ABSTRACT
Objective To explore the features of coronary artery morphological changes and left ventricular function indicators of resident population in plateau .Methods 50 plateau healthy adults and 50 plain‐and Dalian‐healthy volunteers completed coronary CTA examination .We measured the pipe diameter of left main coronary atery and right coronary artery and their branches ,respec‐tively .Furthermore ,SV and EF value of left ventricular cardiac function indexes and the wall thickening of free ventricular wall at left ventricular end systolic were measured .Results The average diameter of proximal right coronary of plain‐and Dalian‐healthy volun‐teers thicker than plateau group ,with statistical difference ;Other coronary artery branch did not exhibit any significant between‐group differences ;The two groups did not show significant between‐group differences with heart function indexes .Conclusion The body circulation system have adaptability and compensatory changes of resident population in plateau ,and their coronary artery mor‐phology and left ventricular function are as similar as plain people .
ABSTRACT
Objective To investigate imaging findings of primary laryngeal amyloidosis in order to improve the diagnosis of this disease.Methods Findings of plain CT and contrast enhanced CT scanning of three cases of laryngeal amyloidosis confirmed by biop-sy were investigated.Results Of the three cases,one case was located,two cases was diffused.The pharyngeal stenosis,bronchus in-vasion and calcification were showed in one case respectively.All the three cases showed mild homogenous enhancement similaryly. Of the three patients,one case was hospitalized by hoarseness and a serious sense of obstruction,and two cases by feeling pharyngeal pain.Conclusion This disease is rare ,and difficult differentiated from laryngeal carcinoma,but a correct diagnosis can be obtained by combining the CT findings with clinical manifestation.
