Monte Carlo decision-analytic model. Incidental renal lesions are commonly encountered

Autor: Bhavik H. Patel, Akshay Jaggi, Gregory W. Charville, Domenico Mastrodicasa, R. Brooke Jeffrey, Sandy Napel

Publikováno v: J Med Imaging (Bellingham)

Purpose: To differentiate oncocytoma and chromophobe renal cell carcinoma (RCC) using radiomics features computed from spherical samples of image regions of interest, "radiomic biopsies" (RBs). Approach: In a retrospective cohort study of 102 CT case
