Needle-localized biopsy is a procedure that uses very thin needles or guide wires to mark the location of an abnormal area of tissue so it can be surgically sampled. An imaging device such as an ultrasound probe is used to place the wire in or around the abnormal area. Needle localization is used when the doctor cannot feel the mass of abnormal ...
Needle aspiration biopsy is done with the rapid stabbing motion of the hand guiding a needle tipped syringe and the rapid sucking motion applied to the syringe. It is a method used to diagnose tumor deep in the skin or lymph nodes under the skin. The cellular aspirate is mounted on a glass slide and immediate diagnosis can be made with proper ...
Fine-needle aspiration. Fine-needle aspiration (FNA) is a percutaneous ("through the skin") procedure that uses a fine needle and a syringe to sample fluid from a breast cyst or remove clusters of cells from a solid mass. [6] It is mainly used to differentiate between a cyst and a mass. [6]
Stereotactic surgery is a minimally invasive form of surgical intervention that makes use of a three-dimensional coordinate system to locate small targets inside the body and to perform on them some action such as ablation, biopsy, lesion, injection, stimulation, implantation, radiosurgery (SRS), etc.
A biopsy procedure with a higher rate of cancer detection is template prostate mapping (TPM) or transperineal template-guided mapping biopsy (TTMB), whereby typically 50 to 60 samples are taken of the prostate through the outer skin between the rectum and scrotum, to thoroughly sample and map the entire prostate, through a template with holes ...
Immunofluorescence (IF) is a light microscopy-based technique that allows detection and localization of a wide variety of target biomolecules within a cell or tissue at a quantitative level. The technique utilizes the binding specificity of antibodies and antigens .

Fine-needle aspiration (FNA) is a diagnostic procedure used to investigate lumps or masses. In this technique, a thin (23–25 gauge (0.52 to 0.64 mm outer diameter)), hollow needle is inserted into the mass for sampling of cells that, after being stained , are examined under a microscope ( biopsy ).
