To analyse the traditional MRI signs, diffusion weighted imaging (DWI), perfusion weighted imaging (PWI), and hydrogen proton magnetic resonance spectroscopy (1H-MRS) of intracranial primary central nervous system lymphoma in immunocompetent people. To explore its diagnostic value.
The paper retrospectively analysed the MRI signs of 12 patients with primary central nervous system lymphoma confirmed by surgery and pathology.
Twelve patients were all B-cell lymphoma. A total of 13 nodules were detected, 11 were single and 1 was multiple. Lesions T1WI showed low or equal signal shadows, T2WI showed equal, slightly higher, high signal shadows, DWI showed high and low signal shadows; the boundaries of the lesions were clearer, and mild to moderate enema was visible around them; most of the lesions showed obvious uniform enhancement and “gap” Signs “and” spike signs “; 1H-MRS showed a moderate decrease in N-acetyl aspartate (NAA) peak, an increase in choline (Cho) peak, and a slight decrease in creatine (Cr) peak, which can be seen Huge lipid peak. Perfusion-weighted imaging suggested that the lesions were hypoperfusion nodules.
The combined application of traditional magnetic resonance imaging, diffusion weighted imaging, perfusion weighted imaging, and 1H-MRS can improve the diagnosis rate of primary central nervous system lymphoma.
