MR of hippocampal sclerosis: comparison of qualitative and quantitative assessments.
PURPOSE Our goal was to compare the diagnostic accuracy of subjective visual assessment versus MR volumetry in evaluating hippocampal sclerosis and to determine whether MR volumetry is needed in the lateralization of this disease process. METHODS MR imaging findings were studied retrospectively in 48 patients who underwent surgery for temporal lobe epilepsy and were compared with findings at ...
متن کاملOptimizing the diagnosis of hippocampal sclerosis using MR imaging.
PURPOSE To establish the optimal imaging parameters and MR features of hippocampal sclerosis. METHODS Twenty-five outpatients with intractable temporal lobe epilepsy and 10 control subjects were studied at 1.5T. Four features of hippocampal abnormality were specifically evaluated; increased hippocampal signal on T2-weighted images, decreased signal on T1-weighted images, hippocampal atrophy, ...
متن کاملRegional distribution of MR findings in hippocampal sclerosis.
PURPOSE To investigate the distribution of MR findings in the hippocampus and amygdala in patients with hippocampal sclerosis. METHODS We blindly evaluated MR scans for atrophy and signal changes occurring in the amygdala, hippocampal head, hippocampal body, and hippocampal tail in 57 consecutive patients with hippocampal sclerosis proved by pathologic analysis. RESULTS Regional atrophy or ...
متن کاملHippocampal Sclerosis: Correlation of MR Imaging Findings with Surgical Outcome
OBJECTIVE Atrophy and a high T2 signal of the hippocampus are known to be the principal MR imaging findings of hippocampal sclerosis. The purpose of this study was to determine whether or not individual MRI findings correlate with surgical outcome in patients with this condition. MATERIALS AND METHODS Preoperative MR imaging findings in 57 consecutive patients with pathologically-proven hippo...
متن کاملHippocampal internal architecture and postoperative seizure outcome in temporal lobe epilepsy due to hippocampal sclerosis
PURPOSE Semi-quantitative analysis of hippocampal internal architecture (HIA) on MRI has been shown to be a reliable predictor of the side of seizure onset in patients with temporal lobe epilepsy (TLE). In the present study, we investigated the relationship between postoperative seizure outcome and preoperative semi-quantitative measures of HIA. METHODS We determined HIA on high in-plane reso...
