Conventional methods for intraoperative histopathologic diagnosis are labour- and
time-intensive, and may delay decision-making during brain-tumour surgery.
Stimulated Raman scattering (SRS) microscopy, a label-free optical process, has
been shown to rapidly detect brain-tumour infiltration in fresh, unprocessed
human tissues. Here, we demonstrate the first application of SRS microscopy in
the operating room by using a portable fibre-laser-based microscope and
unprocessed specimens from 101 neurosurgical patients. We also introduce an
image-processing method - stimulated Raman histology (SRH) - which leverages SRS
images to create virtual haematoxylin-and-eosin-stained slides, revealing
essential diagnostic features. In a simulation of intraoperative pathologic
consultation in 30 patients, we found a remarkable concordance of SRH and
conventional histology for predicting diagnosis (Cohen's kappa, ? > 0.89), with
accuracy exceeding 92%. We also built and validated a multilayer perceptron based
on quantified SRH image attributes that predicts brain-tumour subtype with 90%
accuracy. Our findings provide insight into how SRH can now be used to improve
the surgical care of brain tumour patients.
