In brief: Not reliable
It can give you some clues about hypo or hyper but it cannot tell you for sure about thyroid function.
The only test to do that is the blood test.

In brief: Thyroid ultrasound
Thyroid ultrasound is done when there is enlargement of thyroid gland, or goiter.
Goiter may be accompanied with hypothyroid or hyperthyroid condition and thyroid adenoma or nodule.

In brief: No
The thyroid ultrasound is not a good test to look for hypo or hyperthyroidism, but it can give information about why a person is hypothyroid or hyperthyroid.
Hyperthyroidism can be due to 1) graves' disease, which often has an enlarged thyroid with increased blood flow, or a 'toxic' nodule. Hypothyroidism is often due to hashimoto's thyroiditis, with a mottled, or 'heterogenous' appearance.
