CT and MRI in Oncology [Paperback]

Imaging techniques are often called upon in oncology in virtue of their essential role in tumor diagnosis, extension work up to various organs and detection of relapse. They are also indispensable in research and in clinical practice, allowing an objective assessment of tumoral regression in patients undergoing treatment. It is currently impossible to establish the management plan of a cancer patient or to obtain follow-up of such a patient under treatment without clinical and imaging confrontation.Imaging techniques are often called upon in oncology in virtue of their essential role in tumor diagnosis, extension work up to various organs and detection of relapse.
