Portable MRI helps clarify stroke symptoms more quickly
August 25, 2021 -- Portable MRI can help clinicians quickly and accurately identify intracranial hemorrhages in patients exhibiting signs of stroke -- information that can be potentially lifesaving, according to a study published August 25 in Nature Communications. Read More

MRI shows long-term effects of concussion on young athletes
August 25, 2021 -- MRI scans show that young athletes with a history of concussion sustain more brain injury from later concussive events compared with those players with no such history, according to a study published August 25 in Neurology. Read More

Prediction models can reduce false positives in breast MRI screening
August 17, 2021 -- Prediction models based on clinical characteristics could help reduce false positives in women with dense breasts who undergo supplemental breast cancer screening with MRI, according to a study published August 17 in Radiology. Read More

Automated MR image segmentation enables AR use for surgeons
August 13, 2021 -- An automated MR image segmentation algorithm can generate 3D models of brain tumors that neurosurgeons can use for augmented reality (AR)-based viewing and surgical planning, according to research published in the Journal of Neurosurgery. Read More

New blood test for prostate cancer screening reduces unnecessary MRI
August 12, 2021 -- Swedish researchers have found that using a new type of blood test to screen for prostate cancer can reduce unnecessary MRI scans by 36% and avoid overdiagnosis, according to a study published August 12 in Lancet Oncology. Read More

Can virtual reality improve the patient experience in MRI?
August 12, 2021 -- Having patients wear virtual reality goggles during their MRI exams could go a long way toward reducing their anxiety and claustrophobia during the scans, according to a study published August 11 in Scientific Reports. Read More

Deep learning classifies brain tumors on single MRI scans
August 11, 2021 -- A deep-learning model was able to classify brain tumors as one of six common types on a single 3D MRI scan, according to a study published August 11 in Radiology: Artificial Intelligence. Read More

DCIS shows as nonmass enhancement on breast MRI
August 6, 2021 -- Ductal carcinoma in situ (DCIS) diagnosed with conventional breast imaging usually showed nonmass enhancement on breast MRI scans, with a larger median span for lesions than mammography and an increased cancer detection rate of 6.2%, in a study published August 3 in Radiology.
