Analisis Informasi Citra Anatomi Antara Sekuen 3D CISS dan 3D SPACE Pada MRI Brain Potongan Axial Dengan Klinis Trigeminal Neuralgia

Abstract

Background: MRI examination of the brain using 3D CISS and 3D SPACE sequences is often used for cranial nerve-related diagnosis. MRI can show images of cranial nerves, subtentorial masses, and neurovascular compression. In this study, the Radiology Installation of RSPON Prof. Dr. Mahar Mardjono Jakarta used 3D SPACE sequences, but there were differences in the selection of sequences used in several other hospitals. The purpose of this study is to determine the difference in anatomical image information and the most optimal sequence in displaying image information between 3D CISS and 3D SPACE sequences with trigeminal neuralgia.

Methods: This study was conducted on 10 patients with trigeminal neuralgia in the range of 40 - 75 years. The image assessment was carried out by three radiology specialists by assessing the clarity of CN V, root entry zone, Meckel's cave, SCA, and AICA. Anatomical information which was assessed with a score range of 1-3. The resulting data was ordinal data. Data analysis was carried out using the Wilcoxon statistical test.

Results: The results of this study showed that there was a difference in anatomical image information between 3D CISS and 3D SPACE sequences which showed a p-value of 0.00 (p < 0.05). This study also shows that there was a difference in information from each anatomy assessed, so that the more optimal sequence in providing an overview of anatomical information on MRI examination of axial brain with trigeminal neuralgia is the 3D SPACE sequence with a mean rank value 25.00.

Conclusions: There was a difference in anatomical image information between 3D CISS and 3D SPACE. 3D SPACE can provide a more optimal image of anatomical information and sharper image results when compared to 3D CISS and a shorter scanning time.
