应用SPECT局部脑血流断层显像依据ROI比值测定法，测定66例脑出血患者局部脑血流比值，结果发现，局部脑血流比值下降与出血量及出血部位密切相关.出血量越大，脑血流下降越明显。内囊部位出血局部脑血流比值下降明显。
Local cerebral blood flow tomography using SPECT ROI ratio determination of 66 cases of cerebral hemorrhage in patients with local cerebral blood flow ratio and found that the local cerebral blood flow value decreased with the amount of bleeding and bleeding is closely related to the greater the amount of bleeding, Cerebral blood flow decreased significantly. Local cerebral hemorrhage local cerebral blood flow rate decreased significantly.
