CT evaluation of bronchogenic carcinoma

Abstract

HRCT delineation of lung parenchyma down to the level of the secondary pulmonary lobule is possible. Spiral CT introduced in the early 1990's lead to an increase in utilization CT, a revolution that continued with advent of multi detector row CT (MDTC) scanners more recently. Helical technology permits multiple phases of scanning to be obtained often one contrast injection. In this study CT evaluation of 50 patients with either proven or strongly suspected bronchogenic carcicnoma based on chest radiographs, bronchoscopy, cytology of bronchial washings or pleural fluid, FNAC or clinical examination was done.Before commencing CT examination, all the preceding historical, clinical & laboratory data are recorded. Most of the bronchogenic carcinoma are heterogeneously enhancing (54.3%),with ill defined/ speculated margins (73.9%) and associated with necrosis in 43.47%of cases .calcification rarely found (13%).
