Introduction to the Stepwise Development of Imaging Biomarkers,al has changed. Clinical radiologists must now incorporate biological development and preclinical research into a clinical reality. The use of imaging measurements in individual patients improves the main clinical outcomes, such as depicting abnormalities, predicting prognosis, staging diseases, and

Defining the Biological Basis and Clinical Question (Proof of Concept); Looking for the Interrelatiber of reasons. For any newly developed (imaging) biomarker, the underlying pathophysiological mechanism has to be understood, and the corresponding biomarker has to be a valid and reproducible surrogate for this pathophysiological process (proof of concept and proof of mechanism). Hence, the role o

Medical imaging overcomes the three main difficulties that traditional clinical endpoints have, such as (1) their difficulty to be standardized or quantified, (2) the long time required to be manifested, and (3) their high costs, particularly when long-term endpoints, such

Imaging Biomarker Measurements,ct numerous quantitative features from computed tomography (CT), magnetic resonance (MR), and positron emission tomography (PET) images. The conversion of digital medical images into mineable high-dimensional data is called radiomics and is motivated by the concept that biomedical images contain inf

Pearls and Pitfalls in Gold Standards and Biological Correlation, imperfect reference standard, strategies to handle imperfect “gold standards” and how to achieve the best possible validation. These topics are illustrated by reference to three currently used markers: MR elastography as a surrogate marker of liver fibrosis stage, CT colonography detected adenomas
