PET imaging for cancer immunotherapy: the Immuno-PET

Checkpoint immunotherapy has revolutionised medicine and is now a cornerstone treatment for the majority of cancer types. Despite intense efforts to identify biomarkers of response, predominantly focused on tumour biopsies taken prior to treatment, none are sufficiently robust to direct treatment, in part due to intertumoural heterogeneity. The Immuno-PET may overcome this, via a total-body, noninvasive, imaging procedure to explore the presence proposed biomarkers across the whole patient, in vivo.
