摘要

A few studies have been reported that CT cine viewing on the CRT is superior to film-based viewing of CT images (Seltzer et al., Radiology 197 (1994) 119; Bonaldi et al., Am. J. Roentgenol. 170 (1998) 373; Tillich et al., Am. J. Roentgenol. 169 (1997) 1611). The purpose of our study is to know how to use cine viewing of abdominal CT. Thirty CT studies on the abdomen with both precontrast and postcontrast images were examined. The suitable rate of cine viewing ranged from 1 to 6 frames per second according to the size, the contrast and the complexity of the anatomical structures, and the slice thickness. For small or complex structures, checking each image might be required to know the full detail of them. Positional sorting among multiphase images, which is followed by consecutive display of a precontrast image, postcontrast early and late phase images at one position and so on, is useful to see the dynamic pattern of enhancement of the anatomical structures. However, there was no significant difference between cine viewing and film-based viewing concerning both the detectability of the anatomical structures and the conspicuity of enhancement of the liver and the pancreas, so that cine viewing might be an alternative to film-based viewing for CT diagnosis of the abdomen.

Roentgenol。170（1998））。 373; Tillich等，Am.J.Roentgenol.169（1997）1611）。我们研究的目的是要知道如何使用电影方式查看腹部CT。进行了30例腹部CT检查，同时显示了造影前和造影后的图像。根据大小，解剖结构的对比度和复杂性以及切片厚度，合适的电影观看速率范围为每秒1到6帧。对于小型或复杂的结构，可能需要检查每个图像以了解它们的完整细节。在多相图像之间进行位置排序，随后在一个位置上连续显示对比前图像，对比后早期和后期图像等，对于查看增强解剖结构的动态模式很有用。但是，在电影观看和基于胶片的观看之间，在解剖结构的可检测性以及肝脏和胰腺增强的显着性方面都没有显着差异，因此，对于CT胶片观看而言，电影观看可能是一种替代方法诊断腹部。
