The introduction of multidetector row computed tomographic pulmonary angiography (CTPA) was associated with an apparent increase in the diagnosis of pulmonary embolism (PE), but with only minimal changes in mortality (death), suggesting the possibility of overdiagnosis, according to a report in the May 9 issue of Archives of Internal Medicine, one of the JAMA/Archives journals. This article is part of the Less Is More series in the journal.Pulmonary embolism usually occurs when a blood clot...

Researchers from Boston University School of Medicine (BUSM) have found that computed tomography pulmonary angiography (CTPA), meant to improve detection of life-threatening pulmonary embolisms (PE), has led to over-diagnosis and over treatment of this condition. These findings, which appear in May 9 issue of the Archives of Internal Medicine. may continue to grow worse as the as the use of CT scans continue to rise.The introduction in 1998 of multi-detector row CTPA revolutionized the way...

According to a new study published in Pediatrics, observing kids after a head injury may help doctors determine if they need a head x-ray. Researchers are still unsure whether too many of those x-rays, called computed topography, or CT scans, might trigger cancer later on in life. Dr. Lise Nigrovic of Children's Hospital Boston, who worked on the study, said CT scans are a good strategy for kids who have some risk of a serious brain injury, but have not started showing symptoms.  "CT isn't...

The use of breast shields is the technique of choice to protect the breasts of women from radiation exposure while undergoing chest CT examinations, according to a new study.The use of CT has grown exponentially which brings into question the level of radiation exposure to patients. Recently the International Commission of Radiation Protection (ICRP) increased the tissue weighting factor for the breast from 0.05 to 0.1 noting that breast tissue is even more sensitive to radiation exposure...

Two students will become the first to graduate with a Bachelor of Science in Radiologic Sciences degree. Mesa, AZ (PRWEB) May 02, 2011 Two of the 10 students in Pima Medical Institute's first Bachelor of Science in Radiologic Sciences (BSRS) online class will be celebrating their graduation Friday. After nearly 15 months working to complete the program, Lisa Ramos and David Jones are the first graduates to formally accept their degree. Each graduate was invited to choose the graduation...

A recent study shows that pelvic imaging using computed tomography (CT) examinations are not necessary for diagnosing patients with venous thromboembolism (VTE) and eliminating this exam can significantly reduce a patient's exposure to excessive radiation dose.CT venography of the pelvis during CT pulmonary angiography does not improve the detection of VTE, says Dr. Charbel Ishak, lead author for this study. He asserts, "Using CT venography in the lower extremities without including the...

MADISON HEIGHTS, Mich., May 2, 2011 /PRNewswire/ -- City Medical, P.C., the principal provider of high-quality, community-focused health care for Madison Heights and Southgate, Michigan, today announced that it has added a new digital X-ray machine at its Madison Heights office . The new Agfa-Viztek Opal-RAD CR Digital System is a state-of-the-art, X-ray machine that allows for digital images to be captured instantly, displayed within seconds and if necessary, sent immediately to...

3D models, produced by combining a patient's CT scans and 3D printing technology are proving useful in neurosurgical planning.3D printing technology is a fast and affordable way to build 3D models for neurosurgical planning. Radiologists are able to transform ultra high-resolution CT patient images into 3D solid models using a 3D color printer commonly used in architecture, engineering and construction.An advantage of 3-D models is that they identify defects that 2-D images do not, which...

The idea of probing the body's interior with radiation stretches back to experiments with X rays in the 1800s, but more than a century later, images taken with radiological scans still are not considered reliable enough to, for example, serve as the sole indicator of the efficacy of a cancer treatment. Lisa Karam, a biochemist at the National Institute of Standards and Technology (NIST) and a few dozen of her colleagues across North America have set out to change that.The group of radiology...
