Description
Summary:To study the correlation between CT/MRI features and surgical and pathological findings of cancerous invasion of the main pulmonary artery (CIMPA) in lung cancer and to evaluate the role of CT and MRI in making surgical plan. CT findings in 15 cases and MRI findings in 13 cases were observed and blindly compared with surgical and pathological findings in this prospective study of 23 cases of central type lung cancer. The CT and MRI features showed as follows: the wall thickening sign in 73.7% of CT and 84.6% of MRI; lumen narrowing sign in 55.3% of CT and 69.2% of MRI; peri-vascular fat sign in 100.0% of both CT and MRI. Two types of CIMPA were visualized: contacted type (10 cases in CT and 7 cases in MRI) and encased type (5 cases in CT and 6 cases in MRI). Surgically, contacted type was found in 10 cases who all underwent lobectomy with sleeve-angioplasty. Encased type was found in 13 cases, among whom unresectable in 2, pneumonectomy in 7, and lobectomy with angioplasty in 4. Of the 21 resected specimen, t
