Ultrasonic grey scale visualization of the thyroid gland

Ultrasonic examination of the thyroid provides an accurate method of differentiating between solid and cystic lesions. With grey scale echography contents of many solid lesions give rise to a characteristic echo pattern which may eventually allow the ultrasonic classification of these lesions. This preliminary study of 40 patients presents the echograms associated with some of the more common pathological conditions of the thyroid gland.
