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.
BMJ: Mammography skeptics attack AgeX trial design
A team of British researchers known for past criticism of screening mammography is arguing that the design of the U.K.'s Age Extension Trial of Breast Cancer Screening (AgeX) is flawed. The group believes evidence from the trial should not be used to justify extending breast screening beyond existing age ranges, according to an analysis published online on 10 April in BMJ.
Late pregnancy ultrasound could reduce C-section rate
A U.K. group has found that late pregnancy ultrasound scans at 36 weeks help women avoid undiagnosed breech presentation of their babies, translating to healthier deliveries, lower rates of emergency cesarean sections (C-sections), and perhaps even lower healthcare costs, according to a study published on 16 April in PLOS Medicine.
Italians unveil new data on prolonged CT lung screening
Fresh statistics from the Multicentric Italian Lung Detection trial have underlined the increasing benefits of CT lung screening over time -- starting after the fifth year. The authors reported a 39% reduction in lung cancer mortality risk for eligible smokers at 10 years.
German team employs AR for CT-guided spine surgery
A group from Germany used augmented reality (AR) technology to overlay CT scans onto patients with spinal lesions -- lowering the radiation dose required for CT-guided surgery while maintaining high navigational accuracy, according to an article published online on 5 April in the European Spine Journal.
Ultrasound CADx software can stratify thyroid nodules
Researchers from Spain found that ultrasound computer-aided diagnosis (CADx) software could -- despite some limitations -- offer value in stratifying the malignancy risk of thyroid nodules, according to a study published on 11 April in the American Journal of Roentgenology.
DBT boosts diagnosis of additional breast cancer
French investigators have found that adding digital breast tomosynthesis (DBT) to digital mammography boosts diagnostic accuracy for finding additional ipsilateral and contralateral breast cancer in women with nondense breast tissue, according to a study published online on 9 April in the journal Radiology.
