Could a metabolic test revamp CT lung cancer screening?
July 18, 2019 -- A low-cost metabolic test that uses MR spectroscopy to analyze blood and tissue samples may complement the early detection of lung cancer and help clinicians identify individuals who would benefit most from CT lung screening, according to an article published online July 16 in Scientific Reports.  Discuss
PET, MRI show physical activity aids brain health
July 17, 2019 -- PET and MR images show that older adults who are physically active have significantly less beta-amyloid accumulation and gray matter volume loss, which results in more stable cognitive skills, according to a study published online July 16 in JAMA Neurology.  Discuss
Portable scanner could boost point-of-care brain MRI
July 17, 2019 -- The ability to perform a whole-brain MRI scan at the point of care for patients with mobility challenges could soon become a reality with a portable, lightweight device now under development by researchers at the Massachusetts Institute of Technology in Cambridge, MA.  Discuss
Preop breast MRI forecasts positive tumor margins
July 16, 2019 -- Preoperative breast MRI features such as multifocal disease, a nonmass enhancement lesion, and greater background parenchymal enhancement can help forecast positive or close margins at breast-conserving surgery, according to a new study published in the August issue of the European Journal of Radiology.  Discuss
MRI, age can predict return from baseball elbow injury
July 16, 2019 -- Patient age and findings on MRI can be helpful in determining how soon baseball players might return to action after an elbow injury, according to research presented at the recent American Orthopaedic Society for Sports Medicine annual meeting in Boston.  Discuss
Low-field MRI ensures safe scans with implanted devices
July 12, 2019 -- How low can clinicians go with MRI magnet strength to ensure the safety of patients with implanted cardiac rhythm management devices and maintain diagnostic-quality images? The answer is 0.2 tesla, according to an Austrian study published July 4 in the European Journal of Radiology.  Discuss
GBCA-enhanced MRI does not influence MS progression
July 11, 2019 -- Researchers found evidence of gadolinium accumulation in the brains of multiple sclerosis (MS) patients after MRI scans using a gadolinium-based contrast agent (GBCA), but the patients' conditions did not worsen by the five-year follow-up in a new study, published online July 5 in Neurology.  Discuss
Advances in imaging, AI make cardiac MRI more accessible
July 10, 2019 -- Cardiac MRI is often a last resort in imaging modalities, for reasons including difficulty of image acquisition, cost, and hardware availability. Dr. Melany B. Atkins discusses the advantages that technologies such as 4D flow and artificial intelligence (AI) bring to cardiac MRI and how their use can benefit both patients and providers.  Discuss
Cardiac MRI plan hikes myocarditis detection rate
July 9, 2019 -- Swiss and German researchers have devised an effective diagnostic cardiac MRI workup strategy that has quadrupled the rate of myocarditis detection in patients with myocardial infarction and nonobstructive coronary artery disease, according to a study published July 3 in Swiss Medical Weekly.  Discuss
Preop breast MRI improves DCIS surgical planning
July 9, 2019 -- Preoperative breast MRI improves the surgical planning and outcomes of ductal carcinoma in situ (DCIS), according to a new study published online July 5 in Academic Radiology.  Discuss
