Preliminary clinical study on contrast-enhanced ultrasound for the peripheral pulmonary tumors / 中华超声影像学杂志

ABSTRACT

Objective To study the feasibility and characteristic findings of contrast-enhancedultrasound(CEUS)on peripheral pulmonary tumors.Methods Twenty patients with peripheral pulmonarytumors proven by pathology were studied.They were divided into two groups:primary pulmonary tumors (n=15),and metastatic pulmonary tumors(n=5). The dynamic enhancement images were stored and Strip enhancement was dominant in the primary pulmonary tumors,while dot enhancement was dominant in ascended quickly and descended slowly,while ascended slowly and descended slowly in majority of metastaticThe modes of enhancement and time-intensity curves were all different in primary and metastatic pulmonary tumors.Contrast-enhanced uhrasound is promising in the diagnosis of peripheral pulmonary tumors.
