Definition / general
  • Procedure assistance is determined by:
    • Preference and experience of pathologist performing the procedure
    • Complexity of USFNA procedure and setting (hospital inpatient versus outpatient)
    • Availability of personnel to assist (e.g. private practice versus academic setting)
    • FNA volume and resources available for hiring or training the assistant
  • Possible assistants include ultrasonographer, nurse, cytotechnologist, pathology resident or fellow
  • Highly trained and credentialed professional who performs ultrasound (US) procedures and obtains US images
  • Specially credentialed in US in one or more organ systems including abdomen, breast, ob/gyn, small parts (e.g. thyroid), vascular
  • Excellent resource for pathologist, as they have in depth understanding of US scanning, US physics, US equipment, image guided procedures, normal sonographic anatomy, US images obtained
  • Cost may be prohibitive (salary may be > $60,000 USD depending on experience)

  • Ultrasonographer's duties may include:
    • Obtain previous imaging studies and compare to current study
    • Take patient history, explain procedure, provide patient support and care
