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 -- There has been much discussion about protecting patients 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.
AHRA: Evidence-based medicine requires evidence-based management
August 12, 2014 -- As the U.S. government tries to improve the way healthcare is delivered, the talk is all about evidence-based medicine. But shifting to this framework won't help unless radiology departments are managed the same way, according to a presentation at the AHRA annual meeting in Washington, DC.
MRI tracks early brain development in newborns
August 12, 2014 -- For the first time, researchers are using MRI to calculate the volume of multiple brain regions in newborns to investigate how those areas develop based on gender, gestational period, and other factors in the first 90 days of life.
Circulation: Little radiation risk seen in cardiac scans
August 11, 2014 -- A lack of demonstrated harms combined with significant recent dose reductions have led at least one group of cardiovascular imaging specialists to worry less about the risks of a heart scan and more about the well-being of the patient, according to a new review article in Circulation.
AHRA: For patient satisfaction, focus on right-brain skills
August 11, 2014 -- As the delivery of healthcare shifts to value-based service, radiologists and their practices can't neglect patient satisfaction. To achieve service excellence, it's wise to highlight right-brain skills, according to a talk at the AHRA annual meeting in Washington, DC.
Automated CT tool reveals pulmonary hypertension
August 8, 2014 -- In a new study that used computer-aided analysis, the presence of low normal lung tissue volume correlated with pulmonary arterial hypertension at 3D CT. The technique could offer a more accessible and less invasive diagnostic test than right heart catheterization, according to researchers from Japan.
Canadian policy to improve MRI referrals has mixed results
August 7, 2014 -- A campaign by the Ontario Ministry of Health to reduce inappropriate referrals for lumbar MRI resulted in more-appropriate exams, but it did not lower the number of new referrals, according to a study published in the August issue of the Journal of the American College of Radiology.
