MRI-guided catheter could upgrade stroke treatment
August 22, 2014 -- A new steerable MRI-guided catheter can navigate through blood vessels from the groin to the brain in a search for clots to destroy, according to research from the University of California, San Francisco.
Owner of sham Calif. imaging center gets 8 years
August 21, 2014 -- The owner of a bogus imaging center in California that billed Medicare for $20 million in prescriptions for antipsychotic medications -- but never performed a single medical imaging exam -- received eight years in prison from a federal judge on August 18.
Researchers dial back FDG activity to reduce PET/MRI dose
August 21, 2014 -- European researchers have set the groundwork for what they believe is a feasible way to achieve optimal image quality in PET/MRI scans: balancing lower radiotracer dose with prolonged PET image acquisition time to match the longer duration needed for MR image acquisition.
DBT plus 2D mammography improves radiologist performance
August 21, 2014 -- The clinical performance of radiologists improves when digital breast tomosynthesis (DBT) is combined with conventional 2D full-field digital mammography for breast cancer screening, according to research published in the September issue of Academic Radiology.
JAMA IM: Older high-risk patients still getting cancer screenings
August 20, 2014 -- A substantial number of patients 65 years or older with limited life expectancy still receive routine screenings for cancer, despite the fact that they are unlikely to benefit from treatment procedures, according to a study published online August 18 in JAMA Internal Medicine.
CT, MRI use declined in ED after 2007
August 20, 2014 -- After a period of rapid increase from 1993 to 2007, use of medical imaging in the emergency department (ED) declined, mostly because of decreased utilization of CT and MRI, according to a new study published this month in the American Journal of Roentgenology.
Robot-assisted remote echocardiography shows promise
August 20, 2014 -- Can an ultrasound scanner be controlled robotically by an operator thousands of miles away? It's not just a dream, according to researchers who demonstrated the feasibility of robot-assisted echocardiography in a pair of articles published recently in JACC: Cardiovascular Imaging.
MRI points to brain benefits of exercise for kids
August 20, 2014 -- Diffusion-tensor MR images have confirmed that aerobically fit children have more favorable white-matter tracts in their brains than their less fit peers, thus improving their chances for greater cognitive function.
Decade of lung CAD brings insight, but little daily use
August 19, 2014 -- Computer-aided detection (CAD) is known to boost radiologist performance in the detection of lung nodules, and radiologists certainly need the help. But despite a decade of fine-tuning and some powerful new capabilities, CAD systems haven't found a place in daily practice at most imaging facilities
Who is the better radiologist?
August 19, 2014 -- If you were a patient, which radiologist would you rather have reading CT scans: the methodical but thorough plodder who orders lots of follow-up studies or the decisive reader who occasionally misses pathology? Would your answer change if you were an administrator? Or a referring physician? Dr. Saurabh Jha explores these questions.
Software extracts ROI values on PACS viewers
August 18, 2014 -- Optical character recognition software can automatically and reliably capture region-of-interest (ROI) values from images displayed on PACS viewers, potentially yielding significant time savings for radiologists, according to research published online in Academic Radiology.
MRI histogram analysis predicts bladder tumor aggressiveness
August 15, 2014 -- Sophisticated histogram-based measurements of diffusion on MRI scans can predict bladder tumor aggressiveness noninvasively, according to a new study in Abdominal Imaging. The results could potentially help clinicians tailor therapy to individual patients, and even help predict which patients' tumors will metastasize.
Study shows combined thoracic CT use has dropped
August 14, 2014 -- Combined CT scans of the thorax -- which Medicare has been keeping an eye on -- aren't being overused after all. In fact, use of the combined scans is low and falling over time, according to a new study in the Journal of the American College of Radiology.
MRI finds 2nd cancers after breast conservation therapy
August 14, 2014 -- Women who have had breast conservation therapy have an increased risk of developing second breast cancers, and they require careful tracking. But which modality is most effective? MRI, according to a new study published in Radiology.
Interventional radiologists need to follow shielding protocols
August 13, 2014 -- Patients must be protected from unnecessary radiation exposure, but what about radiologists who perform interventional exams, particularly CT-guided procedures? German researchers found that radiologists have a low risk of overexposure -- if appropriate precautions are taken.
