We also know that everyone likes to study differently, so we offer three different ways to use your DHA Computed Tomography practice exams:

  • Timed DHA Computed Tomography Practice Test Mode: Timed tests are just like the DHA Computed Tomography exam. Our system sets the test time to the same time limit, or time limit per question, that you will experience with the actual exam on test day. This is a great method of practicing your pacing, especially if you're concerned about completing your exam within the time limit.

  • Untimed DHA Computed Tomography Practice Test Mode: With this option, you can take your time and thoroughly consider each question before answering. This rush-free mode is recommended for those dipping their toes into exam prep or just starting on their journey to take the DHA Computed Tomography. It is a great way to test your knowledge with no time limit and highlight blind spots you will need to come back to in your studies - one of the many advantages of taking DHA Computed Tomography practice exams with Exam Edge!

  • DHA Computed Tomography Study Guide Mode: Not sure where to even begin with your studying? Try a practice test in explanation mode. The questions act as a study guide, giving you the option to see the answers as you take the test. Study guide mode is an effective way to review the DHA Computed Tomography exam subject matter before you take the exam in a timed format. We recommend taking a practice test in explanation mode and taking thorough notes as the best method for beginning your test prep.

DHA Computed Tomography - Features Sample Questions

___________ would be considered a decrease in intensity of an x-ray beam?

Correct Answer:
attenuation


the correct answer to the question "___________ would be considered a decrease in intensity of an x-ray beam?" is "attenuation." attenuation in the context of x-ray physics refers to the reduction in intensity of the x-ray beam as it passes through materials. this decrease in beam intensity is primarily due to the absorption and scattering of photons, which are the fundamental particles of light, including x-rays.

when an x-ray beam penetrates a substance, such as human tissue in medical imaging, several interactions can occur between the x-rays and the atoms of the substance. the most significant of these interactions are the photoelectric effect and compton scattering. the photoelectric effect occurs when an x-ray photon ejects an electron from an atom, completely absorbing the photon's energy. this effect is more likely to occur with inner-shell electrons in heavier atoms, which is why materials with higher atomic numbers are better at absorbing x-rays, appearing denser on an x-ray image.

compton scattering, on the other hand, involves the x-ray photon colliding with an outer-shell electron and only part of the photon's energy being transferred to the electron. the photon itself is then scattered with reduced energy and potentially deviated from its original path. this scattering affects the clarity and contrast of the x-ray image, as scattered photons can reach the x-ray detector and contribute to image fogging.

in summary, attenuation is a critical concept in the field of radiology and medical imaging, as it influences both the quality of the diagnostic image and the radiation dose received by the patient. understanding how attenuation works, and the factors that affect it, helps in optimizing x-ray imaging techniques and improving safety and image quality.

How long after an intracranial hemorrhage (ICH) would the area appear hyperdense to the normal brain tissue?

Correct Answer:
hours to minutes


after an intracranial hemorrhage (ich), the affected brain tissue undergoes several changes that are visible on imaging studies such as a ct scan. initially, when the hemorrhage occurs, blood escapes from the ruptured blood vessel and starts accumulating in the brain tissue or the spaces around it. since fresh blood is denser than the surrounding brain tissues, this accumulated blood appears hyperdense (brighter) on a ct scan.

this hyperdense appearance of the hemorrhage on a ct scan typically occurs within minutes to hours after the event. the high density is due to the presence of hemoglobin in the blood, which has a high atomic number and thus appears brighter on the scan compared to the surrounding brain tissue.

as time progresses, the blood begins to break down through a process called hematoma resolution, involving the lysis of red blood cells and the conversion of hemoglobin into other products. approximately 3 days after the ich, the density of the hematoma on the ct scan starts to decrease as the blood cells break down and the hemoglobin dissipates.

the appearance of the hematoma continues to evolve over time. for patients who are on oral anticoagulants, the breakdown process might be altered, and the hematoma can remain hypodense (darker than the surrounding brain tissue) for a longer period. this altered appearance is due to the impaired ability of the blood to clot, which affects the consistency and the breakdown process of the hematoma.

in summary, the hyperdense appearance of an intracranial hemorrhage on a ct scan occurs within hours to minutes after the bleeding starts. this is followed by a gradual decrease in density as the blood is broken down, a process that can vary in duration depending on several factors including medical treatment like anticoagulation.
