摘要
目的评价CT平扫与增强扫描对胰腺癌的诊断与鉴别诊断价值。方法24例经手术病理或临床证实的胰腺疾病患者,包括胰腺癌(12)例,慢性胰腺炎(7例),胰腺转移瘤(2例),胰腺囊腺瘤(1例),胰腺结核(1例),以及胰头变异(1例),均经增强前与增强后CT扫描,并对全部病例的CT表现进行回顾性分析。结果24例胰腺病变患者中,恶性病变(胰腺癌与转移瘤)14例(58%),良性病变10例(42%)。各种胰腺疾病的影像表现随其为良性或恶性病变而不同,例如,胰腺癌患者表现为瘤内的不均匀密度,增强扫描后病变无强化,而慢性胰腺炎患者则表现为病变密度均匀,增强扫描后病变均匀强化。结论CT扫描,尤其是CT增强扫描有助于将胰腺癌与其他胰腺疾病相鉴别。
Objective To assess the value of CT scan without and with contra st enhancement in the diagnosis and differential diagnosis of pancreatic carcinoma .Methods Twenty-four patients with surgically,pathologically or clinically prov ed pancreatic diseases which included pancreatic carcinoma(n=12),chronic pancrea titis(n=7),pancreatic metastases(n=2),pancreatic cystadenoma (n=1),pancreatic tu berculosis(n=1),and pancreatic head variation(n=1)underwent precontrast and post contrast CT scans.The imaging findings in all patients were analyzed retrospecti vely.Results Among 24 patients,malignant lesions(carcinoma and metastasis)were f ound in 14 cases (58 %)while benign lesions were found in 10 cases (42 %).CT f indings of varied diseases with maltignant or benign lesion were different,for e xample,pancreatic carcinoma and metastasis presented as intratumoral nonhomogene ous density and postcontrast non enhancement while chronic pancreatitis presente d as homogeneous density in the lesions and postcontrast homogeneous enhancement of the lesions.Conclusion CT scans,in especially,postcontrast enhanced scans ar e helpful to differentiate pancreatic carcinoma from other pancreatic diseases.
