Contrast US pinpoints focal liver lesions, results in cost-savings

By N. Shivapriya

Contrast-enhanced ultrasound (CEUS) can be an effective way to characterize focal liver lesions (FLL), and may offer potential cost-savings, according to two separate European studies.

Valsalva maneuver takes a leading role in MDCT of hernias

By Radiology Review

(Radiology Review) Radiologists at Duke University Medical Center in Durham, NC, evaluated the role of the Valsalva maneuver during MDCT of patients with suspected abdominal wall hernias, and found that scans acquired with the maneuver detected more hernias than without it.

Panoply of VC studies yields significant extracolonic findings

By Eric Barnes

A meta-analysis of VC studies has enumerated what radiologists have been noticing for years: that VC reveals important incidental abnormalities. The findings deemed "important" ranged from abdominal aortic aneurysms to early extracolonic cancers -- the latter detected at rates equivalent to that of breast cancer screening. The U.K. authors could only conclude that VC may become an important method of detecting early extracolonic cancers.

Contrast US tops conventional US for blunt liver trauma

By Radiology Review

(Radiology Review) Contrast-enhanced ultrasound (CEUS) can effectively evaluate blunt hepatic trauma, and has superior sensitivity compared to sonography without contrast enhancement, according to Italian radiologists.

Evidence-based practice shows PET superior to CT, MR for staging colorectal liver metastases

By Jonathan S. Batchelor

A traditional imaging workup for colorectal carcinoma liver metastases (CCLM) calls for a CT scan followed by ultrasound and MR for disease staging and patient management. However, a research team in Ireland used the five-step process of evidence-based medicine to successfully implement new protocols for CCLM that utilize PET as the primary imaging modality.

Proof of concept seen in microCT mouse VC

By Eric Barnes

Hot on the tail of the first mouse MR colonography study, investigators in Wisconsin have established a technique to perform microCT virtual colonoscopy in 20 murine subjects from Madison.

Breath-hold technique comparable to respiratory-triggered MR for liver imaging

By Radiology Review

(Radiology Review) Breath-hold fat-suppressed fast-recovery FSE T2-weighted images of the liver were superior to those of respiratory-triggered fat-suppressed FSE T2-weighted imaging, according to radiologists at David Geffen School of Medicine in Los Angeles.

Aortic wall compliance useful in evaluating AAA risk noninvasively

By N. Shivapriya

Wall compliance and stiffness measurement may be useful in evaluating the success of endovascular repair for abdominal aortic aneurysms (AAA), according to a study by U.K. researchers.

VC experts have an edge over less experienced readers

By Eric Barnes

VIENNA - The correct categorization of polyp size at virtual colonoscopy is crucial to patient management. Researchers of a multicenter study tested three reader groups and found wide variations between endoscopically and radiologically reported lesion sizes, and only subtle differences among the three groups in their ability to categorize lesions on VC software.

New VC CAD applications show promise as second reader

By Eric Barnes

The first large multicenter trial of a VC CAD scheme is showing real promise, with high sensitivity and specificity for detecting colorectal polyps. And another recent study from Japan shows that CAD can improve the ability to detect colorectal polyps by everyone who uses it.
