An in column injection technique (ICIT) that introduces the sample directly into the retention gap of the column is described in this paper. A 15cm long fused silica capillary tubing which was connected to the syringe needle through a mini two way connector(SGE, Australia) was used as the injection needle for the introduction of sample into the section of retention gap inside the oven. The injector temperature control was shut off to avoid the evaporation and bubble formation inside the capillary needle during...

An in column injection technique (ICIT) that introduces the sample directly into the retention gap of the column is described in this paper. A 15cm long fused silica capillary tubing which was connected to the syringe needle through a mini two way connector(SGE, Australia) was used as the injection needle for the introduction of sample into the section of retention gap inside the oven. The injector temperature control was shut off to avoid the evaporation and bubble formation inside the capillary needle during the time of injection. The function of the injector is actually the needle guide for the capillary column. The sample evaporation, solute focusing and separation were completed within the single oven in one temperature programming. The error of sampling accuracy and reproducibility was less than ±1 5% with manual injection. Sample discrimination and the final separation results of the ICIT were the same or even better than the cold on column injection technique, while the design of the injector was greatly simplified. Factors affecting the performance of the injection were studied systematically. The depth of the needle tip within the oven should be more than 0 5cm to avoid cold spot area. The boiling point of the solvent used has little effect on the performance as long as the boiling point of the solute is 50℃ higher than that of the solvent. We did not observe the influence of injection volume, at 2 20μL range, on the separation and quantitation. The analysis of real life wax samples was demonstrated. Experimental results proved that this technique is reliable in performance and simple to operate for high temperature capillary GC.

Objective To evaluate the magnetic resonance angiography(MRA) in senile lower extremity arterial disease and to compare the diagnostic value of two dimensional time of flight(2D TOF) with three dimensional contrast enhancement(3D CE) technique. Methods Seventy patients with a mean age of 75 years underwent MRA for suspected acute or chronic lower extremity arterial disease. MRA was performed with a 1 5 T MR scanner and Gd DTPA was used by manual injection in 3D CE MRA. Among 52 patients examined with 2D TOF MRA, 18 of them underwent an additional 3D CE MRA, 32 patients took Doppler ultrasound examination, and 4 patients received emergency operation. Results In all 70 patients, 52 showed atherosclerotic stenosis disease, 17 atherosclerotic occlusive disease (4 of them were verified by emergency operation) and one patient atherosclerosis with aneurysmal dilatation. A total of 997 vessel segments were shown on MRA images and 600 of them were abnormal including 486(81%) mild to moderate stenoses, 114(19%) severe stenoses and 451 curved arterial segments. In 32 patients who underwent Doppler ultrasound, the diagnosis and its grading based on MRA was well correlated with that from Doppler ultrasound (coincidence rate was 91% and 96% respectively). A total of 764 suprapopliteal and 125 infrapopliteal arteries were depicted by 2D TOF MRA (visibility was 99% and 40% respectively). In 18 patients who received additional 3D CE MRA, totally 306 arteries were depicted on MRA (visibility 100%). Doppler ultrasound showed 40 segments with arterial calcification and 32 atherosclerotic plaques. Conclusions MRA is quite useful in detecting lower extremity arterial disease because of its noninvasion and convenience. The results derived from MRA are well correlated with that of Doppler ultrasound and clinical outcome. 3D MRA is superior to 2D TOF MRA in image quality, accuracy and time efficiency and is best for emergency case. Pitfalls of MRA such as overestimation in the severity of the disease and the long scanning time of 2D TOF must be taken into consideration .

目的 探讨磁共振血管造影 (MRA)在老年人下肢动脉病变诊断中的应用价值。 方法 采用 1 5T超导MR扫描对疑急、慢性下肢动脉病变的老年患者 70例进行检查 ,平扫用二维时飞法序列 (2D TOF) 5 2例、2D TOF加三维增强序列 (3D CE) 18例。 32例行彩色多普勒超声 (彩超 )检查 ,4例急诊手术。 结果  70例老年患者经MRA诊断 ,动脉硬化伴狭窄 5 2例 ,动脉硬化闭塞症 17例 ,动脉瘤样扩张 1例。MRA共显示血管 997条 ,其中 5 2例 2D TOF平扫显示腹主动脉下段、髂总、髂外、髂内、股、动脉及小腿动脉 ,平均显示率为 91% ;18例增强扫描上述血管显示率 10 0 %。 70例显示动脉狭窄共 6 0 0条 ,其中轻、中度动脉狭窄 4 86条 ,占 81% ;重度狭窄 114条 ,占 19%。 32例老年患者经彩超检查 ,两者诊断符合率为 91% ,病变程度符合率为 96 %。彩超显示血管壁钙化 4 0条 ,粥样斑块 32条。 结论 MRA与临床、手术、彩超有良好的相关性 ,是下肢动脉病变的有效检查方法之一。 2D TOF有对病变“高估”、检查时间较长的不足。

Objective:To evaluate the clinical value of high pressure injector in application of the perfusion MRI and angiography. WTHZ Methods: WTBZ 30 cases of brain tumor were performed perfusion MRI,28 of vascular disease performed routine enhanced MRI and 5 of coronary heart disease performed myocardium perfusion imaging.During the procedure a Medrad Spectris MR injector was used at bolus injection of contrast agent via upper extremity.According to the size of vessel and lesion,preset was the flow speed,flow amount and injection time,and the area of the interest was subsequently scanned with short or delay time using corresponding programs. As a control,12 other cases of brain tumor were performed perfusion MRI with manual injection and their time intensity curves were comparatively analyzed. WTHZ Results: WTBZ Of 42 cases with brain tumors,30 were proved by operation and pathology,6 by surgical results in another hospital and 6 by biopsy. 28 cases of vascular diseases were proved by IADSA.The MR angiograms of vascular diseases in 28 and myocardium perfusion MR images in 5 reached the diagnostic standard. The curves of brain blood perfusion in the group with high pressure injector was superior to those with manual injection.Conclusion:The pressure injector can maintain the flow speed and the concentration of the contrast agent to accomplish the accurate perfusion.According to the program of the perfusion imaging and angiography being performed,the injection rate and time can also be adjusted to do precisely the exams mentioned previously.
