positron emission tomography (PET)
A CT scan immediately after a stroke is usually looking to see if the stroke caused any bleeding. ( a hemorrhagic stroke ) If the dye were given it might hide any trace of blood. There are protocols in place as to how to treat a stroke and if bleeding is seen it changes what is done to help the patient recover from the stroke.
I am not aware of "measurements" but some test that are done are CT and MRI of the brain, a swallowing test, and bloodwork. After a time there may be some neurological tests done as well. Hope this is what you are after.
You experimentally test it
You can get a blood test done, which is more accurate than a home urine test. Also, an ultrasound test can be done to actually see the pregnancy.
A MBS is done to a patient that has had a stroke/CVA to see if there is a swallowing problem. Stroke patients often have speaking problems due to cranial nerve fallout. These cranial nerves are also responsible for the sensory and motor movements for swallowing. if these become damaged, swallowing problems may occur. A MBS looks to see if the patient si swallowing safely and on what consistencies they are not. A MBS is used to see if there are any compensation techniques that can make the swallowing safer or if therapy is indicated. This is done by a Speech Pathologist and a Radiologist

There is no test that can be done to see if you would suffer from altitude sickness or not. The only way to find out is to climb high, slowly and see how you get on.
