Abstract

Abstract

Background: Early detection of many thyroid disorders is essential in the management. Ultrasound elastography is beneficial in the assessment of diffuse thyroid diseases.

Aim of study: To assess the role of ultrasound strain elastography in the diagnosis of diffuse non nodular thyroid disease in comparison to healthy controls and in the characterization and differentiation of the types of diffuse thyroid diseases.

Patients and methods: It is a prospective analytic study performed in the Radiology Department of Oncology Teaching Hospital/Medical city Complex in Baghdad during the period from 1^st of December 2019 to 30^th of June, 2020 on convenient sample of 25 patients with diffuse thyroid disease, in addition to a sample of 25 healthy control persons. The diagnosis of diffuse thyroid diseases was made by combination of clinical symptoms, laboratory investigations and thyroid ultrasound.

Results: The mean elastography strain ratio (1.36) of patients with diffuse thyroid disease was significantly higher than (0.82) mean of elastography strain ratio for healthy control persons (p<0.001). The acceptable cutoff elastography strain ratio in the diagnosis of diffuse thyroid disease was 0.89 with validity results (80% sensitivity, 70% specificity and 75% accuracy). The mean elastography strain ratio for patients with Hashimotos thyroiditis was significantly higher than the strain ratio of patients with Graves disease (p=0.002).

Conclusions: The ultrasound elastography is useful in the assessment and characterization of diffuse thyroid disease. The ultrasound elastography strain ratio value is helpful in differentiation between different diffuse thyroid diseases especially between Hashimotos thyroiditis and Graves's disease
