    Which of the following is true about X rays?

    • A.

      Uses a vacuum and low potential difference

    • B.

      Denser materials cause less blackening

    • C.

      Form of electromagnetic energy with long wavelength

    • D.

      All of the above

    Correct Answer
    B. Denser materials cause less blackening
    Explanation
    Denser materials cause less blackening in X-rays because they are more effective in absorbing the X-ray photons. As X-rays pass through a material, they are absorbed by the atoms in the material. Denser materials have more atoms packed closely together, leading to more opportunities for absorption. This results in less blackening on the X-ray film or detector when denser materials are present.

    Correct Answer
    C. Contrast medium can be mixed with air or water
    Explanation
    Contrast examinations involve the use of contrast medium, which can be mixed with either air or water. This allows for better visualization of certain structures or organs during imaging procedures. Mixing contrast medium with air or water helps to highlight specific areas of interest and improve the clarity of the images obtained.

    Rate this question:

  • 4. 

    Which of the following modalities can be used to determine flow velocities through vasculature?

    • A.

      MRI

    • B.

      Ultrasound

    • C.

      Spiral CT

    • D.

      Teleradiology

    Correct Answer
    B. Ultrasound
    Explanation
    Ultrasound can be used to determine flow velocities through vasculature. Ultrasound imaging uses high-frequency sound waves to create real-time images of the blood vessels. By analyzing the Doppler effect, which involves changes in sound frequency caused by the movement of blood cells, ultrasound can measure the velocity and direction of blood flow in the vasculature. This non-invasive technique is commonly used in medical settings to assess blood flow in various parts of the body, such as the heart, arteries, and veins.

    Rate this question:

  • 5. 

    When examining the chest or musculoskeletal system, which of the following modalities would be least helpful?

    • A.

      X-ray

    • B.

      MRI

    • C.

      Spiral CT

    • D.

      Ultrasound

    Correct Answer
    D. Ultrasound
    Explanation
    Ultrasound would be the least helpful modality when examining the chest or musculoskeletal system. Ultrasound uses high-frequency sound waves to create images of the body's internal structures. While it is useful for evaluating soft tissues and organs, it is not as effective in visualizing bones and dense structures like X-ray, MRI, and Spiral CT. These modalities provide better visualization of the musculoskeletal system and can detect abnormalities such as fractures, tumors, and infections. Ultrasound is more commonly used for evaluating soft tissues, such as tendons, muscles, and organs like the heart or liver.

  • 6. 

    When choosing imaging studies, protocol should be followed for most patients in clinical practice

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The statement is false because while following a protocol is important in clinical practice, it is not necessary for most patients when choosing imaging studies. Each patient's case should be evaluated individually, taking into consideration their specific symptoms, medical history, and the suspected diagnosis. The protocol may not be applicable or optimal for every patient, and the decision on which imaging study to choose should be based on the individual patient's needs and circumstances.

    Rate this question:

  • 7. 

    Which of the following can be assessed on plain film?

    • A.

      Myocardial thickness

    • B.

      Heart size

    • C.

      Motion

    • D.

      Coronary artery disease

    Correct Answer
    B. Heart size
    Explanation
    Heart size can be assessed on plain film because a plain film, such as a chest X-ray, can provide a visual representation of the heart and its size. By analyzing the shape and dimensions of the heart on the film, healthcare professionals can determine if the heart is enlarged or within normal size range. This assessment can be helpful in diagnosing certain cardiac conditions or monitoring the progression of heart disease.

    Rate this question:

  • 8. 

    Which of the following factors and their effect on the heart's appearance are paired correctly?

    • A.

      Mediastinal shift: apparent enlargement

    • B.

      COPD: Masked enlargement

    • C.

      Scoliosis: masked enlargement

    • D.

      All of the above

    Correct Answer
    B. COPD: Masked enlargement
    Explanation
    COPD stands for Chronic Obstructive Pulmonary Disease, which is a chronic inflammatory lung disease that causes obstructed airflow from the lungs. In COPD, the lungs become hyperinflated, causing the diaphragm to flatten and push the heart downwards, giving the appearance of enlargement. This is why COPD is correctly paired with "masked enlargement" as it can hide the true size of the heart on imaging.

    Rate this question:

    • B.

      Situs inversus

    • C.

      Mediastinal shift

    • D.

      A & C

    Correct Answer
    B. Situs inversus
    Explanation
    Situs inversus is the correct answer because it is a condition in which the organs of the body are reversed or mirrored from their normal positions. In this case, it suggests that the organs in the chest cavity, including the lungs, may be reversed. This can be significant in diagnosing and treating conditions such as tension pneumothorax, which is the abnormal accumulation of air in the pleural space causing a collapsed lung. The presence of situs inversus can affect the presentation and management of conditions like mediastinal shift, where the organs in the middle of the chest are displaced. Therefore, situs inversus is a relevant consideration in this context.

    • D.

      Heart Failure

    Correct Answer
    D. Heart Failure
    Explanation
    Heart failure is the most likely diagnosis based on the given options. Hemothorax refers to blood accumulation in the pleural cavity and is not mentioned in the question. Aortic aneurysm is the abnormal dilation of the aorta, which is not related to the symptoms mentioned. Pericarditis is inflammation of the pericardium, the outer lining of the heart, which does not directly cause symptoms of heart failure. Therefore, heart failure is the most appropriate diagnosis for this patient.

    Rate this question:

  • 16. 

    This patient most likely has which of the following?

    • A.

      Hemothorax

  • 17. 

    Structures closer to the x-ray film appear larger. True or false? 

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    Structures closer to the x-ray film do not appear larger. This is because the size of the structures in an x-ray image is determined by the distance between the x-ray source, the object being imaged, and the x-ray film. The closer the object is to the film, the smaller it appears in the image. Therefore, the correct answer is false.
