Abstract

Objectives: Characteristics of magnetic resonance imaging of supratentorial cerebral hemisphere tumors undergoing brain biopsy at Military Hospital 103. Subjects and methods: The study was conducted on 30 patients diagnosed with supratentorial cerebral hemisphere tumors at the Department of Neurosurgery - Military Hospital 103 from January 2020 to December 2022. Evaluation of clinical characteristics of brain tumors on magnetic resonance. Results: Magnetic resonance images showed mainly decreased signal on T1 (56.7%), increased signal on T2 (86.7%), and enhancement after injection (90%); all had brain edema around the tumor (100%), mild midline compression, mainly grade I (60%). The tumor location is highest in the frontal lobe (23.3%), then the temple (20%), and in the deep brain region (20%). The rate of multiple foci and multiple locations is high at 23.3%. The average tumor size was 41.7 ± 18.4 mm. Conclusion: Magnetic resonance images of supratentorial cerebral hemisphere tumors often show decreased signal on T1, increased signal on T2, post-injection drug enhancement, peritumoral cerebral edema, and mild midline deviation.
