This is such a "nice" description. A more realistic desrciption is the machine is a huge monstrosity and very very noisy. Additionally, you forgot to mention a HUGE negative about these machines, once you get rolled in, the machine is literally abouit 1 inch from your entire body - on all sides. You can't move at all! If you are unconfortable in small places you will freak out! 10-15 minutes is IF it goes perfectly. Mine took about 30 minutes as she keep getting mad because I coughed or breathed or ever so slightly moved. It was by far the worst experience. Also, the machine gives off so much radiation, the tech stays outside the room. That is not comforting.

Roentgen

CT scans on average take only a couple of minutes. From your description, it sounds like you had an MRI. MRI uses radiofrequency waves with a strong magnetic field to produce images, not radiation. MRI’s also take much longer and are typically very confining compared to a CT. If you are unable to hold still, the procedure will be prolonged due to the motion distorting the images. In addition… radiology technologists are exposed to radiation every working day of their lives so you cannot blame them for leaving the room, plus the consol to control and run the machine is outside the room.
