No conflict of interest to disclose.
1. Outline how Cytotechnologist’s role has evolved to include
imaging and procedure assistance in the experience of an
ultrasound-guided FNA (USFNA) service in an academic
Pathology Department setting.
2. Identify the steps necessary for a Cytotechnologist to
become an active part of a USFNA service, making use of
a suggested timeline and available learning resources.
3. Recognize the advantages and challenges of active
Cytotechnologist’s participation in USFNA, from a
Cytotechnologist’s and from a Cytopathologist’s point of
view.
Learning Objectives:

Evolution of FNA Service at VCUHS
Dr. Frable – instrumental in bringing FNA cytology to the US
Residents perform the
FNAs at bedside or in the clinics as
requested
Fellows attend deep FNA
procedures in CT,
ultrasound, endoscopy,
bronchoscopy
Cytotech accompanies
a fellow to deep FNAs or
2 cytotechs attend deep FNA if fellow is unavailable
Pathologists perform US-guided FNAs
with assistance
from resident or cytotech
8
Pathologist-performed USFNA at VCUHS
US-guided fine needle aspiration of superficial lesions is now performed
by pathologists (since 2011)
US-guided fine needle aspiration of breast and deeper lesions are still
performed by radiologists
9
When we started:
One pathologist
One ultrasonographer
One secretary
One CT as a backup for the ultrasonographer
Most FNAs were done in clinics using portable equipment.
(There was no permanent FNA area in pathology.)
10
Currently:
Four pathologists
Secretarial support
Multiple cytotechnologists and residents have been trained to assist
Dedicated space for the service:
• Waiting area
• Receptionist area
• 2 exam rooms
• Mini-lab for staining and microscopic examination
(Still bring portable equipment to clinics on request).

Role of the Cytotechnologist in USFNA
1. Maintaining the cytodiagnosis center
• Inventorying supplies and restocking as needed
• Weekly stain maintenance
• Archiving of images
17
Role of the Cytotechnologist in USFNA
2. Setting up for the procedure
• Entering patient information into the ultrasound machine
• Making sure settings on the device are appropriate
• Getting out the supplies that are needed
• Consenting and timeout procedure
18
Some of the supplies that need to be within reach for each procedure:
19

3. Assisting with the procedure:
• Reassuring the patient
• Handing supplies to the pathologist
• Pulling suction or holding probe during the aspiration
• Labeling the screen with appropriate notations
• Adjusting image parameters, as needed
• Saving appropriate images or cine loops during the procedure
• Holding pressure after the aspiration
• Helping to make smears and staining slides

3. After the procedure:
• Talking with the patient (post-procedure survey)
• Annotating images, measuring lesion
• Disinfecting the equipment and other surfaces
• Cleaning up and preparing the room for next procedure
• Taking material to the main lab for accessioning and processing
• Screening case and reporting results including the procedure notes

4. Other functions as needed:
• Assessing adequacy
• Patient scheduling
• Reception and patient registration
• Scanning patient documents into electronic chart
27
Training Time:• First cytotech was in training for about 6 months and served as the
backup for the US tech (procedures were few and far between at first)
• Timeline was shorter for second CT since there were more procedures
more often
• Began training second CT in Summer 2013, when the US tech would be
leaving
• Spent time one on one with the US technologist learning the equipment
• Watched training videos and read training materials
• Observed procedures for about a month with minimal hands-on
involvement
• Began assisting on procedures for about one month with the guidance of
the previously trained CT
• Since then I have been involved in training 5 other CTs which is very
helpful in reinforcing what you know
• Learning is ongoing though!!
28
• Introduce the equipment and supplies and explain the procedure while
there is not a patient to focus on
• Make training videos and printed materials available for self-study
• Allow trainee to observe several actual procedures without expecting
them to contribute
• Ease the trainee into assisting with the procedure by allowing them to
do things they are comfortable with, such as holding pressure after each
pass or staining slides
• After observing several procedures let the trainee set up supplies and
operate the ultrasound machine with an experienced tech near by for
guidance
• Each trainee will be different and will have a different comfort level. It’s
important to make sure they get as much practice and guidance as they
need to feel comfortable and proficient
• The more comfortable the cytotech is with assisting on procedures the
more comfortable and less anxious the patient will be!
Tips for training a cytotech to assist with USFNA:
29
Training Cytotechs to assist with USFNA
Involves learning in 4 areas:
• Ultrasound Equipment
• Ultrasound Terminology
• Ultrasound Anatomy
• Assisting with Procedures
30
Ultrasound Equipment: what you need to know:
Names and location of various parts and controls
The function of controls and how to use them.
For example:
• Gain
• Depth
• Doppler
• Save image and save cine features

LightToo Much Gain
34
Adequate Gain Setting Look for:
- vascular lumens to be black without any white or grey internal echoes
- Other tissues, like skeletal muscle should have good contrast tones
Gain
35
allows stepwise control of the amplification of the returning echoes from different depths

Ultrasound Terminology
38
Echogenicity – the extent to which sound waves are reflected
39
Describing Echogenicity
Isoechoic – the same echogenicity as reference tissue
Hyperechoic – more echogenic (brighter) than reference tissue
Hypoechoic – less echogenic (darker) than reference tissue
Anechoic- Neither having nor producing echoes (black)
reference
Patterns of Echogenicity
40
Homogeneous - uniform in composition
Heterogeneous - lacks uniformity
