MRI spots white-matter changes in movement disorder patients

People who suffer from idiopathic dystonia may have an underlying structural brain structure anomaly that contributes to the physical spasms that are manifest in the disorder, according to researchers from the University of South Carolina in Columbia. Using diffusion tensor MRI, they scanned patients with and without dystonia, and found white-matter abnormalities in the patients with the disorder.

Multislice CT almost as good as IVUS in acute coronary syndromes

BARCELONA - In the early stage of acute coronary syndrome, 16-slice multidetector-row CT can locate the culprit lesion, according to a presentation this week at the European Society of Cardiology's World Congress of Cardiology. Researchers from University Hospital in Bordeaux, France compared 16-slice CT to 40-MHz catheter-based intravascular ultrasound (IVUS).

Tracking and quantitative analysis of diaphragmatic motion and projected lung area (PLA) at dynamic chest radiography (DCR) in a 55-year-old healthy man during deep breathing. (A) Posteroanterior radiograph with purple and green lines indicating the right and left lateral diaphragm apices, respectively. (B) Graph of diaphragmatic motion (in millimeters; y-axis) over time (i.e., frame number; x-axis). The software tracked the position of the diaphragm apex at DCR to obtain these amplitude-time plots of diaphragmatic motion (right lung, purple; left lung, green). The dark blue line corresponds to the frame representing the end of inspiration; the light blue line corresponds to the frame representing the end of expiration. (C) Posteroanterior radiograph shows the PLA (outline), which is the area surrounded by the medial edge of the ribs, the diaphragm, and the edge of the mediastinum. (D) Graph of PLA (in millimeters squared; y-axis) over time (i.e., frame number; x-axis). The software automatically tracked the boundaries of the lung fields and obtained the time-varying curves of the bilateral lung field areas. The blue line corresponds to the frame representing the end of inspiration.
