Background Recently, high-field 7T MR imaging was introduced. The higher field-strength has potential advantages, mainly related to increased signal-to-noise-ratio. One of the potentially exciting applications may be cardiovascular MR imaging. Cardiovascular MRI requires robust correction for heart motion, breathing motion and correction of field inhomogeneities. Therefore, cardiovascular imagi...

BACKGROUND AND PURPOSE Little is known about the different patterns of fetal cerebral ischemic lesions at MR imaging. Our purpose was to evaluate the contribution of MR imaging in the evaluation of such lesions by correlating the results with ultrasonography (US) and neurofetopathologic (NFP) findings. METHODS We examined 28 fetuses (mean, 28 weeks' gestation) with cerebral ischemic lesions o...

OBJECTIVE To evaluate the usefulness of MR imaging for diseases of the small intestine, emphasizing a comparison with CT. MATERIALS AND METHODS Thirty-four patients who underwent both CT and MR imaging using FLASH 2D and HASTE sequences were analyzed. All patients had various small bowel diseases with variable association of peritoneal lesions. We compared the detectabilities of CT and MR ima...

PURPOSE The role of MR imaging in grading medial collateral ligament (MCL) injury of the knee in comparison to other grading methods (clinical findings and instrumental measurement) is hardly documented in the literature. The purpose of this study is to compare the results of MR imaging in grading acute MCL injuries to the results of a clinical grading by an instrumented valgus-varus laxity tes...

PURPOSE To evaluate the relative involvement of tibial stress injuries using high-resolution axial MR imaging and the correlation with MR and radiographic images. METHODS A total of 33 patients with exercise-induced tibial pain were evaluated. All patients underwent radiograph and high-resolution axial MR imaging. Radiographs were taken at initial presentation and 4 weeks later. High-resoluti...

We report a patient with acute hemorrhagic leukoencephalitis with a focus on serial MR imaging findings. Initial MR imaging of a 42-year-old woman revealed a 2.5-cm focal nonhemorrhagic lesion in the left thalamus and internal capsule. Twenty-four days later, fever and altered consciousness developed, and MR imaging showed huge masslike lesions in both frontal lobes, mainly involving the white ...

we report a patient diagnosed with whipple's disease (wd) who presented only with neurological symptoms. neuroimaging (mri) showed lesions with marked mass effect similar to infiltrative tumors, which were hypersignal on long tr and hyposignal on short tr images, located in several areas of the brain. in serial controls, lesions resolved with gliosis and atrophic changes as well as migration of...

There are several magnetic resonance (MR) imaging techniques that benefit from high-field MR imaging. This article describes a range of novel techniques that are currently being used clinically or will be used in the future for clinical purposes as they gain popularity. These techniques include functional MR imaging, diffusion tensor imaging, cortical thickness assessment, arterial spin labelin...
