64排螺旋CT及MPR技术对肺尘埃沉着病合并肺结核的诊断

目的探讨64排螺旋CT及其MPR技术对肺尘埃沉着病合并肺结核的诊断价值。方法对50例肺尘埃沉着病患者进行胸部64排螺旋CT检查,得到胸部轴位(层厚1 mm)及MPR图像,分析肺尘埃沉着病合并肺结核CT表现,对早期发现肺尘埃沉着病合并结核有重要价值。结果肺尘埃沉着病合并血行播散型肺结核1例,继发性肺结核48例,其中渗出浸润为主32例,占66%;干酪为主型6例,占12.5%;空洞为主型10例,占20.8%;肺尘埃沉着病合并结核性胸膜炎1例,占0.2%。结论 64排螺旋CT及MPR技术对肺尘埃沉着病合并结核的诊断优势明显。MPR技术对胸部整体情况能多方位,直观,清晰和形象地显示,特别是晚期肺尘埃沉着病合并结核早期诊断提供较为可靠依据。

Diagnosis of 64 Slice Spiral CT and MPR Techniques in Silico Tuberculosis

Objective To explore the diagnostic value of 64 slice spiral CT and MPR technology combined with pulmonary tuberculosis of silicosis. Methods Chest 64 slice spiral CT examination of 50 cases of patients with silicosis, get the chest axis （thickness 1） and MPR image, analysis of silicosis complicated with tuberculosis CT manifestations of silicosis complicated with tuberculosis, early detection is of important value. Results 1 cases of silicosis complicated with hematogenous disseminated pulmonary tuberculosis,48 patients with secondary pulmonary tuberculosis, which exude infiltration in 32 cases, accounting for 66%; cheese based type in 6 cases, accounting for 12.5%; the main cavity type in 10 cases, accounting for 20.8%; 1 cases of silicosis complicated with tuberculosis pleurisy, accounted for 0.2%. Conclusion Diagnostic advantage of conclusion 64 slice spiral CT and MPR technology on silicosis patients complicated with tuberculosis. MPR technology on the chest overall situation can be multi-dimensional, intuitive, clear and vivid display, especially to provide reliable evidences for early diagnosis of advanced silicosis patients complicated with tuberculosis.
