99Tcm-环丙沙星显像检测重症急性胰腺炎继发感染的实验研究

Objective To evaluate the characteristics of 99Tcm-ciprofloxacin and explore its feasibility in early detection of secondary infectious foci of severe acute pancreatitis (SAP).Methods Ciprofloxacin was labeled with 99Tcm.The labeling efficiency and radiochemical purity of 99Tcm-ciprofloxacin were calculated and its biodistribution in normal pigs was measured.The recruited baby pigs were divided into three groups:normal control group (6), non-infected group (6) and infected group (16).370-400 MBq of 99Tcm-ciprofloxacin was injected into each pig intravenously.SPECT scanning was performed at 0.5, 1,2, 3, 4 and 6 h after administration.The differences of 99Tcm-ciprofloxacin uptake among groups were calculated and the tracer activity ratio of lesion-to-background was recorded at each time point.The diagnostic value of 99Tcm-ciprofloxacin SPECT imaging for the dectection of secondary infection of SAP was assessed using histopathological results as the gold standard.Variance analysis and least significant difference test were used to analyze the data.Results Both the labehing efficiency and radiochemical purity of 99Tcm-ciprofloxacin were over 90% within 6 h.Organs with rich blood supply, such as kidney, liver and spleen were the target organs for the accumulation of 99Tcm-ciprofloxacin; while no significant uptake was found in gastrointestinal tract or normal pancreas tissue of SAP.Rapid plasma clearance and renal excretion were observed.In the infected group, the lesion was visualized at 1 h after administration.The highest radioactivity ratio of lesion-to-background (3.36 ± 0.33) was at 3 h after administration, which was significantly higher than that of the other time point ( F =99.570, P ＜0.001 ).The sensitivity, specificity, positive and negative predictive values, Youden's index (YI) and Kappa value of 99Tc%ciprofloxacin imaging were 88.2% (15/17), 83.3% (5/6), 93.8% ( 15/16), 71.4% (5/7), 0.715 and 0.667 respectively.Conclusions The biodistribution of99Tcm-ciprofloxacin is suitable for imaging infectious focus of SAP.The optimal imaging time for the detection of secondary infection of SAP is 3 h after administration, with high sensitivity and specificity.     

呼吸导航与心电触发对兔肝脏磁共振成像应用比较

目的 比较1.5T磁共振扫描仪(Avanto)在呼吸导航技术和心电触发技术配合下对兔肝脏扫描成像质量的优劣.方法 分别应用呼吸导航技术和心电触发技术配合1.5T磁共振扫描仪对10只新西兰大白兔进行肝脏扫描,在保证图像平均信噪比(SNR)在1±0.1状态下,比较每种检查图像的优劣.扫描序列分别为TSE序列T_1加权、脂肪抑制T_1加权平扫及增强、T_2加权和脂肪抑制质子加权.结果 在心电触发配合下各个序列扫描图像质量均优于在呼吸导航下扫描所得图像,主要表现为前者受运动伪影干扰明显少于后者.结论 在SNR为1±0.1状态下.1.5T磁共振采用心电触发技术扫描兔肝脏所得图像质量优于采用呼吸导航时相同序列扫描所得图像,原因可能和兔的生理特点及2种不同门控方法的敏感度差异有关.     

三例多脾综合征患者的CT、MRI表现

多脾综合征(polysplenia syndrome)是一种少见的先天性多系统畸形组成的综合征,主要为多脾、心血管及其他内脏发育异常的联合畸形.以往多在尸检或手术时发现,现在由影像检杳发现的报道逐渐增多.
