Rapid advancements in multidetector row computed tomography (MDCT) are beginning to revolutionise cardiac imaging applications. As a consequence, coronary CT angiography (CTA) is fast emerging as a highly effective, noninvasive imaging technique for the assessment of coronary artery disease (CAD). ⋯ However, this rapid progress has meant that we are also adding to the growing list of additional potential applications of CTA that are possible with the technology. The aim of this review is to present an overview of the technical capabilities of cardiac MDCT relating to coronary CTA and other applications, the limitations of current technologies, as well as discuss political perspectives and how to address these in medical practice.

The HydroCoil Embolic System (HES) was developed to reduce recurrences of aneurysms relative to platinum coils. But the HydroCoil Embolic System was characterized with many limitations. The manufacturer had recognized the challenge and recently a new design of hydrogel-coated coil-HydroSoft has become available in the market as the new generation HydroCoil. We reported our initial experience using HydroSoft coil versus HydroCoil in our center. ⋯ HydroSoft coil allowed us to deploy coated coils with good packing density. A slight expansion of these coils at the neck can be expected to reduce neck remnant and potentially inhibit recurrence.

The purpose of this study was to determine transit times for excretion of Gd-EOB-DTPA into different segments of the hepatobiliary system in patients with normal liver function. ⋯ Within 20 min post contrast initiation, Gd-EOB-DTPA can be expected in the IBD and the CBD in patients with normal liver function. However, functional information about the sphincter Oddi complex can be ascertained only in about two thirds of these patients within this timeframe.

Comparative Study
Image quality of T2w-TSE of the abdomen and pelvis with Cartesian or BLADE-type k-space sampling: a retrospective interindividual comparison study.
The purpose of this study was to evaluate the image quality of T2-weighted (T2w) imaging of the abdomen and pelvis based on the acquisition of rotating rectangular stripes of k-space data after successive radiofrequency excitation (BLADE technique) in comparison to T2w turbo-spin-echo (TSE) sequences with Cartesian k-space sampling. ⋯ In imaging of the pelvis the overall quality of T2w sequences with k-space sampling in BLADE technique was rated significantly superior compared with the standard Cartesian sampling. Similar results were assessed for the reduction of the amount of artifacts and blurring. By contrast, no significant benefit could be demonstrated for the T2w-BLADE in the abdomen.

The purpose of the study was to evaluate unenhanced Magnetic Resonance Imaging (MRI) for the diagnosis of appendicitis or another surgery-requiring condition in an adult population scheduled for emergency appendectomy based on a clinical diagnosis of suspected acute appendicitis. ⋯ Unenhanced fast MRI is feasible as an additional fast screening before the appendectomy. It may prevent unnecessary surgeries. The fast MRI examination can be adequately performed on an MRI unit of broad range of field strengths.
