hi, i’m going into doing a diagnostic radiography course for 3 years. i’d like to switch onto sonography after i graduate. will i be able to do a postgraduate degree in medical imaging immediately after graduating? or will i need years of experience before i apply. i’d like to know now so in 3 years time i’m not stuck. if i do need experience, how many years? and if not, do i need a specific grade? will i have less of a chance at getting a job as a sonographer if i dont have radiography experience?
