Lack of a suitable oral contrast agent is the major drawback of abdominal MR imag-ing. FAC(Ferric ammonium citrat) was chosen to use as MR oral contrast agent.Test tube,animal ex-periment and clinical study were done to resolve a series of issues,including relaxation enhancing charac-teristics,the most appropriate concentration and clinical effectiveness of FAC. FAC demonstrates strong relaxation enhancing effect.At low concentration,the signal intensity increases with concentration due to predominance of T_1 shortening。At high concentration,the signal intensity decreases with increase in concentration due to predominance of T_2 shortening. The most appropriate concentration for FAC is 2.1mmol/L, with which the signal intensity of gastro-intestinal tract can be properly enhanced both on T_1 and T_2 weighted images.Orally administered FAC can well mark the gastrointestinal tract and im-prove delineation of adjacent normal and abnormal structures。The best result was abtained for the group using hypotonic technique,in which the delineation of the left lobe of the liver, all parts of the pancreas and the lowest part of the common bile duct are all significantly improved compared to the plain-scan group.Therefore,FAC is an effective, inexpensive oral MR contrast agent with no side effects.

缺乏一种理想的口服造影剂已成为腹部MRI发展中的一大障碍。笔者选用枸橼酸铁铵(FAC)作为MR口服造影剂,对其作用机理、增强规律、最佳浓度、造影方法、临床效果等问题进行了试管、动物实验和临床对照研究。FAC具有较强的弛豫增强作用,低浓度时,以缩短T_1为主,信号强度随浓度升高而增高;高浓度时,以缩短T_2为主,信号强度随浓度升高而降低。当FAC浓度为2.1mmol/L时,T_1W和T_2W像均得到满意的对比增强,故为最佳浓度。FAC口服造影可以标记胃肠道、提高邻近正常结构和病灶的解剖分辨率。造影时配合应用胃肠道松弛剂效果更好,低张造影组肝左叶、胰腺各段及胆总管下端的分辨效果明显优于平扫组。FAC具有价格低廉、无毒副作用、造影效果良好等优点,是较理想的MR口服造影剂。

new parallel scan structure is proposed. BALLAST algorithm is used to select the best scan flip-flops.Each scan group is selected in turn by decoder so that storage elements in each scan group can be controlled and observed in parallel. The total test generation and response time is K times faster than that of serial scan structure (K is the maximum degree of parallelism),while the hardware overhead required is much lower than those of multiple scan-path design and traditional...

提出了一种新的并行扫描结构。扫描触发器的选择采用BALLAST算法。该结构采用译码的方式依次选通每个扫描小组,使得扫描小组中的存储元件并行地控制和观测。测试产生和响应时间比串行扫描法快K倍(K为并行度),而硬件耗费比多链扫描法和传统的并行扫描结构小很多。

Objective To investigate CT features and the staging of the primary ovarian malignancy. Materials and Methods CT scanning, including pelvic scanning in 28 cases and total abdominal scanning in 44 cases, was performed in 72 patients before primary operation. CT findings were analyzed. CT staging in total abdominal scanning group was made and the CT findings were compared with operative results. Results Primary ovarian malignancy carried certain CT features. The preoperative diagnostic and staging accuracy was 96% and 89%, respectively, with the staging accuracy for stage Ⅲ patients being 91%. The detecting rate for the implantation in peritoneal cavity, greater omentum and parietal peritoneum was 73%, 77% and 81%, respectively.Conclusion CT scan has a high accuracy in diagnosing ovarian malignancy. CT scan is very correct for staging Ⅲ although it has only moderate accuracy in overall tumor staging. In detecting disseminated lesions in abdominal or pelvic cavity CT still has some limitations.
