Abstract

Background: Magnetic resonance imaging (MRI) is a cross-sectional imaging technique based on the principle of magnetic resonance of hydrogen atoms due to radio frequency (RF) signals with the same frequency as the precession frequency (lamor frequency). MRI at the beginning of its development used a semiconductor magnetic field with a power of 0.5-1.5 Tesla, but now MRI uses a superconductor magnetic field with a power of 1.5-3 Tesla. One of the advantages of brain MRI in epilepsy cases is that it can display clear information about the anatomy and pathology of the head in general in the temporal lobe area. The use of 3D sequences with isotropic voxels such as SPACE (Sampling Perfection With Application Optimized Contrasts With Varying Flip Angle Evolution) is very useful for generating images with high resolution, thinner cuts, and multi-level reconstruction can be performed in several fragments that allow the acquisition of 3D sequences at one time. Methods: The type used is descriptive qualitative research with a case study approach by conducting interviews with 2 radiology specialists, 1 neurology specialist and 3 radiographers related to MRI brain examinations with clinical epilepsy in August-September 2023 in the Radiology Unit of Prof. Dr. I. G. Ngoerah Denpasar Hospital. G. N. G. Ngoerah Denpasar. Results and Conclusion: This study used five (5) patient data who had clinical epilepsy. Based on the results of observations, interviews and documentation in the radiology unit of Prof. Dr. I.G.N.G. Ngoerah Denpasar Hospital, it can be seen that the procedure for examining MRI Brain with clinical epilepsy is that there is no special preparation, only filling out inform consent. The patient is positioned supine on the examination table with a head fixation device with a head first body position and hands beside the body. Radiographers put the patient into the gantry by setting the isocenter i n the middle of the glabella. After positioning the patient the radiographer sets the parameters using axial T2 Turbo Spin Echo (TSE), sagittal T2 Turbo Spin Echo (TSE), coronal T2 Turbo Spin Echo (TSE), axial T2 Turbo Spin Echo (TSE) dark fluit, axial T1 Turbo Spin Echo (TSE) axial Diffusion Weighted Imaging (DWI) and Susceptibility Weighted Imaging (SWI) and coronal T1 SPACE IR isotropic sequences.In addition, the role of coronal slice T1 SPACE sequences is to clearly see the presence of partical dystrophy, to see the thickening or irregularity of the cortex cerebri clearly. In addition, it is also to see the calcification of the temporal lobe and to measure the volume of the hippocampus.

Abstract

The background of this research is that vertigo is a symptom caused by disturbances in body balance due to the different locations of the lesions. Vertigo is not a disease but a symptomatic condition of vestibular system disorders. Evaluation of patients with audiovestibular disorders, sensorineural hearing disorders, tinnitus, and vertigo . Brain MRI is used to evaluate patients with audiovestibular dysfunction, including sensorineural hearing loss, tinnitus, and vertigo. This research method is descriptive qualitative research with a case study approach using a research design, namely observation, interviews and documentation which aims to find out why the T2 MATRIX 3D SPAIR sequence is needed for MRI brain examinations in vertigo cases at the Radiology Installation at Balimed Hospital, Denpasar. The data collection method was obtained using 3 Brain MRI patients, 3 radiology specialists and 3 radiographers. The results of this research show that the Magnetic Resonance Imaging (MRI) brain examination procedure in Vertigo cases at the Radiology installation at Balimed Hospital Denpasar uses the additional T2 MX3D SPAIR sequence for Vertigo cases because this sequence is able to show the nerve fibers in the brain. The conclusion is that the Magnetic Resonance Imaging (MRI) brain examination procedure in Vertigo cases at the Radiology installation at Balimed Hospital Denpasar does not require special preparation, only more attention is paid to the patient's condition, whether they are wearing braces or dentures because the two tools used will interfere with the results of the MRI image used. The reason for using the T2 MX3D SPAIR sequence is with the aim of adding diagnostic information from the image quality results in order to establish a diagnosis of many neurological disorders or nerve fibers, one of which is Vertigo.
