Free-breathing 3D MR sequences using the prospective acquisition correction with navigator echoes (PACE) technique can successfully image patients with biliary and/or pancreatic diseases, according to a study presented at the 2004 RSNA meeting.
Free-breathing 3D MR sequences using the prospective acquisition correction with navigator echoes (PACE) technique can successfully image patients with biliary and/or pancreatic diseases, according to a study presented at the 2004 RSNA meeting.
Dr. Eric de Kerviler and colleagues at St. Louis University Hospital compared traditional breath-hold MR cholangiography techniques-the half-Fourier acquired single-shot turbo spin-echo and rapid acquisition with relaxation enhancement sequences-with 3D turbo spin-echo MR sequences using the PACE technique.
The 3D free-breathing sequence illustrated distal bile ducts and pancreatic ducts better than both breath-hold sequences. The 3D technique, however, takes longer to perform, as a repeated sequence in the orthogonal plane is needed for coverage of the entire biliary tree and main pancreatic duct.
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.
