A data-efficient and interpretable deep-learning method for the multi-class classification of whole-slide images that relies only on slide-level labels is applied to the detection of lymph node metastasis and to cancer subtyping.
Advances in microscopy and the application of machine learning to histology will modernize the examination of tissues in the clinical laboratory and in the operating room.

This Perspective reviews imaging technologies for 3D pathology, and the associated computational tools for image processing and interpretation.
Deep learning can be used to virtually stain autofluorescence images of unlabelled tissue sections, generating images that are equivalent to the histologically stained versions.
A slide-free, inexpensive and non-destructive microscopy technique rapidly provides high-resolution histology images that resemble those obtained from conventional haematoxylin-and-eosin-stained specimens.
Whole-tissue biopsy phenotyping of three-dimensional tumours reveals patterns of cancer heterogeneity
A method that identifies patterns of tumour heterogeneity in intact biopsy samples using 3D light-sheet microscopy stratifies patients by tumour stage.
A light-sheet microscope images large surgical and biopsy specimens non-destructively over large fields of view in two and three dimensions, with the same level of detail as traditional slide-based histopathology.
Rapid intraoperative histology of unprocessed surgical specimens via fibre-laser-based stimulated Raman scattering microscopy
By taking advantage of stimulated Raman spectroscopy and fibre-laser technology, virtual histology images can be obtained in real time in the operating room, with diagnostic quality comparable with that achieved via conventional histopathology.
News & Comment
A deep-learning model for cancer detection trained on a large number of scanned pathology slides and associated diagnosis labels enables model development without the need for pixel-level annotations.
Histologically stained slides can be generated from unlabelled autofluorescence images of tissue samples via deep learning.
Optical imaging of fluorescently labelled tissue illuminated by ultraviolet light does not require microscope slides and makes for a rapid alternative to conventional histology.
Light-sheet microscopy reveals 3D tumour heterogeneity in optically cleared paraffin-embedded tumour samples.
A light-sheet microscope offers fast three-dimensional imaging of intact clinical tissue samples over large fields of view.
Stimulated Raman spectroscopy combined with machine learning generates histological images for the rapid diagnosis and classification of brain tumours.
