Physicians should review a patient's computed tomography imaging history and cumulative radiation dose before doing another CT exam, U.S. researchers say. The study of 130 patients who had at least three emergency department visits within one year, published in the American Journal of Roentgenology, found that half had undergone 10 or more CT scans in the previous eight years, up to a maximum of 70 CT scans. Researchers at Brigham and Women's Hospital in Boston and Washington University...

Physicians should review a patient's CT imaging history and cumulative radiation dose when considering whether to perform another CT exam, according to researchers at Brigham and Women's Hospital, Boston, MA, and Washington University School of Medicine, St. Louis, MO. The study included 130 patients who had at least three emergency department visits within one year in which they had a CT scan of the neck, chest, abdomen or pelvis. "We gathered the recent CT exam histories for each of these...

Radiologists can now lower the radiation dose delivered by cardiac CT angiography by 39% in adult patients weighing 185 pounds or less, according to a study performed at the University of Erlangen in Erlangen, Germany.The study included one hundred patients, weighing 185 pounds or less, who underwent cardiac CT angiography either using a tube voltage of 120 kV or 100 kV. Results showed that the effective radiation dose for patients scanned with 120 kV ranged from 8.8 to 16.9 mSv; the...

Physicians can dramatically reduce the radiation dose delivered to patients undergoing coronary CT angiography in a "triple rule-out" protocol by simply using tube current modulation, according to a study performed at Thomas Jefferson University Hospital in Philadelphia, PA.The study included 172 patients who were evaluated using coronary CT angiography without tube current modulation and 95 patients who were evaluated with tube current modulation. The effective radiation dose ranged between...

 CT scans are great at helping doctors determine what's wrong. But too many of these scans might be promoting illness rather than helping to diagnose it.According to Boston researchers, having too many CT scans raises the risk of radiation-induced cancer.The investigators arrived at that conclusion after looking at more than 31,000 patients who underwent more than 190,000 CT scans over a 22-year period. Among the group, 33 percent had five or more scans. Five percent had more than 22 of...

A lifetime of computed tomography -- detailed X-ray images of internal organs -- may increase cancer risks for some patients, U.S. researchers say. CT is an excellent diagnostic tool of tremendous clinical value in many situations, Dr. Aaron Sodickson of Boston's Brigham and Women's Hospital and the Center for Evidence-Based Imaging says in a statement. Individual decisions about its use should balance the expected clinical benefits against the potential cumulative risks of recurrent...

Nuclear medicine procedure is still the best predictor of event-free survival, according to article in The Journal of Nuclear Medicine In a study comparing the ability of various medical techniques to accurately determine the extent of heart disease and stratify patients according to disease severity, researchers found that myocardial perfusion testing with gated single photon emission computed tomography (gated SPECT) was a more accurate predictor of prognosis in chronic ischemic heart...

 Patients who undergo numerous CT scans over their lifetime may be at increased risk for cancer, according to a study published in the April issue of Radiology."We found that while most patients accrue small cumulative cancer risks, 7 percent of the patients in our study had enough recurrent CT imaging to raise their estimated cancer risk by 1 percent or more above baseline levels," said Aaron Sodickson, M.D., Ph.D., assistant director of Emergency Radiology at Brigham and Women's...
