Low-flow vascular malformations (venous and lymphatic)
are traditionally treated using ultrasound and
fluoroscopy guided percutaneous sclerotherapy. However,
certain lesions are particularly difficult to visualize
and/or treat using these modalities. Real-time MR-guided
intervention may serve as a safer alternative with
better visualization of surrounding critical soft tissue
structures and with less or no exposure to ionizing
radiation. We present here our experiences with
targeting and treating low-flow vascular malformations
using real-time MR imaging.
