(Ivanhoe Newswire) — The mere thought of getting a standard colonoscopy makes some people shudder in their seats, and unfortunately, prevents many people from receiving the critically important check-up. But there is a new procedure that may make the whole process a bit easier to endure. Typically, the standard optical colonoscopy involves the examination of the internal surface of the colon using a lit fiber-optic tube with a camera at the end. The preparation is what drives people...

Contrast-enhanced ultrasound is an effective, noninvasive method for monitoring patients who undergo endovascular repair for abdominal aortic aneurysms, according to a new study published in the journal Radiology. "Our findings support the addition of contrast-enhanced ultrasound as a complementary tool in the follow-up of these patients," said Rosa Gilabert, M.D., Ph.D., from the Hospital Clinic at the University of Barcelona in Spain. An abdominal aortic aneurysm occurs when the large...

Computerized 'virtual cleansing' helps identify lesions most likely to become cancerous A CT-scan-based form of virtual colonoscopy that does not require laxative preparation appears to be as effective as standard colonoscopy in identifying the intestinal polyps most likely to become cancerous. In the May 15 issue of Annals of Internal Medicine, a Massachusetts General Hospital (MGH)-based research team reports finding that the new technique, which uses computer-aided systems both to...

(Ivanhoe Newswire) — Monitoring aneurysms with a less invasive option! Researchers are saying a simple contrast ultrasound is the answer. An abdominal aortic aneurysm occurs when the large blood vessel that supplies blood to the abdomen, pelvis and legs becomes abnormally large or balloons outward. Abdominal aortic aneurysms can occur in anyone, but are most commonly found in men over the age of 60 with one or more risk factors. The aneurysm places stress on the wall of the aorta...

(Ivanhoe Newswire) -- Respiratory movement during radiotherapy makes it difficult to hit the right treatment target and this in turn can lead to an under-dose of radiation to the tumor, or a potentially toxic over-dose to the surrounding healthy tissue. Getting this right is a real challenge for the radiotherapist, but new techniques are helping to deliver the correct dose to the right place Deep Inspiration Breath Hold (DIBH) can spare the heart when irradiating left-side breast cancer...

New FDA Draft Proposal On X-Ray Imaging For Children
2012-05-10 06:40:12

Connie K. Ho for RedOrbit.com The U.S. Food and Drug Administration (FDA) recently announced a proposal to encourage X-ray manufacturers to consider children´s safety in the development of new imaging devices. The FDA is recommending that manufacturers who create new X-ray imaging devices include protocols and instructions for use on pediatric patients. The draft proposal by the FDA also advocates that companies who cannot demonstrate safe and effective use of the X-ray imaging...

Unnecessary imaging was recommended in a significant number of studies but referring physicians often did not adhere to PET/CT report recommendations Advanced imaging has been identified as one factor that contributes to the overall rising cost of healthcare in the US. Unnecessary or inappropriate imaging utilization magnifies the cost burden associated with advanced imaging studies like MRIs and PET/CT scans. Though these studies often provide the best clinical information for making a...

Cervical spine CT examinations are unnecessary for emergency department (ED) patients who are a victim of "simple assault" or who have a "ground-level fall", unless the patient has a condition that predisposes the patient to spine fracture, a new study finds. The study, conducted at Grady Memorial Hospital by researchers from the Department of Radiology and Imaging Sciences of the Emory University School of Medicine in Atlanta, found that out of 218 exams for simple assault, there were...

(Ivanhoe Newswire) — X-rays have changed the way we look at medicine and strong technology is allowing us to make the process safer each year. A new study shows Cone beam CT is superior to mutidetector CT for detecting a small hole in the bony wall of the inner ear bone that can cause dizziness and hearing loss, and it uses half the radiation dose. The study, conducted in Bruges, Belgium, included 21 patients who had both a cone beam CT and a multidetector CT examination of their...
