查询词典 helical

Methods: Basing on the air pressure enema examination and CT angiography technology,we used 64-slices helical CT to scan for tracking from the 9th thoracic vertebra to the middle part of femur in cross section along the arterial and venous phases continuously.

基于空气灌肠检查及CTA血管造影技术，64层螺旋CT对胸9至股骨中段沿横断面在动脉期及静脉期连续跟踪扫描。

Results: Among 53 positive cases , single nodus was found in 47 cases, with 21 in left lung and 26 in right lung. The diameter ranged from 0.5cm to 3.0cm. Rugged edge and vascular figure were clearer in helical than in routine scan. Double noduses were found in 2 cases and all proved to be benign later , with one as tuberculosis and the other as nonspecific infection. Multiple noduses of both lungs were found in 4, with 3 as carcinomatous metastasis and 1 as tuberculosis. Among 100 controls in whom no nodus was found in routine CT scan ,a nodus (0.5cm) was found in 92 cases to have health examination and 2 was found in 8 cases with cancer (6 with esophagus cancer and 2 with lung cancer ).

结果：阳性者53例中，单个结节47例（左肺21例右肺26例），结节直径（0.5cm-3.0cm），比常规扫描更能检出结节边缘凹凸不平及肿瘤供血血管。2个结节2例均为良性（一例手术病理证实为结核，1例抗炎治疗后吸收痊愈），双肺多发性结节4例（3例为转移瘤，一例为结核），常规扫描无阳性发现者100例做三维重建，其中92例作健康体检者检出一个结节（0.5cm）；8例有癌性病史患者（食道癌6例肺癌2例），检出两例有结节。
