State-of-the-art 64-slice CT is proving its worth as a potent noninvasive tool for imaging coronary arteries, but it has some noteworthy limitations, according to research presented at the ECR on Tuesday.
A whole-body PET/CT scan can be used to stage and further pinpoint cancers spotted on optical colonoscopy, a research team for Essen University reported Monday. The team also reported that PET/CT scans may be useful in restaging recurrent breast cancer.
Philips Medical Systems chose opening day of the ECR to release the world’s first commercial time-of-flight PET/CT system. The system, scheduled to begin shipping to sites in Europe and the U.S. in June, will more than double image sensitivity, according to the company, allowing users to either markedly improve image quality or cut scan time by a third or more.
New computer-aided detection programs help less experienced readers find clinically significant polyps with CT colonography, but they prove less useful for experts, according to three studies presented at the ECR on Saturday.
Agfa HealthCare plans to distinguish itself in a crowded IT market by providing meaningful integration of different sources of clinical data and bringing the results into clinical workflow, company officials said at the ECR.
CT and MR angiography both provided more clinically useful information than duplex ultrasound in screening peripheral vascular disease. But when costs are factored in, CT emerged as the clear leader, according to a four-hospital study conducted in the Netherlands and described Saturday.
MR offers decided advantages as a tool for image guidance in radiofrequency ablation of liver tumors, but it also presents significant problems that must be overcome before its use becomes widespread, according to a pair of presentations March 5 at the European Congress of Radiology.
MR colonography has yet to capture radiologists’ imagination to the same extent as CT. But the radiation-free exam has a bright future, especially if stool tagging techniques can avoid the need for bowel cleansing, according to speakers from the U.S. and Greece at ECR on Friday.
Low-dose CT can effectively replace plain film in cases of acute abdominal pain, with benefits for clinical diagnosis, according to a study by Swedish researchers presented at the ECR Friday afternoon.
Radiology in Asia is booming. The demand for radiology services is growing, and investment made by governments and private hospitals and companies in imaging equipment and radiology departments is increasing rapidly every year. This includes investments in PACS, RIS, and teleradiology networks.
