Abstract:
In the diagnosis of head injury, Magnetic Resonance Imaging(MRI), like CT, is an effective method ofdistinguishing between intracerebral lesions. In our experience of MRI, early hematomas are almost isointense bySaturation Recovery(SR) method, so these must be perforemd with Spin Echo (SE) method for better visualization ofhematomas. Isodense subdural hematomas, which is a diagnostic dilemma on CT images, are clearly seen on MRI.Delayed hematomas or residual parenchymal lesions are better demonstrated on MRI than on CT. Direct cornal,sagittal images and multiplanar facility of MRI provides excellent visualization of the location and shape ofextracerebral collection of hematoma. For the screening of head traumas, SE method is a technique of choicebecause of its excellent sensitivity wihin limited time.
