Methods of imaging the respiratory tree, associated structures and regional anatomy include: plain PA chest radiogram and lateral radiogram chest radiography with fluoroscopic screening tomographic radiography computerised axial tomography (CAT) scanning magnetic resonance imaging (NMR) scanning pulmonary angiography or ventilation / perfusion scanning bronchography mediastinoscopy thoracoscopy A chest radiograph should be examined in a systematic way: check the name on the film make an estimate of age and sex of patient if this information is not provided check the projection which should be posterior-anterior - PA the whole of the chest should be visible on the film, check for rotation and that there has been satsifactory penetration check chest expansion and the diaphragm - the right hemidiaphragm is 2 cm higher than the left check for normal lung markings - the horizontal fissure is visible in 60% of normal chest X-rays; it runs from the centre of the right hilum,...
