What does coronal scan mean?
Coronal view: A coronal view will give images of the sinuses from front to the back.
Does sagittal CT go left to right?

What is coronal and sagittal?

What is a coronal image?
A coronal plane (also known as the frontal plane) is any vertical plane that divides the body into ventral and dorsal (belly and back) sections. It is one of the three main planes of the body used to describe the location of body parts in relation to each other axis.
Does a CT scan show tumors?
CT scans can show a tumor’s shape, size, and location. They can even show the blood vessels that feed the tumor – all without having to cut into the patient. Doctors often use CT scans to help them guide a needle to remove a small piece of tissue. This is called a CT-guided biopsy.
