Stereotactic biopsy, also known as stereotactic core biopsy, is a biopsy procedure that uses a computer and imaging performed in at least two planes to localize a target lesion (such as a tumor or microcalcifications in the breast) in three-dimensional space and guide the removal of tissue for examination by a pathologist under a microscope.
Stereotactic biopsy is done with the help of a specialized device, which provides mammographic guidance. For a stereotactic biopsy, morbid obesity is a relative contraindication due to weight limitations of the devices. Pregnancy and breast compression size may also be contraindications depending on the modality being used. [15]
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.
Ultrasound is also used surgically. Specifically, an ultrasound-guided needle biopsy allows providers to see the needle so it can be directed toward the lesion of concern while avoiding other critical structures such as blood vessels. [40] Ultrasound-guided biopsies have also been shown to decrease re-excision and mastectomy rates in breast cancer.
Schematic representation of a vacuum-assisted biopsy probe. Mammotome is a Cincinnati, Ohio–based company who pioneered a vacuum-assisted breast biopsy (VAC) device that uses image guidance such as x-ray, ultrasound and/or MRI to perform breast biopsies. A biopsy using a Mammotome® device can be done on an outpatient basis with a local ...
Breast biopsy may also be performed using a different modality, such as ultrasound or magnetic resonance imaging (MRI). While radiologists [ 12 ] had hoped for more marked improvement, the effectiveness of digital mammography was found comparable to traditional X-ray methods in 2004, though there may be reduced radiation with the technique and ...
Focused-ultrasound-mediated diagnostics or FUS-mediated diagnostics are an area of clinical diagnostic tools that use ultrasound to detect diseases and cancers. Although ultrasound has been used for imaging in various settings, focused-ultrasound refers to the detection of specific cells and biomarkers under flow combining ultrasound with lasers, microbubbles, and imaging techniques.
A newer type of breast biopsy technique is the stereotactic biopsy which relies on a three-dimensional X-ray to guide the needle of non-palpable mass. The biopsy is performed in a similar manner, by using a needle to remove a tissue sample, but locating the specific area of the breast is done by X-raying the breast from two different angles.
