The Digital Medical Imaging of Center for Diagnostic Imaging in Miami announces lung screenings for smokers and ex-smokers to help save lives. Miami, FL (PRWEB) January 27, 2014 85 percent of lung cancers occur in smokers resulting in approximately 160,000 deaths a year. Many of those deaths as a result of the disease going undetected for months, giving the disease time to spread throughout a patient's lungs until it reaches fatal stages. Both scientists and medical experts agree,...

Cerebral aneurysms of all sizes—even small ones below seven millimeters—are 12 times more likely to rupture if they are growing in size, according to a new study published online in the journal Radiology. A cerebral aneurysm is a balloon-like bulge in a weakened blood vessel in the brain. If an aneurysm ruptures, blood is leaked into or around the brain, which can cause brain damage or death. According to The Brain Aneurysm Foundation, an estimated 6...

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...

(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...

A new study from UCLA shows how magnetic resonance angiography (MRA) and computed tomography angiography (CTA) are equivalent in delineating anatomy in living renal donors. In a study that examined 30 patients and 60 kidneys, both modalities were "excellent" in detecting the number of renal arteries and veins. Dr. Mittul Gulati, lead author for the study noted, "either MRA or CTA are great tools for helping surgeons remove kidneys safely, identifying donor and recipient veins and vessels,...

(Ivanhoe Newswire) — Researchers have discovered an alternative method of detecting pulmonary embolism that is changing the game. Pulmonary embolisms occur when a blood clot — usually from the leg — travels to the lung and blocks the pulmonary artery or one of its main branches. CT angiography is the gold standard for diagnosis, but it exposes patients to ionizing radiation and iodinated contrast agent, which carries a risk of allergic reactions and kidney damage in some...

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...

The analysis of 180 CT angiography studies done using a 320 detector row CT scanner found that a contrast media protocol based on 60 milliliters of iopamidol "had sufficient enhancement in more than 96% of coronary segments," said Frank Rybicki, MD, of Brigham and Women's Hospital in Boston, and one of the authors of the study. "Many centers currently use a higher iodine load comparable or equal to 80 milliliters of iopamidol," he said. The study shows that "this is not necessary, and the...

Coronary computed tomography angiography (CTA) has excellent image quality and diagnostic confidence for the entire spectrum of pediatric patients, with significant reduction of risk with recent technological advancements, according to a study to be presented at the Sixth Annual Scientific Meeting of the Society of Cardiovascular Computed Tomography (SCCT) in Denver, July 14-17. "Traditionally, pediatric patients who require coronary artery imaging have undergone a cardiac catheterization,...
