Thyroid Check-up

Catch Thyroid Cancer Early
Thyroid Ultrasound & CT

Prime Radiology offers detailed thyroid exams using high-resolution ultrasound equipment. The thyroid is an important gland that regulates your body’s metabolism, so finding even small changes early and getting the right treatment matters. High-resolution ultrasound allows precise diagnosis of thyroid nodules, thyroiditis, thyroid dysfunction and thyroid cancer, and can accurately assess nodules as small as 5 mm or less. When ultrasound alone is not enough, a biopsy and blood tests can be added for an even more accurate diagnosis.

Precise diagnosis and fast results —
trusted thyroid imaging that protects your health and peace of mind.

Same-day exams are available, and unlike places that rush through, they looked at everything carefully. Thanks to them, my dad's exam went smoothly!
