Small hepatocellular carcinoma: MRI findings for predicting tumor growth rates.

Rationale And Objectives: Current clinical practice favors imaging rather than biopsy to diagnose hepatocellular carcinoma (HCC). There is a need to better understand tumor biology and aggressiveness of HCC. Our goal is to investigate magnetic resonance imaging (MRI) features of HCC that are associated with faster growth rates (GRs).

Diffusion-weighted imaging (DWI) of adenomyosis and fibroids of the uterus.

Purpose: Although magnetic resonance imaging is often able to distinguish between adenomyosis and fibroids, occasionally the imaging features of focal adenomyosis and fibroids overlap. Diffusion-weighted imaging (DWI) may provide useful information in differentiating pathologies. Therefore, the purpose of our study was to evaluate differences, if any, in the apparent diffusion coefficient (ADC) values of fibroids and adenomyosis.

Breast ultrasound diagnostic performance and outcomes for mass lesions using Breast Imaging Reporting and Data System category 0 mammogram.

Purpose: To evaluate the outcomes and diagnostic performance of ultrasonography after a Breast Imaging Reporting and Data System (Bi-RADS) category 0 mammogram.

Material And Methods: This retrospective study reviewed 4,384 consecutive patients who underwent a screening mammography from January 2005 to July 2006; 391 of the 4,384 exams were classified as Bi-RADS category 0. After exclusions, 241 patients received subsequent sonogram.
