Brain tumours in MR imaging

Magnetic resonance (MR) study of the brain using a low-field imager (0.04 T) was carried out in 1035 patients with suspected brain tumors which were detected and confirmed in 593 cases. The most frequent findings were neuroepithelial tumours, meningiomas, hypophyseal adenomas, and various metastasis lesions. MR features of various types were analyzed. Low-field MR imaging helps to detect tumors even of smaller size, localize them, determine their dissemination and the status of the adjacent tissues, thus providing (similarly as high- and middle-field MR imaging) valuable diagnostic information.
