만성 두부외상 환자에서 뇌 SPECT 임상적 유용성 및 CT와의 비교 = Clinical Utility of 99mTc-HMPAO Brain SPECT and Comparison with CT in Chronic Symptomatic Head Trauma Patients

다국어 초록 (Multilingual Abstract)

PURPOSE : To compare brain SPECT with CT and evaluate clinical utility of brain SPECT in symptomatic chronic head trauma patients.
MATERIAL AND METHOD : Clinically, CT and SPECT findings of 61 Patients with chronic organic mental disorder for 6 months or more after head trauma were retrospecively reviewed. We analyzed focal low density, atrophy, ventricular dilatation in CT and perfusion defect area in SPECT, and compared clinical findings, CT and SPECT result each other.
RESULT : Twenty-one patients(35%) showed abnormality in CT and 51 patients(84%) in SPECT. In patients with abnormal CT findings, the most frequent lesion was focal low density in the frontal lobe and the most prevalent clinical symptom was personality change. On the other hand, in patients with normal CT indings 36 patients showed abnormal SPECT, among which the most frequent lesion was perfusion defect in the temporal lobe and the most prevalent clinical symptom was amnesia and attention disorder. Three patients showed abnormal CT, but normal SPECT.
CONCLUSION : SPECT is a more sensitive method than CT in evaluating chronic symptomatic head trauma patients, and therefore, can be useful particularly in patients with normal CT finding.
