While standard isoflurane anesthesia does not easily allow visualization of small vessels in mice using T2*-weighted imaging, ketamine/xylazine anesthesia enables the visualization of an impressive fraction of the vasculature, without the need of an external contrast agent. Visualization can be further modulated by modifying the breathing gas.
