CT and MRI are two distinct forms of medical imaging that produce pictures of organs and tissues within your body. Although CT and MRI have some differences, they also differ from each other. Since they are different, physicians can opt to use one form of imaging over another.

Both MRIs and CTs are painless and non-invasive, and both can assist your physician in diagnosing and treating an illness. Both of these tests require you to lie on a table that then moves into a scanner. You will need to hold very still throughout both tests so the scan will be able to get good pictures. In CT and MRI, the technician does leave the room, but you can still speak with the person using an intercom connection.

CTs and MRIs make images differently. A CT scan builds a couple of images, or “slices,” using x-rays from various angles. An MRI scan builds images through magnetic fields and radio waves. There are several other significant differences between the two medical imaging technologies.

About CT Scans

CT stands for computed tomography. CT scans are also called computerized axial tomography, or CAT scans.

In a CT, you’ll be lying on a moving table that goes through a big, doughnut-shaped scanner. A computer fuses information gathered to form 3-dimensional images of your bones and soft tissue.

Physicians order CT scans when they are seeking out or assessing:

• Head injury
• Bone breaks
• Pneumonia
• Bleeding within the body
• Internal organ issues
• Tumors
• Cancer development or the success of cancer treatment as a result

About MRI Scans

Magnetic resonance imaging, or MRI scan, is great at providing images of soft tissue, organs, or ligaments, and it makes your doctor’s life simpler to be able to spot abnormal tissue, soft tissue injuries, torn ligaments, bulging disks, and so forth.

As with the CT scan, you will be lying on a table for the MRI. The MRI machine itself is similar to a donut shape, but thicker. MRIs are also very loud, and you may be given earplugs or headphones to muffle the noise.

Physicians can also prescribe MRIs in place of CTs if they require producing more precise and detailed images. Physicians tend to order MRI scans for diagnosing bone, joint, and organ problems, particularly those involving the:

• Brain
• Breasts
• Heart
• Arteries
• Veins
• Joints
• Wrists
• Ankles

Physicians can also prescribe MRIs in place of CT scans if they have suspected certain conditions, including:

• Soft tissue problems
• Torn ligaments
• Herniated disks
• Comparing the Risks of MRI Scans and CT Scans

Both CT scans and MRI do carry some risk, based on the kind of imaging and the quality of the imaging.

One of the biggest differences between the two scans is that CT scans use a very small amount of ionizing radiation, while MRI does not utilize radiation. Ionizing radiation that CT scans emit can influence biological tissue, but as per the National Institute of Biomedical Imaging and Bioengineering, cancer risk due to exposure to CT scan radiation is usually minimal. In addition, x-rays and CT scans are not safe when a woman is pregnant, so doctors can request an MRI instead.

Since MRIs involve the use of strong magnets, anything metallic at all in the body, including metal plates, rods and screws, is dangerous. Metal implants could shift or overheat when put in the presence of the magnetic fields of an MRI.

Risk of CT Scans Are:

• Harm to unborn children
• Being exposed to a very small amount of radiation
• Possible bad reaction to contrast dyes administered

Risk of MRIs Are:

Possible effects to metals in the body by magnets during MRI

Loud and startling machine noises and even induce hearing problems

A rise in body temperature after prolonged MRIs

Claustrophobia

You must see a doctor before an MRI if you have some implants, such as:

• A pacemaker
• Artificial joints
• An IUD
• Eye implants

Physicians have CT scans done more frequently since CT scans cost less than MRI but still make good images. CTs are quieter than MRIs too. CT scan is quicker and can create generalized images of tissue, organs, and bone structure; MRIs take longer, but are better pictures.

Q. Are MRI and CT scans harmful?

There are no direct side effects of MRI and CT scan, if you’ve followed all the precautions and followed your providers guidelines and advice. You might feel some discomfort but it will be temporary for which no mediations or extra care is needed, but if you feel any allergic reaction consult with your doctor immediately.

If your doctor needs to figure out what’s going on inside your body and keep track of different illnesses, the medical imaging technique is the best tool to figure it out. There are two common ways they used to do this are CT scans and MRI scan. Picking up the right one is key to getting a clear and accurate diagnosis. In this article, we will understand or take a more clear view of when CT and MRI scans are the best choice. Here at CareBox, we’re proud to offer advanced imaging services, including CT scan, to help patients get the right answers they need.

What is a CT Scan?

CT scan, or computed tomography scan, is a technique used to take detailed cross-sectional images of your body using X-rays and a computer. These images provide doctors and healthcare professionals a broad view of your abnormality and help them spot internal problems and plan the best way to treat and diagnose the diseases.

