EVALUATION OF RING ENHANCING LESIONS IN BRAIN IN CORRELATION WITH ARTERIAL SPIN LABELING AND MR SPECTROSCOPY

Abstract

BACKGROUND: Ring enhancing intracranial lesions are common and are considered as a diagnostic dilemma. Although MRI has been established as the most reliable diagnostic methods, it had limited role in quantitative and functional assessment. ASL and MRS can also help in differentiating the high-grade forms from low grade tumours. Further classify ring enhancing lesions, will help in better diagnosis, classification, grading and treatment. Hence, the present study was conducted to analyse ring enhanced lesions on MR scan by using such advanced diagnostic techniques and classify the tumours
