This reminds me of the lift scene in the blues brothers where, in between action scenes, they are traveling quietly in a lift listening to muzak. Nothing happening right now.

Let's hope the Optiscan happy ending does not involve our heroes going to jail.

Anyway. Here's something recent to help the die hard true believers to while away the time. (Apologies if its been shared before)

Neurosurgical confocal endomicroscopy: A review of contrast agents, confocal systems, and future imaging modalities.

CONCLUSION

Currently, the frozen section provides intraoperative histopathological analysis of brain tumors. Though useful, this process is time consuming and requires the cutting, freezing, and staining of several biopsies. Frozen section sample preparation frequently damages tissue, alters cellular architecture, and introduces tissue artifacts, all of which hinder a proper diagnosis.[110,113] Application of exogenous fluorophores approved for neurosurgery and miniaturization of confocal microscopy may overcome the limitations of traditional intraoperative histopathology. Future operating rooms may see the routine use of fluorescence confocal endomicroscopes and clinically approved contrast agents, as well as the development of training programs to educate pathologists and surgeons to effectively apply this technology. The translation of this technology for neurosurgical use could improve patient care by providing the neurosurgeon with real-time histopathological information from more regions of interest than are possible with frozen section analysis
