Abstract


Since radio iodine(I131)was introduced in the clinic of study of thyroid disorders, diagnostic measures such as the uptake studies, PBI 131 conversion ratio, urinary excretion rate etc. and the treatment of the hyperthyroidism with radio iodine, have been satisfactorily performed.
Allen et al developed script graphy, which enables us to show the shape and size of the gland and to determine intra glandular radioactivity. In this paper sow, new results of thyroid scanning are evaluated. 1. The incidence of goiter in the outpatient clinic.
277 patients with various complaints had their thyroid glands carefully examined. In 39.7% (11 0 patients) the thyroid was palpated. In 14% (39 patients) of these it was just palpable and in 25. 7%(71 patients)the thyroid was found to be more than 2 cm in length and thought to be a goiter. However only in 7.6 % (21 patients) a actually larger than normal thyroid gland was recognized by script graphy.
2. The size of the thyroid gland as estimated by palpation is quite different from its actual size. The estimation of the size of a gland which is felt to be more than 4 cm in length, however, is much closer to its actual size as proved by
script graphy.
3. The normal size of the thyroid gland in the Korean population.
The normal size of the thyroid gland estimated by script igraphy is as follows: right lobe: 4.7±0.62 cm in length and 2.44±0.28 cm in width; left lobe : 4. 3+0. 81 cm in length and 2.23±0.23 cm in Width. The right lobe is situated a little higher than the left. The area of both lobes measured by a planimeter is 16. 5+2.17 cm2.The average weight calculated by Doering and Kramer´s formula is 22.0±4.50 Gm. A thyroid gland measuring more than 22 cm2 or weighing more than 35 Gm is considered to
be enlarged.
4. Determination of the weight of the thyroid. Two methods of determining the weight of the thyroid gland as described by Allen et al and Doering et al were tried and evaluated.
5. There are cases presenting both toxic and nontoxic goiter simultaneously, which could be recognized only by scintigraphy.
6. Classification of cold nodule.
The cold nodules of the thyroid gland proved by scintigraphy could be roughly differentiated in vivo according to their consistency; from the softer thyroglossal duct cyst, colloid goiter, colloid adenoma, cold adenoma to carcinoma.
