Summary

Thyroid nodules are common in clinical practice. Head and neck ultrasound is recommended as a routine examination for all patients with thyroid lesions. The Thyroid Imaging Reporting And Documentation System (TIRADS) criteria helps to estimate the risk of malignancy based on ultrasound patterns and nodule sizes guiding the performance of fine-needle-aspiration (FNA). Approximately 20% of FNA results cannot be specified whether being benign or malig-nant tissue. A definitive diagnosis can only be made from histopathology after diagnostic (hemi)thyroidectomy. However, (hemi)thyroidectomy has disadvantages as it leads to over-treatment and has a risk of postoperative morbidity (e.g. hypothyroidism and laryngeal nerve injury). Furthermore, (hemi)thyroidectomy is known to be associated with poor quality of life. Clearly, there is an unmet need for additional diagnostic tools in order to identify malignant thyroid nodules and thereby support the decision making for treatment of the thyroid. Multispectral optoacoustic tomography (MSOT) is an innovative, non-invasive imaging method currently available in the UMCG that enables visualization of endogenous chromophores and exogenous contrast agents using the generation of ultrasound waves due to light absorption by using high frequency pulsed laser light. Recently, this system has been used by other groups for non-invasive determination of thyroid nodules. Results show that multispectral optoacoustic imaging of thyroid nodules may distinguish benign from malignant nodules. However, most certainly, a larger cohort is necessary to confirm this finding.
