American Registry of Radiologic Technologists (ARRT) Practice Exam

Which radiographic procedure requires the use of sterile gloves when handling items on the tray?

1. Myelogram

2. CT Scan

3. Ultrasound

4. X-ray

The correct answer is: Myelogram

The myelogram procedure involves the introduction of contrast material into the spinal canal to enhance imaging of the spinal cord and nerve roots. This process typically requires a sterile environment due to the invasive nature of the procedure, where the potential for infection must be carefully managed. Sterile gloves are essential for maintaining the sterility of the equipment and preventing contamination when handling the tray and items associated with the myelographic procedure. In contrast, the other procedures—CT scans, ultrasound, and X-rays—are not invasive in the same manner and do not require the same level of sterility. Although cleanliness is important in all medical imaging procedures, the use of sterile gloves is specifically critical in myelography due to the direct access to the central nervous system and the associated risks if sterile techniques are not adhered to.
