Your Pathologist Does the Scan, the Biopsy and the Diagnosis
Quick answer: AR Diagnostics in Houston performs ultrasound-guided fine needle aspiration (FNA) biopsy of thyroid nodules and breast lumps, and core needle biopsy of the breast.

- The scan: your pathologist performs the ultrasound to find and assess the nodule or lump.
- The biopsy: guided by ultrasound, your pathologist collects the sample with a thin needle.
- The read: your pathologist examines the sample under the microscope (rapid on-site evaluation, or ROSE) to confirm it has enough material, and then makes the diagnosis.

Does My Nodule or Lump Need a Biopsy?
Thyroid nodules are common, most are benign, and not every nodule needs a biopsy. The ACR TI-RADS criteria, shown in the image below, are usually used to determine whether a nodule is recommended for biopsy.
Step 1: Score five ultrasound features
Cystic or almost completely cystic: 0
Spongiform: 0
Mixed cystic and solid: 1
Solid or almost completely solid: 2
Anechoic: 0
Hyperechoic or isoechoic: 1
Hypoechoic: 2
Very hypoechoic: 3
Wider-than-tall: 0
Taller-than-wide: 3
Smooth: 0
Ill-defined: 0
Lobulated or irregular: 2
Extra-thyroidal extension: 3
None or large comet-tail artifacts: 0
Macrocalcifications: 1
Peripheral (rim) calcifications: 2
Punctate echogenic foci: 3
Step 2: Add up the points to get the TI-RADS level (TR)
0 points
Benign
No FNA
2 points
Not suspicious
No FNA
3 points
Mildly suspicious
FNA if 2.5 cm or larger; follow-up ultrasound if 1.5 cm or larger
4 to 6 points
Moderately suspicious
FNA if 1.5 cm or larger; follow-up ultrasound if 1 cm or larger
7 or more points
Highly suspicious
FNA if 1 cm or larger; follow-up ultrasound if 0.5 cm or larger (yearly for up to 5 years)
A spongiform nodule scores 0 and no other points are added. For echogenic foci, add the points for each type that is seen. Educational information only: the doctor who reads your ultrasound assigns the TI-RADS level, and your own doctor decides whether you need a biopsy or follow-up.

Breast findings on mammogram and ultrasound are described with the BI-RADS system. Your physician will recommend whether a biopsy is right for you.

I had an a great experience with Dr. Siddiqi. His thoroughness through the procedure itself and genuine concern were evident as he checked in on my healing progress and explained my test results in a detailed and understandable manner. I felt well-cared for throughout the entire process. Dr. Siddiqi’s practice manager Reenum played a crucial role. Her assistance in the whole process helped me feel at ease. As a first timer, her support made the entire experience more comfortable. I highly recommend this place!
