Neck MRI and CT scan images

Figure A below is a MRI image of a sarcoma in Carl's neck as of Jan 5, 2011 with some added 'visual' information. In photo shop I added colors and labels, and drew a rough outline to help you orient the placement of the head, which hopefully helps you better understand the MRI.

In Figure A, the vertebrae (neck bones) are in green. The vertebrae part on the left in green (front of the neck) rings the spinal column and connects to the green part on the right (in the back of the neck).

The photo below shows a neck vertebrae bone as it would look if your were looking from the top of the head. You can see how the bone has a ring. The ring circles the spine.

The next visual labels different parts of the vertebrae.

In Figure A, the spinal column (in yellow) is protected by a fluid filled sack. Perhaps you can now see the bad news of Figure A.

The nasty sarcoma tumor (shown in red on Figure A) is impinging (almost touching) the spinal column. It is squishing the fluid filled spinal sack. Unfortunately, the sarcoma tumor has also eaten away and destroyed part of the bone in the back of the C2 vertebrae, and possibly others (C3?). Destroying parts of the bone of the vertebrae - Bad. Touching the spinal column (i.e. the spine) - Well, that would be way worse.

Below are images from a CT scan of Carl's head taken from the top of the head looking down. This CT scan is from January 5, 2011. CT scans show bone details clearly. You can see the vertebrae glowing in white. Instead of being shaped like the photo above, the white bone has been replaced on the right with ominous gray tumor material.

Below are three MRI images of the same cross section, again, from Jan 05, 2011. Above, CT scans, below MRI scans.

The three MRI images show different ways the MRI contrast can be adjusted to better see various types of tissues.

The final two images below are from a CT scan adjusted to show different structures. The views are a cross sections of Carl's neck from the back (image on the left), and a side view of the neck (on the right).

CT scan of head and neck arteries and veins

These images document why the sarcoma tumor in the neck had to be surgically removed. Carl had surgery to remove the tumor on January 24, 2011.
