B超、CT对于阑尾周围脓肿的临床影像学特征差异

The difference of clinical imaging features of periappendiceal abscess under B ultrasound and CT

目的探讨B超、CT对于阑尾周围脓肿的临床影像学特征差异。方法收集天津市南开医院诊断为阑尾周围脓肿的患者50例,所有患者均有明确的病理结果标本,入院后接受B超和CT检查。分析阑尾周围脓肿的CT影像学特征;对比B超和CT对诊断阑尾周围脓肿诊断的正确率。结果 (1)阑尾周围脓肿的CT影像学特征中"增强壁明显环形强化"百分率为80.0%,明显高于其他特征,差异有统计学意义(P<0.05)。(2)B超诊断阑尾周围脓肿的诊断正确率为90.0%,CT为98.0%,差异有统计学意义(P<0.05)。结论相对于B超,CT诊断阑尾周围脓肿的正确率高,临床影像学特征中以"增强壁明显环形强化"多见,可以作为诊断阑尾周围脓肿的首选检查方法。

Objective To investigate the difference of clinical imaging features of periappendiceal abscess under B ultrasound and CT. Methods 50 cases of periappendiceal abscess diagnosed in Tianjin Nankai Hospital were collected. All patients had definite pathological results,and received B ultrasound and CT examination after admission. The CT imaging features of periappendiceal abscess were analyzed,the diagnostic accuracy by B ultrasound and CT of periappendiceal abscess were compared. Results（1） In the CT imaging features of the abscess around the appendix, the percentage of ＂enhanced wall ring enhancement＂ with 80.0% was significantly higher than the other features,the differences were statistically significant（P0.05）.（2） The diagnostic accuracy of periappendiceal abscess by B ultrasound and CT were90.0% and 98.0%,the difference was statistically significant（P 0.05）. Conclusion Compared with B ultrasound,the diagnostic accuracy rate of periappendiceal abscess by CT is high,and the clinical feature of imaging is ＂enhanced wall ring enhancement＂,which can be used as the first method of examination for the diagnosis of periappendiceal abscess.
