Noninvasive Grading of Untreated Gliomas: A Comparative Study of MR Imaging and 3-(Iodine 123)-L-α-methyltyrosine SPECT

Abstract

Although (123)I-IMT uptake is significantly higher in high-grade gliomas than in low-grade gliomas, the performance of (123)I-IMT SPECT adds little to the accuracy of determining tumor grade when MR imaging is performed.
