CT增强扫描对外伤性脾破裂的诊断价值

目的　探讨CT增强扫描在外伤性脾破裂诊断中的应用价值。方法　对 34例经手术证实为外伤性脾破裂患者的CT平扫及增强扫描表现进行回顾性分析。结果　34例患者中,手术前CT平扫能肯定脾破裂诊断的 23例、可疑脾破裂诊断的 6例、未见异常的 5例(敏感性 85. 3%、特异性 67. 6% );对以上所有患者行CT增强扫描后,全部患者均能确诊为脾破裂(敏感性 100%、特异性 100% )。结论　增强扫描在外伤性脾破裂的CT诊断中非常重要,它能够明显提高诊断准确率,为临床治疗提供可靠依据。

The Diagnostic Value of Contrast-enhanced CT Scans for Traumatic Splenic Rupture

Objective To evaluate the diagnostic value of contrast-enhanced CT scans in diagnosis of traumatic splenic rupture. Methods The findings of unenhanced and contrast-enhanced CT scans of 34 cases with traumatic splenic rupture confirmed by operation were retrospectively reviewed. Results Of the 34 patients, the diagnoses of splenic rupture on unenhanced CT scans were certain in 23 patients and uncertain in 6 patients. No abnormalities were found in 5 patients(sensitivity 85.3%, specificity 67.6%). After intravenous administration of contrast material, all of the patients were diagnosed as splenic rupture(sensitivity 100%,specificity 100%).Conclusion Contrast-enhanced CT is important in diagnosis of traumatic splenic rupture and can obviously improve the diagnostic accuracy. It provides reliable information for clinical treatment.
