Guided Interventions for Prostate Cancer Using 3D-Transurethral Ultrasound and MRI Fusion
Abstract
Gland-sparing procedures that target specific areas of the prostate have been reported, using laser and HIFU techniques. These focal therapies require real-timevisualization of the prostate during intervention, which is cumbersome to perform while the patient is in an MRI. Magnetic Resonance-Ultrasound (MR-US) fusion allows for specific targeting of the tumors in real-time during clinical interventions, outside of an MR suite. However, existing MR-US fusion exclusively utilizes TRUS. By utilizing a circumferentially wrapped catheter-based transducer, the entire prostate may be visualized at once; improving image registration and reducing motion errors. 3D TUUS imaging has been demonstrated in a phantom setting illustrating that the entire prostate gland can be visualized at once. This imaging advance may serve as a platform technology allowing the development of image guided focal prostate therapy.
