A CT scan is generally good for larger areas, while an MRI scan produces a better overall image of the tissue under examination. Both have risks but are relatively safe procedures.
What is the most detailed medical scan?
A CT scan , or computed tomography scan, sends radiation through the body. However, unlike a simple X-ray study, it offers a much higher level of detail, creating computerized, 360-degree views of the body’s structures. CT scans are fast and detailed. They take longer than X-rays but are still fast (about one minute).
