Abstract
Objective To investigate the diagnostic performance of magnetic resonance imaging(MRI)diffusion-weighted imaging(DWI)combined with conventional sequences for acute cerebral infarction in elderly patients.Methods A total of 102 elderly patients with suspected acute cerebral infarction who were admitted to Zhumadian Hospital of Traditional Chinese Medicine from March 2023 to March 2025 were retrospectively selected as the study subjects.Using the final clinical diagnosis as the gold standard,70 patients were confirmed positive and 32 were confirmed negative.The diagnostic performance of DWI alone,conventional sequences alone,and their combination for acute cerebral infarction was analyzed,and the detection rates of DWI alone,conventional sequences alone,and their combination for acute cerebral infarction at different stages were compared.Results DWI detected 58 positive cases(56.86%)and 44 negative cases(43.14%);conventional sequences detected 52 positive cases(50.98%)and 50 negative cases(49.02%);DWI combined with conventional sequences detected 77 positive cases(75.49%)and 25 negative cases(24.51%).The sensitivity of DWI combined with conventional sequences for diagnosing acute cerebral infarction was 95.71%,which was higher than that of DWI alone(72.86%)and conventional sequences alone(61.43%).The missed diagnosis rate of the combined diagnosis was 4.29%,which was significantly lower than 27.14%for DWI alone and 38.57%for conventional sequences alone,and the differences were statistically significant(P＜0.05).The detection rates of DWI combined with conventional sequences in the hyperacute stage and acute stage were significantly higher than those of either modality used alone(P＜0.05).Conclusion The combined application of MRI DWI and conventional sequences can significantly improve the diagnostic performance for acute cerebral infarction in elderly patients.In addition,the combination of DWI and conventional sequences can improve the detection rates of cerebral infarction in the hyperacute and acute stages,which helps to establish an early diagnosis and provides a reliable basis for timely clinical intervention.关键词
