In brief: Gets tissue sample

This technique uses a non invasive ultrasound machine to see where the needle is traveling in the body in order to obtain a sample of tissue.
Aspiration usually refers to obtaining fluid from a joint or a mass (cyst) in the body.

...more like removing a group of cells (an aspirate) from the region of interest; can be done with or without ultrasound (or any other imaging assistance) guidance.

In brief: Obtain cell samples.

A fine needle (25G or 27G size) is inserted into the area of concern, after applying local anesthesia, under continuous real-time ultrasound scanning.
Once inside the region of interest, suction is applied while the needle is moved back and forth several times. The needle is then removed and its content spread on a glass slide, which is then "fixed" and "stained' for interpretation.

In brief: Mini Biopsy

The area to be biopsied is visualized with sono.
The skin is prepped, the sono probe is covered with a sterile sleeve. Under constant ultrasound guidance, a small bore needle (20g or less) is advanced to the lesion and multiple passes made, usually with the needle hooked up to a syringe with suction applied. Aspirated material is placed in formalin or smeared onto slides to pathology for disgnosis.
