The clinical symptom was cough, hemoptysis for two months. 2002-2003 Final Examination of Foreign Students (Answers) I. 1 trachea 2 right main bronchus 3 left main

8、 bronchus 4 scapula 5 clavicle 6 sternum 7 azygos vein 8 aortic arch 9 left pulmonary artery 10 upper left cardiac border 11 lower left cardiac border 12 right atrium 13 lower lobe arteries 14 lateral costophrenic angle 15 breast II. 1. Fogging effect: During 23 weeks after cerebral infarction, the

9、density of the infarcted lesion increased and became isodense. This is due to reduction in edema ,leakage of proteins from cell lysis and invasion of macrophage. 2. Chemoembolization: A technique that combines transcatheter arterial infusion of chemotherapy drugs and embolization. III. 1. epidural h
