Detailed Description
Sonazoid is a second generation ultrasound contrast agent, which is composed of microbubbles containing chemically stable and insoluble Perfluorobutane (PFB) gas and a hard shell of phosphatidylserine sodium (2-3 μ m in diameter) wrapped in the outer layer. These microbubbles can generate stable nonlinear oscillations in a low-power acoustic field and generate echoes at the second harmonic frequency of the transmitted pulse for enhanced contrast harmonic imaging.
Because Sonazoid has the advantages of ultra long time development and good stability, Sonazoid has significant clinical advantages in the diagnosis of not focal liver lesions(FLLs) but breast tumor and other organ. However, there is no study based on contrast enhanced ultrasound(CEUS) using Sonazoid in early detection of Endometrial carcinoma. Therefore, based on the advantages of the new ultrasound contrast agent, using qualitative analysis and quantitative analysis method to collect large samples, compared with diagnosis results of standard reference, which has important clinical significance for early diagnosis, early detection and improving the accuracy of diagnosis of Endometrial carcinoma.
