Method
Manual. Each caudate nucleus should be contoured separately. Co- registration with T1-weighted MRI is required for delineation. The caudate nucleus is a curved, tadpole-shaped, structure composed of three parts: a large anterior head, a tapering body, and a thin tail, which wraps around the thalamus, following the curva- ture of the lateral ventricle. It is isointense to cortex on T1-imaging.
Structure Boundaries
Cranial Boundary
The head of the caudate nucleus forms the lateral wall of the anterior horn of the lateral ventricle and meets the putamen antero- laterally, and the nucleus accumbens inferiorly.
Lateral Boundary
The body of the caudate nucleus lies lateral to the lateral ventricle, and medial to the internal capsule. The tail curves back anteriorly along the roof of the temporal horn of the lateral ventricle, and ends in the amygdala.
