- W2113169594 abstract "<h3>BACKGROUND AND PURPOSE:</h3> Volumetry may be useful for evaluating treatment response and prognosis of intraocular lesions. Phantom, volunteer, and patient studies were performed to determine whether ocular MR volumetry is reproducible. <h3>MATERIALS AND METHODS:</h3> Half-Fourier single-shot RARE and FSPGR sequences at 1.5T with a 76-mm-diameter surface coil were optimized to obtain still ocular images. Volumetry accuracies of each sequence were compared with simulated subretinal phantom volumes. Ocular volumetry was performed in 15 volunteers twice in 1 week by using contiguous axial images of the globes while the subjects stared at a target, and images were acquired in 2 seconds before the subjects were instructed to blink, with this process repeated as necessary. Imaging, intraobserver, and interobserver reproducibility for volumes of the whole eyeball and anterior chamber were assessed. Ocular volumetry was also performed in 6 patients with intraocular tumors before and after treatment. <h3>RESULTS:</h3> The phantom study demonstrated that measurement error rates with RARE were significantly lower than with FSPGR (<i>P</i> < .01). The volunteer study demonstrated excellent imaging and intraobserver reproducibility of RARE volumetry for whole eyeballs and anterior chambers (<i>P</i> < .01). Although no interobserver differences were observed in anterior chamber volume measurement (<i>P</i> = .33), there was a significant difference between the 2 observers in eyeball volume measurement (<i>P</i> < .01). Follow-up volumetric data were useful for treatment decisions in all patients. <h3>CONCLUSIONS:</h3> Ocular volumetry from contiguous ultrafast RARE images obtained during visual fixation is feasible in volunteer and patient studies and is superior to FSPGR images." @default.
