Femur irregularities on MRI are usually benign
June 16, 2020 -- Swiss researchers have found that although routine knee MRI scans of adolescents often show incidental irregularities in the distal femur bone that may be confused with more serious conditions, these are typically benign and can be tracked as such, according to a study published June 16 in Radiology.  Discuss
MR-HIFU techniques may improve Parkinson's treatment
June 16, 2020 -- Three new techniques for MRI-guided high-intensity focused ultrasound (HIFU) can more exactly target an area in the brain linked to Parkinson's disease and essential tremor and allow for more precise treatment of these conditions, according to a review published June 14 in Brain.  Discuss
3D image analysis spots cartilage changes on knee MRI
June 16, 2020 -- A 3D image-analysis software algorithm can identify small changes in the cartilage of knee joints over time on MRI exams, potentially paving the way for development of new osteoarthritis treatments, according to a study published May 24 in the Journal of Magnetic Resonance Imaging.  Discuss
COVID-19: Early signs of recovery, but uncertainty ahead
June 15, 2020 -- The global pandemic has created an unprecedented shock to the medical imaging and healthcare sectors. What is the future likely to hold? What are the key economic trends, bright spots, and areas of greatest risk? Market columnist Steve Holloway investigates.  Discuss
Breast MRI lesion score can cut unnecessary biopsies
June 15, 2020 -- A lesion classification scheme named after breast MRI pioneer Dr. Werner Kaiser may help prevent anywhere from 45% to 72.5% of unnecessary breast biopsies in high-risk patients, Austrian researchers have found. The tool also refutes the notion of benign-appearing cancers.  Discuss
Deep learning detects HCC on contrast-enhanced MRI
June 12, 2020 -- A deep-learning algorithm can detect hepatocellular carcinoma (HCC) on contrast-enhanced liver MRI exams within seconds and at an accuracy level comparable to a less-experienced radiologist, according to a preliminary study published online June 11 in Scientific Reports.  Discuss
MRI tracks brain damage caused by COVID-19
June 12, 2020 -- Hospitalized patients with COVID-19 should undergo an MRI exam before being discharged to determine whether they have sustained brain damage from the virus, according to researchers from Johns Hopkins University who published a study June 10 in the Journal of Alzheimer's Disease.  Discuss
New DWI-MRI protocol looks promising for breast imaging
June 8, 2020 -- A promising new protocol for diffusion-weighted MRI (DWI-MRI) resulted in better image quality and improved signal-to-noise ratio for breast lesions in a prospective study published online on May 29 in Radiology: Imaging Cancer.  Discuss
Contrast MRI helps radiologists identify ectopic pregnancy
June 8, 2020 -- Contrast-enhanced MRI can help less experienced radiologists identify implantation sites of ectopic pregnancy, according to a study published in the July issue of Clinical Radiology.  Discuss
Functional, diffusion MRI could benefit from AI
June 8, 2020 -- For a variety of reasons, functional and diffusion MRI haven't been particularly hot research areas for artificial intelligence (AI). But these advanced imaging modalities do offer a ripe opportunity, according to a presentation at the virtual 2020 American Society of Neuroradiology meeting.  Discuss
