We retrospectively investigated all of the patients who were evaluated for their thyroid function and underwent thoracic computed tomography (CT) in the emergency department of Juntendo University Hospital between April 2011 and April 2013. The subjects were divided into two groups: the SH group included subjects who received a diagnosis of subclinical hypothyroidism (SH), while the Control group included subjects who had a normal thyroid function. The definition of SH was a normal-range free T4 level and thyroid-stimulating hormone (TSH) over 5 mIU/L. The patients’ age, sex, underlying diseases and values of TSH, free T3, free T4 as well as the average CT value of both thyroid glands and the presence of contrast between the thyroid gland and sternocleidomastoideus muscle were compared between the two groups.
