The best quality of MRS is that the MRS is the only noninvasive and in vivo means in detecting the changes in metabolism state and special biochemical compounds in living animal and human body, and that make it possible for us to observe the physiological and biochemical characteristic of brain neoplasma ,and the development of neoplasma.

脑肿瘤是较为常见的肿瘤，其发病率占全身肿瘤的1.8％，其中以脑胶质瘤为最多，占43.7％，脑肿瘤的诊断及治疗一直是临床及基础研究的难点及热点，为了更好的了解胶质瘤的生物学特征，寻找有效的治疗方法，人们一直在寻求建立稳定安全的脑动物模型，大鼠C6胶质瘤具有与人脑胶质瘤相似的生物学特征，且模型较为稳定，被广泛用于肿瘤生物学及实验性治疗的研究中。

Later, under the untypical parasternal four-chamber view which can thoroughly display the ostium of coronary sinus, the catheter was promoted further to the ostium of coronary venous sinus. Then the echocardiography technician adjusted the transducer of TTE in order to thoroughly confirm the position of the catheter tip. After confirming the position of catheter tip in the coronary venous sinus, the operator inserted the catheter into the coronary venous sinus for 3～4 mm farther. It was noted that if resistance was encountered by operator, the operation must be stopped, which was the same as x-ray fluroscopy as image guiding. TTE guiding His bundle elactric cahteter、high right atrium electric cahteter and right ventricular electric catheter in site: It is difficult using TTE singly since there are too many crossroads in inferior venous.

本研究结果显示，(1)单独应用TTE作为影像学引导进行冠状窦电极导管置放的成功率为93.8％～96.7％，并且应用TTE作为影像学引导放置专用冠状窦电极导管和普通电极导管的成功率和放置时间在统计学上无显著差异；(2)TTE作为影像学引导，除过度肥胖患者外，可完全替代X线引导进行冠状窦电极导管置放，包括鞘管和扩张管的放置、指引导丝在静脉而非动脉内的证实均可由TTE完成引导，且较X线C型臂有一定优越性；(3)TTE结合普通X线胃肠透视机作为影像学导引，可顺利完成心内电生理检查时导管的安全到位，而不需昂贵的X线C型臂，可将心内电生理检查扩大到广大的基层医院；(4)TTE较X线更易和更早期发现介入治疗的并发症如急性心包填塞等，对并发症的防治甚至挽救病人的生命至为重要；(5)动物实验研究表明，TEE可引导射频导管消融术时大头电极导管成功到位。
