One chest CT is around 10 millisieverts of radiation. A traditional chest X-ray is only 0.02 millisieverts. Therefore a CT scan has 5,000 times the radiation dose of a chest x-ray.
A typical patient who visits the emergency room receives a cumulative radiation dose of 40 millisieverts over a five-year period. Ten percent of patients end up with 100 or more millisieverts. Both levels are well above the safety threshold for lifetime radiation exposure. Exposures above the threshold leave patients vulnerable to increased long-term risk of cancer.
Some reports suggest about one third of all CT scans may be unnecessary. Overuse of these tests may be a significant factor in raising the total public risk of cancer. Some researchers note that while the risks of cancer from CT scans remain low, the increased incidence of cancer may be considerable. To balance image quality with these safety concerns, radiologists use a protocol known as the ALARA principle, short for As Low As Reasonably Achievable. It's meant to keep CT dose factors low to minimize risk while maintaining maximum diagnostic benefit.
Patients are advised to ask their doctors if another diagnostic exam could be used instead of a CT scan. Ultrasound and MRI, for example, do not emit the same sort of harmful radiation. Manufacturers have added adjustable dosage settings on the CT scanning equipment that take into account a patient's size and weight. Patients should inquire if technicians operating the machines are trained to minimize radiation exposure while still providing accurate images.
I have heard the radiation from a CT scan is the same as 700 chest X-Rays. No level of radiation was given. If this is true do you think the people that make the CT scanners want you to know this?
Lyme disease? Fibromyalgia?
The technetium heart scan is not dangerous. The technetium is completely gone from the body within a few days of the test. The scan itself exposes the patient to about the same amount of radiation as a chest x ray.
The information after the word "Findings" would mean the Radiologist's interpretation of the CT scan.
Doesn't it make you wonder why these radiation questions have not been answered??

Radiography
CT Scan. Ultra sound. Xray.
No, you will need a CT (CAT Scan)
Ultrasound, CT scan, And the main one that measures the intake and output is the HIDA scan.
The DEXA bone scan exposes the patient to only a small amount of radiation-about one-fiftieth that of a chest x ray, or about the amount you get from taking a cross-country airplane flight.
The technetium heart scan is not dangerous. The technetium is completely gone from the body within a few days of the test. The scan itself exposes the patient to about the same amount of radiation as a chest x ray.

i would have to say about 80,000 dollars

Depends. 3D x-ray could mean CT scan, but there are many scans that are 3D. Around $1000 privately for a plain CT scan.
