Modified triexponential analysis of intravoxel incoherent motion for brain perfusion and diffusion.
To noninvasively obtain more detailed information on brain perfusion and diffusion using modified triexponential analysis. ⋯ Diffusion analysis with triexponential function enables noninvasive gathering of more detailed information on brain perfusion and diffusion.

Rates of safety incident reporting in MRI in a large academic medical center.
To describe our multiyear experience in incident reporting related to magnetic resonance imaging (MRI) in a large academic medical center. ⋯ MRI-related incident reports are relatively infrequent, occur at significantly higher rates in inpatients, and usually do not result in patient harm. Diagnostic test orders, adverse drug reactions, and medication/IV safety were the most frequent safety incidents.

Detection of pulmonary embolism with free-breathing dynamic contrast-enhanced MRI.
To evaluate the use of dynamic contrast-enhanced (DCE) magnetic resonance imaging (MRI) during free breathing for the detection of acute pulmonary embolism (PE). ⋯ Free-breathing DCE MRI may have potential use for the assessment of PE, and does not require patient cooperation in breath-holding.

Imaging of the lumbar plexus: Optimized refocusing flip angle train design for 3D TSE.
To study the effects of refocusing angle modulation with 3D turbo spin echo (TSE) on signal and sharpness of small oblique nerves embedded in muscle and suppressed fat in the lumbar plexus. ⋯ An optimized flip angle train in 3D TSE imaging of the lumbar plexus considering geometry-specific blurring effects from both the nerve and the surrounding tissue can improve the delineation of small nerves.

Characterization of breast masses as benign or malignant at 3.0T MRI with whole-lesion histogram analysis of the apparent diffusion coefficient.
To investigate the utility of whole-lesion apparent diffusion coefficient (ADC) histogram analysis in capturing breast lesion heterogeneity and determine which ADC metric may help best differentiate benign from malignant breast mass lesions at 3.0T magnetic resonance imaging (MRI). ⋯ These results suggest that whole-lesion ADC histogram analysis may facilitate the differentiation between benign and malignant breast mass lesions.
