In Vivo Microscopy Topic Center

Pathologists are key players in the development, validation, and clinical implementation of new microscopic imaging technologies. At the forefront is In Vivo Microscopy, where microscopic images are obtained in vivo, in real- time, during clinical procedures.

In Vivo Microscopy in Detail

In Vivo Microscopy (IVM) is an exciting field where microscopic images are obtained in vivo, in real-time, during clinical procedures. IVM imaging technologies use light and rapidly produce 2D or 3D (tomographic) microscopic images. These images may be obtained using instrumentation compatible with existing standard of care clinical instruments (e.g., that can be inserted into endoscope accessory ports) or as standalone imaging tools. IVM is in clinical use in Gastroenterology, Ophthalmology, Cardiology, Dermatology, and in other clinical disciplines, including Pulmonary Medicine, Urology, Breast, and Neurosurgery.

Why Pathologists are Central to IVM

Pathologists are the experts in diagnosing disease through the interpretation of diagnostic microscopic images. With the evolution of IVM technology, their expertise to properly interpret new types of microscopic images establishes a role for pathologists as interventional microscopists.

Benefits of In Vivo Microscopy

  • Guide biopsy site acquisition in real time to obtain targeted and diagnostically significant biopsies, as in pulmonary nodules or breast cancer
  • Perform comprehensive screening for occult microscopic disease, as in capsule screening for Barrett Esophagus
  • Obtain microscopic diagnoses when tissues cannot be easily or safely excised, as in coronary arteries, retinal screening or pulmonary fibrosis
  • Guide and assess the efficacy of therapy, such as in chemotherapy, laser ablation, guided surgical ablation, focused ultrasound, cryotherapy, radiofrequency, and brachytherapy

Ex Vivo Microscopy of IVM in Detail

Ex Vivo Microscopy (EVM) is the use of IVM technologies by pathologists in the ex vivo setting, without damage or destruction to the tissue. EVM imaging systems are small and portable, and can be used in virtually every pathology setting: the surgical suite, the procedure room, the grossing room, the laboratory, and the biobank. EVM creates digital images that can be viewed and interpreted remotely so the pathologist does not need to be physically present for EVM to be useful. Digital EVM images can be sent electronically to remote pathologists for consultation, and also used as digital documentation of biobank and other research tissues.

Benefits of Ex Vivo Microscopy

  • Evaluate small tissue biopsies for adequacy, as in breast, lymph nodes, and lung cancer biopsies.
  • Triage biopsy and other tissues for molecular and genomic studies, as in lung cancer
  • Guide the selection of tissue for frozen and permanent sections for diagnostic material
  • Guide tissue collection for Biobanking and other research purposes
