Final answer:
Acceptable radiographs for the PTCE include MRI scans, mammograms, and X-rays that must be of diagnostic quality and properly labeled. The images should be recent and accompanied by a written explanation of post-exposure treatments. Radiation doses are minimized through shielding, appropriate distance, and limited exposure time.
Step-by-step explanation:
To become a certified radiography technician, one must understand the requirements for the Pharmacy Technician Certification Exam (PTCE) as it pertains to radiographs. Acceptable radiographs for the PTCE include various types like MRI scans, mammograms, and X-rays. These imaging techniques can depict different body structures, such as soft tissues, organs, or bones, by using radiowaves or fluorescently labeled isotopes. Radiology departments that adhere to PTCE standards require diagnostic radiographs to meet certain criteria for clinical usefulness and patient safety.
Radiographs must be of a diagnostic quality, clearly showing the area of interest, and must be recent enough to reflect the current condition of the patient. The age of acceptable radiographs varies depending on the body part and pathology in question but should generally be no more than a few years old, unless treating a chronic condition where historical images provide valuable comparison. Labeling of the radiographs should include the patient’s name, the date of the study, and specific orientation markers. Furthermore, clinicians must provide a written explanation on the Progress Form for any post-radiographic exposure restorative treatment, explaining how the imaging has informed the treatment plan.
Technicians are educated on the necessity to balance the quality of an image with the radiation dose administered to the patient. Protective measures such as shielding, appropriate distance, and limiting exposure time are essential to reduce the dose. The increasing use of faster films and digital imaging technologies in the medical field helps to achieve high-quality images with lower doses of radiation.
