Low-dose MDCT of the abdomen and pelvis reduces hospital stay in patients with acute nonspecific abdominal pain

Extremely low-dose MDCT of the abdomen and pelvis is useful in providing needed diagnostic information and reducing hospital stay in patients with acute nonspecific abdominal pain, according to a new study by researchers from the Emory University School of Medicine in Atlanta, GA, and Massachusetts General Hospital in Boston, MA.

Study provides clues about inability to imitate and empathize in autistic children

New imaging research at UCLA shows that impairments in autistic children's ability to imitate and empathize can be linked to dysfunction in the brain's mirror-neuron system.

Social behavior differs in children with family history of autism

The baby brothers and sisters of autistic children do not seek emotional cues from adults, or respond to them, as often as other toddlers do, suggests new research from the University of California, San Diego.

Functional anesthetic discography allows diagnosis of lower back pain cause

Functional anesthetic discography (FAD), a new diagnostic procedure involving injecting anesthetic directly into a spinal disc, can be used to confirm the presence of injured discs as the source of a patient's lower back pain symptoms, according to a new study by researchers from Winthrop-University Hospital in Mineola, NY.

MDCT eliminates need for catheter angiography for aortic injury diagnosis

Contrast-enhanced 64-MDCT that definitively reveals acute trauma to the aorta does not need confirmation from invasive catheter angiography, which saves valuable time in treating patients in trauma centers, according to a new study by researchers from the Medical University of South Carolina in Charleston.

High intracoronary attenuation significantly improves diagnostic accuracy in 64-slice CT-CA of the coronary arteries

For the study, 170 patients with suspected coronary artery disease underwent CT-CA. The average vascular attenuation measured in the aortic root and in coronary arteries was used to divide the population into two groups of 85 patients each, one with low attenuations and one with high.

CT angiography has a nearly 100% detection rate in acute ruptured, cerebral aneurysms

CTA correctly detected the ruptured aneurysm in 170 cases when compared to intraoperative findings, Bijal Patel, MD, lead author of the study. Of the 22 cases where there was more than one aneurysm, CTA correctly identified the ones that were ruptured every time.
