147 CT guided fine-needle biopsies of the pancreas were carried out on 141 patients (45 malignant tumours, 79 chronic pancreatitis and pancreas without lesions, respectively). In 23 pseudocysts a malignant lesion could be excluded. By analysing the remaining 124 biopsies (non-cystic targets) an overall accuracy of 79%, a sensitivity of 71% and a specificity of 84% in differentiating between benign and malignant lesions were obtained. By excluding 12% of biopsies with no diagnostic material, an overall accuracy of 90% might be recorded. The comparison between the number of aspirates per examination and the cytological diagnoses would indicate that a minimum of four aspirates is required for satisfactory results.
对141例患者进行了147次CT引导下胰腺细针穿刺活检（分别为45例恶性肿瘤、79例慢性胰腺炎和无病变的胰腺）。在23个假性囊肿中可以排除恶性病变。通过分析其余124次活检（非囊性靶点），在鉴别良性和恶性病变方面，总体准确率为79%，敏感性为71%，特异性为84%。排除12%无诊断材料的活检后，总体准确率可能达到90%。每次检查的抽吸次数与细胞学诊断之间的比较表明，为获得满意结果至少需要4次抽吸。
