Two-dimensional and Doppler echocardiography reliably predict severe pulmonary regurgitation as quantified by cardiac magnetic resonance.

Background: The grading of pulmonary regurgitation (PR) severity by two-dimensional (2D) and Doppler echocardiography is not standardized. Cardiovascular magnetic resonance imaging is the clinical gold standard for PR quantification. The purpose of this study was to determine the best 2D and Doppler echocardiographic predictors of severe PR.

MR angiography of lower extremities at 3 T: presurgical planning of fibular free flap transfer for facial reconstruction.

Objective: The purpose of our study was to evaluate the use of preoperative MR angiography of the lower extremities at 3 T in candidates for fibular free flap harvesting, identifying atherosclerotic occlusive disease and congenital anomalies in this population. Our intention was to document the influence of the imaging findings on the surgical approach used.

Materials And Methods: Twenty-nine consecutive adult patients with facial abnormalities necessitating mandibular resection with subsequent osteocutaneous mandibular reconstruction who underwent preoperative MR angiography at 3 T were retrospectively reviewed.
