Abstract：ObjectiveTo investigate the unique advantages of MRI t2 tirm dark-fluid in the imaging diagnosis of temporal lobe epilepsy caused by hippocampus sclerosis in children and adolescents compared with other multisequence scanning methods.Methods60 cases of children clinically confirmed as hippocampus sclerosis were scanned in multiple sequences using a Siemens Avanto Dot 1.5 TMR machine. The display rates of each sequence of intracranial lesions were compared, statistical comparisons were made, and the images obtained were analyzed.ResultsLeft hippocampus sclerosis in 21 cases. 36 cases on the right side and 3 cases on both sides. In the normal T2WI TES, FLAIR, T2 tirm and t2 tirm dark-fluid sequences, 28 cases, 39 cases, 42 cases and 51 cases respectively showed high signals. After statistical analysis, the incidence of t2 tirm dark-fluid sequences lesion was highest, and the differences with conventional T2WI TES, FLAIRand T2 tirm were statistically significant (P<0.05). The difference between the FLAIR and t2 tirm sequences (P>0.05) was not statistically significant.ConclusionMRI is the preferred device and method for diagnosing hippocampus sclerosis. Imaging doctors should pay full attention to the importance of T2 tirm dark-fluid in brain black water+fat inhibition sequence. It can significantly shorten the time of examination to improve the accuracy of diagnosis, for clinicians to provide accurate positioning and qualitative diagnosis, worthy of reference in the future work.
