Try these 12 questions from different topics. Open "Show answer" to check yourself and read the explanation.

1. Question 1 · Radiographic Technique & Positioning

   The projection with which the side view of any anatomical part is demonstrated during any radiographic procedure is known as ……………

   1. A.Oblique
   2. B.A.P
   3. C.Lateral
   4. D.P.A
   Show answer

   Answer: C. Lateral

   A lateral projection shows the side view of an anatomical part (the x-ray beam passes from one side to the other).

2. Question 2 · Radiation Physics & Radiobiology

   Using the collimator while performing a chest radiography makes you ……………… I. Increase the exposure to the patient II. Reduce scatter radiation III. Increase image quality

   1. A.I only
   2. B.I and III only
   3. C.I and II only
   4. D.II and III only
   Show answer

   Answer: D. II and III only

   Collimation narrows the beam, reducing scatter (II) and thereby improving image quality (III); it lowers, not raises, patient exposure.

3. Question 3 · General / Mixed

   Which of the following is a clinical indication for cervical spine radiography? I. Trauma II. Spondylosis III. Numbness IV. Paraplegia or Quadriplegia

   1. A.I only
   2. B.I and III only
   3. C.I, II, and III
   4. D.I, II, III, and IV
   Show answer

   Answer: D. I, II, III, and IV

   Trauma, spondylosis, numbness and paraplegia/quadriplegia are all valid clinical indications for cervical spine imaging.

4. Question 4 · Radiographic Anatomy

   The carpal bone(s) with which the radius articulates to form the radiocarpal joint is/are I. Scaphoid II. Lunate III. Capitate

   1. A.I only
   2. B.II only
   3. C.I and II only
   4. D.I, II, and III
   Show answer

   Answer: C. I and II only

   The radius articulates with the scaphoid and lunate to form the radiocarpal (wrist) joint; the capitate is more distal.

5. Question 5 · Image Processing & Film

   On a film radiograph, an area of high density in the human body will appear

   1. A.Lighter than the surrounding area
   2. B.Darker than the surrounding area
   3. C.More defined than the surrounding area
   4. D.Less defined than the surrounding area
   Show answer

   Answer: A. Lighter than the surrounding area

   High-density (radiopaque) structures such as bone attenuate more x-rays, so they appear lighter/whiter on the film.

6. Question 6 · Pathology

   If someone has a Pott's fracture, what type of radiograph should be taken for the patient?

   1. A.A.P ankle
   2. B.Lateral knee
   3. C.A.P knee
   4. D.Lateral ankle
   Show answer

   Answer: D. Lateral ankle

   A Pott's fracture is an ankle injury, best shown with a lateral (and AP) ankle projection.

7. Question 7 · Quality Assurance & Safety

   All activities that the management of a radiography unit carries out in an effort to implement their quality policy are known as…………………..

   1. A.Quality Management
   2. B.Quality Control
   3. C.Quality assurance
   4. D.Quality monitoring
   Show answer

   Answer: A. Quality Management

   These implementation activities constitute Quality Management.

8. Question 8 · Professional Practice & Regulation

   Which of the following is/are aim(s) of the Code of ethics in radiography? I. To serve as a guide by which radiographers can evaluate their professional conduct II. To assist radiographers in maintaining a high level of ethical conduct III. To give radiographers knowledge of their patients’ rights

   1. A.I only
   2. B.II only
   3. C.I and II only
   4. D.I, II and III
   Show answer

   Answer: C. I and II only

   The code of ethics guides conduct and protects the patient (I and II).

9. Question 9 · Physiology

   A patient with epigastric pain reports to the Radiology department for abdominal ultrasound. Which of the following organs of the digestive tract is most likely involved? I. Liver II. Stomach III. Gall bladder

   1. A.I only
   2. B.II only
   3. C.I and III only
   4. D.I, II and III
   Show answer

   Answer: D. I, II and III

   Epigastric pain relates to the stomach and adjacent upper-abdominal structures (all listed).

10. Question 10 · Radiotherapy

    What term describes critical structures in or near the treatment field?

    1. A.Internal target volume
    2. B.Organs at risk
    3. C.Irradiated volume
    4. D.Internal margin
    Show answer

    Answer: B. Organs at risk

    Organs at risk (OAR) are normal tissues whose radiosensitivity may significantly influence planning or the prescribed dose.

11. Question 11 · MRI Physics

    Routinely, double-echo imaging provides:

    1. A.MR angiograms
    2. B.PD for anatomy, T1 for pathology
    3. C.PD for anatomy, T2 for pathology
    4. D.T1 for anatomy, T2 for pathology
    Show answer

    Answer: C. PD for anatomy, T2 for pathology

    Double-echo yields a PD-weighted (anatomy) and a T2-weighted (pathology) image from one sequence.

12. Question 12 · CT / Specialized

    The reduction in intensity of the CT x-ray beam as it passes through tissue is termed:

    1. A.isotropy
    2. B.attenuation
    3. C.absorption
    4. D.photodisintegration
    Show answer

    Answer: B. attenuation

    Attenuation = the overall loss of beam intensity (absorption + scatter).
