Super in the stomach to the mezzanine has applied to the value

目的：探讨彩超在腹主动脉夹层瘤的诊断中的价值。方法：将20例通过彩超诊断为腹主动脉夹层瘤的患者，再经CT／MRI证实其正确性。结果：腹主动脉夹层瘤的彩超影像学表现为：腹主动脉管径增宽：2．5～3．5cm者9例，3．5～4．5cm者7例，超过4．5cm者4例；其中部分剥离17例，环形剥离3例。20倒患者均可见到双层管壁。内膜漂浮运动：腹主动脉长轴切面上可见有细而弱的回声光带，光带位置随心动周期而改变。真假腔：假腔的宽度0．4～2．8cm，真假腔均在心缩期变宽，在心舒期变窄。在夹层破口处见血栓形成6例，云雾状回声8例。与CT／MRI符合率为100％。结论：彩超可以作为诊断腹主动脉夹层瘤的常规检查，只要掌握其影像学特点，就能反时正确诊断腹主动脉夹层瘤。

Objective：to pass in the stomach to sections in the diagnosis of adenoma, methods： to pass 20 cases with the diagnosis for stomach to sections of the patient has to verify its validity by the ct mri. the stomach to sections of the image has to learn to behave to your ： to increased by 2. 5-3. ,5 is plumbing 9 cases, the 3.5 - 4.5 the example, more than 4. 5 cm in the case of divesting of 27 cases, the circular divesting 3. 20 patient would see double, the movement of the floating ： to the abdomen surface can see a long thin and feeble echo of a position to the heart stood still cycle and change, what＇s the width of the lumen ： a ratio exceeding 0.4-2.8cm heart of the beginning and then narrows my period, in the mezzanine broken the clot formed see six cases, the clouds with the 8 and mri in at 100% ct. Conclusion： the super can be used as a diagnosis stomach to sections of the regular inspection has a vocabulary of its intervertebral, in order to correct in his warts vignette
