Cancer imaging and new preclinical diagnostics in radiation oncology

Future perspectives in radiation oncology are built on new developments in cancer biology, improved radiation technology and enhanced imaging capabilities, with preclinical developments driving the clinic and vice versa. On the one hand, many existing techniques are more frequently used in radiotherapy for new, interesting purposes, such as the treatment planning or response assessment, whilst different functional and molecular imaging methods with corresponding biomarkers are currently being developed and characterized pre-clinically with the perspective of clinical translation. The aim of this collection of articles is to highlight the current state of the field and features a review article by Cyran and colleagues on Visualization, imaging and new preclinical diagnostics in radiation oncology.

    MRI and CT imaging for preoperative target volume delineation in breast-conserving therapy

    Accurate tumor bed delineation after breast-conserving surgery is important. However, consistency among observers on standard postoperative radiotherapy planning CT is low and volumes can be large due to serom...
