New research shows that the addition of two magnetic resonance imaging (MRI) sequences to a common MR angiography technique significantly improves detection of pulmonary embolism, a potentially life-threatening condition traditionally diagnosed through computed tomography (CT). Results of the study are published online in the journal Radiology. Pulmonary embolism occurs when a blood clot–usually from the leg–travels to the lung and blocks the pulmonary artery or one of its main...

A new study by Brigham and Women's Hospital (BWH) researchers found significant variation in the use of head computed tomography (CT) exams among doctors within the emergency department (ED). With advanced imaging as a driver of increasing health care costs, strategies to reduce variation in head CT use and other high-cost imaging studies may reduce cost and improve quality of care. This study is part of an effort by researchers at BWH to develop strategies for achieving the appropriate...

New research from the University of Calgary's Hotchkiss Brain Institute shows that by using a CT scan (computerized tomography), doctors can predict which patients are at risk of continued bleeding in the brain after a stroke. This vital information will allow doctors to utilize the most powerful blood clotting medications for those with the highest risk. One in three individuals will continue to accumulate blood in the brain from a leak in a small artery. Pooling blood in the brain has...

For assessing severe trauma, single-pass whole-body computed tomography (CT) can prove but not definitively exclude the presence of injuries and should be performed later than 30 minutes after admission to an emergency department for optimal results, according to a study in CMAJ (Canadian Medical Association Journal). Traumatic injury, caused by major traffic collisions or a fall from a height, for example, has a significant impact on health care costs, illness and death. In North America...

Initial tests show promising results of new ultrasonic screening technique Scientists have successfully completed an initial trial of a new, potentially more reliable, technique for screening breast cancer using ultrasound. The team at the National Physical Laboratory (NPL), the UK's National Measurement Institute, working with the University Hospitals Bristol NHS Foundation Trust, are now looking to develop the technique into a clinical device. Annually, 46,000 women are diagnosed with...

Imaging amino acid transporters with positron emission tomography/computed tomography (PET/CT) has been shown to significantly alter intended management plans for patients with brain tumors, according to research in the March issue of The Journal of Nuclear Medicine. As a result of imaging with the radiopharmaceutical 3,4-dihydroxy-6-F-18-fluoro-l-phenylalanine (F-18-DOPA), physicians changed the intended management plan for 41 percent of patients with brain tumors. Contrast-enhanced...

Computed tomography (CT) colonography can be used as a primary screening tool for colorectal cancer in adults over the age of 65. Some previous medical studies have found no significant difference in the diagnostic accuracy of CT colonography, also known as "virtual colonoscopy," and traditional optical colonoscopy. This study looks at whether both exams are as effective for adults over 65 as they are for adults between 50 and 65 years of age. In the study, C. Daniel Johnson, M.D.,...
