Abstract

PURPOSE: To test the accuracy of fast spin-echo (FSE) imaging versus that of double-echo conventional spin-echo (CSE) imaging in identification of the increased hippocampal signal intensity associated with mesial temporal sclerosis (MTS). MATERIALS AND METHODS: Thirty-four subjects who subsequently underwent anterior temporal lobectomy for intractable seizures and in whom the presence or absence of MTS was ascertained with cer-tainty were imaged with CSE and FSE. Three blinded reviewers evaluated the first and second CSE images (CSE1 and CSE2) and the FSE images. RESULTS: CSE1 imaging had lower accuracy than FSE (P = .038) and CSE2 (P = .006) imaging. CSE2 imaging was slightly more accurate than FSE imaging (P = .048). Contrast-tonoise ratios were lower for CSE1 imaging than for CSE2 or FSE imaging (P < .001). CONCLUSION: The FSE sequence evaluated was more time efficient than CSE imaging but slightly less accurate. Therefore, substitution of this sequence for a CSE sequence seems unwarranted.
