Multiplexed imaging in oncology

In oncology, technologies for clinical molecular imaging are used to diagnose patients, establish the efficacy of treatments and monitor the recurrence of disease. Multiplexed methods increase the number of disease-specific biomarkers that can be detected simultaneously, such as the overexpression of oncogenic proteins, aberrant metabolite uptake and anomalous blood perfusion. The quantitative localization of each biomarker could considerably increase the specificity and the accuracy of technologies for clinical molecular imaging to facilitate granular diagnoses, patient stratification and earlier assessments of the responses to administered therapeutics. In this Review, we discuss established techniques for multiplexed imaging and the most promising emerging multiplexing technologies applied to the imaging of isolated tissues and cells and to non-invasive whole-body imaging. We also highlight advances in radiology that have been made possible by multiplexed imaging. This Review discusses established and emerging techniques for the multiplexed imaging of isolated tissues and cells and for non-invasive whole-body imaging.

Automated summary

In oncology, clinical molecular imaging technologies play an important role in diagnosing patients, assessing treatment efficacy, and monitoring disease recurrence. Multiplexed methods that detect multiple disease-specific biomarkers simultaneously can improve the accuracy and specificity of these technologies. This review discusses established and emerging multiplexed imaging techniques and highlights the advances in radiology made possible by multiplexed imaging.
