Purpose: Compare Computed Tomography and Magnetic Resonance Imaging to accurately determine the volume of brain tumors for radiotherapy. Methods and Materials: Cross-sectional descriptive study on 38 patients with brain tumors indicated for radiation therapy, underwent Magnetic Resonance Imaging and CT scans at Hue Central Hospital from January 2018 to July 2019. Data processed with MS Excel 2013, SPSS 20.0 and statistical algorithms. Results: The Magnetic Resonance Imaging has a rate of brain tumor detection of 100% while that of computed tomography only reached 60.5%. The average difference in tumor size is 0.66 cm, the size of the tumor is larger on the magnetic resonance images. There is a close agreement on Magnetic Resonance Imaging and computer tomography on the level of cerebral edema (kappa = 0.735, p <0.001), on the amount of mid line shift of the tumor (kappa = 0.775, p <0.001); and detected cocoons in tumor (kappa = 1.000, p <0.001). Conclusions: Magnetic Resonance has advantages over computed tomography in the ability to detect brain tumors, tumor margin, the ability to detect the level of cerebral edema, invasive properties and identify cocoons in tumors. Computed Tomography is more advantageous than Magnetic Resonance in cases with calcification in the tumors or bone changes. Fusing computed tomography images and Magnetic Resonance Imaging together is a more effective method of determining the volume of brain tumors for radiotherapy.
