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.

Two cases of pathologically confirmed intrahepatic cholangiocarcinomas in 68-year-old male patients. In both cases (A-H, case 1; I-P, case 2), CT scans (B, F, case 1; J, N, case 2) revealed intrahepatic bile duct dilation and suspected nodular lesions. While F-18 FDG PET/CT (A, C, D, case 1; I, K, L, case 2) failed to demonstrate abnormal tracer uptake (SUVmax 3.5, TBR 1.3 in Case 1; SUVmax 2.6, TBR 1.2 in Case 2), F-18 FAPI-04 PET/CT (E, G, H, case 1; M, O, P, case 2 ) showed positive uptake in the nodular lesions (SUVmax 9.7, TBR 3.5 in Case 1; SUVmax 9.6, TBR 3.3 in Case 2).

The number of all visible structures was fewer at an ambient light of 500 lux compared to both 25 and 75 lux. In addition, structure visibility was better with a gray wall color at all ambient light levels. Paired comparison between monitors showed better structure visibility on the high specification monitor for all condition.
