Abstract
Purpose: Aim and Objectives of study was to assess the role of MRI in the evaluation of ring enhancing lesions of brain and to assess utility of MR spectroscopy in differentiating various ring enhancing lesions of brain. Methods: The study was carried out in the department of radiodiagnosis. The study was carried out over a period of 16 months and included 50 patients with ring enhancing lesions detected on contrast MR brain. Results: Out of 50 cases in our study, majority of lesions were tuberculoma followed by metastasis and NCC. Majority of patients were females in age group 40-60 years. Headache was the most common presenting symptoms. Majority of lesions were multiple (62%) and (60%) smaller in size (<2cm). Overall sensitivity and accuracy of MR were 81.54%, 92.76% and MRI+MRS were 91.27% and 96.80% respectively. Conclusion: MRI along with MRS has emerged as the most sensitive modality in the characterization of various intracranial ring enhancing lesions. MRS aids in MR diagnosis based on various metabolites leading to near accurate diagnosis.
