Comparative Study
Femoroacetabular cam-type impingement: diagnostic sensitivity and specificity of radiographic views compared to radial MRI.
To retrospectively assess the diagnostic sensitivity of 45° Dunn view and cross-table lateral radiographs for the assessment of cam deformity by comparison with radial MRI. ⋯ The 45° Dunn view can improve the first line of impingement diagnostics. Radial MRI however remains indispensable for pre-operative planning and the evaluation of symptomatic cases without obvious deformity.

Case Reports
Transarterial Onyx packing of the transverse-sigmoid sinus for dural arteriovenous fistulas.
To report transarterial Onyx packing of the transverse-sigmoid sinus for dural arteriovenous fistulae (DAVFs). ⋯ Transarterial Onyx packing of transverse-sigmoid sinus for DAVFs via the meningeal arterial system is a safe therapeutic alternative in selected cases.

To assess the role of multidetector CT angiography (MDCTA) in the diagnosis of acute mesenteric ischemia (AMI) and to compare the diagnostic utility of axial images with reconstructed images. ⋯ MDCTA is an effective non-invasive modality for the diagnosis of mesenteric ischemia.

T2*-weighted MRI may represent a novel method for identifying hepatocellular carcinoma (HCC). The goal of this study was to assess the diagnostic accuracy of T2*-weighted MRI for HCC with liver explant correlation. ⋯ T2*-weighted MRI had a moderate sensitivity for identifying HCC but had an excellent specificity. A T2*-weighted MR sequence may be a useful component of a liver MRI protocol due to its high specificity for HCC, and may be particularly useful in patients unable to undergo gadolinium enhanced MRI.

Comparative Study
Comparison of three different injection methods for arterial phase of Gd-EOB-DTPA enhanced MR imaging of the liver.
To compare three different injection methods for optimizing hepatic arterial phase of gadolinium ethoxybenzyl diethylenetriaminepentaacetic acid (Gd-EOB-DTPA) enhanced MR imaging. ⋯ For the optimal arterial phase imaging, injection rate of 1 mL/s with undiluted Gd-EOB-DTPA is convenient and preferable, compared with other two methods, based on our qualitative analysis.
