In Vivo Microscopy (IVM)
Definition of IVM:
• A new field where microscopic images are
obtained in real time from living patients
- Technologies currently use light
- Images may be rapidly acquired in 2D and 3D
- Images may be obtained using instrumentation
that can be inserted into endoscope accessory
ports or as standalone imaging tools
![Page 7: Welcome to CAP’s “IVM” Webinar Series sponsored by the · esophagus stomach 500 µm 1 cm 500 µm Normal Volunteer • Examples: OCT images of coronary arteries in vivo In-stent](https://reader030.fdocuments.us/reader030/viewer/2022040608/5ec39facd3a0e2778b4b158b/html5/thumbnails/7.jpg)
Goals of IVM
• Guide the acquisition of targeted and more
meaningful biopsies
• Screen entire organs for occult microscopic disease
• Obtain microscopic diagnoses when tissues cannot
be easily or safely excised
• Assess the efficacy of therapy
![Page 8: Welcome to CAP’s “IVM” Webinar Series sponsored by the · esophagus stomach 500 µm 1 cm 500 µm Normal Volunteer • Examples: OCT images of coronary arteries in vivo In-stent](https://reader030.fdocuments.us/reader030/viewer/2022040608/5ec39facd3a0e2778b4b158b/html5/thumbnails/8.jpg)
Technologies
Commercially available and FDA-approved
• Optical coherence tomography (OCT)
• Confocal microscopy
- Confocal laser endomicroscopy (CLE)
• Volume laser endomicroscopy (VLE)
Many other technologies used in research
Material costs (estimates)
• Equipment: ~$50K-$250K
• Endoluminal probes: ~$100-$1000/use
![Page 9: Welcome to CAP’s “IVM” Webinar Series sponsored by the · esophagus stomach 500 µm 1 cm 500 µm Normal Volunteer • Examples: OCT images of coronary arteries in vivo In-stent](https://reader030.fdocuments.us/reader030/viewer/2022040608/5ec39facd3a0e2778b4b158b/html5/thumbnails/9.jpg)
Optical Coherence Tomography (OCT)
• Enables visualization of microscopic tissue
architectural morphology
• Analogous to ultrasound, but uses light to achieve
higher resolution
• Provides cross-sectional and 3D images
• 10 µm resolution in depth
• 30-40 µm resolution in plane parallel to surface of
tissue
• Contrast arises from scattering within tissue

IVM Application Areas and Timeline
![Page 20: Welcome to CAP’s “IVM” Webinar Series sponsored by the · esophagus stomach 500 µm 1 cm 500 µm Normal Volunteer • Examples: OCT images of coronary arteries in vivo In-stent](https://reader030.fdocuments.us/reader030/viewer/2022040608/5ec39facd3a0e2778b4b158b/html5/thumbnails/20.jpg)
Some Potential Case Use
Scenarios
• In vivo
- Real-time diagnosis
• in the endoscopy or interventional suite (pathologist present during the procedure)
• at remote site (images transmitted to a pathologist viewing workstation)
- Regular signout
• pathologist views images off-line after procedure is performed
• Ex vivo • Adequacy of needle biopsy
• Pathologist uses equipment and renders diagnosis in real time as intraoperative consult
• Pathologist uses equipment to guide tissue section sampling in grossing room
![Page 21: Welcome to CAP’s “IVM” Webinar Series sponsored by the · esophagus stomach 500 µm 1 cm 500 µm Normal Volunteer • Examples: OCT images of coronary arteries in vivo In-stent](https://reader030.fdocuments.us/reader030/viewer/2022040608/5ec39facd3a0e2778b4b158b/html5/thumbnails/21.jpg)

• Multidisciplinary collaborations between
pathologists and medical subspecialists
- Contact local pathologists who are experts in
reading microscopic images and can help set up
and integrate these technologies into patient
care work flow

• This guide was created to assist pathologists who
are considering providing or developing in vivo
microscopy skills and services within the next 24
months.
