[Abstract] Objective: To retrospectively evaluate dynamic contrast-enhanced MRI (DCE-MRI) features of hysteromyoma after high-intensity focused ultrasound (HIFU) ablation.Materials and Methods: Thirty-there patients with hysteromyoma underwent HIFU ablation. In all patients, DCE-MRI was performed prior to and 1st weeks after HIFU. Then the patterns of the peripheral enhancement of hysteromyoma were evaluated, judged it was complete ablation or not.Results: In twenty-five of thirty-there patients, thin rim enhancement around the ablation zone was seen on the DCE-MRI after first ablation, which showed no relapse lesion after 6 months, that complete ablation could be confirmed. In the remaining eight patients, nodular or irregular thick enhancement was shown on the DCE-MRI, viable tumour was confirmed by biopsy in five patients, the volume of the remains increased 6 months after HIFU ablation.Conclusions: The DCE-MRI characteristics of successfully ablated hysteromyomas included central dark signal intensities with thin rim enhancement, nodular or irregular thick enhancements should raise concern of partial ablation.
