The Sonographic Features of the Thyroid Gland After Treatment with Radioiodine Therapy in Patients with Graves' Disease

Thyroid Ultrasound: State of the Art Part 1 – Thyroid Ultrasound reporting and Diffuse Thyroid Diseases

“…Tips and tricks Thyroid scintigraphy is often used in cases where the cause of the hyperthyroidism is unclear and to evaluate for thyroid nodules before treatment [35]. Society of Radiologists in Ultrasound [36] recommend that sonographic features of individual nodules in a multinodular gland should be the primary criteria for suggesting biopsy rather than using nodule size.…”

“…Compared to Hashimoto's thyroiditis, the appearance of the thyroid in Graves' disease is less heterogeneous and the contour is lobulated [53]. Features of increased volume, hypervascularity, and heterogeneous reduced echogenicity have been shown in Graves' disease [35].…”

“…The sonographic features of the post-RIT gland included a significantly reduced mean total volume of 4.2 mL, hypovascularity, coarse echotexture, and hyperechogenicity [35]. Currently, thyroid imaging does not play a routine role in the post-treatment follow-up of RIT patients, but thyroid ultrasound would be employed if there was a change in the size (enlargement) or nodularity of a treated gland [35].…”

US-Doppler colorido da glândula tireoide, em pacientes com doença de Graves, antes e após radioiodoterapia (131I): correlação com quadro clínico-laboratorial

“…Tomoco Watanabe, por confiar a mim os exames dos seus pacientes, por acreditar que eu seria capaz de concluir o acompanhamento por esse longo período e principalmente pelos ensinamentos e execução dos exames de Medicina Nuclear. (48) : Padrão 0 -normal: a vascularização está limitada às artérias principais periféricas, enquanto no parênquima não existe vestígio de fluxo ou há raros pontos com traços reduzidos. Padrão I -pouco aumentada: discreto aumento do sinal colorido das artérias tireóideas periféricas e presença de vascularização do parênquima com distribuição desigual e em pontos focais ou, ainda, no interior dos nódulos.…”
