In a 27-year-old cyclist a full-body CT scan is performed after an accident. In which three planes is the body usually depicted radiologically?

In radiology, the body is usually depicted in three planes:

1. Axial (or Transverse) Plane: This plane divides the body into superior (upper) and inferior (lower) parts. It is perpendicular to the body's long axis. In CT scans, this is the most common plane used.

2. Sagittal Plane: This plane divides the body into left and right parts. It runs parallel to the body's long axis. It's particularly useful for viewing structures like the spine and brain.

3. Coronal Plane: This plane divides the body into anterior (front) and posterior (back) parts. It is perpendicular to the ground and is useful for viewing structures like the lungs and abdomen.

These three planes are used in combination to provide a comprehensive view of the body's internal structures.
