Abstract

Bone metastases are common, cause significant morbidity and impact on healthcare resources. While radiographs, computed tomography (CT), magnetic resonance imaging (MRI) and bone scintigraphy have frequently been used for staging the skeleton, it is recognized that these methods are insensitive and non-specific for monitoring treatment response in a clinically relevant time frame.
We summarize several recent reports on new functional and hybrid imaging methods including single photon emission CT / CT, positron emission tomography / CT and whole-body MRI with diffusion-weighted imaging.
These modalities generally show improvements in diagnostic accuracy for staging and response assessment over standard imaging methods, with the ability to quantify biological processes related to the bone microenvironment as well as tumor cells.
As some of these methods are now being adopted into routine clinical practice and clinical trials, further evaluation with comparative studies are still required to guide optimal and cost effective clinical management of patients with skeletal metastases.
