Someone posted here that MRI is prefferable to CT for diagnosising sinus
disease.
We never order an MRI for Sinus Diagnosis because
a. It is too sensitive . Shows a spot of mucus as terrible disease
b. doesn't tell us the condition of the bonsy septa
c. useless for any type of surgery
d. simply of no value.

Afer the CT, if we need furtner information re a fungal infection, then the MRI
of the Sinus might be done as this is of diagnostic help.

With the high cost of medicine already, it is pointless to do a test - MRI of
the sinuses if it is not going to give you useful information.

Re headaches: There are certain defintitions of headaches that needs to be
elaborated. If you define  a Migraine as a vascular spasm (usually the aura)
followed by a significant vascular dilatation, then you realize there are many
other kinds of headache - cervical, muscular, sinus pressure, pre-menstrual,
menstrual, etc.
It is important to realize that there are mnay triggers for migraine including
smelliy cheeses and red wine.
Many Migraine patients are benefttted by shower excercise - hard shower to back
of neck, gently rotate head side to side daily. They may train the blood
vessles not to be so spastic.

You can also make a mighraine headach: apply cold to the back of the neck. when
it is really cold , suddenly apply heat to that area. You will get a migraine.
Common to scuba divers - come up from the cold, sit with hot sun on their neck
- get a migraine type headache.
