ARRT Registered Radiologist Assistant Sample Test

1 of 5

A patient has presented for a chest radiograph. The female has long hair that is braided on each side. At the center of the braids, she has a hair clip. The patient’s hair clip may impact the chest radiograph by:





Correct Answer:
producing a shadow on the radiograph


the correct answer to the question regarding the potential impact of a hair clip on a chest radiograph is that it may produce a shadow on the radiograph. this is due to the properties of the materials typically used in hair clips, such as metals, which are radiopaque. radiopaque materials do not allow x-rays to pass through them and thus appear as a distinct shadow on the radiographic image.

when preparing a patient for a chest radiograph, it is essential to ensure that there are no extraneous objects in the area being imaged that could interfere with the clarity of the resulting radiograph. this includes removing all metallic or dense objects that could obscure the underlying anatomical structures. items such as jewelry, buttons, hooks, and specifically, hair clips, can create radiopaque artifacts. these artifacts appear as shadows and can obscure important details or mimic pathological findings, which might lead to misinterpretation or misdiagnosis.

in the case of the patient with braided hair secured by a hair clip, the clip could potentially obscure crucial areas of the chest, depending on its position. if the clip is located high enough on the head, it might not interfere. however, if the clip is positioned lower, near the level of the cervical spine or upper thoracic vertebrae, it could project over these regions on the radiograph. this would result in a shadow that might be mistaken for an abnormality or could obscure an existing condition.

therefore, the standard protocol in radiography is to ask patients to remove all potential sources of radiopaque artifacts from the region of interest. this ensures the highest quality diagnostic image, reducing the risk of diagnostic errors and the need for repeat exposures. clear communication about the preparation for the procedure is crucial in achieving optimal results and avoiding any complications or misinterpretations arising from preventable shadows on radiographs.

in conclusion, the presence of a hair clip in a patient undergoing a chest radiograph can produce a shadow on the image, potentially leading to diagnostic challenges. proper preparation and patient instructions are vital to ensure that such artifacts do not compromise the quality and reliability of the radiographic examination.

Great practice for taking the MRI registry..the test gave me a baseline on the knowledge I have and the knowledge I need to study more on before taking the exam. It helped with the verbiage used for the questions.
