Abstract:
Objective To analyze HRCT and thin-slice CT scan findings in 150 patients with pulmonary diffuse mild micronodule, and to find the features with the purpose of identifying random micronodule, peri-lymphatic micronodule, and centrilobular micronodule. Methods The useful features in 150 patients with pulmonary diffuse mild micronodule were translated into scores by means of discrimination method of large log-likelihood to identify the micronodular category. Results The accuracy of diagnosis was 94.0% for random micronodule, 76.0% for peri-lymphatic micronodule, and 90.0% for centrilobular micronodule. Conclusion HRCT and thin-slice CT scans were helpful in differential diagnosis of pulmonary diffuse mild micronodule. The discrimination method of large log-likelihood was propitious to diagnosis and differential diagnosis.
