Poorer quality images initially, equipment are less costly: Images less sharp smaller and. It is easy to hold meaning you will get more use out of the phone however the camera can be shaky causing the photo to be unfocused and unprofessional. Nuclear medicine scanning involves the use of radioisotopes and so has the usual risks associated with ionising radiation.
