Figure 2From: Proposed algorithm for management of patients with thyroid nodules/focal lesions, based on ultrasound (US) and fine-needle aspiration biopsy (FNAB); our own experience Low risk thyroid nodule/focal lesion US pattern. A. Ultrasound picture of the thyroid lesion (B-mode). The scoring system â 1.5 points (low risk US pattern 0â<â4 points); E â hypoechogenicity; C2 â solid composition; FNAB cytology in this case - category II TBSRTC; management - observation and repeat FNAB examination after 18Â months. B. Ultrasound picture of the thyroid lesion (Power Doppler), peripheral blood flows.Back to article page
