FIELD: radiodiagnosis and medical imaging.
SUBSTANCE: used to identify focal changes in cortical, infratentorial and spinal localization in multiple sclerosis (MS). Magnetic resonance imaging (MRI) of the brain is performed with a magnetic induction value of 3 Tesla. In this case, the brain study is carried out using the 3D T1 MP2RAGE sequence with the following parameters: TR/TE=5000/2.98 ms, TI1/TI2=700/2500 ms, FA1/FA2=4°/5°, FOV=256 with cervical spinal cord capture, slice thickness 1.0 mm and total scan time TA=8 min 22 sec. Focal changes are detected while simultaneously identifying foci of hypointense MR signal of cortical, infratentorial and spinal localization.
EFFECT: improving the accuracy of detecting focal changes simultaneously in the brain and spinal cord in patients with MS while reducing the total scanning time by eliminating additional sequences for examination.
