Dutch reveal how obesity can influence brain volume
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.
Breast MRI equally proficient at 1.5T and 3T
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.
Belgian team warns about health effects of vaping
Two senior radiologists from Belgium have issued a fresh warning about the potentially harmful effects of electronic cigarettes on health, and they have called for more research into this emerging field. Their findings are to be presented soon at the European Society of Thoracic Imaging congress in Paris.
Conebeam CT mitigates cardiac motion during imaging
Robotic C-arm conebeam CT helps guide interventional cardiac surgical procedures and can be valuable in radiotherapy, but the intrinsic motion of the beating heart causes blurring and image artifacts. A new technique can help overcome this limitation.
AI can segment white-matter hyperintensities on MRI
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.
3D-bioprinted model mimics real human heart properties
Researchers from Israel have created a 3D-printed model that captures the immunological, biochemical, cellular, and anatomical properties of a real human heart, according to an article published online on 15 April in Advanced Science.
New MR elastography method may speed up brain scans
A global team of investigators believes it is on track to cut the time of an MRI brain scan to milliseconds with an MR elastography technique. The study was published online on 17 April in Science Advances.
Multidirectional spectroscopy enables human neuroimaging
Researchers have used a multidirectional functional near-infrared spectroscopy system for human neuroimaging. Their novel approach produces a richer dataset and could improve 3D visualization of brain activity.
Can AI help radiologists detect prostate cancer?
A team of researchers from the U.S. has developed an artificial intelligence (AI) algorithm that could enable less-experienced radiologists to better detect prostate cancer on multiparametric MRI. The group reported the findings at the recent IEEE International Symposium on Biomedical Imaging in Venice, Italy.
Tips and tricks for imaging the pelvic floor
A key strength of MRI is it allows accurate anatomic and functional evaluation of the three pelvic compartments, enabling the correct identification of the compartments involved, according to award-winning Portuguese researchers. It often leads to identification of other causes of genitourinary complaints, they said.
