Mandatory medical device diagnostics.
- Thyroid ultrasonography (ultrasound examination of the thyroid gland) – as a basic examination to determine the size of the thyroid gland and any tissue irregularities, such as nodules
Optional medical device diagnostics – depending on the results of the history, physical examination, laboratory diagnostics and mandatory medical device diagnostics – for differential diagnostic clarification.
- Doppler sonography (ultrasound examination that can dynamically visualize fluid flow (especially blood flow)) – to distinguish amiodarone-induced hyperthyroidism (AIH) type I from type II.
- Thyroid scintigraphy (imaging of the thyroid gland and its function using radioactive substances) – to estimate the activity of the thyroid gland or in suspected cases of
- Thyroid malignancy (thyroid cancer) in the presence of a definable focal finding.
- Thyroid autonomy in the presence of hyperthyroidism [increased accumulating (= hyperfunctional = “warm or hot”) thyroid nodule]
- Unclear chronic lymphocytic thyroiditis (Hashimoto’s thyroiditis) thyroiditis).
- Fine needle biopsy (sonography-guided tissue sampling) – for abnormalities in thyroid scintigraphy or sonography.
- Computed tomography (CT; sectional imaging procedure (X-ray images from different directions with computer-based evaluation)) – for imaging the complete neck region in abnormalities in thyroid scintigraphy or sonography.
- Magnetic resonance imaging (MRI; computer-assisted cross-sectional imaging (using magnetic fields, that is, without X-rays) – for imaging the complete neck region in abnormalities in thyroid scintigraphy or sonography.
