Evaluation of Intracranial Ring Enhancing Lesions by MRI and MR Spectroscopy

This aim of the study was to evaluate the diagnostic advantage of MRI and MR spectroscopy in Intracranial Ring Enhancing Lesions. Routine MR imaging of the brain is very sensitive in the identification of ring-enhancing lesions, but it lags some specificity. MR spectroscopy is critical for distinguishing brain abscesses from noninfectious lesions such as primary brain tumours, lymphomas, and metastases. Results - Tuberculomas (48%) were the most common disease among the 100 patients investigated, followed by NCC (31%), Abscesses (9%), Metastasis (8%), and Primary brain tumour (4%).
