ABSTRACT
Objective To investigate the imaging features of solitary plasmacytoma of bone(SPB),to improve the ability of imaging diagnosis of SPB.Methods Retrospective analysis by surgery or biopsy pathology confirmed 16 cases of patients with SPB clinical and imaging data.Results All lesions were single.X-ray and CT scan showed swelling bone destruction,boundary more clearly,in all cases no periosteal reaction.Compared with the muscle signal,T1-weighted images showed equal or slightly lower signal,T2-weighted images showed high signal.All patients had no significant peritumoral edema in the bone marrow,but were seen varying degrees of soft tissue invasion.Enhanced MR scan,most cases showed significantly enhanced uniformity.Conclusions SPB presents osteolytic destruction,expansive growth and soft tissue mass without bone reaction and peritumoral edema.X-ray,CT and MR together might improve the diagnostic accuracy of SPB.
ABSTRACT
Objective To evaluate the effect of Diver CE aspiration thrombus catheter used in patients during the recovery of acute myocardial infarction (AMI) with percutaneous coronary intervention (PCI). Methods A total of 50 AMI patients were enrolled from January 2010 to December 2011. Twenty-ifve patients received PCI and used the Diver CE aspiration thrombus catheter (aspiration group);and the other 25 patients received routine PCI (routine PCI group). The basic characteristics, PCI characteristics, myocardial perfusion indexes and clinical data were compared and analyzed. Results There was no statistically difference between two groups in basic characteristics. Compared with the routine PCI group, higher rate of myocardial blush grade 3 but lower thrombus scores were found in the aspiration group. The incidence of no-lfow or slow-lfow were also lower in aspiration group (all P<0.05). The LVEF after 6 and 12 months were higher in the aspiration group (both P<0.05), no difference in MACE between the two groups. Conclusions Using the Diver CE thrombus aspiration in PCI is a simple and safe by method for treatment of acute myocardial infarction with high thrombosis burden. It can improve reperfusion decrease the rates of no-relfow on slow-relfow and can improve the long-term left ventricular function.
