Absorption of the x-ray beam is called
- A.
Scatter Radiation
- B.
Absorption
- C.
Attenuation
- D.
Remnant radiation
Correct Answer
C. AttenuationExplanation
Attenuation refers to the process of reducing the intensity of a beam of x-rays as it passes through a material. When an x-ray beam encounters a substance, some of the x-rays are absorbed by the material, while others may be scattered or pass through unaffected. However, in this case, the term "absorption" specifically refers to the phenomenon of the x-ray beam being absorbed by the material it encounters. Therefore, "attenuation" is the correct answer to describe the absorption of the x-ray beam.Rate this question:

- D.
CAT Scan
Correct Answer
A. Computed radiographyExplanation
Computed radiography (CR) is a type of medical imaging technique that uses a flexible plate coated with a photostimulable phosphor. When exposed to x-rays, the phosphor stores the energy from the radiation. The plate is then processed using a laser scanner, which releases the stored energy as light. This light is converted into a digital image that can be viewed on a computer screen. CR is often referred to as filmless because it eliminates the need for traditional x-ray film. It is commonly used in conjunction with other imaging modalities like CT, MRI, and CAT scan to provide detailed and accurate diagnostic images.Rate this question:

Correct Answer
B. BUN and CreatinineExplanation
BUN (blood urea nitrogen) and creatinine are two values that are commonly measured in blood work to assess kidney function. BUN is a waste product that is filtered by the kidneys, and an elevated level may indicate kidney dysfunction. Creatinine is a waste product produced by muscles and is also filtered by the kidneys. An elevated creatinine level can be a sign of impaired kidney function. Therefore, monitoring these two values can provide important information about the health of the kidneys.Rate this question:

Correct Answer
A. It is a test that highlights and evaluates the arteries in the body. It can examine arteries in the brain,neck, chest and abdomen.Explanation
An MRA (Magnetic Resonance Angiography) is different from an MRI (Magnetic Resonance Imaging) because it specifically focuses on highlighting and evaluating the arteries in the body, including those in the brain, neck, chest, and abdomen. While an MRI can also capture images of arteries, it is not specifically designed for this purpose. Additionally, an MRI can show the movement of blood flow, whereas an MRA does not provide this information.Rate this question:
