MR imaging of epilepsy: strategies for successful interpretation.

MR imaging plays a pivotal role in the evaluation of patients with epilepsy. With its high spatial resolution, excellent inherent soft tissue contrast,multiplanar imaging capability, and lack of ionizing radiation, MR imaging has emerged as a versatile diagnostic tool in the evaluation of patients with epilepsy. MR imaging not only identifies specific epileptogenic substrates but also determines specific treatment and predicts prognosis. Employing appropriate imaging protocols and reviewing the images ina systematic manner helps in the identification of subtle epileptogenic structural abnormalities. With future improvements in software, hardware, and post-processing methods, MR imaging should be able to throw more light on epileptogenesis and help physicians to better understand its structural basis.
