Dual-source coronary CTA detects reduction in lumen diameter

Even in patients with high heart rates, dual-source coronary CT angiography (CTA) provides accurate detection of significant lesions, according to a preliminary study by Dutch investigators. One reason for dual-source CTA's success is technical advancements in the equipment, said the group from Erasmus Medical Center in Rotterdam, Netherlands.

ACC study: Dual-source cardiac CT delivers acceptable radiation dose

NEW ORLEANS - The radiation dose from dual-source CT (DSCT) is no more than that of single-source CT, according to a presentation this week at the American College of Cardiology (ACC) meeting. However, DSCT is not an option for patients with severe arrhythmia or a heart rate less than or equal to 55 beats per minute (bpm), they stressed.

ACOG study shows UFE is more cost-effective than surgery

Good news for patients, hospitals, and interventional radiologists: uterine fibroid embolization (UFE) is associated with less morbidity -- and lower costs -- than either hysterectomy or myomectomy, according to researchers from Jefferson Medical College at Thomas Jefferson University in Philadelphia.

Mammography affected by dense breasts in postmenopausal women

HAMBURG, GERMANY - Women in industrialized countries are having fewer children at later ages, and their breasts show it. The loss in breast density that typically occurs after menopause is not occurring as markedly in prior generations, and as a result, their mammograms may miss some tumors, according to a presentation this week at the European Breast Cancer Conference.
