In the diagnosis of head injury, Magnetic Resonance Imaging *MRI), like cT, is an effective method of distinguishing between intracerebral and extracerebral lesions. In our experience of MRI, early hematomas are almost isointense by Saturaion Recovery(SR) method, so these must be performed with Spin Echo (SE) method for better visualization of hematomas. Isodense subdrual hematomas, which is a diagnostic dilemma on CT images, are cleary seen on MRI. Delayed hematomas or residural parenchymal lesions are better demonstrated on MRI than on CT . Direct cornal , sagittal images andmultiplanar faciligy of MRI provides excellent visualization of the location and shape of extracerebral collection of hematoma. For the screening of head traumas, SE method is a technique of choice because of its excellent sensitivity.
