The person accredited with the initial descovery of x ray is
- Dr. Otto Walkhoff
- William D. Coolidge
- Wilhelm Conrad Roentgen
- Thomas alva Edison
- Dr. C. Edmond Kells
Correct Answer

A. Wilhelm Conrad Roentgen

Explanation

Wilhelm Conrad Roentgen is credited with the initial discovery of X-rays. In 1895, while conducting experiments with cathode rays, Roentgen noticed a fluorescent glow coming from a nearby screen. He deduced that this glow was caused by a new type of ray that was being emitted from the cathode tube. Roentgen called these rays "X-rays" due to their unknown nature. He went on to conduct further experiments and published his findings, which revolutionized the field of medicine and led to the development of X-ray imaging technology.

Which of the following is true about contrast examinations?
- Myelography performed by injecting contrast into epidural space
- Angiography can only be performed in the intra-arterially
- Contrast medium can be mixed with air or water
- Sinogram is a contrast study for the frontal sinuses
Correct Answer

A. Contrast medium can be mixed with air or water

Explanation

Contrast examinations involve the use of a contrast medium, which can be mixed with air or water. This allows for better visualization of certain structures or organs during imaging procedures. The other options are incorrect because myelography is performed by injecting contrast into the subarachnoid space, angiography can be performed intra-arterially or intravenously, and a sinogram is a contrast study for the paranasal sinuses, not just the frontal sinuses.

Structures closer to the x-ray film appear larger
- True
- False
Correct Answer

A. False

Explanation

Structures closer to the x-ray film do not appear larger. In fact, the opposite is true. When an object is closer to the film, it appears smaller in the x-ray image. This is because the x-rays diverge as they pass through the object, causing the image to be magnified when the object is further away from the film. So, the correct answer is false.

Which of the following modalities can be used to determine flow velocities through vasculature?
- MRI
- Ultrasound
- Spiral CT
- Teleradiology
Correct Answer

A. Ultrasound

Explanation

Ultrasound can be used to determine flow velocities through vasculature because it uses sound waves to create images of the blood vessels and measure the speed at which blood is flowing. This non-invasive modality allows for real-time visualization and measurement of blood flow, making it an effective tool in diagnosing and monitoring vascular conditions. MRI and Spiral CT can provide detailed images of the blood vessels but may not directly measure flow velocities. Teleradiology is a method of transmitting radiological images for interpretation and does not directly determine flow velocities.

Correct Answer

A. False
22.

Which of the following modalities can be used to determine flow velocities through vasculature?
- MRI
- Ultrasound
- Spiral CT
- Teleradiology
Correct Answer

A. Ultrasound

Explanation

Ultrasound can be used to determine flow velocities through vasculature. Ultrasound uses high-frequency sound waves to create images of the body's internal structures, including blood vessels. By analyzing the Doppler shift in the frequency of the reflected sound waves, ultrasound can measure the speed and direction of blood flow in the vasculature. This information is valuable for diagnosing conditions such as blood clots, narrowing of blood vessels, and evaluating the effectiveness of treatments. MRI and Spiral CT can also provide information about blood flow, but ultrasound is specifically known for its ability to assess flow velocities in the vasculature. Teleradiology is not a modality used for determining flow velocities through vasculature.
