Myth: CT scans cause cancer. Truth: A single CT scan does not cause cancer. Repeated CTs, however, can increase your risk over time.
Is a CT scan or MRI better for detecting cancer?
Where MRI really excels is showing certain diseases that a CT scan cannot detect. Some cancers, such as prostate cancer, uterine cancer, and certain liver cancers, are pretty much invisible or very hard to detect on a CT scan. Metastases to the bone and brain also show up better on an MRI.
What does not show up on a CT scan?
A CT scan uses X-rays, but an MRI uses magnets and radio waves. Unlike an MRI, a CT scan does not show tendons and ligaments. MRI is better for examining the spinal cord. A CT scan is better suited to cancer, pneumonia, abnormal chest x-rays, bleeding in the brain, especially after an injury.
Can stomach cancer be missed on a CT scan?
Although CT or MRI scans can make detailed pictures of the inside of the body, they can miss some tumors, especially very small tumors. Doctors might do a laparoscopy before any other surgery to help confirm the cancer is still only in the stomach and can be removed completely with surgery.
