One thing I will say is because of computer processing advances, you get your results for CT, X-Ray & PET scan pretty fast.
When I got my 1st PET scan back in 2000, I had to lay in the machine, as still as possible, for 1 hour & 45 mins. Tech told me it would be about 4 - 5 hours until the image was ready for viewing. Nowadays it's about 40 mins for a full neck to abdomen scan.
CT scans of that area used to take about 25 mins & you had to wait close to 2 hours to get the results. That time being because the machine had to assemble all the images into a readable file. Then you had to have someone review the file. Last time I got my CT, I had the results in 1/2 an hour, with most of the delay being for the tech to read & compare the file. The techs tell me that the CT scan image was assembled on the fly & is ready about 3 minutes after the scan finishes.
