466. Study of MR-Cholangiography using various coil

Staging of rectal carcinoma using MR double surface coil, MR endorectal coil, and intrarectal ultrasound: correlation with histopathologic findings.

OBJECTIVE Our goal was assessment of the preoperative staging of rectal carcinoma with MR with double surface coil, MR with endorectal coil, and intrarectal ultrasound (IUS) as correlated with histopathologic findings. MATERIALS AND METHODS Fifteen patients with rectal carcinoma had preoperative evaluation using intrarectal ultrasound (all 15 patients), MR with double surface coil alone (6 pa...

non-linear study of various slit shear walls in steel structures

seismic retrofit strategies have been developed in the past few decades following the introduction of new seismic provisions and the availability of advanced materials and methods. it can be observed that new approaches to deal with more lateral forces are more innovative and more energy absorbent. in line with this, there is a growing trend toward the use of steel shear walls as a system with ...

MR-Elastography of the prostate using an endorectal coil for actuation - a feasibility study

Simplified cholangiography using ioglycamide.

Intravenous cholangiograms were performed on 100 unselected nonicteric patients using methylglucamine ioglycamide (Biligram). Fifty patients received 10.5 g of contrast medium and 50 received 5.25 g of medium. The contrast medium was injected evenly over five minutes. Side effects were recorded in only 13% of patients and all were mild. Radiographs were taken 10, 30, 60, 90, and 120 minutes aft...

Body-coil nonenhanced MR angiography using highly undersampled radial QISS

Background Current approaches for magnetic resonance angiography (MRA) require the use of parallel imaging in order to keep scan times short and obtain adequate slice coverage and spatial resolution. However, parallel imaging necessitates the use of phased array coils, which increases setup time and restricts the vascular territory that can be imaged. We hypothesized that using Quiescent-Inflow...
