Abstract

AbstractIntroductionThis research aimed to see how well magnetic resonance spectroscopy (MRS) could identify the lateralization side in individuals with temporal lobe epilepsy (TLE) compared to electroencephalography (EEG) and magnetic resonance imaging (MRI) results.MethodsTwenty‐three individuals were included in this research and diagnosed with TLE (both clinically and by EEG). Clinical exams, interictal EEG, and MRI were performed on all patients. In addition, the individuals were also subjected to proton MRS.ResultsThe age range of 23 participants was 20–55 years (mean = 34.6 ± 8.5); 10 were male (44%), and 13 were female (56%). The right temporal lobe MRI showed a sensitivity and specificity of 60% and 55% for detecting mesial temporal lobe sclerosis (MTS) foci, respectively (positive predictive value (PPV) of 27% and negative predictive value (NPV) of 83%). MRI showed 83% sensitivity and 35% specificity for MTS foci in the left temporal lobe (PPV of 31% and NPV of 86%). MRS showed 61% sensitivity and 100% specificity in the right temporal lobe (PPV 100%) and 80% sensitivity and specificity in the left temporal lobe (PPV 100%) for identifying MTS foci. Overall, MRS (both left and right) results matched EEG findings.ConclusionMRS is a potential noninvasive neuroradiology technique for assessing epilepsy patients because it is more sensitive than structural MRI in identifying MTS. The results of the study overall appears to be of interest but still need further support from future studies with larger sample sizes.
