摘要

目的：

探讨超声仿真结肠成像(ultrasound colonography，USC)显示正常结直肠腔的可行性和成像质量。

方法：

8例健康志愿者行严格肠道准备后，经二维超声评估各肠段(盲肠-升结肠、横结肠、降结肠、乙状结肠、直肠)，对肠腔清洁度良好、无肠气及肠腔充盈良好的肠段施行USC检查，统计USC在各肠段的可施行率及成像质量。

结果：

USC可施行率：盲肠-升结肠4例(50.00%)，横结肠3例(37.50%)，降结肠、乙状结肠和直肠均8例(100%)。USC成像质量(1级：差；2级：欠佳；3级：良好)结果显示，盲肠-降结肠1级1例(25.00%)、2级2例(50.00%)、3级1例(25.00%)；3例横结肠(100%)达2级；降结肠1级0例、2级6例(75.00%)、3级2例(25.00%)；8例(100%)乙状结肠及8例(100%)直肠达3级。

结论：

USC在乙状结肠、直肠的可施行率高，成像质量良好；在降结肠的可施行率高，但成像质量欠佳；在盲肠-升结肠、横结肠的可施行率低，成像质量较差。

Abstract

Objective:

To investigate the feasibility of ultrasound colonography (USC) in depicting healthy colon and rectum.

Methods:

Standard bowel preparation was performed on eight healthy volunteers. Ultrasonography was used to observe the retained fecal material

the colonic gas and the luminal distention of different segments of colon and rectum (cecal-ascending

transverse colon

descending colon

sigmoid colon and rectum). The segments that met the following requirements were allowed to undergo USC: without retained fecal material or gas

and with well distention. The feasibility and imaging quality (grade 1 poor;grade 2moderate; grade 3

well) of USC in different segments were evaluated.

Results:

Four (50.00%) cecal-ascending clons

3 (37.50%) transverse colons

8 (100%) descending colons

sigmoid colon and rectum were performed USC examinations

respectively. For USC image quality

1 (25.00%)

2 (50.00%) and 1 (25.00%) cecal-ascending colons were ranked as grade 1

grade 2 and grade 3

respectively; 3 (100%) transverse colons were ranked as grade 2; 6 (75.00%) and 2 (25.00%) descending colons were ranked as grade 2 and grade 3

respectively; 8 (100%) sigmoid colons and rectums were ranked as grade 3.

Conclusion:

Sigmoid colon and rectum are well depicted while most descending colons are moderately depicted. Only some of cecal-ascending and transverse colons are able to undergo USC

and show various conspicuities.
