Clinical applications for dual energy CT versus dynamic contrast enhanced CT in oncology.

Both Dual Energy CT (DECT) and Volume Perfusion CT (VPCT) have gained interest in recent years with several studies providing evidence of benefits for both in a variety of oncological settings. These technologies open a new spectrum of diagnostic opportunities aiming at an improved detection and characterization of suspected tumor lesions, early evaluation of therapy response and generally more accurate treatment monitoring. Here, we review and discuss current advances, beneficial aspects and potential shortcomings of both imaging modalities with regard to their clinical use in oncology.
