thyroid and mri w/contrast

[juscallmede]

Hi. In the last 3 years life has become difficult. I had 2 mri's done within 2 weeks of each other. Up until that time I had borderline hypothyroidism. Now I have hoshimoto's/hypothyroidism. Is it possible that those tests contributed to more damage of my thyroid? I am still having trouble with my back and the doctors are wanting another mri but I am very very hesitant due to the iodine and the damage it may have on my thyroid. Is there reason to be concerned over this?

The last sono was on 1/24/2011. I am hoarse all of the time now, throat sore, problem swollowing and can feel the buldge.  I have spasms in my neck and when this happens, a golf size knot comes up on the right side of my thyroid and gets really hard. It last for about 30 seconds.  Throat is dry.  I do not have any energy at all anymore.  I will sleep 14 hours and it feels like I have not slept for days.  The sono results are below.  Please give me your thoughts.  Thanks in advance.

The current study compared with the previous examination of 9/13/2010 shows the right lob to be 6.1x2.1x1.8cm.  There is a 0.8 cm hypoechoic complex nodule in the lower pole.

The left lobe of the gland measures 6.1x1.5x1.6cm. No discrete nodule or cyst in the left lobe is seen

The isthmus is 0.4cm with a 0.7 cm isoechoic nodule seen

Impression:  Enlarged gland with significant enlargement seen since the last study of 9/13/2010.  There is a single nodule in the right lobe and another nodule in the isthmus.

MRI uses gadolinium and not iodine.
There is no known risk to the thyroid.
Any change in the hashi/hypo status is likely unrelated.
