What are the limitations of an Ultrasound exam?

Posted on August 26, 2015

It may be difficult for a sonographer or doctor to obtain the desired pictures if you have a short or thick neck. Also, if there are multiple nodules or cysts, it can be difficult for the doctor to see each one individually. An ultrasound examination of the thyroid cannot determine the exact cause of a nodule; however, there are characteristics of the image that can help the doctor determine if there is a high chance of cancer (malignant) or a low chance of cancer (benign). Your doctor may recommend further tests, such as an ultrasound-guided biopsy or a fine-needle aspiration. Finally, the quality of the ultrasound examination also depends on the examiner’s experience and the type of equipment used.
