TIRADS, modified TIRADS-Classification or ultrasound based classification of thyroid lesions

Purpose: A TIRADS-System to categorize thyroid nodules was introduced by Horvath et al. 2009 and modified by Kwak et al 2011. This classification is based on the concepts of the BIRADS-Classification. There are some discrepances between Horvath et al. and Kwak et al. in the catalogation of the thyroid lesions. Hovarth et al. described some ultrasound (US) patterns which seem to be not applicable to all thyroid nodules. Kwak et al. do not employ the vascularization of the lesion. These TIRADS-Systems and a modified TIRADS or Ultrasound Based Classification of Thyroid Lesions (UBCTL) are presented Material and met…
