The diagnosis of the condition can be confirmed only when other neurological abnormalities are excluded including trigeminal neuralgia which develops as a result of some structural lesions of the nerve. He is famous in the field of NMR for the so-called larmor equation, which states that the frequency of precession of the nuclear magnetic moment () is directly proportional to the product of the magnetic field strength (B0) and the gyromagnetic ratio ( ): = B0. MRI can show tortuous vessels and the trigeminal nerve together on one single image by means of a 3D gradient-echo FLASH sequence with an effective slice thickness of approximately 1 mm and secondary reconstructions in every desired plane.
