Using positron emission tomography (PET) imaging with bioluminescence-the light produced by a chemical reaction within an organism-researchers are starting to understand the behavior of transplanted or implanted stem cells that may one day be used to develop new treatments for disease. (2007-12-07)
Twenty million nuclear medicine procedures that detect and evaluate heart disease, brain disorders and cancer-and that use radiopharmaceuticals to treat overactive thyroids and some cancers-are performed each year. (2007-12-07)

Researchers at Jefferson Medical College and Jefferson's Kimmel Cancer in Philadelphia have used PET imaging to see hyperactive cancer genes inside breast tumors in laboratory animals, marking the first time such gene activity has been observed from outside the body. (2007-11-29)
In the future, patients who arrive at a hospital Emergency Department complaining of chest pain may be diagnosed with a sophisticated CT scan. If the diagnosis is negative, the patient can go home-and the total time at the hospital will be much shorter than it is today. (2007-11-28)
Black and Hispanic women have a different understanding of screening mammography compared with that of Caucasian women. (2007-11-27)
Cleveland Clinic and Riverain Medical today announced the establishment of the first study in an ongoing program to determine whether chest X-ray CAD (computer-aided detection) can improve practical early detection of lung cancer. (2007-11-27)
Computed tomography (CT) angiography is as accurate as an invasive angiogram in detecting coronary artery disease, according to the findings of the first two prospective multicenter 64-slice scanner trials presented today at the annual meeting of the Radiological Society of North America (RSNA). (2007-11-27)
CT colonography (CTC), when used in elderly patients, can detect a high number of new and significant abnormalities outside the colon (including cirrhosis and tumors) and is well tolerated, according to a recent study conducted by researchers at St. James's University Hospital in Leeds, United Kingdom (UK). (2007-11-16)
Chemotherapy given at the same time as radiation therapy can help patients with a certain type of lung cancer live nearly 50 percent longer than they might have otherwise if the same treatment was given differently, according to an international team's analysis of several trial results. (2007-11-12)
New research comparing music conductors and non-musicians shows that both the conductors and the non-musicians "tuned out" their visual sense while performing a difficult hearing task. (2007-11-05)
Despite previous research suggesting that older adults are more distractible, new research shows they are no more distractible than younger adults when asked to focus their attention on their sense of sight or sound, or when asked to switch their attention from one sense to the other. (2007-11-05)
Adding ultrasound to mammography finds more cancers than mammography alone, but also substantially increases the number of false positives, according to first-year results from a three-year study of the two tests. (2007-10-01)
Researchers using functional magnetic resonance imaging (fMRI) have found a new marker which may aid in early diagnosis of Alzheimer's disease, according to a study published in the October issue of Radiology. (2007-09-25)
The study consisted of the review of approximately 12,000 emergency diagnostic imaging exams that were interpreted after hours by residents. (2007-09-24)
Having a healthy kidney is worth a billion dollars. But an unhealthy kidney costs more-about $16 billion more, according to Prabir Roy-Chaudhury, MD, PhD, associate professor in the division of nephrology and hypertension at the University of Cincinnati (UC). (2007-09-13)
New evidenced-based guidelines from the American College of Chest Physicians (ACCP) recommend against the use of low-dose computed tomography (LDCT) for the general screening of lung cancer. (2007-09-11)
