OBJECTIVE. We report the development and use of MRI-compatible and MRI-visible 3D printed models in conjunction with advanced visualization software models to plan and simulate safe access routes to achieve a theoretic zone of cryoablation for percutaneous image-guided treatment of a C7 pedicle osteoid osteoma and an L1 lamina osteoblastoma. Both models altered procedural planning and patient care.

OBJECTIVE. The objective of our study was to reduce variation in image quality of orthogonal reformatted images generated from long–z-axis CT angiography (CTA) studies of the upper and lower extremities.

AMERICAN JOURNAL OF ROENTGENOLOGY. Prospective Comparison of Reduced-Iodine-Dose Virtual Monochromatic Imaging Dataset From Dual-Energy CT Angiography With Standard-Iodine-Dose Single-Energy CT Angiography for Abdominal Aortic Aneurysm

Mukta D. Agrawal, George R. Oliveira, Sanjeeva P. Kalva, Daniella F. Pinho, Ronald S. Arellano and Dushyant V. Sahani

OBJECTIVE. The purpose of this study was to compare the image quality of reduced-iodine-dose single-source dual-energy CT angiography (CTA) with that of standard-iodine-dose single-energy CTA in examinations of patients with abdominal aortic aneurysm and to assess the effect of the concentration of iodinated contrast medium on intravascular enhancement and image quality of reduced-iodine-dose CTA.
