Biopsy / Fine Needle Aspirations

Biopsy/Fine Needle Aspirations/ Core Biopsy/Fluid Drainage

A radiologist can perform the following procedures so that diagnostic samples may be sent to a pathology practice to be examined.


Your radiologist will take a sample of tissue, using a biopsy needle. This method is commonly used for breast lesions and lymph nodes.

Fine Needle Aspiration

A very fine needle is passed through an area of interest by the radiologist to gather a sample of cells that will be placed on slides for examination. This method is often used for thyroids, breast lesions and lymph nodes.

Fluid Aspirations

Using a needle and syringe, fluid can be removed from joints such as the knee, bakers’ cysts, ganglions and breast cysts. Sometimes this is sent for diagnostic tests, but more often than not just the drainage is performed.


Some aftercare is required after most procedures. It is suggested that you rest for 24 to 48 hours afterwards. If required, our reception staff can provide you a notice of attendance for your employer, though if you need a medical certificate you will need to discuss this with your referrer.

The radiologist or their assistant will advise you of when to take any dressings off. It can take up to two weeks for any pain relief to take effect, in some very rare occasions you may not receive any relief from these procedures.

If you have any concerns after an interventional procedure, including a reaction, infection or excessive bleeding please contact your referring physician as soon as you are able.
