Objective To study the value and the clinical application of the Medical Image three-dimensional Visualization System of Abdomen (MI-3DVS) in diagnosis and evaluating resectability of pancreatic tumor. Methods Twelve patients with pancreatic tumor were tested with 64-slice helical CT(64-MSCT) angiography,and the CT data was reconstructed with MI-3DVS from November 2008 to August 2009. The 3D findings were adopted in diagnosis and evaluating resectability,and the results were compared with surgical operation and the pathological finding. There were 7 male and 5 female, aged from 14 to 83 years. Within the 12 cases, there were 4 cases with pancreatic carcinoma,5 cases with pancreatic solid pseudopapillary tumor, 2 cases with pancreatic serous eystadenoma, 1 ease with pancreatic cyst (ductal epithelial papillary hyperplasia). Results Nine tumors which had been regarded as removable pre-operatively with MI-3DVS were removed successfully. Three patients who were considered unresectble by other hospitals with CT were operated successfully with MI-3DVS. The other 3 patients' tumors were actually not able to be removed as pre-operative evaluation. Conclusion MI-3DVS plays an important role in diagnosis and assessment of resectability of pancreatic tumor.%目的 研究腹部医学图像三维可视化系统(MI-3DVS)在胰腺肿瘤诊断及可切除性评估中的价值.方法 2008年11月至2009年8月应用MI-3DVS对12例胰腺肿瘤患者的64排螺旋CT扫描数据进行三维重建,对胰腺肿瘤进行辅助诊断及可切除性评估,并与手术所见及病理检查结果进行对照.男性7例,女性5例,年龄14～83岁,平均45岁.其中胰腺癌4例、胰腺实性假乳头状瘤5例、浆液性囊腺瘤2例、胰腺囊肿(导管上皮乳头状增生)1例.结果 12例患者中,术前评估可切除的9例均成功切除肿瘤;2例术前评估不可切除,术中得到证实,仅行姑息手术;未手术1例.3例被外院判为不可切除的胰腺肿瘤患者,三维重建显示巨大肿瘤对相邻大血管为严重压迫,成功切除了肿瘤.结论 MI-3DVS重建对胰腺肿瘤的诊断和可切除性的评估有较高应用价值并具显著临床意义.
