Magnetic-resonance image in diagnostics of intrinsic spinal cord tumors
V.I. TSYMBALYUK, R.B. KOSTRYTSYA

Purpose – to create diagnostics MRI algorithm of patients with intrinsic spinal cord lesions.

Methods and subjects. Retrospective analyzes of the MRI-data of the 195 patients with intrinsic spinal cord lesions was carried out. It was performed in-patients or out-patients departments in the State institution "Institute neurosurgery named after acad. A. Romodanov" AMS of Ukraine from 1995 until 2006 years. Patients groups included 154 patients with intrinsic spinal cord tumors and 41 – with non-tumoral lesions. All cases have been vivificated operatively in the first spinal and first children departments, histologically in the department of the neuropathomorfology of the institute.

Results. The frequency and detailed characteristics of the MRI-signs were defined, the possibility to forecast the histological type of the intrinsic spinal cord tumors was estimated, the optimal data needed for surgical resection of the tumors were defined as well. Cases for obligatory Т1en images are: impossibility of intrinsic spinal cord lesions.diagnosis according to Т1- and Т2- images assesment, noninformaive MRI-images considering surgery.

Conclusions. MRI is a valuable diagnostics method that allows to carry out early diagnostics of intrinsic spinal cord lesions. Histological type of intrinsic spinal cord lesions is possible if there are native and contrast images. Two diagnostic models of intrinsic spinal cord lesions have been developed: ependymoma and astrocytoma. Optimal MRI data includes: spinal tumor, determination of timor borders, bones characteristics, sides of exophytic component growth, possible histological type.
