Developed by radiologist Dr. Taro Takahara and colleagues at Tokai University School of Medicine in Japan, diffusion-weighted whole-body MR imaging with background body signal suppression (DWIBS) paves the way for practical whole-body 3D MR diffusion imaging. A new STIR-EPI sequence, performed with SENSE parallel processing, permits long acquisition times during free breathing to boost contrast resolution and overcome fat saturation problems.

Gray scale was reversed, black for white, producing a rotating 3D maximum intensity projection that resembled volumetric displays now generated with FDG-PET. The mechanism for producing DWI contrast in metastatic disease is not clearly understood but is thought to be associated with large cell sizes and high cellular densities that are common in cancerous tissue. Takahara described the approach at the International Society for Magnetic Resonance in Medicine meeting.
FDA Clears Virtually Helium-Free 1.5T MRI System from Siemens Healthineers
June 26th 2025Offering a cost- and resource-saving DryCool magnet technology, the Magnetom Flow.Ace MRI system reportedly requires 0.7 liters of liquid helium for cooling over the lifetime of the device in contrast to over 1,000 liters commonly utilized with conventional MRI platforms.
