Assessment of diagnostic potential of dye‐enhanced multimodal confocal imaging. Abbreviations: NP = neuropathology; NPV = negative predictive value; PPV = positive predictive value

Comparisons	Sensitivity (%)	Specificity (%)	PPV (%)	NPV (%)
Normal vs. abnormal brain tissue	95	100	100	98
Glial vs. nonglial tumors	83	90	91	80
Grade and type of the tumor: all pathologists	63	46	76	32
NP trained*	88	100	100	86
*P‐value	0.0264	<0.0001	<0.0001	0.0016

Multimodal confocal imaging is compared with haematoxylin and eosin (H&E) diagnosis as a standard of care.

NP is significantly better in grading and subclassifying tumors.
