[Use of high-resolution algorithms and thick sections in computerized tomography staging of bronchial carcinoma]

The purpose was to determine whether 8 mm slice sections with high resolution algorithms would prove superior to standard methods for the CT staging of bronchial carcinomas. The raw data from CT examinations in 50 patients using standard methods and the high resolution method was calculated, documented and compared. Within the lung parenchyma, small foci or metastases, peritumorous infiltrates, bronchial narrowing, bronchial outlines, vessels and areas of poor aeration were significantly clearer. Pleural thickening and subpleural fat stripes were also better seen. Abnormalities in the mediastinum were equally well shown. High resolution algorithms with 8 mm slice sections are recommended for routine staging of bronchial carcinomas, particularly if the calculations can be done quickly, as is possible on modern apparatus, without increasing the duration of the examination.
