First of all try to see Neurologist first then follow his advise.

For additional info.;MR imaging of the body is performed to evaluate:
Organs of the chest, abdomen and pelvis—including the heart, liver, biliary tract, kidney, spleen, and pancreas and adrenal glands.
pelvic organs including the reproductive organs in the male (prostate and testicles) and the female (uterus, cervix and ovaries).

And for the Head, I think CT-Scan will be the best.
