超声、CT、MRI和血清CA19-9对胰腺癌诊断的对比分析

目的：探讨了3种非创伤性影像检查方法,超声（US）、X线计算机体层摄影术（CT）和磁共振成像（MRI）及血清CA19-9水平在胰腺癌诊断中的敏感性和准确性,以提高对早期胰腺癌的诊断方法。方法：回顾性分析比较31例胰腺癌患者的US、CT和MRI及血清CA19-9测定的优缺点。结果：胰腺癌的确诊率US为77.8%,CT为87.2%、MRI为93.8%、CA19-9为70.8%,US对胰腺癌的早期检出率较高,但确诊率较低。CT和MRI对胰腺癌的确诊率较高,血清CA19-9的确诊率也较低。结论：US、CT、MRI和血清CA19-9各有其特点,合理的综合利用,可提高对胰腺癌的早期诊断。

Study on the Diagnostic Advantages of Various Means (Ultrasound Sonography, CT, MRI and Serum CA19-9 Level Determination) for Pancreatic Cancer.

Objective To explore the sensivitiy and accuracy of various diagnostic means（ultrasound sonography,CT,MRI,serum CA19-9 measurement）in patients with pancreatic cancer.Methods The clinical results of these diagnostic means were retropectively assessed in 31 patients with pathologically proven pancreatic cancer.Results A definitive diagnosis was attainable in a higher percentage of patients with CT（87.2%） and MRI（93.8%） while the result with sonography（77.8%） or CA19-9 measurement（70.8%） was lower.Ultrasound examination was the most sensitive one but with less specificity.Conclusion Selectively combined examination with these four means would yield the best diagnostic results in patients with pancreatic cancer.
