Effect of the extracranial deep brain stimulation lead on radiofrequency heating at 9.4 Tesla (400.2 MHz).
To study the effect of the extracranial portion of a deep brain stimulation (DBS) lead on radiofrequency (RF) heating with a transmit and receive 9.4 Tesla head coil. ⋯ Development of protocols seems feasible to keep RF heating near DBS electrodes clinically safe during ultra-high field head imaging.

ReviewCommon data elements in radiologic imaging of traumatic brain injury.
Traumatic brain injury (TBI) has a poorly understood pathology. Patients suffer from a variety of physical and cognitive effects that worsen as the type of trauma worsens. ⋯ Technical details regarding state-of-the-art protocols for both MRI and CT are also presented with the hope of guiding current and future research efforts as to what is possible in the field. Stress was also placed on the potential to create a database of CDEs as a means to best record information from a given patient from the reading of the images.

Comparative StudyComparison between areas with Gd-EOB-DTPA uptake and without in hepatocellular carcinomas on Gd-EOB-DTPA-enhanced hepatobiliary-phase MR imaging: pathological correlation.
To determine histological and MR imaging differences between areas with Gd-EOB-DTPA (gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid) uptake and without in hepatocellular carcinomas (HCCs) as seen on Gd-EOB-DTPA-enhanced hepatobiliary-phase MR images. ⋯ Although macroscopically, a non-hypointense area of an HCC seen on GD-EOB-DTPA-enhanced hepatobiliary-phase images may be associated with the area with a green color, no definite microscopic and MR imaging findings that could discriminate a non-hypointense from a hypointense area of an HCC was found.

T(2)-weighted 3D fast spin echo imaging with water-fat separation in a single acquisition.
To develop a robust 3D fast spin echo (FSE) T(2)-weighted imaging method with uniform water and fat separation in a single acquisition, amenable to high-quality multiplanar reformations. ⋯ 3D-FSE-IDEAL provides volumetric T(2)-weighted images with uniform water and fat separation in a single acquisition. High-resolution images with multiple contrasts can be reformatted to any orientation from a single acquisition. This could potentially replace 2D-FSE acquisitions with and without fat suppression and in multiple planes, thus improving overall imaging efficiency.
