Explanation

Arthrography can be used to diagnose a variety of joint problems, including arthritis, tendonitis, and ligament tears. It can also be used to evaluate the extent of damage to a joint after an injury.

Multiple choice

How is arthrography performed?

  1. A contrast agent is injected into the joint and then X-rays are taken.

  2. A small incision is made in the joint and a camera is inserted.

  3. A needle is inserted into the joint and fluid is withdrawn.

  4. A tourniquet is placed around the joint and blood flow is restricted.

A Correct answer
Explanation

Arthrography is a minimally invasive procedure that involves injecting a contrast agent into a joint and then taking X-rays. The contrast agent helps to highlight the structures inside the joint, making them more visible on the X-rays.

Multiple choice

What are the risks of arthrography?

  1. Infection

  2. Bleeding

  3. Nerve damage

  4. All of the above

Reveal answer Fill a bubble to check yourself

Multiple choice

What is the primary purpose of myelography?

  1. To visualize the spinal cord and nerve roots

  2. To diagnose brain tumors

  3. To detect kidney stones

  4. To evaluate blood flow in the heart

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Myelography is a diagnostic imaging procedure that uses a contrast agent to visualize the spinal cord and nerve roots. It is commonly used to diagnose conditions such as herniated discs, spinal stenosis, and tumors.

Multiple choice

Which contrast agent is typically used in myelography?

  1. Iodine-based contrast agent

  2. Gadolinium-based contrast agent

  3. Barium sulfate

  4. Air

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Iodine-based contrast agents are commonly used in myelography because they provide good visualization of the spinal cord and nerve roots. Gadolinium-based contrast agents are also sometimes used, but they are more likely to cause side effects.

Multiple choice

How is the contrast agent administered in myelography?

  1. Orally

  2. Intravenously

  3. Through a spinal tap

  4. Through a skin injection

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

In myelography, the contrast agent is typically administered through a spinal tap. A needle is inserted into the spinal canal, and the contrast agent is injected into the cerebrospinal fluid (CSF).

Multiple choice

What is the role of the cerebrospinal fluid (CSF) in myelography?

  1. It helps to distribute the contrast agent throughout the spinal canal

  2. It provides a natural contrast between the spinal cord and nerve roots

  3. It helps to reduce the risk of side effects from the contrast agent

  4. It helps to improve the quality of the images

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The CSF helps to distribute the contrast agent throughout the spinal canal, ensuring that all areas of the spinal cord and nerve roots are visualized.

Multiple choice

What type of imaging modality is used in myelography?

  1. X-ray

  2. Magnetic resonance imaging (MRI)

  3. Computed tomography (CT)

  4. Ultrasound

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Myelography is typically performed using X-ray imaging. X-rays are able to visualize the contrast agent as it flows through the spinal canal and around the spinal cord and nerve roots.
