Abstract:
Objective To investigate the value of parametric imaging of CEUS in uterine fibroids with different signal intensity on T2WI by high intensity focused ultrasound (HIFU),and dynamic vascular pattern (DVP).Methods Totally 16 patients with single uterine fibroids were divided into high intensity group (n=6),isointensity group (n=4) and low intensity group (n=6) according the signal intensity on T2WI before HIFU treatment.CEUS were performed on each patient.SonoLive CAP software was used to analyze the CEUS images and DVP parametric images were reconstructed.Results The maximum intensity,rising time,time to peak and mean transit time were (235.40± 35.46)％,(22.80± 3.16)s,(25.09±2.44)s,(125.78 ± 27.63)s in high intensity group,(71.97± 2.43) ％,(24.85±3.22)s,(32.81±3.92)s,(66.52±3.48)s in isointensity group and (16.17±2.83) ％,(25.42±2.66)s,(32.82±3.76)s,(64.27±3.33)s in low intensity group.There were statistically significant differences among three groups (all P＜0.05).DVP curve was divided into two types:non-washout in high intensity group and cystic type in low intensity group.Conclusion CEUS and DVP imaging can directly quantitively display the difference of blood perfusion among the uterine fibroids with different signal intensity on T2WI which can provide important information for HIFU treatment in uterine fibroids.
