To assess information regarding radiology practices on public transparency Web sites. ⋯ Transparency Web sites had a preponderance of price (and to a lesser extent service quality) information, risking fostering price-based competition at the expense of clinical quality.

Comparative Study
Comparison of high-resolution T1W 3D GRE (LAVA) with 2-point Dixon fat/water separation (FLEX) to T1W fast spin echo (FSE) in prostate cancer (PCa).
To compare T1-weighted (T1W) fast spin echo (FSE) to T1W 3-dimensional gradient recalled echo (LAVA) with fat water separation (FLEX) in prostate cancer (PCa). ⋯ T1W LAVA FLEX improves image quality, lessens motion artifact, and is comparable or improves detection of metastases in PCa with reduction in acquisition time.

Abdominal aortic aneurysm (AAA) development is a multifactorial process that is more prevalent among people ≥65years of age. Major risk factors are obesity, male sex, history of smoking (at least 100 cigarettes in a person's lifetime), and history of AAA in a first-degree relative. The United States Preventative Task Force has recommended a one-time ultrasound screening for men aged 65-75years. Based on studies, negative results on a single ultrasound examination around the age of 65years appear to virtually exclude the risk for future AAA rupture or death. While ultrasonography (US) is the confirmatory study of choice, computed tomography (CT) can also be used in the diagnosis of AAA. The goal of this study is to determine if AAA rupture can reliably be excluded in individuals with abdominal pain who have had a normal caliber aorta on CT or US after the age of 65years. ⋯ Based on these results, it appears that AAA and rupture may reliably be excluded in ED patients with abdominal pain who have previously had a normal caliber aorta on CT or US after the age of 65years. A prospective, multicenter study would help validate these findings.

To evaluate the potential of intravoxel incoherent motion (IVIM) imaging to predict histological prognostic parameters by investigating whether IVIM parameters correlate with Gleason score. ⋯ The pure molecular diffusion parameter, D, was the IVIM parameter that best discriminated prostate cancers with low Gleason scores from prostate cancers with intermediate or high Gleason scores.

To evaluate the left distal thoracic duct (DTD) in the lower neck area by using contrast-enhanced chest computed tomography (CT) in patients with liver cirrhosis (LC). ⋯ When reviewed the contrast-enhanced chest CT, the left DTD can be identified more frequently in subjects with LC than in those with noncirrhotic liver. Furthermore, the degree of left DTD dilation may be associated with the severity of LC.
