초록

목적: 만성 외상성 뇌 손상 환자의 정신의학적 후유 장애 평가에 뇌혈류 SPECT가 유용한 지 알아보았다. 대상 및 방법: 외상성 뇌 손상 후 정신의학적 후유 장애 평가를 위하여 정신과 병동에 입원 중 Tc-99m 뇌혈류 SPECT, 뇌 MRI 및 심리 평가가 시행되었던 69명(남:여=58:11, 연령 $39{\pm}14$세)을 대상으로 하였다. 외상 정도는 경도 31명, 중등도 17명, 중증 21명이었고, 외상 후 Tc-99m HMPAO 뇌혈류 SPECT 촬영까지의 평균 기간은 23개월($6{\sim}61$개월)이었다. 심리 평가에서 나타나는 인지 기능 장애를 기준으로 뇌혈류 SPECT와 뇌 MRI 두 영상 검사의 진단능을 비교하여 보았다. 결과: 심리 평가 결과 42명에서 인지 기능 장애가 있었고, 27명에서 없었다. 뇌혈류 SPECT의 예민도 71%, 특이도 85%이었고, 뇌 자기 공명 영상은 예민도 62%, 특이도 93%로 두검사의 진단능에 통계적으로 유의한 차이가 없었으나(p>0.05, McNemar test), 뇌혈류 SPECT는 피질의 병변을 더 많이 찾았고, 뇌 자기 공명 영상은 백질 병변을 찾는데 우수하였다. 경도 뇌 손상 환자 31명에 대해서도 뇌혈류 SPECT의 예민도 45%, 특이도 90%, 뇌 자기 공명 영상은 각각 27%, 100%로 역시 진단능에 통계적으로 유의한 차이는 없었다(p>0.05, McNemar test). 뇌 자기 공명 영상에서 정상 소견을 보인 41명에서 뇌혈류 SPECT는 예민도 63%, 특이도 88%(꾀병 환자들에서 85%)를 보였다. 결론: 뇌혈류 SPECT는 만성 외상성 뇌 손상 환자들에서 뇌 자기 공명 영상보다 더 많은 피질의 병변을 찾는다. 따라서 뇌혈류 SPECT는 만성 외상성 뇌 손상 환자들의 정신의학적 후유 장애에서 임상심리평가에 보조적 역할을 한다.

Purpose: We studied whether brain perfusion SPECT is useful in the psychiatric disability evaluation of patients with chronic traumatic brain injury (TBI). Materials and Methods: Sixty-nine patients (M:F=58:11, age $39{\pm}14$ years) who underwent Tc-99m HMPAO brain SPECT, brain MRI and neuropsychological (NP) tests during hospitalization in psychiatric wards for the psychiatric disability evaluation were included; the severity of injury was mild in 31, moderate in 17 and severe in 21. SPECT, MRI, NP tests were peformed $6{\sim}61$ months (mean 23 months) post-injury. Diagnostic accuracy of SPECT and MRI to show hypoperfusion or abnormal signal intensity in patients with cognitive impairment represented by NP test results were compared. Results: Forty-two patients were considered to have cognitive impairment on NP tests and 27 not. Brain SPECT showed 71% sensitivity and 85% specificity, while brain MRI showed 62% sensitivity and 93% specificity (p>0.05, McNemar test). SPECT found more cortical lesions and MRI was superior in detecting white matter lesions. Sensitivity and specificity of 31 mild TBI patients were 45%, 90% for SPECT and 27%, 100% for MRI (p>0.05, McNemar test). Among 41 patients with normal brain MRI, SPECT showed 63% sensitivity (50% for mild TBI) and 88% specificity (85% for malingerers). Conclusion: Brain SPECT has a supplementary role to neuropsychological tests in the psychiatric disability evaluation of chronic TBI patients by detecting more cortical lesions than MRI.
