There are several ways to scan muscles, including CT scans, ultrasounds, and advanced MRI techniques. CT scans are more detailed than general X-rays, showing images of the bones, muscles, fat, and organs. Ultrasounds use sound waves to produce pictures of muscles, tendons, ligaments, nerves, and joints. Advanced MRI techniques can provide information on the composition, microstructure, and function of muscles or groups of muscles.

| How it works | CT scans use detailed images of the body, including bones, muscles, fat and organs. MRI scans can provide information on composition, microstructure and function of muscles. Ultrasound uses sound waves to produce pictures of muscles, tendons, ligaments, nerves and joints. |
| Preparation | For a CT scan, a dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. For an ultrasound, the patient is positioned lying face-up or face-down on an examination table and may be asked to move the extremity being examined. |

What You'll Learn
CT scans
A CT scan may be done with or without "contrast". Contrast refers to a substance taken by mouth or injected into an intravenous (IV) line that causes the particular organ or tissue under study to be seen more clearly. Contrast examinations may require you to fast for a certain period of time before the procedure. Your physician will notify you of this prior to the procedure.
In standard X-rays, a beam of energy is aimed at the body part being studied. A plate behind the body part captures the variations of the energy beam after it passes through skin, bone, muscle, and other tissue.

MRI scans
These scans are often used in a clinical research setting to study muscle pathology such as muscular dystrophy and other myopathies. Some of the techniques used in MRI scans are widely available on clinical scanners, such as T2 mapping, proton MR spectroscopy, and fat-water separation techniques.
Other techniques, such as diffusion-tensor imaging (DTI), phosphorus MR spectroscopy, and MR elastography, require special software and hardware and are not as widely available in clinical practice. However, these techniques have the potential to provide even more detailed assessments of muscle function, composition, and microstructure.

Ultrasound scans
During the procedure, the patient is positioned lying face-up or face-down on an examination table. The radiologist or sonographer may ask the patient to move the extremity being examined or may move it for them to evaluate the anatomy and function of the joint, muscle, ligament or tendon.

X-rays
To get a clearer image of the muscles, a dye may be injected into a vein or swallowed. This substance, known as "contrast", causes the particular organ or tissue under study to be seen more clearly. However, CT scans are more detailed than general X-rays and provide greater clarity and reveal more details about the muscles and other body parts.

Contrast examinations
Ultrasound imaging is another way to scan muscles. Ultrasound uses sound waves to produce pictures of muscles, tendons, ligaments, nerves, and joints. It is used to help diagnose sprains, strains, tears, trapped nerves, arthritis, and other musculoskeletal conditions. For an ultrasound examination, the patient is positioned lying face-up or face-down on an examination table. The radiologist or sonographer may ask the patient to move the extremity being examined or may move it for them to evaluate the anatomy and function of the joint, muscle, ligament, or tendon.
Advanced MRI techniques for muscle assessment are also available and can provide information on the composition, microstructure, and function of muscles or groups of muscles. Some of these techniques are widely available on clinical scanners, while others require special software and hardware and are not widely available in clinical practice.

Frequently asked questions
CT scans are more detailed than general X-rays, showing images of the bones, muscles, fat, and organs. They also minimise exposure to radiation.
Ultrasound imaging uses sound waves to produce pictures of muscles, tendons, ligaments, nerves, and joints. It is safe, non-invasive, and does not use ionising radiation.
MRI scans are advanced techniques for muscle assessment that can provide information on composition, microstructure, and function.
MRI scans are more advanced than CT scans and can provide more detailed information on muscle composition, microstructure, and function.
For an ultrasound, you may be asked to wear a gown and lie face-up or face-down on an examination table. For a CT scan, you may need to fast for a certain period of time beforehand if a contrast examination is required.
