Objective To investigate the effects of established swine acute myocardial infarction and following ventricular remodeling model by occluding Coronary with balloon. Methods Ten healthy Domestic swine are enrolled. Each swine's left anterior descending coronary artery was occluded for three hours by dilated balloon, and then reperfusion was performed. During the whole course of operation, the electro-cardiogram was monitored. B-ultrasound and single -photon emission computed tomography examination (SPECT) were performed to detect left ventricular end diastolic dimension, left ventricular tip wall thickness, left ventricular end diastolic volume and left ventricula ejection fraction before operation and one week, three month, six month after acute myocardial infarction. Results Five swine died during the period of opera-tion for lack of experience, the remains survived. Electrocardiogram revealed significant ST-elevation and Q-wave formation. B-untrasound and SPECT witnessed deteriorating left ventricular end diastolic dimension expansion, left ventricular tip wall thickness thinning, left ventricular end diastolic volume expansion and left ventricular ejection fraction depression. Conclusions Coronary artery occlusion by balloon can successfully establish acute myocardial infarction and following left ventricular remodeling models.

PurposeTo investigate whole-body magnetic resonance imaging in diagnosis of idiopathic inflammatory myopathy (IIM), and to guide clinical treatment.Materials and Methods Twenty-six patients clinically diagnosed IIM including 19 dermatomyositis and 7 polymyositis were analyzed retrospectively. Whole-body MRI was performed in all patients including whole-body coronal scan and axial scan of both sides of thigh. Short tau inversion recovery (STIR) sequences were used in the coronal scan and T1WI and fat-suppressed T2WI were performed in the axial scan. Ten healthy volunteers were recruited as control group. MRI findings were compared between the two groups.Results Whole body MRI showed that muscles were homogeneously low signal intensity in the control group. Imaging findings of the patients with IIM included muscle inflammation, fascitis, subcutaneous tissue edema, muscle atrophy and fatty infiltration. The most common distribution site of muscle inflammation of dermatomyositis patients was thigh (n=18), followed by gluteus (n=14), great psoas muscle (n=13), shoulder muscles (n=11), leg muscle (n=11), erector spinae (n=10) and neck muscles (n=9). Findings out of muscles included cavities in the both lungs, infarction in femurs and tibias, avascular necrosis of femoral head, adrenal mass and thyroid nodules. The most common distribution site of muscle inflammation of polymyositis was thigh (n=5), followed by gluteus (n=3), great psoas muscle (n=3), shoulder muscles (n=2), leg muscles (n=2), erector spinae (n=1) and neck muscles (n=1). Findings out of muscles included 1 case of infarction in femurs and tibias.Conclusion Whole-body MRI can not only comprehensively evaluate the activity of IIM but also detect complications such as bone infarction. It's a powerful tool for diagnosis, guiding treatment and monitoring of IIM.
