New MRI Brain Lesions as Surrogate Outcome for Carotid Stenting With and Without Cerebral Protection To the Editor: We read with great interest the article by Kastrup et al.1 The authors showed that the proportion of patients with any new ipsilateral diffusion-weighted imaging (DWI) lesion (49% versus 67%; P 0.05) as well as the number of new ipsilateral DWI lesions were significantly lower aft...

BACKGROUND White matter hyperintensities (WMH) are a common finding in aged individuals affected by carotid artery disease and are a risk factor for first-ever and recurrent stroke. We investigated if white matter damage increases the risk of brain microembolism during carotid artery stenting (CAS), as evaluated by the appearance of new areas of restricted diffusion on diffusion-weighted images...

PURPOSE To evaluate diffusion-weighted MR imaging (DWI-MRI) for the detection and assessment of infectious renal disease. MATERIALS AND METHODS Twenty-one patients with suspicious increased signal intensity of the kidneys on DWI sequences and corresponding ADC decrease were identified. Sixty patients without clinical signs of renal infection served as a control group. All patients were examin...

PURPOSE The purpose of this study was to evaluate the accuracy of diffusion-weighted imaging (DWI) and dynamic contrast-enhanced (DCE) perfusion MR imaging for distinguishing tumor recurrence from post-treatment effect as alternatives to dynamic-susceptibility contrast-enhanced (DSC) perfusion MR imaging when the DSC image is uninterpretable. MATERIALS AND METHODS This retrospective study was...

BACKGROUND The objective of this study was to perform a systematic review and a meta-analysis in order to estimate the diagnostic accuracy of diffusion weighted imaging (DWI) in the preoperative assessment of deep myometrial invasion in patients with endometrial carcinoma. METHODS Studies evaluating DWI for the detection of deep myometrial invasion in patients with endometrial carcinoma were ...

BACKGROUND AND PURPOSE Few data exist on the relationship between differential subpopulations of peripheral leukocytes and early cerebral infarct size in ischemic stroke. Using diffusion-weighted MR imaging (DWI), we assessed the relationship of early total and differential peripheral leukocyte counts and volume of ischemic tissue in acute stroke. METHODS All included patents had laboratory i...

BACKGROUND AND PURPOSE Metastasis to the skull is clinically important, but routine MR imaging offers moderate sensitivity for skull-metastasis detection in our experience. We sought to determine if diffusion-weighted MR imaging (DWI) could improve the detection of skull metastasis in patients with primary carcinomas that metastasized to bone compared with conventional MR imaging. MATERIALS A...

BACKGROUND AND PURPOSE Thrombolytic therapy is not recommended in patients with CT changes of recent major infarction, which has been defined as reduced attenuation or cerebral edema involving >33% of the middle cerebral artery territory (European Cooperative Acute Stroke Study [ECASS] criteria). Diffusion-weighted imaging (DWI) is more sensitive than CT in detecting acute ischemia, and the com...
