How to Use the ARRT Computed Tomography Practice Test

Our practice tests offer the ultimate flexibility to study whenever, wherever, and however you choose. We offer three modes to engage with your ARRT Computed Tomography practice exam:

  1. Timed Mode: Take a practice test in the timed mode to mimic the experience you will have on test day.

  2. Untimed Mode: Our untimed practice tests. Use this function to evaluate your knowledge without the added pressure of a ticking timer.

  3. Study Guide Mode: Our unique study guide function shows the in-depth explanations for each practice exam question as you work through the test. Use this version to work through the questions at your own pace and take detailed notes on the answers.
Need to pause while taking one of our practice tests? No problem! Whichever mode you use, you can pause and resume it at your leisure. When you continue the test, you will pick up exactly where you left off. If you are taking a timed practice test, you will have the same amount of time left to work through the remaining ARRT Computed Tomography practice exam questions once you resume.

Once you have completed a practice exam, you will have permanent access to that exam's review page which includes a detailed explanation for each practice test question. Are you confused by a particular question on the practice test you just completed? Simply come back to it after you have completed it and get a detailed explanation of what the correct answer is and why.

Unlike other study tools, practice exams offer the unique benefit of helping you chart your progress and improvement. Start your ARRT Computed Tomography exam preparation by taking a practice test to assess your baseline expertise and existing test-taking skills. Then, use your results to identify which topics and skills need the most improvement, and create a study plan that targets those areas. As you study from books, notes, exam flashcards, or other methods, take additional practice tests at regular intervals to evaluate how you retain the information.

ARRT Computed Tomography - Why Exam Edge Sample Questions

How long does it typically take for cancer to set in after damage resulting from CT scanning?

Correct Answer:
10 – 20 years


the question pertains to the duration it typically takes for cancer to develop following exposure to radiation from a ct (computed tomography) scan. ct scans, which use x-rays to create detailed images of the inside of the body, involve a certain level of ionizing radiation. this type of radiation has the capability to damage dna, potentially leading to mutations that may result in cancer.

it is important to clarify that the risk of developing cancer from a single ct scan is generally considered low. however, the cumulative effects of radiation exposure can increase the risk, particularly with multiple scans over time or high-dose procedures. the development of radiation-induced cancer typically does not occur immediately after exposure. instead, there is a latency period before cancer becomes detectable.

the latency period for radiation-induced cancers, particularly those potentially induced by diagnostic imaging like ct scans, is estimated to range from 10 to 20 years. this wide range is due to various factors including the type of radiation, the dose received, the specific tissues exposed, and individual susceptibility. for instance, rapidly dividing tissues and organs, such as those found in children, are more sensitive to radiation effects, potentially leading to a shorter latency period in younger populations.

moreover, the assessment of cancer risk associated with radiation from ct scans is based on models and data derived from other radiation-exposed populations, such as atomic bomb survivors and patients treated with radiotherapy. these models are used to estimate the risk because direct evidence from ct scan exposure and subsequent cancer development is limited and difficult to study due to the long latency period.

in summary, while there is a recognized potential for ct scans to contribute to the development of cancer, this effect typically manifests 10 to 20 years after the exposure. it is essential for healthcare providers to weigh the benefits of diagnostic clarity provided by ct scans against the long-term risks of radiation exposure, especially in scenarios involving multiple scans or vulnerable populations.

In which of the following ways could the viscosity of contrast media be reduced?

Correct Answer:
warm it.


the viscosity of contrast media, specifically iodinated contrast media, is an important factor in medical imaging procedures such as computed tomography (ct) scans and angiography. viscosity refers to the thickness or internal resistance to flow of a liquid. the higher the viscosity, the thicker the liquid is, and the more difficult it is to inject through a syringe or catheter. managing the viscosity of contrast media is crucial for ensuring efficient and safe administration to patients.

one effective method to reduce the viscosity of contrast media is by warming it. typically, contrast media can become more viscous, or thicker, when stored at room temperature or if it is cooled. this increase in viscosity can make the media harder to handle and inject, potentially leading to complications such as slower injection rates or increased pressure during injection, which can be uncomfortable for patients.

warming the contrast media to body temperature, or approximately 37 degrees celsius, is a practical approach to decrease its viscosity. when the media is warmed, the molecules within it gain kinetic energy and move more freely, thereby reducing internal resistance and making the liquid less thick. this reduction in viscosity facilitates smoother and faster injection, improving the flow rate through syringes and catheters. additionally, it can enhance patient comfort and the overall ease of the procedure for healthcare professionals.

it is important to note that other methods such as refrigerating or freezing the contrast media are not effective for reducing viscosity. in fact, these methods would increase the viscosity, making administration more difficult. similarly, while storage in a heated place might seem like a solution, care must be taken to ensure the media is not overheated, as excessive heat could potentially degrade the quality of the contrast agent or alter its chemical properties.

in conclusion, warming the contrast media to body temperature is the most advisable and effective strategy to reduce its viscosity, thereby ensuring efficient administration and enhancing both patient safety and comfort during medical imaging procedures. proper handling and temperature management are key to maintaining the optimal performance of contrast media in clinical settings.
