Multi-Detector Row CT Imaging of Vertebral Microstructure for Evaluation of Fracture Risk

Multi-detector row CT urography in the evaluation of hematuria.

Hematuria can be well evaluated with a comprehensive contrast material-enhanced multi-detector row computed tomography (CT) protocol that combines unenhanced, nephrographic-phase, and excretory-phase imaging. Unenhanced images are obtained from the kidneys to the bladder and allow optimal detection of renal calculi, a common cause of hematuria. Renal parenchymal abnormalities, particularly mass...

Imaging evaluation of osteoporotic vertebral fracture.

As the world's population ages, the incidence of osteoporosis defined by decreased bone mass and alteration of microarchitecture has inevitably increased. This results in osteoporosis-associated fracture and leads to debilitating health outcomes and a considerable economic burden on the health care system. In this issue of the Journal of the Chinese Medical Association, Lin and colleagues have ...

Dosimetric evaluation of a 320 detector row CT scanner unit

BACKGROUND The technologic improvements in Multislice scanners include the increment in the X-ray beam width. Some new CT scanners are equipped with a 320 detector row which allows a longitudinal coverage of 160 mm and a total of 640 slices for a single rotation. When such parameters are used the length of the traditional pencil chamber (10 cm) is no more appropriate to measure the standard wei...

Three-dimensional imaging of thoracic diseases with multi-detector row CT.

The benefits of multi-detector row CT (MDCT) relative to single-detector row helical CT are considerable. Multi-detector row CT allows shorter acquisition times, greater coverage, and superior image resolution. These factors substantially increase the diagnostic accuracy of the examination. Three-dimensional (3D) volume data from MDCT provides various unique applications on thoracic diseases. T...
