Purpose
The estimation of therapy efficacy plays a central role in the follow-up process of every patient.
The assessment and alteration of therapy is especially emphasised in oncology area.
This complex decision process requires objectiveness which was achieved by introduction of more quantitative method of interpretation.
Thus,
in order to standardise clinical evaluation,
Response Evaluation Criteria in Solid Tumours (RECIST) was established in 2000 and revised (RECIST 1.1) in 2009 (1).
Therefore,
the measurement and the objective estimation of change in tumour size were introduced in clinical trials.
However,
RECIST and RECIST-like guidelines have also been successfully applied in daily radiologist’s practice patterns (2).
The current study was designed in order to demonstrate that measurements of metastatic liver lesions performed in accordance with RECIST 1.1 criteria require minimal training and are easily understandable for experienced radiologists as well as radiology residents.
