Contrast enhanced CT was performed in seven patients with pancreatic disease (chronic pancreatitis, n = 3; pancreatic head cancer, n = 2; mucin-producing pancreatic tumor, n = 2) who showed dilation of the main pancreatic duct (MPD) Minimum intensity projection (Min-IP) images of the pancreas were obtained using multi-projection volume reconstruction (MPVR) software by selecting an oblique slab that contained the entire MPD. Curved reformation (CR) images were obtained using multiplanar reformation (MPR) software by tracing the MPD on the Min-IP image. Both Min-IP images and CR images clearly showed the dilated main pancreatic duct in all seven patients. In three of the seven, obstruction of the MPD in the pancreatic head and the cause of obstruction (tumor mass, n = 2; caliculus, n = 1) were also clearly seen. Min-IP and CR images seem to be useful for the diagnosis of pancreatic diseases.
对7例患有胰腺疾病（慢性胰腺炎3例；胰头癌2例；黏液性胰腺肿瘤2例）且主胰管（MPD）扩张的患者进行了对比增强CT检查。通过选择包含整个MPD的斜切片，使用多平面容积重建（MPVR）软件获得胰腺的最小强度投影（Min-IP）图像。通过在Min-IP图像上追踪MPD，使用多平面重组（MPR）软件获得曲面重组（CR）图像。Min-IP图像和CR图像在所有7例患者中均清晰显示了扩张的主胰管。在这7例中的3例中，还清晰可见胰头处MPD的梗阻及梗阻原因（肿瘤块，2例；结石，1例）。Min-IP和CR图像似乎对胰腺疾病的诊断有用。
