A University of Wisconsin study has found that U.S. hospitals and outpatient clinics have enough excess multislice CT capacity to handle an expected increase in demand for CT screening colonography without adding new equipment. More »
Venous ultrasonography may be an extraneous step in the diagnosis of pulmonary embolism. A D-dimer test performed with multislice CT scan is no less sensitive than the two tests performed in combination with venous ultrasound of the leg, according to a study from Switzerland. More »
A clinical study to determine computer-aided detection’s value to CT colonography could save manufacturers time and money by speeding up the regulatory approval process. If proven successful, the approach could save thousands of lives each year by enhancing early colorectal cancer detection. More »
Reports of the demise of the D-dimer test for suspected pulmonary embolism may be greatly exaggerated, according to two new studies. Multislice CT angiography has become the de facto standard for pulmonary embolism detection, but researchers in Illinois and Hawaii have shown the inexpensive blood... More »
Radiation protection watchdogs have raised the alarm over increasing utilization of CT, particularly in the emergency room. But a prospective study from Harvard University so far shows that CT’s benefits may outweigh the risks, at least for triaging abdominal pain. More »
A large multicenter trial rates FDG-PET as more reliable than CT for the detection of malignant solitary pulmonary nodules. The findings suggest, however, that a combined rather than single-modality approach may lead to earlier treatment and help avoid invasive procedures. More »
Calcium deposits in coronary arteries provide a strong predictor for incidence of heart attack and cardiac disease, and detecting such deposits via CT scanning can help promote overall cardiac health in racially and ethnically diverse populations, according to a new study in March 28 issue of The...

Results from an international trial involving 44 sites have confirmed that the routine clinical use of cardiac CT angiography exposes patients to large amounts of ionizing radiation. The amount of radiation exposure varies considerably, suggesting that users have not uniformly adopted dose-reducing... More »
Medicare’s decision against a national coverage determination for cardiac CT is not the end of conflict for the modality. It is just the beginning. More »
The always-controversial International Early Lung Cancer Action Program has been struck a serious blow with news that the trial was funded by a cigarette manufacturer, according to an article in Wednesday’s New York Times.More »
