뇌졸중의 진단 검사 및 검진
신경학적 검사
신경계 질환에 대한 진찰로서 검안경검사, 팬 라이트, 해머나 바늘, 소리굽쇠 같은 여러 가지 기구를 이용하여 신경계의 전반적인 이학적 검사를 하게 됩니다.



뇌혈관 질환 때 이용하는 특수 검사들


1)전산화 단층 촬영 (CT)
뇌졸중이 발생 했을 때 초기에 출혈인지 혹은 경색인지를 쉽게 감별하고 병변의 위치를 확인할 수 있으며 검사시간이 적게 걸리고 비용이 MRI에 비해 저렴한 장점이 있습니다.



2) 자기공명영상(MRI/A)
뇌경색 발병 30분 후부터 병변을 볼 수 있고 수시간 이내에는 대부분 확인할 수 있으며,뇌간의 병소도 정확히 보여 CT보다 우수한 면이 있습니다.


또한 뇌출혈 병변에서 시간 경과와 원인을 추측할 수 있는 장점이 있습니다.

그 밖에도 내경동맥이나 기저동맥, 대뇌혈관의 폐색유무 등 뇌혈관의 구조를 자세히 볼 수 있습니다.



3) 혈관조형술
MRA보다 좀 더 정확한 혈관의 상태를 파악하거나 스텐트 삽입술 등 시술이 필요한 경우에는 좀 더 침습적인 방법이기는 하지만 대퇴동맥을 통한 뇌혈관조형술을 시행하게 됩니다.

이것은 대퇴동맥으로 긴 바늘을 넣어 뇌혈관까지 다다르게 한 후 혈관이 잘 보이도록 혈관 조영제를 주사하여 혈관을 관찰하는 방법입니다.

4) 경동맥 초음파
뇌경색의 원인이 되는 동맥경화를 뇌혈관의 기원이 되는 경동맥의 초음파 검사를 통해 확인하는 방법입니다.

통증없이 비침습적으로 짧은 시간에 마칠 수 있다는 장점이 있습니다.



5) 뇌혈류(경두개)초음파 검사 (TCD)
이는 초음파를 이용하여 뇌혈관의 혈류 속도를 측정함으로써 뇌혈관의 협착 여부를 간접적인 방법으로 환자의 불편 없이 알아낼 수 있는 유용한 검사입니다.



6) 그 이외의 검사법
그 이외에도 고가의 장비에 속하는 양전자방출단층술(PET), 뇌출혈진단에 도움이 되는 뇌척수액 검사, 심장의 이상유무를 알아내는 심장 초음파 등 다양한 검사로 도움을 받을 수 있습니다.
