Wavelet-based algorithm to the evaluation of contrasted hepatocellular carcinomain CT-images after transarterial chemoembolization

摘要

BackgroundHepatocellular carcinoma is a primary tumor of the liver and involves different treatment modalities according to the tumor stage. After local therapies, the tumor evaluation is based on the mRECIST criteria, which involves the measurement of the maximum diameter of the viable lesion. This paper describes a computed methodology to measure through the contrasted area of the lesions the maximum diameter of the tumor by a computational algorithm.
