How medical imaging can accelerate drug development
It can take 15 years to get a drug candidate from the lab to approval. Could medical imaging speed up that process? Olga Kubassova, PhD, of Image Analysis Group explains how imaging modalities such as MRI, CT, and PET are helping to track biomarkers in clinical studies, potentially bringing lifesaving therapies to patients more quickly.
