An MRI is highly adept at capturing images that help doctors determine if there are abnormal tissues within the body. MRIs are more detailed in their images.

What is a drawback to using a CT scan?

Disadvantages of computerised tomography scanning CT scans of the brain can be affected by bone nearby. High doses of radiation are involved in CT scanning – chest CT scan is equivalent to 350 chest X-rays; CT abdomen to 400 chest X-rays and CT pulmonary angiography 750 chest X-rays.

What Cancer Can a CT scan detect?

CT scans can detect bone and joint problems, like complex bone fractures and tumors. If you have a condition like cancer, heart disease, emphysema, or liver masses, CT scans can spot it or help doctors see any changes.

Is a CT scan or MRI better for detecting cancer?

CT and MRI scans can show tissue abnormalities that are likely tumors but it is not a definitive diagnostic tool for cancers. The images produced by both CT and MRI scans can be used to determine the best site to do a biopsy to definitively diagnose cancer.
