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

Role of the Cytotechnologist in USFNA

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
