New research has found that the availability of a portable eight-slice computed tomography (CT) scanner in an emergency room can significantly increase the number of stroke victims who receive a potentially life-saving treatment.

Following the introduction of the first-ever dual-source Computed Tomography (CT) system, SOMATOM® Definition, with two X-ray tubes that simultaneously generate different energies, Siemens Healthcare has developed 10 dual energy (DE) applications.

In the current issue of the journal Circulation, a research team from the Medical University of South Carolina’s (MUSC) Heart & Vascular Center report their initial experience with a novel imaging technique that enables comprehensive diagnosis of heart disease based on a single computerized tomographic (CT) scan.

Aiming to promote the best medical imaging practices nationwide and help ensure the health and safety of the millions of people who undergo computed tomography (CT) scans each year in the United States, the American Association of Physicists in Medicine (AAPM) has issued a CT radiation dose management report this month recommending standardized ways of reporting doses and educating users on the latest dose reduction technology.

Researchers involved in a large, multi-institutional study comparing the accuracy of positron emission tomography (PET) and computed tomography (CT) in the characterization of lung nodules found that PET was far more reliable in detecting whether or not a nodule was malignant.

Cone-beam breast CT provides exceptional tissue contrast and can potentially reduce examination time with comparable radiation dose to conventional 2D mammography, according to a new study by a team of researchers from the University of Texas M. D. Anderson Cancer Center in Houston.

Concerns over possible radiation effects of CT scans detailed in a report yesterday in the New England Journal of Medicine should not scare people away from getting medically needed CT scans, as the scans play a critical role in saving the lives of thousands of people every day, according to an official with the American Association of Physicists in Medicine (AAPM).

If adrenal masses are found incidentally during a CT scan, and the masses look benign, they do not require additional imaging follow-up, according to a recent study conducted by researchers at Brown University in Providence, Rhode Island.

Radiologists are investigating the use of computed tomography (CT) as a tool for civilian medical examiners’ autopsies in the United States. According to findings presented today at the annual meeting of the Radiological Society of North America (RSNA), CT autopsy has the potential to replace conventional autopsy in determining the cause of certain accidental deaths.

The female patient, reported on the December 7 issue 45 of World J Gastroenterology, presented a rare case, with symptoms consistent with hyperadrenocorticism and hypercatecholaminism, and also had a Cushingoid appearance. The serum cortisol, dopamine and noradrenalin levels were elevated. Computed tomography detected a left adrenal mass measuring 3.5 cm -- 3.0 cm in diameter.

A study by an international team of cardiac imaging specialists, led by researchers at Johns Hopkins, concludes that sophisticated computed tomography (CT) scans of the heart and its surrounding arteries are almost as reliable and accurate as more invasive procedures to check for blockages.

A new imaging technology may hold the key to not only stopping heart attacks in their tracks but also preventing them for ever occurring. For the first time, researchers at Mount Sinai School of Medicine have shown the use multi-detector computed tomography (CT) imaging along with a novel contrast agent know as N1177 can detect dangerous, high-risk plaque which cause heart attack and stroke.
