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

  • Timed ARRT Computed Tomography Practice Test Mode: Timed tests are just like the ARRT 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 ARRT 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 ARRT 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 ARRT Computed Tomography practice exams with Exam Edge!

  • ARRT 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 ARRT 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.

ARRT Computed Tomography - Features Sample Questions

How can the technologist correct a ring artifact?

Correct Answer:
recalibrating the machine’s detector


in medical imaging, particularly in computed tomography (ct), artifacts can degrade the quality of images, potentially leading to misdiagnosis. among these, the ring artifact is specifically known for its appearance as concentric circles or rings in the reconstructed images. this artifact typically arises due to miscalibration or malfunction of one or more detector elements in the ct scanner.

to address a ring artifact, the technologist can take several corrective actions, with recalibrating the machine’s detector being a primary method. recalibration involves adjusting the sensitivity of each detector element so that they all respond uniformly to the x-rays. this uniform response is crucial because discrepancies in detector output can manifest as rings in the final image. by recalibrating, the technologist ensures that all the detectors are accurately aligned and functioning, thus eliminating the rings caused by any misalignment or sensitivity errors.

another possible action, although less common, is replacing or repairing faulty detector elements. in some cases, recalibration alone might not suffice, especially if a detector element is damaged or inherently flawed. replacing the faulty elements ensures that all components contribute equally to the image formation, thereby restoring image quality.

adding extra detectors or modifying the existing array of detectors is another approach, though more complex and less frequently employed than simple recalibration. this method might be considered in situations where the existing detector configuration is insufficient to cover the needed range or fails to provide the resolution required for accurate imaging.

lastly, the technologist might check and adjust the software algorithms that process the signals from the detectors. sometimes, the issue might not be purely hardware-related but could also involve the software that interprets the detector outputs. ensuring that these algorithms are correctly handling the data can also help in reducing or eliminating ring artifacts.

overall, while recalibration of the machine’s detector is the most straightforward and commonly used method to correct ring artifacts, understanding the full range of solutions helps technologists effectively manage and maintain the quality of imaging in varied scenarios.

A patient who has had a CT scan procedure with barium sulfate contrast should be instructed to do which of the following after the procedure?

Correct Answer:
drink plenty of fluids


a patient who has undergone a ct scan with barium sulfate contrast should be instructed to drink plenty of fluids after the procedure. the reason behind this advice is primarily linked to the properties of barium sulfate and how it interacts with the body during diagnostic procedures.

barium sulfate is a radiopaque contrast agent used during certain radiological examinations to enhance the visibility of internal structures in imaging. when administered, it coats the lining of the gastrointestinal tract, including areas such as the stomach, intestines, or in some cases, the esophagus. this coating improves the contrast in images, making it easier to diagnose issues like abnormalities or blockages.

however, barium sulfate is not absorbed by the body, which means it must be completely expelled after the procedure. remaining barium can lead to complications such as constipation or impaction. moreover, the process of preparing for a ct scan with barium sulfate often involves fasting and taking laxatives, which can lead to dehydration even before the contrast is administered.

therefore, drinking plenty of fluids after the procedure is crucial. hydration helps in multiple ways: 1. **facilitates the elimination of barium**: adequate fluid intake helps to keep the barium moving through the gastrointestinal system and supports regular bowel movements, which assists in the elimination of the contrast material. 2. **prevents dehydration**: replenishing fluids post-procedure helps to counteract the effects of fasting and the use of laxatives, reducing the risk of dehydration. 3. **enhances overall recovery**: proper hydration contributes to overall bodily functions, which can help the patient recover more comfortably and quickly from the procedure.

in summary, advising patients to drink plenty of fluids after a ct scan involving barium sulfate contrast is essential for safely expelling the contrast material from the body and for preventing potential dehydration and related complications. this step is a standard post-procedure recommendation aimed at ensuring patient safety and comfort.
