What are the ARRT exams?

You are considering a career in radiologic technology and hear about the ARRT exam requirement. Just what do the ARRT examinations entail?

What is the American Registry of Radiologic Technologists (ARRT) ?

The American Registry of Radiologic Technologists (ARRT) is an organization that grants certification and registration to qualified individuals in medical imaging, interventional procedures, and radiation therapy. ARRT offers 13 credential options via three pathways: primary, post-primary, and physician extender. While the three pathways share the same exam requirements, they vary in education requirements. More specifics on pathways and requirements can be found at www.arrt.org.

Eligible candidates must sit for an ARRT examination that measures knowledge of daily tasks that an entry-level technologist performs. These computer-based tests, administered by Pearson Vue, consist mainly of multiple-choice items. Testing times vary according to discipline and range from 2 ¼ hours up to 7 ½ hours, with most lasting about 4 hours. This total test time includes time for a tutorial and a non-disclosure agreement prior to testing and a survey following test completion. Likewise, the total number of items range from 105 on the bone densitometry exam to 400 for the sonography exam. This total number includes a sampling of pilot items which appear randomly throughout the test and do not count toward scoring. Exam items focus on the major content areas of patient care, image production, procedures, and safety. Specific topics addressed within each major content category can be found at the ARRT website.

You will receive a preliminary score on the computer after completing your exam. Your final score packet will be mailed within 4 weeks. This final score packet will include the official score report and certification and registration results. Scores are scaled and range from 1 – 99 with 75 being the minimum score needed to pass.


ARRT Computed Tomography - FAQ Sample Questions

Which of the following is Not typically included in LFTs (Liver function tests)?





Correct Answer:
egfr


liver function tests (lfts) are a group of blood tests that provide information about the state of a patient's liver. these tests include various parameters that measure the levels of liver enzymes, proteins, and bilirubin in the blood. common components of lfts include alanine aminotransferase (alt), aspartate aminotransferase (ast), alkaline phosphatase (alp), albumin, and total bilirubin. these tests help detect liver damage or disease and monitor the progression or improvement of liver conditions.

alanine aminotransferase (alt) and aspartate aminotransferase (ast) are enzymes that help break down proteins and are primarily found in the liver. when the liver is damaged, alt and ast are released into the bloodstream, and their levels increase. alkaline phosphatase (alp) is another enzyme found in the liver, bones, and other tissues. elevated levels of alp can indicate liver disease or bone disorders. albumin, a protein made by the liver, helps maintain pressure in the bloodstream and transport vitamins, hormones, and drugs throughout the body. low levels of albumin can suggest liver dysfunction. bilirubin, a yellow pigment formed by the breakdown of hemoglobin in red blood cells, is processed by the liver and excreted in bile. high levels of bilirubin may indicate liver problems or other conditions affecting red blood cells.

on the other hand, the estimated glomerular filtration rate (egfr) is not typically included in liver function tests. the egfr is a measure of how well the kidneys are filtering and clearing waste products from the blood. it is calculated based on the creatinine level in the blood, age, body size, and gender. egfr is a crucial test for assessing renal (kidney) function but does not provide information about liver function. therefore, it is not part of the standard liver function tests panel.

in summary, while tests like alt, ast, alp, albumin, and bilirubin are integral components of liver function tests, the egfr is specifically used to evaluate kidney function and is not included in lfts. understanding the distinction between these tests is important for accurate diagnosis and monitoring of liver versus kidney health.

When would partial volume artifacts occur?





Correct Answer:
when a voxel contains two dissimilar materials


partial volume artifacts occur in imaging techniques like mri and ct scans, primarily when a voxel (the smallest distinguishable box-shaped part of a three-dimensional image) contains a mixture of two or more different types of materials or tissues. this situation commonly arises due to the finite resolution of the imaging system, where each voxel represents an average of all the structures within that voxel space.

when a voxel is occupied by a single material, the signal generated is uniform and represents that material accurately. however, if the voxel contains two dissimilar materials, the resulting signal is a blend of the responses from both materials. this blending can lead to inaccuracies in the image, as it might not accurately represent the spatial distribution of the materials. for instance, if a voxel on the boundary of bone and soft tissue includes parts of both, the image may neither accurately reflect the bone density nor the soft tissue structure, leading to a distorted or misleading representation.

these artifacts are particularly problematic in areas where different tissue types interface closely, such as the junctions between soft tissue and bone or the boundaries of organs surrounded by fatty tissue. the partial volume effect can lead to underestimation or overestimation of the extent of a lesion or abnormality, and can affect both the diagnosis and the therapeutic planning processes. for example, in neurological imaging, partial volume effects can complicate the assessment of brain lesions or the cortical bone in orthopedic imaging.

in summary, partial volume artifacts occur due to the averaging of different materials within a voxel, leading to potential misrepresentation in the resulting image. this phenomenon is an inherent limitation of current imaging technologies, driven by voxel size and the spatial resolution of the imaging system. efforts to minimize these artifacts include the use of higher resolution imaging, sophisticated software algorithms to correct for partial volume effects, and careful interpretation by experienced radiologists.
