there are several possibilities why your ct scan may have been cancelled. your doctor who ordered the ct scan should be able to tell you the reason. often there is concern if a person's blood work shows an abnormal creatinine test prior to getting a ct with contrast dye. the creatinine test indicates how well your kidneys are functioning. the use of contrast dye with a ct scan can sometimes cause kidney problems especially in people who already have impaired kidney function.
what are some reasons an already scheduled ct scan would be cancelled following lab work? . i have what initially felt like (and what my doctor thought was) an intestinal infection. she scheduled me for a ct scan and sent me over for urinalysis and bloodwork. the radiology department left me a message today stating that my appointment had been cancelled due to lab results. aside from pregnancy are there are any conditions that would show up on ua/bloodwork labs that would keep me from getting a ct scan?
