Protocol tweaks reduce radiation dose for pediatric DSA
February 26, 2015 -- In a session on Sunday at the Society of Interventional Radiology conference in Atlanta, researchers from Cincinnati Children's Hospital Medical Center will demonstrate protocols they developed that dramatically cut radiation dose for pediatric digital subtraction angiography (DSA) procedures.
ESR, ACR teleradiology white papers put patient first
February 26, 2015 -- The teleradiology white papers of the European Society of Radiology (ESR) and American College of Radiology (ACR) differ in some respects, but they both stress the importance of always keeping the patient's needs first and foremost.
Vertebral CAD aces detection of compression fractures
February 26, 2015 -- A new computer-aided detection (CAD) scheme can robustly detect vertebral compression fractures on spine CT images. The algorithm was developed by a team led by Dr. Ronald Summers, PhD, from the U.S. National Institutes of Health.
To radiology and beyond: Pixar chief mulls the patient experience
February 25, 2015 -- What does renowned animation studio Pixar have to do with medical imaging? The parallels abound, according to Ed Catmull, PhD, president of Pixar and Disney Animation Studios, who offered his perspective on how radiology can improve the patient experience in a February 20 article in the Journal of the American College of Radiology.
Radiology IT downtimes are common, but not usually serious
February 25, 2015 -- Interruptions to radiology department workflow due to IT network downtimes are common, but most are easily fixable, according to a new study published online in the Journal of the American College of Radiology. The findings are good news for radiology practices trying to integrate different IT systems into a unified reading environment.
fMRI shows different brain activity in curious preteens
February 24, 2015 -- Understanding the daily actions of preteens is a daunting task in general, but researchers from the University of California, San Francisco have had early success in using functional MRI (fMRI) to investigate why some might explore more than others.
Ultrasound + lab tests can reliably spot pediatric appendicitis
February 24, 2015 -- Combining blood tests with sonography findings significantly outperformed ultrasound alone for diagnosing or ruling out pediatric appendicitis, and the combination could also reduce the number of CT scans in children, according to research published online in the Journal of the American College of Surgeons.
3 golden rules for creating all-star radiology residents
February 23, 2015 -- Spending a good chunk of his professional life in teaching has helped Dr. Amr Ajlan of King Abdulaziz University Hospital in Jeddah, Saudi Arabia, observe what can turn a good radiology resident into an exceptional one. What he's learned from these observations is that the complexity of forming a solid radiology resident can be simplified with three primary rules.
Applying CAD twice to DBT improves performance at lower dose
February 23, 2015 -- Researchers from the University of Michigan have developed a new double-barreled approach to computer-aided detection (CAD) that uses two separate CAD algorithms on digital breast tomosynthesis (DBT) exams. They believe the technique enables a high level of sensitivity with lower radiation dose.
Multiple FDG-PET/CT scans can influence lung cancer treatment
February 20, 2015 -- By showing how four or more follow-up FDG-PET/CT scans for lung cancer can alter patient treatment plans, researchers at Johns Hopkins University are making the case for expanded Medicare reimbursement for these exams in a new article in the February edition of the Journal of Nuclear Medicine.
CT scanner in the ED cuts patient waiting times
February 20, 2015 -- Substantial time can be saved by siting CT scanners in the emergency department (ED) rather than transporting patients to the radiology department hundreds of meters away, according to a new study in the Journal of the American College of Radiology.
FDA issues massive recall of GE MRI scanners
February 19, 2015 -- The U.S. Food and Drug Administration has ordered a recall of thousands of MRI scanners manufactured by GE Healthcare to correct a problem that could "result in life-threatening injuries" if magnet shutdown modules are disconnected, according to an FDA notice.
Info on 'overdiagnosis' saps interest in breast screening
February 19, 2015 -- Giving women more information about the negative aspects of mammography, such as overdiagnosis, makes them less inclined to want breast screening, according to a new Australian study published online February 17 in the Lancet.
Breast MR useful for assessing BI-RADS 4 lesions
February 19, 2015 -- A new study published in the February issue of Radiology found that breast MR is useful for working up suspicious lesions classified as BI-RADS 4 at mammography or ultrasound -- and, in fact, can help avoid 92% of unnecessary biopsies.
Results of European CT screening trial can be widely applied
February 19, 2015 -- Individuals scanned with CT in the Nederlands-Leuvens Longkanker Screenings Onderzoek (NELSON) lung cancer screening trial had a similar risk of cancer as people who did not participate in the study, meaning the research can be generalized to a wider population.
