Saunders Company: Philadelphia. Pediatric Sonography. Measurements for the trachea showed a mean value of 19.97 mm (SD 2.37 mm). The normal thyroid measures 5.0cms (length) x 1.1cms (A-P anteroposterior) X 1.4 cms (transverse TRV) and the abnormal thyroid measures 8.5cms (craniocaudad), by 3.9cms (A-P) by 4.8cms (transverse). Clinical findings were consistent with thyroiditis, with biochemical findings suggesting hypothyroidism. Ultrasound is a painless method that uses sound waves to create images of the inside of the body.
