Siemens Medical Systems of Iselin, NJ, has received Food and Drug Administration 510(k) clearancefor an upgrade package that brings faster echo-planar imagingrise times to its 1.5-tesla Magnetom Vision MRI scanner. The packagewill be available as a free upgrade to Vision scanners in thefield. It improves EPI rise times to 600 microseconds, comparedto 1200 microseconds on Vision's previous echo-planar sequence,which began shipping in November, according to Michael Sweitzer,product manager for MRI.
Rise times are the speed at which a scanner's gradients risefrom zero to maximum amplitude, which in Vision's case is fromzero to 25 mtesla/meter. Faster rise times help avoid respiratoryand blood-flow artifacts and are expected to improve Vision'sutility in future applications such as diffusion-perfusion imagingand functional imaging. Siemens is working on a hardware upgradeto Vision that will bring rise times down to 300 microseconds,Sweitzer said.
Study Shows No Impact of Hormone Therapy on PET/CT with 18F-Piflufolastat in PCa Imaging
May 7th 2025For patients with recurrent or metastatic prostate cancer, new research findings showed no significant difference in the sensitivity of 18F-piflufolastat PET/CT between patients on concurrent hormone therapy and those without hormone therapy.
