Why would a doctor order a CT scan?
Your doctor may recommend a CT scan to help: Diagnose muscle and bone disorders, such as bone tumors and fractures.
Pinpoint the location of a tumor, infection or blood clot.
Guide procedures such as surgery, biopsy and radiation therapy..
What is a drawback to using a CT scan?
In general, a CT scan has the advantage of short study time (15 to 20 minutes) with high quality images. However, disadvantages include the need for ra- diation exposure and the use of a contrast material (dye) in most cases, which may make it inappropriate for patients with significant kidney problems.
Can I request MRI instead of CT scan?
Doctors might order MRIs instead of CTs when they need to create more accurate and detailed images. Physicians typically order MRI scans to diagnose issues with bones, joints, and organs, especially those that affect the: Brain.
Can I refuse a CT scan?
You should never refuse a test if it’s needed. But they’re often not. Ask why the test is being done, how the results will affect your treatment, and what will happen if you skip it.

Minor reactions to the IV contrast used for CT scan may include nausea, vomiting, headache or dizziness, which are usually of short duration and usually require no treatment.
When should I buy a CT or MRI?
For most musculoskeletal issues, MRI is the imaging procedure of choice. CT Head without contrast for initial evaluation of trauma/hemorrhage. MRI Brain with and without contrast for evaluation of infection, inflammation and neoplasm. If MRI contraindicated then a CT Head with and without contrast.
How do you know if you need a CT scan?
Often, CT scans aren’t necessary. CT scans can show if there is swelling or bleeding in the brain or a fracture in the skull. If you have signs of a serious injury, a CT scan is usually the best first test to diagnose it. Your health care provider will look for specific signs of a more serious problem.
What is the alternative to a CT scan?
Still, the most common alternatives to CT scans are ultrasounds and MRIs. Unlike CT scans, neither uses ionizing radiation. Ultrasound constructs a picture using sound waves; MRI uses magnetic fields to produce an image that often has greater clarity than a CT.
Which is better CT scan or MRI?
Magnetic resonance imaging produces clearer images compared to a CT scan. In instances when doctors need a view of soft tissues, an MRI is a better option than x-rays or CTs. MRIs can create better pictures of organs and soft tissues, such as torn ligaments and herniated discs, compared to CT images.
How many CT scans can you have in a lifetime?
The more scans you have, the higher your lifetime exposure and therefore the higher your risk. The American College of Radiology recommends limiting lifetime diagnostic radiation exposure to 100 mSv. That is equal to 10,000 chest x-rays, or up to 25 chest CTs.
How accurate are CT scans?
CT scans can produce false negatives and false positives. CT scan can miss cancer, or miss tumors in other areas of the body. CT scans are proven to be less effective at diagnosing cancer than PET/CT.
Is it worth getting a CT scan?
Since CT scans can image bones in a very clear manner, CT scans prove to be extremely valuable to doctors who are examining patients for bone injuries in places like their hands and their feet, as well as in their spinal region. These areas might not be as visible with diagnostic imaging methods like x-rays.
Is CT scan painful?
Will It Hurt? CT scan is a painless exam. Patients who are receiving Intravenous Contrast Dye (also known as IVP Dye) may experience a warm sensation, metallic taste, and or the feeling of urination.
Are CT scans expensive?
Range of Costs In general, you can expect to see CT scan costs that range from $270 on the very low end to nearly $5,000 on the high end. The cost varies depends on the facility, your location, and factors such as whether you pay in cash or bill your insurance provider.
Can a CT scan tell if a tumor is benign?
Many internal benign tumors are found and located by imaging tests, including: CT scans. MRI scans. mammograms.
