Private Thyroid Ultrasound Scan in London: Nodules, Goitre, and Thyroid Health
You have noticed a lump or swelling in your neck. Your blood tests have come back showing abnormal thyroid function. Your GP has mentioned a thyroid nodule that needs imaging. Whatever the reason, waiting weeks for an NHS ultrasound while worrying about what might be wrong is unnecessary.
The Online GP by The Wellness offers same-day private thyroid and neck ultrasound from £195. Expert sonographers, state-of-the-art imaging, immediate preliminary results, and coordinated follow-up with our GP team — all under one roof.

Thyroid Nodules — Common and Usually Benign
Thyroid nodules are incredibly common. Ultrasound studies show that approximately 50% of adults have at least one thyroid nodule, though most people are unaware of them because they cause no symptoms. The overwhelming majority — roughly 95% — are benign.
However, the small percentage that are malignant make proper assessment essential. Thyroid cancer, while relatively rare, is the most rapidly increasing cancer in the UK, with approximately 3,900 new cases diagnosed each year. Early detection leads to excellent outcomes, with five-year survival rates above 90% for most thyroid cancers.
Ultrasound is the single most important investigation for thyroid nodules. It determines the size, number, and characteristics of nodules, and identifies features that distinguish likely benign nodules from those needing further investigation.
How Thyroid Nodules Are Classified
The TI-RADS (Thyroid Imaging Reporting and Data System) classifies nodules based on their ultrasound features.
TI-RADS 1 (Normal) — no nodules found. TI-RADS 2 (Benign) — simple cysts and spongiform nodules with classic benign features. TI-RADS 3 (Mildly suspicious) — nodules with some features that warrant monitoring. TI-RADS 4 (Moderately suspicious) — nodules with suspicious features that may require fine needle aspiration (FNA) biopsy. TI-RADS 5 (Highly suspicious) — nodules with multiple concerning features strongly suggesting malignancy.
Our sonographers classify every thyroid nodule according to TI-RADS, providing your GP and any specialist with a standardised, internationally recognised assessment.
Goitre
A goitre is an enlarged thyroid gland — a visible or palpable swelling in the front of the neck. Goitres can be caused by iodine deficiency (rare in the UK), autoimmune thyroid disease (Hashimoto's or Graves' disease), multinodular goitre (multiple nodules causing overall enlargement), thyroiditis (inflammation), or, rarely, thyroid cancer.
Ultrasound determines whether the goitre is diffuse (uniformly enlarged) or nodular (containing discrete nodules), measures the overall thyroid size, and identifies any nodules that need further assessment. Combined with thyroid blood tests, ultrasound guides the management plan.
Neck Lumps
Not all neck lumps are thyroid-related. Our thyroid and neck ultrasound also assesses cervical lymph nodes (which can enlarge due to infection, inflammation, or, less commonly, lymphoma or metastatic cancer), salivary gland swellings (parotid and submandibular glands), lipomas and sebaceous cysts, and other soft tissue masses.
Any persistent neck lump lasting more than 3 weeks should be investigated. This is particularly important in adults over 40, smokers, people with a history of head and neck cancer, and anyone with associated symptoms such as hoarseness, difficulty swallowing, or unexplained weight loss.

Combined Thyroid Assessment
The most informative approach to thyroid health combines ultrasound with blood tests. Our GP team can arrange both on the same visit. A comprehensive thyroid blood panel includes TSH, free T4, free T3, and thyroid antibodies (TPO and TgAb). This assesses thyroid function, while ultrasound assesses structure. Together, they provide the complete picture.
For example, a patient with fatigue and weight gain might have blood tests showing elevated TSH (hypothyroidism) and an ultrasound showing a diffusely enlarged thyroid with a heterogeneous texture — consistent with Hashimoto's thyroiditis. Or a patient with a palpable nodule might have normal blood tests but an ultrasound showing a TI-RADS 4 nodule requiring biopsy. Neither investigation alone tells the full story.
What Happens After Your Scan
If your thyroid ultrasound is completely normal, you receive reassurance and a clear report. If nodules are found but appear benign (TI-RADS 2), we advise on any follow-up scanning needed. If nodules have features requiring further assessment (TI-RADS 3-5), we arrange specialist referral to an endocrinologist or ENT surgeon for fine needle aspiration biopsy or further management. If thyroid blood tests are abnormal, we initiate treatment or referral as appropriate.
Every result is reviewed by our GP team. Every finding is explained clearly. Every next step is arranged.
