Changes in hormonal status, changes in ultasound presentation. Table 4: The effect of normalization of elevated TSH-level - Case 80
Initial examination (TSH 132.4 mIU/L)
3 months later (TSH 0.29 mIU/L)
Another 6 months later (TSH 1.46 mIU/L)
     
Over 6 years of follow up only small differencies can be observed in gray scale pattern, there is significant difference neither in the degree of hypoechogenicity nor in the size of the thyroid. Although the difference in vascularization may be explained by the difference of sonographic equipments (the investigation in 2007 was performed by Sonosite 180 while in 2011 and 2013 by Sonosite Micromaxx), the vascular pattern used not to be as stable as the gray scale pattern in Hashimoto's thyroiditis.
