Quantitative Analysis
Neck to Thigh Ratio
The thyroid gland is present and entirely suprasternal. The left lobe is mildly larger compared to the right.
There is markedly increased and diffuse uptake of radiotracer throughout the thyroid gland of 4.9% (Normal 0.5-2.0). The neck-to-thigh ratio is also elevated measuring 32.
There is a focal region of decreased radiotracer uptake within the mid-pole region of the left thyroid gland which indicates a hypo-functioning/cold nodule.
Recommendation:
The hypo-functioning or cold nodule corresponds to the focal mid-pole TR4 lesion identified on the above ultrasound and a fine needle aspirate was recommended.
