Composite of imaging machines and radiological images

An MR image of the cranial arteries. Colors change at bifurcations.

MR image of the heart (single slice) color coded for the concentration of contrast agent (an indicator of blood perfusion)

Diffusion Tensor MR images of the brain color coded for the orientation of neurons

An FDG-FLT PET image of a brain tumor overlayed on an MR image of the brain to show the tumor in situ

Functional MR images of the brain

A MR thermometry map (blue: cold, red: hot) of a cross-section of a tissue-mimicking phantom which was heated with a High-Intensity Focused Ultrasound (HIFU) beam from the left. The map demonstrates that HIFU can heat tissue at depth without heating the intervening tissue and thus may be used to ablate tumors.
