@BlacknBlueSaint You did a great job getting the scans uploaded!
If you want to take a look at these scans in 3D the best program is Slicer. Take the series with the most slices, in your case Series 4, and follow the directions in this post to reconstruct them into a 3D model for viewing manipulation. Making Your Own 3D Images from CT Scan- 3D Slicer Tutorial
You can then make similar 3D models like the radiologist did. The reason the 3D models the radiologist made don’t work in DicomLibrary is because they are just 2D pictures taken from a 3D reconstruction. You may have multiples images that allow you to simulate spinning around the model, but your really just flipping between 2D images. All the images below were made in Slicer with your Series 4 dicom stack.
Is my stylohyoid ligament calcified? There is some minor calcification. The worst side of the calcification is on the right and it does have some compression of the dominant right jugular vein. I circled in red the compression from the right styloid and right C1 transverse process.
Is my hyoid bone elongated at the tips, or are there any other problems with it? The hyoid bone on the right is somehow stuck between the carotid artery where it splits. Pretty sure this is not normal. I don’t know how this affects you, as you turn your head, eat or talk. The connected ligaments/muscles must somehow overlap the external caritod artery at the very least. It does look like the ECA has adapted over the years to account for this.
Do you see any stenosis or hypoplasia of my major arteries and veins, either in my neck or head that might make me feel strangled when lying down? (I already know about the right vertebral hypoplasia and the narrowing of the left transverse sinus.) Given that the left transverse sinus is narrowed significantly, the right transverse sinus I would expect it to be much larger given it’s doing most of the work.
Also there is a calcification where the right jugular vein meets the subclavian vein. I have this calcification on my right side too, but yours is larger and on your dominant jugular vein. This is something new that I have come across and have no idea if it is significant or not. This is obviously a question for a neurosurgeon or similar specialist.
