 note = {The sensitivity of MRI for intracerebral traumatic lesions was compared with CT findings in 154 minor head-injured patients. The severity of head injury determined by the Glasgow Coma Scale was ranged from 9 to 15. CT and MRI were performed within 72 hours after injury in all patients. MRI was taken with a  0.15 Tesla Sanyo SNR-15P. Pulse sequences included spin-echo sequence with TR 500 or 600 msec and TE 40 msec for a T1 weighted image and spin-echo sequence with TR 2000 msec and TE 80 msec for a T2 weighted image. Intracranial traumatic lesions were detected in 34 (22.1%) of 154 patients by both CT and MRI, 20 (13.0%) by MRI alone, and 4 (2.6%) by CT alone. In these patients with traumatic lesions, 92 lesions were seen by CT and 128 by MRI. Thirty-nine (50.6%) of 77 intracerebral traumatic lesions detected by MRI (T2WI) were not demonstrated by CT. There was no intracerebral traumatic lesion detected by CT alone. MRI (T2WI) was superior to CT for detecting intracerebral traumatic lesions, but MRI was equal to CT for detecting extracerebral lesions such as subarachnoid hemorrhage, T2 weighted image is especially effective for evaluating acute stage of mild head trauma, and recommended for detecting intracerebral traumatic lesions. MRI (T1 and T2 weighted image) is much more useful than CT for studying pathological change of brain following head injury such as contusion, cerebral edema, intracerebral hemorrhage and shearing injury.},
