Abstract

Purpose: A new nonrigid registration method, designed to reduce the effectof movement artifact in subtraction images from breast MR, is compared with existing rigid and affine registration methods. Method: Nonrigid registration was compared with rigid and affine registration methods and unregistered images using 54 gadolinium-enhanced 3D breast MR data sets. Twenty-seven data sets had been previously reported normal, and 27 contained a histologically proven carcinoma. The comparison was basedon visual assessment and ranking by two radiologists. Results: When analyzed by two radiologists independently, all three registration methods gave better-quality subtraction images than unregistered images (p < 0.01), but nonrigid registration gave significantly better resultsthan the rigid and affine registration methods (p < 0.01). There was no significant difference between rigid and affine registration methods. Conclusion: Nonrigid registration significantly reduces the effects of movement artifact in subtracted contrast-enhanced breast MRI. This may enable better visualization of small tumors and those. within a glandular breast.
