I had an abdominal and pelvic CT scan yesterday. I was the only one out of the other 5 patients who didn't need the contrast dye. I was told they would do a scan without and then see if I needed one with. I only had a scan without and was sent on my way and told to go to my GP for results. 

My kidney function was fine from the blood test I had and I've no history of allergies. 

I'm now worried that they found something straight away and didn't need the dye. I can't stop worrying that I'm going to die. 

Is this normal or has anyone experienced this?

Thanks
