Effect of the Motion Correction Technique on Image Quality at 320-Detector Computed Tomography Coronary Angiography in Patients With Atrial Fibrillation.
Adaptive motion correction (AMC) is a new technique that can suppress blurring of the coronary arteries. We evaluated its effect on the image quality of coronary computed tomography angiography in patients with atrial fibrillation (AF). ⋯ Adaptive motion correction reduced motion artifacts and improved image quality of the right coronary artery in some patients with AF.

A Prototype Hybrid Gypsum-Based 3-Dimensional Printed Training Model for Computed Tomography-Guided Spinal Pain Management.
This article details design methodology of an anatomically realistic and accurate physical 3-dimensional model of the lumbosacral spine from computed tomography data utilizing 3-dimensional printing. This model is unique in that the radiodense bony lumbosacrum is reconstructed using gypsum, which because of its high calcium content allows for the appropriate imaging characteristics mimicking bone. The model allows trainees to become competent in needle placement for image-guided diagnostic and therapeutic procedures.
