目的研究在肺孤立性结节病症的诊断中,64排螺旋CT多平面重建所起到的诊断应用价值。方法对42例肺孤立性结节患者给予64排螺旋CT多平面重建进行检查诊断,首先采用仰卧位的姿势,头部先进,并根据扫描的预设范围从患者的肺尖部开始扫描,一直到肺底部,并根据计算机处理手段,将原有值改为层厚1 mm和层距1 mm,再次对薄层扫描的图像采用从上而下的方式进行筛查,并对结节进行精准定位,用软件进行多平面重建,以形成立体影像,最后进行电脑估测。结果运用64排螺旋CT能够对直径>2 mm的结节进行排查,但是一旦直径<4 mm,进行多平面重建后,密度以及标准会存在差异性。结论将64排螺旋CT多平面重建应用于肺孤立性结节病症的诊断中,具有显著的临床价值,在未进行手术时,可以以此数据为参照。
Objective To study the diagnostic value of multi-planar reconstruction with 64-slice spiral CT in the diagnosis of solitary pulmonary nodules. Methods Twenty-four patients with solitary pulmonary nodules were examined by multi-planar reconstruction with 64-slice spiral CT. The patients were first trained in supine position with advanced head and scanned from the patient’s lung apex according to the preset scan range To the bottom of the lungs, and according to computer processing means, the original value was changed to a layer thickness of 1 mm and the layer spacing of 1 mm, again using the top-down scanning of the thin-layer image screening and nodule precision Positioning, using software for multi-plane reconstruction to form a three-dimensional images, the final computer evaluation. Results With 64-slice spiral CT, nodules> 2 mm in diameter can be examined, but once the diameter is less than 4 mm, there will be differences in density and standard after multiplanar reconstruction. Conclusion The application of 64-slice spiral CT multiplanar reconstruction in the diagnosis of solitary pulmonary nodules has significant clinical value. When no operation is performed, the data can be used as a reference.
