THE NORMAL NASAL CYCLE

Description : The state of vasodilatation (engorgement) and vasoconstriction (of erectile tissue of the inferior turbinate and septal swell body normally alternates between the nasal cavities i.e. as one side undergoes vasodilatation, the other becomes vasoconstricted. This is called the nasal cycle. In this T2 weighted magnetic resonance scan, note the bright areas which represent vasodilatation of the right inferior turbinate and nasal septum.
