Staging of Bronchogenic Carcinoma at Tertiary Health Care Centre with Multidetector Computed Tomography and Histopathological Correlation

Abstract

Medical College Kota (Rajasthan) will be taken. Inclusion criteria Patients with clinically or radiologically suspected bronchogenic carcinoma. Patients in whom histopathological correlation is available. Exclusion criteria Patients in whom histopathological correlation is not available. Severely debilitated patient Renal impairment Allergic to contrast media Previously diagnosed cases of bronchogenic carcinoma who were treated and now comes with recurrence. Method of collection of data Data will be collected from cases of suspected bronchogenic carcinoma referred for CT scan of thorax by purposive sampling using a proforma. All scans are done using GE bright speed 16 slice MDCT with 120 KVp and 300 mAs with 5mm section thickness, retro reconstruction of 0.625mm section thickness and reformation. Contrast study is done using 70-80 ml of 350mg/ml non-ionic iodinated contrast, injected using pressure injector at the rate of 3-4ml/s. Lung lesions are characterised based on the site, size, enhancement pattern, presence of calcification, cavitation, involvement of the hila, pleura, chest wall or mediastinum MDCT findings are correlated with histopathological examination of the specimen obtained from FNAC / biopsy of the lesion.
