title: MRI Scanners Guide Therapy to Tumors.
abstract: A new study shows that MRI scanners can direct magnetically labeled macrophages bearing an oncolytic virus toward primary and metastatic tumors in mice. Researchers hope this approach, called magnetic resonance targeting, can be scaled for use in humans, to improve the delivery of cell-based cancer therapy.
