This study conducted a preliminary phantom study of MRI-guided vascular intervention, and evaluated the image quality of MR real-time sequences for MR compatible guidewire and balloon imaging with a 3D printed aorta phantom in a 3T MRI scanner. The results showed that the two real-time imaging sequences have sufficient guiding ability to guide the guidewire and balloon to the expected position. After comprehensive evaluation, it was concluded that the FLASH sequence was better than the True FISP sequence.
