In the last six years, 544 consecutive patients with nonsmall-cell bronchogenic carcinoma were studied with MRI. MR results were compared with surgical specimens and pathologic findings. Both TNM classification and ATS nodal mapping were considered. Local tumor extent (T parameter) was correctly identified in 67.2% of cases, understaged in 19.4% and overstaged in 13.4%. Lymph node metastases (N parameter) were adequately assessed in 55.5% of cases, understaged in 20.3% and overstaged in 24.2%. Considering two groups of patients, the first one with early stage disease (T1-T2, N0-N1) and the second one with advanced stages (T3-T4, N2-N3), MRI exhibited 84.6% overall accuracy, 57.3% sensitivity and 93.7% specificity for the T parameter and 72.3% accuracy, 65.2% sensitivity and 75.1% specificity for the N parameter. In conclusion, MRI did not provide the expected results in the staging of nonsmall-cell bronchogenic carcinoma, but improvement will probably be achieved with technological evolution.
