The Claim
In adults with newly diagnosed thyrotoxicosis, a peak systolic velocity of the inferior thyroid artery greater than 38 cm/s measured by color flow Doppler ultrasound is strongly associated with Graves' disease rather than destructive thyroiditis, with 96.8% sensitivity and 98.6% specificity.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In adults newly diagnosed with an overactive thyroid, a blood flow measurement above 38 cm/s in the inferior thyroid artery using ultrasound reliably distinguishes Graves' disease from destructive thyroiditis.

In adults with newly diagnosed thyrotoxicosis, a peak systolic velocity of the inferior thyroid artery greater than 38 cm/s measured by color flow Doppler ultrasound is strongly associated with Graves' disease rather than destructive thyroiditis, with 96.8% sensitivity and 98.6% specificity, suggesting it may serve as a non-invasive alternative to radioactive iodine scans.
Antibodies bind to thyroid cells and force them to produce excessive hormones, which increases the gland's metabolic demand and causes new blood vessels to form. This floods the thyroid with blood, making the blood flow through its main feeding artery much faster.
What the research says
1 studyThis study found that measuring how fast blood flows in the arteries near the thyroid with a simple ultrasound can tell doctors if someone has Graves' disease instead of another cause of an overactive thyroid — and it’s super accurate, with almost no mistakes.
