Role of MR Spectroscopy in Evaluation of Various Ring Enhancing Lesions in Brain
Journal Title: International Journal of Medical Science and Diagnosis Research (IJMSDR) - Year 2018, Vol 2, Issue 4
Abstract
Background-A wide range of etiologies may present as multiple ring-enhancing lesions in brain, including infectious, neoplastic, vascular or inflammatory etiology. Methods-This study was a prospective observational study. The study included 120 patients referred to the department of Radiodiagnosis in SMS medical college, Jaipur with clinically suspected ring enhancing lesions or those detected on contrast enhanced CT scan in the period of 1yrs. Results- Out of the 120 patients that were evaluated spectroscopy was done in all the cases. The spectroscopy finding revealed - Lipid peak was observed in 62 cases, Choline in 44 cases, Lactate in 32 cases, reduced NAA peak was noted in 21 cases Conclusion- MRI along with MRS has emerged as the most sensitive modality in the characterization of intracranial ring enhancing lesions. MRS helps in differentiation and characterization of various ring enhancing lesions based on various metabolites leading to accurate diagnosis. Keywords- MRI, Ring Enhancing Lesions, Tuberculoma.
