Thyroid Nodule Evaluation & FNA Biopsy

At District Endocrine, we provide timely, expert evaluation of thyroid nodules with in-office thyroid ultrasound and fine-needle aspiration (FNA) biopsy when needed. Our goal is to make the process efficient, convenient, and easy to understand so patients can get answers without unnecessary delays.

When appropriate, we also send thyroid biopsy samples for ThyroSeq molecular testing at the time of the FNA. This can provide additional information for indeterminate nodules, speed up decision-making, and in some cases avoid the need for a second biopsy.

Common Reasons Patients Are Referred

• Thyroid nodule found on ultrasound, CT scan, or MRI done for another reason
• Neck fullness, pressure, or trouble swallowing
• Enlarged thyroid or thyroid asymmetry on exam
• Follow-up of a previously known thyroid nodule
• Need for biopsy based on outside imaging findings

Our Evaluation Process

Careful Thyroid Nodule Assessment

We evaluate thyroid nodules using your history, symptoms, exam findings, prior imaging, and thyroid lab results. Because many nodules are benign, we focus on identifying which nodules can be safely monitored and which need closer evaluation — so that no unnecessary procedures are performed.

In-Office Thyroid Ultrasound

We offer in-office thyroid ultrasound to assess nodule size, structure, and other features that help determine risk. Having ultrasound available as part of your endocrine care allows for more efficient evaluation and better continuity of care — without the delays of separate imaging referrals.

FNA Biopsy with ThyroSeq Testing

If a thyroid nodule meets biopsy criteria, we perform fine-needle aspiration to obtain a tissue sample for analysis. When clinically appropriate, we also send the sample for ThyroSeq molecular testing at the same time. We are one of a limited number of practices that collect ThyroSeq samples during FNA — this can provide additional genetic information for indeterminate results, save time, and help avoid an extra procedure.

What Patients Can Expect

• Review of your thyroid history and prior imaging
• Detailed ultrasound-based evaluation of the nodule
• Clear discussion of whether biopsy is indicated
• Plain-language explanation of biopsy results and next steps
• Ongoing monitoring when long-term follow-up is appropriate

Personalized Follow-Up After Biopsy

A benign biopsy does not always mean no follow-up is needed, and an indeterminate result does not always mean surgery is required. We interpret biopsy results in context, monitor nodules over time with repeat imaging when appropriate, and coordinate next steps clearly so patients are never left confused about what the result means for them.

Coordination of Radioactive Iodine (RAI) Treatment

For patients with thyroid cancer or hyperthyroidism who require radioactive iodine therapy, we work collaboratively with Nuclear Medicine to coordinate RAI treatment as part of a comprehensive thyroid care plan.
