ABSTRACT
Intracranial space occupying lesions (ICSOL) represent one of the most commonly encountered abnormalities in brain. The availability of computed tomography (CT) and conventional magnetic resonance imaging (MRI) have revolutionised the approach towards diagnosis and management of intracranial lesions. Majority of intracranial lesions can be reliably diagnosed on conventional MRI. However many times it is difficult to differentiate brain pathologies on the basis of CT scan or conventional MRI. In such cases, advanced MRI sequences such as diffusion weighted imaging (DWI), perfusion weighted imaging (PWI) and proton magnetic resonance spectroscopy (MRS) can be helpful in making a reliable and accurate diagnosis. Herein, we describe importance of advanced MRI sequences in diagnosing various ICSOLs which were extremely hard and confusing to differentiate on conventional MRI.
