Abstract
Objective To study the CT perfusion imaging and CT angiography characteristics of transient ischemic attack (TIA). Methods To analyze 40 standard patients’ CT perfusion imaging and CT angiography data. Results The MTT of the diseased area were higher than that of the image area, the CBF were lower than that of the image area, which suggested statistical significance (P < 0. 05), their CBV were similar, without statistically significant difference (P > 0. 05). The MTT of stage I pa-tients were lower than stage II, the CBF were higher than that of stage II, which suggested statistically significant (P < 0. 05);Their CBV were similar without statistically significant difference (P > 0. 05). CT angiography showed 31 cases responsible angio-stegnosis ; 27 cases of them showed abnormal CT perfusion imaging, the positive rate was 87. 10% ;CT angiography showed 9 cases responsible blood vessels without narrow, 3 cased of them CT perfusion imaging abnormal , the positive rate was 33. 33% ;which suggested significant difference (P < 0. 05). Conclusion CT perfusion imaging can be used to evaluate TIA patients’ he-modynamic changes, combined with head and neck CT angiography, which has important clinical value for TIA’s etiology diagnosis and condition assessment, worthy of clinical popularization and application.关键词
