Patients breathe easy with bile duct MRI
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.
Where Things Stand with the Radiologist Shortage
June 18th 2025A new report conveys the cumulative impact of ongoing challenges with radiologist residency positions, reimbursement, post-COVID-19 attrition rates and the aging of the population upon the persistent shortage of radiologists in the United States.
Can Contrast-Enhanced Mammography be a Viable Screening Alternative to Breast MRI?
June 17th 2025While the addition of contrast-enhanced mammography (CEM) to digital breast tomosynthesis (DBT) led to over a 13 percent increase in false positive cases, researchers also noted over double the cancer yield per 1,000 women in comparison to DBT alone.
