A stool marker formulation for oral administration and suitable for use in CT Colography including a material adapted to provide marked stool which has a modified response to radiation relative to unmarked stool. Radiologically scanning the colon of a patient treated to produce marked stool produces data which can be manipulated to provide a representation of the colon including where present, a polyp. The active ingredient is preferably barium sulfate which has been destabilised to reduce its resistance to flocculation.
