Medical Imaging Compatibility of Magnesium- and Iron-Based Bioresorbable Flow Diverters.

Background And Purpose: Bioresorbable flow diverters are under development to mitigate complications associated with conventional flow-diverter technology. One proposed advantage is the ability to reduce metal-induced artifacts in follow-up medical imaging. In the current work, the medical imaging compatibility of magnesium- and iron-based bioresorbable flow diverters is assessed relative to an FDA-approved control in phantom models.

Automated low-contrast pattern recognition algorithm for magnetic resonance image quality assessment.

Purpose: Low contrast (LC) detectability is a common test criterion for diagnostic radiologic quality control (QC) programs. Automation of this test is desirable in order to reduce human variability and to speed up analysis. However, automation is challenging due to the complexity of the human visual perception system and the ability to create algorithms that mimic this response.

Aging and quality control of color LCDs for radiologic imaging.

Our practice has long been concerned with the effects of display quality, including color accuracy and matching among paired color displays. Three years of data have been collected on the historical behavior of color stability on our clinical displays. This has permitted an analysis of the color-aging behavior of those displays over that time.

Safety and MRI artifact evaluation at 1.5 T of metallic mounting sheath of a marking clip inadvertently deployed at stereotactic biopsy.

Objective: The purpose of our study was to assess the MRI risk factors for the patient after an unusual case of inadvertent deployment of the mounting sheath of a metallic clip used at stereotactic breast biopsy.

Materials And Methods: We evaluated the materials for ferromagnetic properties, heating, and artifacts.

Results: Our analysis showed significant deflection and prominent susceptibility artifacts of the sheath at 1.
