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.  Discuss
New MR elastography method may speed up brain scans
April 19, 2019 -- 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.  Discuss
Multidirectional spectroscopy enables human neuroimaging
April 18, 2019 -- 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.  Discuss
Tips and tricks for imaging the pelvic floor
April 17, 2019 -- 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.  Discuss
AI can evaluate treatment response for brain tumors
April 5, 2019 -- An artificial intelligence (AI) algorithm can provide automated quantitative analysis of gliomas on MRI examinations, yielding more accurate assessments of how well these brain tumors are responding to treatment than current manual methods, German researchers reported in an article published online on 2 April in Lancet Oncology.  Discuss
DTI-MRI reveals alcohol damage to brain after abstinence
April 3, 2019 -- With the assistance of diffusion-tensor MR imaging (DTI-MRI), researchers from Spain and Germany have found evidence that damage to the brain's white matter continues even after men who consume copious amounts of alcohol have stopped drinking, according to a study published online on 3 April in JAMA Psychiatry.  Discuss
MRI proves value in tricky cases of cervical cancer
April 2, 2019 -- Award-winning research from Italy has underlined the clinical relevance of T2-weighted MRI as an important diagnostic tool to identify patients with parametrial invasion in the preoperative assessment of cervical cancer. The new study from Modena received many plaudits at ECR 2019 in Vienna.  Discuss
Focused ultrasound releases cancer drugs on target
March 29, 2019 -- Researchers from the U.K. are using computational planning models to determine the focused ultrasound parameters required to release drugs from liposomes, without the need for real-time thermometry. This approach could make ultrasound-mediated targeted drug delivery more widely accessible and simpler to administer than techniques that use MRI guidance.  Discuss
Strickland gives priority to modernization of RCR
March 26, 2019 -- Over the coming months, Dr. Nicola Strickland will start a thorough overhaul of the U.K. Royal College of Radiologists (RCR) modus operandi. In a video interview, she explains about her team's plan to update the charter, amend the status of overseas fellows, and adopt a new approach to training.  Discuss
Ga-68 PMSA PET/CT tops for prostate cancer recurrence
March 25, 2019 -- PET/CT with the radiopharmaceutical gallium-68 (Ga-68) prostate-specific membrane antigen (PSMA) should be the choice over whole-body-MRI for detecting prostate cancer recurrence after radical prostatectomy, a German group advocates in a study published by the European Journal of Nuclear Medicine and Molecular Imaging.  Discuss
