Assessment of response following treatment for malignant disease

Monitoring tumour response to therapy is an increasingly important aspect of oncological radiology. Cancer is increasing in incidence in the UK and recent advances in treatment have resulted in many more patients surviving with treated disease. Concurrent advances in imaging techniques over the past two decades permit us to obtain detailed morphological and functional information from treated tumours. This article reviews clinical strategies for imaging patients following treatment for cancer with particular reference to techniques which are currently under continuing scientific evaluation.
