Abstract

Authors retrospectively analysed the diagnostic values of oblique tomography of hilum over simple chest PA &AP tomography in 129 cases at Seoul National University Hospital during 3yrs from may 1979 to may 1982. Theresults are as follows; 1. Among 129 cases, 42 cases were lung cancer, 24 cases were tuberculosis, 22 cases wereprominent pulmonary artery, 10 cases were metastasis, & etc. 2. In 42 cases of lung cancer. 1) Diagnostic accuracyof oblique tomography in the evaluation of hilar lymphadenopathy was 92%, that of AP tomography & simple chest PAwere 67% & 54% respectively. 2) Diagnotic accuracy of oblique tomography in the evaluation of endobronchial lesionwas 95%, that of AP tomography & simple chest PA were 24% 14% respectively. 3. It is suggested that in lung cancerif there is no evidence of hilar enlargement in simple X-ray, 55degrees oblique tomography is recommended forevaluation of hilum, or if hilar enlargement is shown in simple X-ray, then AP tomography or CT is recommended forevaluation of mediastinum.
