What is the difference between CT and spiral CT?

You said the ordinary CT should be the old CT, spiral CT inspection time to be faster, the effect is also better, the specific is too professional, now generally do not consider doing the old CT inspection, because the inspection effect is not good (or even can not be seen), the name is to save money, in fact, there is a possibility that the money is spent in vain, the head + neck inspection, different levels of hospital charges are not the same, the three hospitals than the second price is a little higher. The price of the second A to be higher, in addition, the concept of the neck is too big, just the head, about 300 or so, cervical discs are more expensive than the head, if the cervical vertebrae, it will be about 700, if the other organs of the neck is another calculation.
