To determine whether perfusion-weighted and proton spectroscopic MR imaging can be used to differentiate high-grade primary gliomas and solitary metastases on the basis of differences in vascularity and metabolite levels in the peritumoral region.Fif

As described earlier, if MR angiography is to replace conventional angiography, the entire course of the carotid arteries should be imaged. De Marco et al describe initial success in imaging the entire circulation from the aortic arch through the cir

OBJECTIVE Our goal was to implement 512 and 1024 matrix MRI of the brain in clinically acceptable imaging times. MATERIALS AND METHODS With use of the GRASE (gradient-SE) imaging technique, 3 signals are refocused from each of 16 SEs, giving a total

Equal time spacing of RF pulses in the CPMG sequence imposes a constraint of equal signal read periods in spin-echo train imaging. GRASE imaging differs by using multiple read gradients in each π-π time interval, which are not constrained to be equ

To determine the accuracy of magnetic resonance angiography in assessing patients with cerebrovascular disease, we performed a study comparing the results of conventional cerebral angiography, duplex scanning, and magnetic resonance angiography. From

We have previously shown that 5 mm axial T1-weighted images following Gd-diethylenetriamine pentaacetic acid (DTPA) administration were sufficient as a screening examination of the internal auditory canal (IAC) and cerebellopontine angle cistern in 8

The relative efficacy of post-Gd-DTPA 5 and 3 mm axial T1-weighted images was compared in the detection of lesions in the internal auditory canal and cerebellopontine angle. One hundred twenty consecutive patients were prospectively evaluated with 5
