本文对30例肝脏肿瘤的患者进行 CT-AP(CT during Arterial Portography)的检查结果进行了分析,并与超声和 MRI 进行了对比,认为 CT-AP 在病灶显示率和门脉栓子显示率均优于超声和MRI,应作为选择肝脏肿瘤治疗方法的必要检查。在本研究中,对国产离子型造影剂与进口非离子型造影剂进行了对比,认为在 CT-AP 检查上两者无明显差异,为了降低 CT-AP 的检查费用提供了理论基础。并且利用4F 导管经肱动脉穿刺进行 CT-AP 检查,使患者在门诊就可以接受 CT-AP 检查,扩大了CT-AP 的检查范围。 In this paper, the CT-AP (CT Arterial Portography) results were analyzed in 30 patients with liver tumors, and compared with ultrasound and MRI, CT-AP in the lesion display rate and portal embolus display rate Better than ultrasound and MRI should be used as a necessary check for the selection of hepatic tumor therapy. In this study, we compared domestic ionic contrast agents with imported non-ionic contrast agents and found that there was no significant difference between CT-AP examinations. This provided a theoretical basis for reducing CT-AP examination costs. In addition, CT-AP was performed via a radial artery puncture using a 4F catheter, allowing the patient to undergo CT-AP examination in the outpatient clinic, which expanded the scope of CT-AP examination.
