Application of Contrast-enhanced Ultrasound in the Diagnosis of Ovarian Masses / 医学研究杂志

ABSTRACT

Objective To investigate the application value of contrast-enhanced ultrasound in the diagnosis of ovarian masses.Methods Ninety-four patients with ovarian masses were observed and undetermined by conventional ultrasound examinations who were underwent contrast-enhanced ultrasound examinations and were made the time-intensity curve.By analyzing the perfusion characteristics and the quantitative parameters of time-intensity curve,we compared the difference of different masses.Results The perfusion characteristics and the quantitative parameters of the time-intensity curve were different.The arrival time and the time to peak intensity of benign masses were later than those of malignant tumors.The peak iniensity of benign masses was lower than that of malignant tumors.There was a significant difference between the two groups.The arrival time and the time to peak intensity of benign tumors were later than those of malignant tumors.The peak intensity of benign tumors was lower than that of malignant tumors.There was a significant difference between the two groups.The time to peak intensity of non-tumorous lesions was later than that of malignant tumors.The peak intensity of non-tumorous lesions was lower than that of malignant tumors.There was a significant difference between the two groups.The arrival time of non-tumorous lesions was earlier than that of benign tumors.There was a significant difference between the two groups.Conclusion The perfusion characteristics and the quantitative parameters that draw from the time-intensity curve of different masses are different.Contrast-enhanced ultrasound is contributive to the diagnosis and the differential diagnosis of different masses.Contrast-enhanced ultrasound also has great clinical values to those ovarian masses whose ultrasonic appearance is complex and difficult to diagnose qualitatively.
