Neuroimaging Techniques for Seeing the Mouse Brain in vivo and in Real-time
Visualize functional processes for your small animal neuroscience research including stroke, cancer and in vivo delivery of drugs, stem cells, or other agents.
Compared to other preclinical neuroimaging techniques, Vevo imaging systems are non-invasive, non-ionizing, and offer a more cost effective solution.
Ultra-high frequency ultrasound and photoacoustic imaging is capable of assessing many neurologically relevant parameters in 2D and 3D such as:
- Blood flow
- Perfusion
- Oxygen saturation
- Total Hemoglobin
- Contrast agents (ultrasound microbubbles, NIR dyes, nanoparticles)
In addition, the Vevo BRAIN stereotactic frame and neuroanatomical atlas facilitates mouse brain imaging for increased ease-of-use and reproducibility.

Lesion in Embryo Spine - Spina Bifida Rat Model
Spina bifida is a neural tube defect that results in incomplete closing of the spinal cord. Spina bifida is associated with abnormalities in the cerebellum and cisterna magna during fetal development. This image acquired using the Vevo 3100.
Embryo Cerebellum - Spina Bifida Rat Model
Spina bifida is a neural tube defect that results in incomplete closing of the spinal cord. Spina bifida is associated with abnormalities in the cerebellum and cisterna magna during fetal development. This image acquired using the Vevo 3100.

Ischemia/hypoxia stroke model
Plot of oxygen saturation (sO2) over time in the left (pink) and right (orange) cortical and subcortical hemisphere ROIs while restoring breathed oxygen to 100% from 7.5% post ischemia/hypoxia for stroke induction. Ultrasound (top) and photoacoustic (bottom) coronal images in the right panel show a frame of mouse brain post ischemia/hypoxia.
