Anesthesia is an essential and yet often overlooked component of preclinical DCE-MRI study. The goal of this study is to investigate whether anesthesia method has any effect on the tumor vascular permeability measurements by DCE-MRI with a macromolecular contrast agent, albumin-(DTPA-Gd) in human breast cancer MCF-7 mouse xenografts. Preliminary results from mice anesthetized by isoflurane alone, and a combination of ketamine/acepromazine induction and isoflurane maintenance are reported here.
