Abstract:
Objective To understand further the CT signs of small peripheral lung cancer and to improve its diagnostic rate by CT.Methods 63 patients with small peripheral lung cancer(diameter was approximately 3 cm)were examined with spiral CT scanning before operation.All cases were confirmed by surgery and pathology.And additional high resolution spiral CT scanning was done in 28,and enhanced CT scanning was done in 41 of them.The size,edge signs,internal texture and enhanced degree were analyzed.Results Of 63 cases,CT findings included the lobular sign in shape in 57,burr sign in 56; sign of hollowed pleura in 48; sign of blood vessel bundle in 36; sign of small bubbles in 15; sign of air bronchus in 6.Of 41 cases with additional enhanced CT scanning, the increasing range in CT value of 34 cases was over 30 HU.Conclusion Peripheral pulmonary nodules which are of more than 3 edge signs on CT are highly suspected to be peripheral pulmonary carcinoma.Enhanced CT scanning is very helpful in distinguishing benign and malignant pulmonary nodules.
