【摘要】目的：观察多层CT脑灌注成像在早期脑梗死诊断中的准确性。方法：本文共纳入澧县人民医院收治的46例早期脑梗死患者，且时间为2022年7月—2023年6月。所有纳入者均进行常规CT诊断与多层CT脑灌注成像诊断。记录46例患者的检查结果，计算不同诊断方式的阳性检出率，并对诊断效能进行对照分析。结果：诊断后，多层CT脑灌注成像诊断结果显示有45例为早期脑梗死患者，有1例为阴性患者；常规CT诊断结果显示有38例为早期脑梗死患者，有8例为阴性患者。多层CT脑灌注成像诊断的阳性检出率高于常规CT诊断(P<0.05)。多层CT脑灌注成像的诊断效能高于常规CT(P<0.05)。结论：在为早期脑梗死患者诊断时，常规CT与多层CT脑灌注成像均可发挥一定诊断效果，但后者效果更高，可提高阳性检出率，增强诊断效能，为后期治疗提供有效参考，推荐参考应用。
