Abstract
Introduction: Brain tumors are the second leading cause of cancer related deaths in children and young adults, being common among all age groups. Diagnosis of intraxial brain tumors is very crucial since they are usually very advanced at the time of diagnosis. MRI, with the advent of advanced modalities such as Diffusion Weighted Imaging and Magnetic Resonance Spectroscopy, has gained an ever-increasing multifaceted role in the diagnosis of brain tumors. The role of conventional and advanced MRI in the diagnosis of intra-axial neoplasms need to be ascertained.
Materials and Methods: This is a prospective observational study undertaken over a period of two years on 52 patients evaluated by MRI with the aim to evaluate the characteristic MR findings of various intra-axial supratentorial neoplasms and to assess the additive role of advanced imaging in its diagnosis.
Results: The most commonly encountered neoplasm was high grade glioma followed by metastases. Diagnostic accuracy of MRI was 80.7% and upon addition of advanced imaging it was 94.2%.
Conclusion: Advanced MR imaging modalities should be mandatory for evaluation of intraaxial mass lesions.
Keywords: diffusion weighted, magnetic resonance perfusion, spectroscopy, enhancement.
