Ultrasound News and Research

RSS

Ultrasound is a procedure in which high-energy sound waves are bounced off internal tissues or organs and make echoes. The echo patterns are shown on the screen of an ultrasound machine, forming a picture of body tissues called a sonogram. Also called ultrasonography.

Ovarian cancers detected early may be less aggressive, questioning effectiveness of screening

The biology of ovarian cancers discovered at an early stage may render them slower growing and less likely to spread than more aggressive cancers, which typically are discovered in an advanced stage, according to a study led by investigators in the Duke Comprehensive Cancer Center.

Combination of very low LDL and normal systolic blood pressure attenuate coronary artery disease

New data published in the March 31, 2009, issue of the Journal of the American College of Cardiology show that patients with coronary artery disease (CAD) who achieve very low levels of low-density lipoprotein (LDL) cholesterol along with normal systolic blood pressure have the slowest progression of CAD.

Interventional treatment can be recommended as first-line treatment for 'silent killer'

Endovascular or endograft repair, a minimally invasive interventional radiology treatment that uses stent grafts to treat abdominal aortic aneurysms (AAA), has low re-intervention rates that are comparable to those reported for open surgical repair-and can be recommended as first-line treatment, according to a study released at the Society of Interventional Radiology's 34th Annual Scientific Meeting.