What’s Great About CT Scans

Here are some reason why CT scans are so frequently used is because they have a lot going for them such as- 

• Fast and Efficient: CT scans are a more quick and painless procedure, which is a big advantage in emergency situations when time is critical for figuring out the abnormality.
• Excellent for Bones and Tissues: Ct scan is beneficial to visualize bones, soft tissues, and blood vessels, making them perfect for finding broken bones, tumors, and internal bleeding etc.

Limitations of CT Scan

Ct scan is best in all ways, but here are some drawbacks of CT scan which you need to understand for your overall well being and it will help you to prepare according to it.

• Uses Radiation: CT scans use X-rays, which means you’re going to experience a small amount of radiation. While generally it is considered safe, getting many scans can increase the risk.
• Soft Tissues Can Be Less Clear: In comparison to MRI scans, CT scans might fail to  show soft tissues in as much detail, which makes CT scan less ideal for certain conditions.
• Not Always Right for Everyone: Because of the radiation, CT scans aren’t recommended for pregnant women unless in necessary conditions. Also, people with metal implants and pacemakers might not be able to get a CT scan.

What is MRI Scan?

MRI scans, or magnetic resonance imaging scans use strong magnets and radio waves to create detailed pictures of body organs, soft tissues etc. MRI scan is especially good at providing the fine details of soft tissues like the brain, spinal cord, and joints.

What Makes MRI Scans Special?

MRI scan have some unique advantages like they’re helpful in providing the broader view of soft tissues, and others we’re going to look- 

• Amazing Soft Tissue Detail: MRI provides clear pictures of soft tissues, making it easier to see severe problems and injuries clearly.
• No Radiation Involved: As MRI scan doesn’t use radiations, which makes them a safer option for repeated scans.
• Great for Brains, Spines, and Joints: They’re useful for looking at neurological disorders, spinal cord injuries, and issues with joints.

Things you should keep in mind about MRI Scans

MRI scans also have some limitations:

• Takes longer: MRI scans usually take more time than CT scans procedure, from 15 minutes to an hour or even longer time to complete, depending on what’s being looked at. This can be tough for people who have trouble staying still.
• Can be Uncomfortable The MRI machine is a bit like a tunnel or closed bore, which can make some people feel claustrophobic (Those who have a fear of closed spaces). Also, people with certain medical devices like pacemakers might not be able to have an MRI, as this can be harmful for them.
• Generally more expensive: MRI scans are more expensive than CT scans.

CT Scans Versus MRI Scans: What’s the Difference?

Image Clarity and Detailing

When we compare how clear and detailed the pictures are from CT and MRI scans, it depends on what we’re looking at. CT scans are fantastic for seeing bones clearly, making them the go-to for finding fractures, tumors in bones, and checking the overall health of your skeleton. The sharp detail in CT scans is really helpful in emergencies and for bone-related problems.

On the other hand, MRI scans are the champions when it comes to soft tissues. They can really show the subtle differences in organs like the brain, liver, kidneys, and reproductive system. This makes MRI especially useful for diagnosing things like tumors, multiple sclerosis, and problems with blood vessels. The ability to tell different soft tissues apart so well makes MRI a very accurate way to diagnose certain conditions.

Radiation and Safety

When choosing an imaging method, safety is a big concern. CT scans use X-rays, which do involve some exposure to radiation. While the amount of radiation in a CT scan is generally considered safe, it’s still important to avoid unnecessary exposure, especially if you need multiple scans. This is particularly important for children and young adults who are more sensitive to radiation.

MRI scans, however, don’t use any radiation at all. This makes them a safer option, especially for people who need repeated scans or for pregnant women. MRI can be done at any point during pregnancy without worrying about harming the baby.

When to Use Which Scan

Whether a CT or MRI scan is the better choice really depends on the specific medical issue being investigated. Sometimes, both types of scans can be helpful in getting a full picture of what’s going on.

Making the Right Choice:

Deciding between a CT scan and an MRI scan involves considering a few things:

• Your Medical History: Doctors need to know about your past health issues, allergies, previous surgeries, or any medical devices you have, as this can influence which scan is best.
• What Needs to Be Diagnosed: The specific medical problem your doctor is trying to figure out will guide the choice of scan. Whether they need a detailed look at bones, soft tissues, or specific organs will help determine if a CT or MRI is more appropriate.
• Your Comfort and Safety: Your comfort and safety are important. If you’re very claustrophobic or have trouble lying still for a long time, an MRI might be difficult. In those cases, a CT scan might be a better option.
