Two-dimensional aortographic coronary arteriography with above-K-edge monochromatic synchrotron radiation.

Rationale And Objectives: The diagnostic potential of two-dimensional aortographic coronary arteriography with synchrotron radiation was examined in dogs.

Methods: The experiment was performed at a wiggler beam line by using a silicon monocrystal, fluorescent plate, and avalanche-type camera. The x-ray energy was adjusted to just above the iodine K-edge to obtain the highest contrast.

High resolution MR imaging of the bilateral hips with dual phased-array coil.

We applied dual-flex coils in a phased-array configuration to obtain high resolution MR images of the bilateral hips and compared the image quality with non-phased-array imaging. Multiple fast spin-echo images of both hips were obtained in a single acquisition. Two consecutive acquisitions with and without phased-array capability were performed in 22 hips and a fluid-filled phantom.
