256-slice CT creates 4D studies
A prototype 256-slice CT scanner allowed Dr. Shinichiro Mori and a team of Japanese researchers from Chiba and Osaka to perform dynamic imaging of liver cancer in real-time in three randomly selected patients.
A prototype 256-slice CT scanner allowed Dr. Shinichiro Mori and a team of Japanese researchers from Chiba and Osaka to perform dynamic imaging of liver cancer in real-time in three randomly selected patients.
They produced 3D coronal renderings of the hepatic veins, abdominal aorta, and renal arteries in less than 40 seconds after contrast injection. The technique also allowed them to observe the backflow of contrast material to the inferior vena cava in one patient experiencing heart failure (AJR 2005;185:253-256).
The 256-slicer provided diagnostically viable cine imaging reconstructions of structures with a craniocaudal distance of approximately 10 cm in any plane with several postprocessing techniques, including full volume renderings and maximum intensity projections. The system can cover one or more organs during one phase of contrast enhancement and can also produce functional studies of the head, liver, and renal and coronary arteries.
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.
