ABSTRACT
PURPOSE:
To analyze the influence of radiologic expertise in detecting lung tumors on chest radiographs. MATERIALS ANDMETHODS:
We retrieved posteroanterior chest radiographs and CT examination obtained from 283 patients with solitary primary malignant lung tumors who underwent surgical resection. There were 176 men and 107 women with a mean age of 67.0±9.1 (SD) years (range 33-88 years). Thirteen first-year post-graduate (PGY-1) trainees and nine pulmonary specialists (three radiologists, three thoracic surgeons, and three pulmonologists) interpreted the chest radiographs. Detection rates among trainees and specialists were compared using Student t test.RESULTS:
The total numbers of detected tumors ranged from 103 (36.4%) to 136 (48.1%) with a mean of 127.9±9.1 (45.2±3.2%) in the trainee group, and 137 (48.4%) to 182 (64.3%) with a mean of 161.6±13.1 (57.1±4.6%) in the specialist group; the intergroup difference was statistically significant (P<0.001). Significant intergroup detectability differences of >10% were noted for tumors in the peripheral zone with (i) ground glass opacity (GGO) ratio ≥10% and <70% and any size, or (ii) GGO ratio <10% and size ≤2cm; and for tumors hidden by the mediastinum, heart, or diaphragm with (i) GGO ratio ≥10% and <30% and size >3cm, or (ii) GGO ratio <10% and size >2cm.CONCLUSION:
Our study demonstrates significant differences in lung tumor detectability on chest radiographs between PGY-1 trainees and pulmonary specialists according to tumor size, extent of GGO, and tumor location.Palavras-chave
