Comparison of magnetic resonance imaging and spiral CT in the diagnosis of thyroid microcarcinoma / 中国医师进修杂志

Objective To study the diagnostic value of magnetic resonance imaging (MRI) and spiral CT in thyroid microcarcinoma (TMC), in order to improve the diagnostic accuracy of TMC. Methods The preoperative imaging manifestations of MRI and spiral CT in 68 TMC patients who were confirmed by surgical pathology were retrospectively analyzed, and the diagnostic accordance rates were compared between the independent and the combined diagnosis. Results The diagnostic accordance rates of MRI and spiral CT in TMC were 73.53%(50/68) and 66.18%(45/68). The diagnostic accordance of combined MRI and spiral CT in TMC was 88.24%(60/68). The diagnostic accordance rate of combined MRI and spiral CT was significantly higher than that of independent examine, and there was statistical difference (P0.05). Conclusions Spiral CT is superior to MRI in the micro-calcification detection, and MRI, with a high resolution of soft tissue, can display the lesions of surrounding tissue organs and neck lymph node metastasis better. The combined examine can increase the diagnostic accuracy of TMC.

The efficacy of PCI and IABP in the treatment of acute myocardial infarction complicated with cardiogenic shock / 中国介入心脏病学杂志

Objective To investigate the effect of percutaneous transluminal coronary angioplasty (PTCA) and stent implantation with intraaortic balloon pump (IABP) on immediate death rate and cardiac function of patients with acute myocardial infarction (AMI) complicated with cardiogenic shock.Methods Emergency coronary angiography was taken 0.5-32 h after the attack, and PTCA and stent implantation performed on infarction related artery (IRA), supported by IABP until patients′ complications improved. Myocardial echocardiography was taken 5 weeks after operation.Results Except for 4 patients who died of aggravated shock or cardiac failure, all the patients had IRA reperfusion. Twenty-four patients had stents implanted (85.71%). Mean time from attack to reperfusion was 8.6 h, and death rate in the period of 5 weeks was 31.25%. EF of the 22 patients who survived was 0.43～0.67.Conclusion PTCA and stent implantation supported by IABP can improve results of operation,increase reperfusion rate, decrease immediate death rate and improve cardiac function.
