U.K. issues new advice on gadolinium contrast safety
May 8, 2019 -- The U.K. Royal College of Radiologists has updated its guidance on the administration of gadolinium-based contrast agents to adult patients. The 23-page document addresses concerns about possible long-term gadolinium retention in the brain and the risk of nephrogenic systemic fibrosis. Read More
AI can help facilitate gadolinium-free cardiac MRI
May 7, 2019 -- Chinese and U.K. investigators have developed an artificial intelligence (AI) algorithm that can detect chronic myocardial infarction on noncontrast-enhanced cardiac cine MRI. This might avoid the need for gadolinium-based contrast, according to an article posted online on 30 April in Radiology. Read More
Italians use AR to bolster prostate cancer surgery
May 6, 2019 -- Italian researchers have used augmented reality (AR) technology to overlay dynamic virtual 3D models based on MRI scans directly onto patient anatomy. In a recent article in European Urology, they found their method to be highly effective for prostate cancer surgery. Read More
New breast CAD advances detection with MRI, PET
May 3, 2019 -- Researchers from Austria have developed a new computer-aided segmentation and diagnostic (CAD) algorithm to distinguish between cancerous and benign breast lesions using PET and MRI data. Their study was published online on 27 April in European Radiology Experimental. Read More
Contrast mammo equals MRI for measuring tumor size
April 30, 2019 -- Korean researchers have found that contrast-enhanced digital mammography works just as well as contrast-enhanced breast MRI for measuring breast tumors before surgery, according to a study published on 24 April in the British Journal of Radiology. Read More
Dutch reveal how obesity can influence brain volume
April 26, 2019 -- Dutch researchers investigating obesity have used MRI to link greater levels of body fat to changes in the brain's form and structure, particularly with smaller volumes of gray matter. Their study was published online on 23 April in Radiology. Read More
Breast MRI equally proficient at 1.5T and 3T
April 25, 2019 -- Talk about a win-win. Choosing either a 1.5-tesla or 3-tesla MRI scan for breast imaging will result in comparably high diagnostic accuracy, according to a study published in the May issue of the European Journal of Radiology. Read More
AI can segment white-matter hyperintensities on MRI
April 22, 2019 -- Artificial intelligence (AI) algorithms are capable of segmenting cerebral white-matter hyperintensities of presumed vascular origin on brain MR images as well as or better than human observers, enabling more reliable quantification of these lesions, according to the results of a recent AI developer challenge.
