This week we review a recent work from the team at Children's National in DC and the NIH on the use of 3D fusion of MRI images with fluoroscopy to help inform interventional procedures. Does this form of "XFM" fusion improve outcomes and reduce radiation or contrast usage? Are there procedures in which this form of imaging might be best applied? We review these and other questions with the first author of this work, Dr. Elena Amin of UCSF. doi: 10.1002/ccd.28324
