Role of Mri In Corelation With Mr Spectroscopy in the Evaluation Of Ring Enhancing Lesions in Brain.

Abstract

Background & Objectives This study is conducted to evaluate characteristic imaging findings in various ring enhancing lesions and their characterization. Objectives • Differentiate neoplastic vs non neoplastic brain lesions using conventional and advanced MR imaging techniques. • Characterization of various ring enhancing lesions with imaging findings. • Establish a differential diagnosis of the various ring enhancing lesions on conventional MRI. • The role of MR spectroscopy in various ring enhancing lesions of brain with a single voxel proton MR spectroscopy and multiple voxel proton MR spectroscopy. Methods Overall 32 patients including 20 males & 12 females were evaluated in this study conducted at Shri B. M. Patil Medical College, Hospital & Research Center, Vijayapura from Nov 2018 to April 2020 over a period of 1& ½ years . MRI along with MRS was performed using PHILIPS ACHIEVA 1.5T & GE SIGNA 1.5T in patients ranging from ages of 10 months to 76 years. Results Out of the 32 patients evaluated 12 cases were tuberculomas, 8 cases of high grade glioma, 4 metastasis, 4 were NCC, 3 abscesses and 1 case of lymphoma. Seizures are the commonest presenting complaint seen in 32 cases.

MRI with help of MRS shows characteristic imaging findings which helps in differentiating the various RELs. Also it plays a major role by suggesting the correct diagnosis based on characteristic imaging findings which helps in patient management.
