AI powers liver volumetry on contrast-enhanced MRI
January 18, 2018 -- Artificial intelligence (AI) can accurately segment the liver on contrast-enhanced MRI examinations, potentially yielding significant time savings for radiologists without affecting the accuracy of volumetry results, according to researchers from the University Hospital Regensburg in Germany.  Discuss
Can artificial intelligence enable a 10-minute MRI scan?
January 17, 2018 -- Artificial intelligence (AI) algorithms promise to improve the imaging workflow, leading to significantly faster MR image acquisition times as well as vastly improved image quality in low-dose CT images. Consultant radiologist Dr. Hugh Harvey from London investigates in a new column.  Discuss
Man ruptures throat by stopping a sneeze
January 17, 2018 -- A CT scan confirmed that a man experienced a spontaneous perforation of his pharynx after attempting to stop a forceful sneeze, according to a new case report published online in BMJ Case Reports on 15 January.
3D printing technique lowers cost of modeling stenosis
January 16, 2018 -- Radiologists can plan and simulate vascular procedures on patient-specific and cost-effective 3D-printed stenosis models by using a new technique developed in Basel, Switzerland. Researchers generated stenotic vessel replicas at a more affordable price than what's currently available.  Discuss
3D-printed structures can help regenerate tissue
January 15, 2018 -- Researchers from a top London facility have developed a 3D printing technique to produce structures that mimic the properties of the softest tissues in the body. These structures may serve as templates for tissue regeneration, according to a study published in Scientific Reports.  Discuss
Minimize gadolinium dose in hereditary tumor patients
January 15, 2018 -- Gadolinium accumulation occurs in most patients undergoing contrast MRI screening after more than five MRI scans, so Belgian researchers have advocated a screening protocol for individuals with hereditary tumor syndromes that minimizes the gadolinium dose.  Discuss
3D volumetry shows promise in lung but requires care
January 12, 2018 -- Volumetry measurement of lung nodules is gaining clinical acceptance but still poses significant practical difficulties, and major factors of variability are related to the nodule, technical scanner parameters, and hemodynamic issues, according to U.K. researchers.  Discuss
Danish study lauds breast screening, rebuts controversy
January 11, 2018 -- A new Danish study shows breast cancer screening in the country performs well, with a sensitivity of more than 70% and a specificity of nearly 98%. The researchers also refute claims from other studies that question whether pilot screening programs reduced breast cancer mortality and only led to overdiagnosis.  Discuss
3D-printed breast biopsy device boosts accuracy
January 11, 2018 -- Researchers from the Netherlands have developed a 3D-printed robot-guided device capable of facilitating MR-guided breast biopsy and improving the accuracy of breast cancer diagnosis. Biopsies can even be performed inside the MRI scanner.  Discuss
DBT, synthetic 2D mammography beat standard screening
January 10, 2018 -- Single-reading digital breast tomosynthesis (DBT) plus synthesized 2D mammography increased cancer detection and decreased recalls compared with double-reading standard mammography in a new study, published online by European Radiology on 2 January. In addition, standard mammography did not improve results when added to DBT.  Discuss
