Infusion of contrast microbubbles into the brain microvasculature of a mouse.

Vasculature in the mouse brain, visualized with color Doppler during transient carotid artery occlusion.

Microvasculature in the mouse brain visualized in 4D after contrast microbubble injection.

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.

3D rendered surface view of the mouse brain segmented by anatomical region based on ex vivo high frequency ultrasound images.

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. The red, white and blue color represents a parametric map of oxygen saturation.  The right hemisphere does not fully recover sO₂ levels post-reperfusion/normoxia that are shown in the left hemisphere, indicating a cerebral infarct, especially in cortical and subcortical areas.

3D rendered color Doppler (red and blue) and ultrasound (greyscale) coronal image showing direction and velocity of blood flow in the neonatal rat brain.

3D rendered coronal ultrasound (greyscale) and photoacoustic (red) images of a mouse brain during ligation of the right common carotid artery. The red color represents higher oxygen saturation clearly showing lower sO₂ in the right hemisphere.

3D rendered color Doppler (red and blue) C-scan image showing direction and velocity of blood flow in the mouse brain and surrounding structures.

3D rendered co-registered ultrasound (greyscale) and photoacoustic (red and white) image showing a parametric map of oxygen saturation with red signals indicating higher sO₂ values.

Co-registered 3D rendered ultrasound (greyscale) and color Doppler (red and blue) coronal image of a mouse brain during ligation of the right common carotid artery.  The red and blue color represent blood flow velocity and direction clearly showing impaired blood flow in the right hemisphere.

3D rendered photoacoustic image showing cerebral blood signal in the mouse brain.

Ultrasound (top) and photoacoustic (bottom) coronal images of a mouse brain during ligation of the right common carotid artery. The red, white and blue color represents a parametric map of oxygen saturation clearly showing lower sO₂ in the right hemisphere.
