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.

MDCT catches stenoses up to 4 mm in large coronary vessels
Using a 75% threshold, Japanese and U.S. investigators found that 64-slice multidetector-row CT (MDCT) could accurately diagnose coronary artery stenosis, according to a presentation at the 2007 American College of Cardiology (ACC) meeting in New Orleans.

64-slice CTA upheld as dependable test for ruling out CAD
Sixty-four-slice coronary CT angiography (CTA) is a reliable alternative to conventional coronary angiography for excluding coronary artery disease (CAD) in patients with diverse clinical presentations, according to Dutch researchers.

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.

Osteoporosis drug may protect women with family history of breast cancer
SAN FRANCISCO - The selective estrogen receptor modulator (SERM) raloxifene is associated with a reduced risk of invasive breast cancer, particularly among postmenopausal women with a family history of breast cancer, according to a presentation this week at the American College of Obstetrics and Gynecology (ACOG) meeting.

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.

Enzyme found in bat saliva enhances MRI of thrombolysis
SAN DIEGO - Vampire bat saliva can be used up to nine hours after an ischemic stroke for thrombolysis, with follow-up MR detection, according to a presentation this weekend at the American Heart Associaton's International Stroke Conference.

What’s the best treatment for 'eloquent' brain AVMs?
Researchers performed the first direct comparisons of two emerging techniques for treating arteriovenous malformations (AVMs).
Images in a 49-year-old patient originally treated for hormone receptor-positive invasive cancer without preoperative MRI who developed bloody nipple discharge two years after surgery. (A) Left mediolateral oblique mammogram shows new grouped pleomorphic calcification (arrow) adjacent to the previous operation site. (B) Transverse ultrasound image shows a 2.3-cm hypoechoic mass (arrows) with calcifications. (C) Axial contrast-enhanced fat-saturated T1-weighted MRI scan shows an irregular, heterogeneously enhancing mass (arrow) in the left breast, adjacent to the operation site. The final pathologic examination confirmed recurrent invasive ductal carcinoma.
