目的探讨多层螺旋CT(MSCT)肺部血管造影在临床的应用价值。方法对68例肺部肿瘤及其它原因造成的大咯血患者采用16层螺旋CT行平扫和增强扫描,原始图像用容积显示(VR)、多平面重组(MPR)、最大密度投影(MIP)、曲面重建(CPR)进行重建,观察肺部病变血管来源、数目及形态。结果68例中(2例失败),肺部病变由支气管动脉供血者60例,肋间动脉供血者8例,胸廓内动脉供血者5例,左锁骨下动脉供血者6例,右膈下动脉供血者5例,腹腔干动脉供血者3例,右肾动脉供血者1例。单支血管供血者50例,2支血管供血者10例,3支血管供血者6例。55例供血血管呈丛状,8例走行迂曲,2例网状,1例动脉瘤形成。结论MSCT能全面的多方位清晰地显示肺内病变的供血血管,为临床治疗提供可靠的依据。
Objective To investigate the clinical value of multislice spiral CT (MSCT) pulmonary angiography. Methods Sixty-six patients with massive hemoptysis caused by pulmonary tumors and other causes underwent 16-slice spiral CT scan with enhanced volume scan (VR), multiplanar reconstruction (MPR), maximum density projection (MIP) Surface Reconstruction (CPR) was reconstructed to observe the source, number and morphology of pulmonary lesions. Results Sixty-eight patients (two failed), 60 patients with pulmonary lesions by bronchial artery, 8 patients with intercostal artery blood supply, 5 patients with thoracic artery blood supply, 6 patients with left subclavian artery blood supply, 6 patients with right subcapsular artery 5 cases of donors, 3 cases of peritoneal artery blood supply, 1 case of right renal artery. 50 cases of single vessel blood supply, 2 cases of vascular blood supply in 10 cases, 3 cases of vascular blood supply in 6 cases. 55 cases of blood vessels were plexiform, tortuous walking in 8 cases, 2 cases of reticular, 1 cases of aneurysm formation. Conclusion MSCT can comprehensively display the blood supply vessels of lung lesions in multiple directions clearly and provide a reliable basis for clinical treatment.
