CT Scan Imaging

In layman’s terms, a CT scanner is essentially an X-ray machine that is connected to a computer. The machine takes a cross-sectional picture around the patient’s body as it rotates. It utilized radiation to capture the images and needs to be done quickly to keep the exposure to radiation at a minimum.

What Are the Advantages of a CT Scan?

One of the biggest benefits of having a CT scan is that the machine can capture an image from head to toe within just a few seconds. They’re extremely useful for detecting and supporting the diagnosis of cancer, and monitoring if cancer treatments are working successfully.

CT Scan Versus MRI

What’s the Major Difference Between the Imaging Techniques?

A CT scan uses X-rays and collected data to form three dimensional images. The images will reveal any abnormalities in bone and tissues by use of radiation. A MRI captures pictures of the water molecules in the body and uses a coil as an antenna for the radio frequencies.

How Long Does Each Imaging Sequence Take?

The time frame for an MRI is normally at least 30 minutes whereas a CT is about 5 minutes. This timing is also due to the radiation the patient will be exposed to while they’re in the machine.

Which Imaging Technique is Best?

Each machine is used to examine different parts of the body. Although they both provide a look into the body, a CT is great for viewing organs and the detail in bones, and a MRI is better suited for soft tissue viewing. A physician may recommend a MRI if she or he needs to see a tumor, but ultimately, it’s a game of balancing the risks and benefits of each.
