I am frustrated UPDATE

Little story,had my colon surgery 2006, stage 3a everything have been fine since,I did chemo, pet scans, cat scans, lab work. This year my insurannce didn't approved a pet scan,because they said that with my history the guideline were not for a pet but a ct scan,so that is what was done last Sep. 2th,but in a different facility than the one that I have been going since the beginning, I didn't like that either again because of the insurance,O.K to make s long story short,they called me from my Dr. office 5 days later, and left a message saying that my scan was fine,but anyway I needed to keep my appoitment 1 week later,that appoitment was yesterday and now he tells me that he wanted to order a copy of my last ct scan so that the radiologist can compare apples to apples, because the radiologist compare it to my last pet/ct,now I have to wait til next Tuesday because he will no be at his office tomorrow or Monday, he repeated "don't worry everything is fine",I am very frustrated because when he saw the transcript of the results if he wanted to compare apples to apples, he had plenty of time to have it done and ready for my yesterday appoitment, now I am all worry for another 6 days,yesterday I almost did not sleep. My question " do you think is that necessary to compare same kind of scans?"
Thanks for any comments that you have.

UPDATE:
First of all thanks to the 3 persons than answered my post, I never get too many answers to my posts, I have good news!! Dr. finally compared ct acan to ct scan, or how he said apples to apples and both scans were identical, year colonoscopy clear as well, so I am oficially celebrating my 4 years and 2 months NED!!! I will continue praying for all of you day by day, God bless you all.
