CT evidence of acute ischemia either alone or in combination with chronic ischemia or microangiopathy present within 24 hours of a nondisabling stroke can help predict risk of recurrent stroke for up to 90 days, researchers reported. Patients with transient ischemic attacks (TIA) or nondisabling strokes who showed evidence of acute and chronic ischemia and microangiopathy had an eight-fold increase in risk for having another stroke over the next 3 months, lead researcher Jason K. Wasserman, MD, PhD, of Ottawa Hospital Health Research Institute, Ontario, and colleagues wrote in the American Heart Association journal Stroke, published online Dec. 4.
ImageWisely.org has launched a new initiative that will help radiology providers deliver quality patient care and optimize radiation dose and image quality during fluoroscopic procedures. The organization now offers online educational materials for fluoroscopy, computed tomography and nuclear medicine exams.
Lung cancer is often called a “silent killer,” and one-fourth of people with the disease show no symptoms when they are diagnosed. It’s often caught during chest X-rays or scans performed for other reasons. Last year, the U.S. Preventive Services Task Force recommended annual CT scans for patients ages 55 to 74 with a smoking history equivalent to one pack a day for 30 years who still smoke or who have quit within 15 years.
A new study suggests that radiologists are more attentive during interpretation with the presence of dense breast tissue regions. “If we wish to optimize viewing algorithms or design appropriate training strategies, the impact of breast density on radiologists’ behaviors needs to be better understood,” wrote Al Mousa and the research team.
According to a new study published in the Annals of Internal Medicine, researchers concluded that overuse of cardiac stress testing with images has led to rising healthcare costs and unnecessary exposure to radiation. Cardiac stress testing with imaging has been the focus of debate in regards to rising healthcare costs and patient safety, and this report is believed to be the first comprehensive study of cardiac stress testing with imaging.
According to a clinical study conducted at 15 medical centers, and published in the New England Journal of Medicine, CT scans are no better than the less-often-used utltrasound exams when diagnosing kidney stones. Unlike ultrasound, CT exposes patients to significant amounts of radiation. While CT is a preferred choice in the emergency room, the ultrasound is a better place to start the initial diagnostic imaging test.

It can be hard to know when a headache should prompt medical evaluation. Rules have been developed helping medical professionals determine when imaging will be most beneficial. if a headache has other symptoms associated with it (such as nausea or vomiting) or is new, significantly worse or comes on suddenly, medical evaluation is warranted and imaging may be needed.
The medical imaging technology industry supports an estimated 12,124 jobs in the state of Washington and generates approximately $3.1 billion in total economic activity according to a report commissioned by the Medical Imaging & Technology Alliance. This activity creates an additional 5,169 jobs elsewhere in the U.S.
It can take several months to measure how effective treatment is for Cystic Fibrosis, the early-fatal lung disease, but now a new imaging method allows live viewing to monitor treatment. “Because we will be able to see how effectively treatments are working straight away, we’ll be able to develop new treatments a lot more quickly, and help better treat people with cystic fibrosis,” said lead researcher, Dr Morgan.
