> What the terms in a thyroid ultrasound report mean — size, echogenicity, nodules, TIRADS, lymph nodes and what happens next.

A thyroid ultrasound report contains descriptive terms that can be difficult to interpret without context. Understanding the structure of the report helps you ask better questions at your appointment.
The report describes appearance and risk; it does not by itself diagnose cancer.

## Gland size and texture

The report usually gives the size of each lobe and the isthmus, and describes the texture (echogenicity). A diffusely enlarged gland may suggest goitre or thyroiditis; a heterogeneous texture can be seen in Hashimoto’s.
Increased blood flow may be noted, but this is non-specific.

## Nodule description

For each nodule, the report describes size, composition (solid, cystic or mixed), echogenicity, shape, margins, calcification and vascularity. These features are combined into a risk category in some systems, such as TIRADS.
Higher-risk features include irregular margins, taller-than-wide shape, marked hypoechogenicity and microcalcifications.

## Lymph nodes

The neck lymph nodes are often assessed. Normal nodes are small and bean-shaped; enlarged, rounded or abnormal-looking nodes may prompt biopsy.

## What happens next

The report is interpreted with your thyroid function tests and examination. A low-risk nodule may simply be monitored; a higher-risk nodule may need FNAC. The report itself is not a diagnosis.

## Frequently asked questions

### What does TIRADS mean?

TIRADS is a risk-stratification system that categorises nodules from benign-appearing to highly suspicious based on ultrasound features.

### Does a suspicious ultrasound mean cancer?

No — it means the nodule has features that warrant further assessment, usually biopsy. Most nodules are still benign.

### How often should nodules be monitored?

It depends on the nodule’s features and size — often every 6–12 months initially, then less frequently if stable.
