Usefulness of diffusion‐weighted MRI with echo‐planar technique in the evaluation of cellularity in gliomas
The purpose of this study was to evaluate the utility of diffusion‐weighted magnetic resonance imaging (MRI) with echo‐planar imaging (EPI) technique in depicting the tumor cellularity and grading ofExpand

Correlation of MR imaging-determined cerebral blood volume maps with histologic and angiographic determination of vascularity of gliomas.
OBJECTIVE Our purpose was to evaluate the relationships between the ratio of maximum relative cerebral blood volume (rCBV) (rCBV ratio = rCBV[tumor]/rCBV[contralateral white matter]) and histologicExpand

Posttherapeutic intraaxial brain tumor: the value of perfusion-sensitive contrast-enhanced MR imaging for differentiating tumor recurrence from nonneoplastic contrast-enhancing tissue.
BACKGROUND AND PURPOSE Differentiation of tumor recurrence from treatment-related changes may be difficult with conventional MR imaging when newly enhancing lesions appear. Our aim was to determineExpand

Perfusion-sensitive MR imaging of gliomas: comparison between gradient-echo and spin-echo echo-planar imaging techniques.
BACKGROUND AND PURPOSE The different sensitivities to vessel size of gradient-echo echo-planar imaging (GE-EPI) and spin-echo EPI (SE-EPI) might indicate the relative cerebral blood volumes (rCBVs)Expand

Evaluation of the intracranial dural sinuses with a 3D contrast-enhanced MP-RAGE sequence: prospective comparison with 2D-TOF MR venography and digital subtraction angiography.
BACKGROUND AND PURPOSE The diagnosis of dural sinus thrombosis is often difficult because of its variable and nonspecific clinical presentation and the overlapping signal intensities of thrombosisExpand

Diffusion-weighted imaging of radiation-induced brain injury for differentiation from tumor recurrence.
BACKGROUND AND PURPOSE Differentiation between tumor recurrence and treatment-related brain injury is often difficult with conventional MRI. We hypothesized that the diffusion-weighted imaging (DWI)Expand

[Percutaneous transluminal angioplasty of the subclavian arteries].
We studied the complications and long-term results of percutaneous transluminal angioplasty (PTA) of subclavian artery stenosis in 11 patients. In all patients but one, the systolic blood pressureExpand
