256-slice CT proves its might in stroke imaging
A prototype 256-slice CT unit can perform rapid whole-brain perfusion imaging in stroke patients and may one day compete head to toe with other modalities.
A prototype 256-slice CT unit can perform rapid whole-brain perfusion imaging in stroke patients and may one day compete head to toe with other modalities.
The system, developed by Toshiba, has a wide detector that allows brain imaging in a single rotation at a low radiation dose. Clinical trials are complete, and a commercial system should hit the market by summer 2008, according to Dr. Kazuhiro Katada, a professor of radiology at Fujita Health University in Toyoake. He showed data from 11 stroke patients who underwent 50-second scanning at 80 kV and 80 mA. The 256-slice images offered better visualization of superior parietal lobe lesions and remote effects when compared with conventional CT perfusion. Katada spoke at the 2007 Stanford Multidetector-Row CT Symposium.
Study Reaffirms Low Risk for csPCa with Biopsy Omission After Negative Prostate MRI
December 19th 2024In a new study involving nearly 600 biopsy-naïve men, researchers found that only 4 percent of those with negative prostate MRI had clinically significant prostate cancer after three years of active monitoring.
Study Examines Impact of Deep Learning on Fast MRI Protocols for Knee Pain
December 17th 2024Ten-minute and five-minute knee MRI exams with compressed sequences facilitated by deep learning offered nearly equivalent sensitivity and specificity as an 18-minute conventional MRI knee exam, according to research presented recently at the RSNA conference.
Can Radiomics Bolster Low-Dose CT Prognostic Assessment for High-Risk Lung Adenocarcinoma?
December 16th 2024A CT-based radiomic model offered over 10 percent higher specificity and positive predictive value for high-risk lung adenocarcinoma in comparison to a radiographic model, according to external validation testing in a recent study.
