New acquisition method promises speedier MR
Faster scans and better image quality may result from a technique developed by researchers at the University of Wisconsin in Madison. Rather than using the conventional approach, which sweeps horizontally to gather MR data, the UW technique acquires the body’s signals radially.
Faster scans and better image quality may result from a technique developed by researchers at the University of Wisconsin in Madison. Rather than using the conventional approach, which sweeps horizontally to gather MR data, the UW technique acquires the body's signals radially.
"We can essentially acquire data during the whole scan," said Walter Bock, an associate professor of biomedical engineering and medical physics, who developed the technique. "In a conventional case, a lot of time is spent either prepping or returning to the steady state so that you can do the next acquisition. What we're doing now is a study that you can visualize in any plane in about the same time as people are doing one plane."
Block's technique achieves an advantage, he said, by exploiting the difference in resonant frequencies between fat and water, maximizing each component of the image, so that any aspect can be visualized.
The technique, which has been patented through the Wisconsin Alumni Research Foundation, also will make it easier to image other parts of the body, particularly those in which motion is a factor, such as the heart or abdomen.
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.
SNMMI: Botox May Facilitate Relief from Dry Mouth Side Effect of PSMA-Targeted Radiopharmaceuticals
June 25th 2025For patients being treated with radiopharmaceutical agents for metastatic prostate cancer, the combination of botulinum toxin and an anti-nausea patch led to a 30 percent reduction in PSMA uptake in the salivary glands, according to preliminary research findings presented at the SNMMI conference.
SNMMI: Can 18F-Fluciclovine PET/CT Bolster Detection of PCa Recurrence in the Prostate Bed?
June 24th 2025In an ongoing prospective study of patients with biochemical recurrence of PCa and an initial negative PSMA PET/CT, preliminary findings revealed positive 18F-fluciclovine PET/CT scans in over 54 percent of the cohort, according to a recent poster presentation at the SNMMI conference.
