objective to evaluate the role of mr perfusion weighted imaging in preoperation diagnosis of meningiomas.methods mr perfusion weighted images was performed in 47 patients with meningiomas followed by conventional imaging.results the mean rcbv values of angioblastic was the highest in the parenchyma of tumor.the mean rcbv values of malignant group was the lowest.the biggest mean rcbv values among different type meningiomas was statistically significant.the biggest mean rcbv values between benign and malignant group meningiomas was statistically significant,but not in the peri-tumor edema.conclusion the rcbv values were useful in the preoperative differentiation diagnosis of different types of meningiomas.those in the peri-tumor edema were useless in the preoperative differentiation diagnosis of different types of meningiomas.

目的 探讨磁共振灌注成像技术对脑膜瘤术前分型及良恶性鉴别的临床应用价值。方法对47例脑膜瘤病人行mr灌注成像检查，对5种亚型的良性脑膜瘤的mr灌注成像进行分析，并与非典型性及恶性脑膜瘤进行比较。结果血管瘤型脑膜瘤实质部分的rcbv值均数最高，恶性组脑膜瘤的rcbv值均数最低。各亚型间瘤体实质最大rcbv值均数间差异有统计学意义(p＜0.05)，良恶性脑膜瘤实质部分最大rcbv值均数间差异有统计学意义(p＜0.05)。瘤周水肿区的rcbv值均数间差异无统计学意义(p＞0.05)。结论 rcbv值对脑膜瘤术前分型及良恶性鉴别有所帮助，而瘤周水肿区的rcbv值对脑膜瘤分型及良恶性鉴别未显示临床实用价值。

Results In vitro recovery of the probe was mainly influenced by the perfusion rate. When the perfusion rate was set at 1.0μL/min, in vitro and in vivo recoveries of the probe were 50.16±2.34% and 14.096±0.58%, respectively. The enhancement indexes for 3%, 5% mentha oil were 3.8 and 17.6, respectively. The enhancement indexes were 9.2 and 24.8, for 3% and 5% of Azone, respectively. Conclusion The steady sate flux of meloxicam in rats is significantly improved by enhancer mentha oil and azone.

结果： 在实验条件下微渗析探针的体外回收率主要受灌注液流速的影响，为（50.16±2.34）%；反向渗析法测得探针的在体回收率为（14.096±0.58）%；MO的体积分数为3%和5%时，增渗倍数分别为3.8，17.6；azone的体积分数为3%和5%，增渗倍数分别为9.2，24.8；结论：不同体积分数的MO和azone均可显著增加美洛昔康经皮渗透稳态流量，azone的体积分数为5%时，大鼠角质层的屏障作用可能受到了较大程度的破坏。

As a supplement of conventional CT, CT perfusion imaging can reveal the perfusion informations of tissue or organs, such as hemodynamics, microcirculation status. It is helpful not only in finding morphologic changes, but also in providing functional and metabolizable information about the circulation parameters of hepatic diseases. So, it is valid for studying liver disorders by providing functional information, especial for the differential diagnosis and assessment for therapeutic response.

作为常规CT的一种补充，它能提供组织器官微循环状况、血流动力学变化等其它灌注参数，对肝脏病变除了能显示解剖形态学改变，还能了解血流动力学状态等反映功能、代谢变化的信息，在肝脏疾病的影像诊断与鉴别诊断等方面具有重要的作用，特别是对各种治疗方法的疗效评估及监测具有指导意义。

The same procedure was carried out 14 days later. Results The temperature of inferior segment of esophagus was significantly increased at 60min. The temperature of physic liquor was significant higher than that of perfusion. The temperature of perfusion was becoming significantly increased at 5min (P.05). The WBC, PLT, ALT, AST, Cr and CO2CP of preoperative and postoperative had no significant changes. Only lightly peritoneum dropsy and infiltrate slight phlegmasia were observed postoperatively and 14 days later. There were no significant differences among groups.
