Summary
Minimally invasive interventional oncology therapies consist of various therapeutic catheter-based (such as transcatheter arterial chemoembolization) and percutaneous ablative approaches (such as radiofrequency ablation) using imaging for guidance to treat solid malignancies, and have recently emerged as a major therapeutic alternative against cancer. Monitoring tumour response to these therapies is currently performed by measuring changes in tumour size with contrast-enhanced computed tomography (CT) or magnetic resonance (MR) imaging. However, morphological tumour changes occur relatively late in the course of therapy, while functional changes can occur prior to tumour size changes. Since minimally invasive therapies cause tumour cell membrane destruction and/or obliteration of tumour micro vessels, with subsequent alterations in the microscopic movement of water molecules, DW-MRI seems to be a potential non-invasive tool for measuring early functional tumour response to such therapies.
