Characteristic analysis of dynamic enhanced 64 row-spiral CT for solitary lung cancer nodules with different pathological patterns
摘要
Abstract
Objective To analyze the characteristics of dynamic enhanced 64 row-spiral computerized tomography ( CT) for solitary lung cancer nodules with different pathological patterns .Methods Seventy-nine patients with histologi-cally confirmed solitary lung cancer nodules were enrolled .According to the pathological type classification , there were 17 cases of patients with squamous-cell carcinoma , 6 cases of patients with small cell lung cancer and 56 cases of patients with adenocarcinoma .All patients received plain scan and dynamic-enhanced scan by using 64 row-spiral CT.We recorded the numerical changes, tmax, intensive way, intensive net added value, reinforcement ratio and expurgation rate in delayed scanning of 180 seconds , 300 seconds and 600 seconds after dynamic-enhanced peak value .Results The CT values of all kinds of solitary lung cancer nodules first increased and then decreased with the prolonged time , and the peak appeared in 60-180s.The time to peak of the small cell lung cancer nodules appeared earlier than the other two types .About 75%ade-nocarcinoma nodules were evenly reinforced , about 64.7% squamous-cell carcinomas nodules were unevenly reinforced , the small cell lung cancer nodules had no obvious way of strengthening .Significant difference was found in the constituent ratio of schedule of reinforcement between adenocarcinoma and squamous cell carcinoma ( P<0.05).The reinforced net added value of adenocarcinoma and squamous-cell carcinoma was higher than that of the small cell lung cancer nodules ( P<0.05).The reinforced net added value of nodules in the adenocarcinoma and squamous cell carcinoma had no statistical -ly significant difference (P>0.05).The nodule reinforcement rate of all type had no statistically significant difference in delayed scanning of 300 seconds (P>0.05).The relatively clear value and expurgation rate in delayed scanning of 180 seconds of the small cell lung cancer was higher than the other two types , and the relatively clear value and expurgation rate in delayed scanning of 600 seconds of the adenocarcinoma was lower than the other two types (all P<0.05).Conclusions The small cell lung cancer has a low tmax , low intensified net added value , and the relatively clear value and expurgation rate after 180 s is higher .The reinforcement of adenocarcinoma is uniform and it has a low relatively clear value and expur -gation rate after 600 s.The reinforcement of squamous-cell carcinoma is non-uniform.关键词
