INCREMENTAL DYNAMIC COMPUTER TOMOGRAPHY IN SURGICAL TREATMENT OF PATIENTS WITH SOLITARY PULMONARY NODULES

Objective The purpose of this study is to appraise the value of incremental dynamic enhanced computed tomography in surgical treatment of patients with solitary pulmonary nodules(SPNs).Methods The data of 42 cases with solitary pulmonary nodules who underwent surgical treatment from May 2002 to June 2003 in our hospital were collected to find the relationship between preoperative dynamic enhanced CT image and postoperative pathology.Result All bronchogenic carcinoma showed significant enhancement after intravenous 100 mL iodinated contrast material.The average degree of enhancement of bronchogenic carcinoma was significantly different from that of tuberculoma and other benign lesions.Conclusion Dynamic enhanced computed tomography is very valuable in distinguishing between malignant nodules and benign ones.Emphasis should be paid to lymph nodes in the dynamic enhanced computed tomography,which is useful both to the diagnosis of SPN and for surgical treatment.
