目的探讨多层螺旋CT在肺动脉栓塞中的诊断价值。方法 16例肺动脉栓塞患者均使用多层螺旋CT行平扫以及造影增强扫描,采集图像。结果图像显示患者有栓塞肺动脉98支,其中肺动脉干及左、右肺动脉4支,叶肺动脉26支,段肺动脉28支以及亚段肺动脉40支;直接征象为中心型充盈缺损有7支,占7.1%,偏心型充盈缺损有79支,占80.6%,附壁环型充盈缺损有8支,占8.2%,闭塞型充盈缺损有4支,占4.1%;间接征象为双肺见斑片状渗出灶及实变影2例,纤维条索影11例,伴胸腔少量积液3例,患者的间接征象表现为肺灌注不均。结论多层螺旋CT在肺动脉栓塞的诊断中效果显著,同时具有快速、有效及无创伤等特点,在临床诊断中具有重要意义。
Objective To investigate the diagnostic value of multislice spiral CT in pulmonary embolism. Methods Sixteen patients with pulmonary embolism were scanned with multi-slice spiral CT and contrast enhanced scan to collect the images. Results The images showed that there were 98 embolized pulmonary arteries, including 4 pulmonary artery and left and right pulmonary arteries, 26 pulmonary arteries, 28 pulmonary arteries and 40 pulmonary arteries. The direct signs were central filling defects, accounting for 7.1 %, Eccentric filling defects in 79, accounting for 80.6%, 8 cases of pericardial ring filling defect, accounting for 8.2%, occlusive filling defects in 4, accounting for 4.1%; indirect signs of lung see patchy seepage In 2 cases, the focus of the stove and the real shadow, 11 cases of fibrous cord cable, 3 cases with small pleural effusion, the patient’s indirect signs of lung perfusion showed uneven. Conclusions Multi-slice spiral CT is effective in the diagnosis of pulmonary embolism and has the characteristics of rapid, effective and non-invasive treatment, which is of great significance in clinical diagnosis.
