TI  - A role for subtraction scintigraphy in the evaluation of lower gastrointestinal 
      bleeding in the athlete.
PG  - 923-8
AB  - While lower gastrointestinal haemorrhage (LGIH) in the athlete tends to be 
      self-limiting in the majority of athletes, recurrent symptoms occur in some 
      athletes. It is important to identify the smaller percentage of athletes in whom 
      risks and recurrence are greater because both their general health and athletic 
      performance might benefit from more rigorous clinical evaluation. Technetium-99m 
      red blood cell ((99m)Tc RBC) scintigraphy is a technique for detection and 
      localisation of LGIH and offers a number of significant advantages over other 
      imaging modalities in the evaluation of LGIH. Nonetheless, there are a number of 
      limitations recognised in (99m)Tc RBC scintigraphic evaluation of LGIH. 
      Subtraction scintigraphy in (99m)Tc RBC evaluation of gastrointestinal 
      haemorrhage may offer a tool to overcome limitations of conventional 
      scintigraphy. In essence, subtracting a nominal 'mask' or reference image from 
      all subsequent images provides a mechanism to view only the information 
      contributed by accumulated bleeding, removing potential sources of both 
      false-positive and false-negative findings. While the limitations of procedures 
      available for the evaluation of LGIH are generally prohibitive of effective 
      application in the obscure bleeding associated with athletic performance, 
      adopting subtraction methods in conjunction with conventional (99m)Tc RBC 
      scintigraphy may offer a valuable tool in identification and localisation of 
      bleeding sites. The general health and athletic performance may be enhanced in 
      some athletes when the underlying cause of bleeding can be more appropriately 
      managed.
