Objective To establish abdominal aortic dissection model in ApoE-/-mice, and to evaluate the ability of 7.0T MR to detect the abdominal aortic artery aneurysms in ApoE-/-mice in vivo. Methods ApoE-/-mice aged 10 months were infused with angiotensin Ⅱ with 14 days Osmotic minipump after 10 weeks of high lipid diet. Two different doses of angiotensin Ⅱ were given to mice, i.e. 1000 ng/(kg·min) and 500 ng/(kg·min), respectively. The contrast group was infused with saline water. The abdominal aortic artery was observed in vivo with MR before and within 14 days infusion. At last, the pathological changes of the abdominal artery were compared with MRI findings. Results After 6 or 7 days higher dose of angiotensin Ⅱ infusion, aortic dissection was seen. MR T2WI showed crescent-shaped high signal in the vessel wall of one side，the pathological study identified the hematoma between media and adventitia. Abdominal aortic dissection aneurysms were also found in the mice 13 or 14 days after lower dose of angiotensin Ⅱ infusion, which were consistent with pathological studies. Besides, the signal of the vessel wall was significantly higher in both T2WI and PDWI sequences. There was excellent agreement between MR and histopathology. 〖WTHZ〗 Conclusion Abdominal aortic dissection aneurysms model can be successfully established with different doses (1000 ng/(kg·min) and 500 ng/(kg·min)) of angiotensin Ⅱ infusion into ApoE-/-mice fed with high lipid diet. High-resolution MR is able to visualize the abdominal aortic dissection aneurysm formation in vivo.

Objective To investigate the value of high-dose dobutamine stress echocardiography combined with two-dimensional strain imaging in early diagnosis of coronary artery disease. Methods Highdose dobutamine stress echocardiography was performed to 28 patients with suspected coronary artery disease. All wall movements were observed during resting condition and at all stress levels,respectively;the peak systolic longitudinal strain in each endomyocardial segment of left ventricular was measured; the sensitivity and specificity between visual method and two-dimensional strain imaging in diagnosing myocardial ischemia with high-dose dobutamine stress echocardiography were compared. The average peak systolic longitudinal strain was calculated against control group, coronary artery disease group during ischemia segments and non-ischemia segments, and a comparison was made inside each group as well as against the other groups. The area under receiver operating characteristic curve of the peak systolic longitudinal strain was used to predict the sensitivity and the specificity of myocardial ischemia. Results With dobutamine dose of 40 μg·kg-1 · min-1 ,wall motion abnormalities were diagnosed in 6 patients (20 segments) through visual method, myocardial ischemia was found in 15 patients (148 segments) through computing the peak systolic longitudinal strain. Inside the coronary artery disease group during ischemic　segments,the majority of peak systolic longitudinal strain was significantly reduced ( P＜0.05) compared to the non-ischemic segments and the control group. In diagnosing myocardial ischemia in high-dose dobutamine stress echocardiography, the sensitivity of visual method and two-dimensional strain imaging were 35.3％ and 88.2％(P＜0.01), specificity 100％ and 100％(P＞0.05), and accuracy 60.7％ and 92.8％ (P＜0.01). The cutoff value of the peak systolic longitudinal strain was less than or equal to 14.9％, its sensitivity and specificity in predicting myocardial ischemia were 83.3％ and 91.7％,respectively. Conclusions High-dose dobutamine stress echocardiography combined with two-dimensional strain imaging can increase the sensitivity of detecting myocardial ischemia and detect concealed myocardial ischemia. High-dose dobutamine stress echocardiography combined with two-dimensional strain imaging can be used in early diagnosis of coronary artery disease.
