뇌동맥류파열에 의한 지주막하출혈 환자에서 99mTc - HMPAO SPECT 검사의 유용성 = Usefulness of 99mTc - HMPAO SPECT in Patients with Subarachnoid Hemorrhage due to Ruptured Intracranial Aneurysm

다국어 초록 (Multilingual Abstract)

We evaluated the usefulness of Tc-99m-HMPAO SPECT in 21 Patients with subarachnoid hemorrhage due to ruptured intracranial aneurysm and in 3 patients with unruptured intracranial aneurysm. SPECT study could detect the bilaterally hypoperfused cases in 10 patients(48%), but CT/MRI showed the bilateral abnormalities in only 3 patients(14%). The number of abnormal lesions were 56 in SPECT and 25 in CT/MRI. The lesions found in SPECT were well correlated with the neurological signs of the patients such as aphasia or hemiplegia. SPECT study during Matas test was helpful in evaluating the risk for carotid artery occlusion therapy. We thought that Tc-99m-HMPAO brain SPECT is helpful in evaluating the functional changes in patients with subarachnoid hemorrhage.
