Diagnostic and Non-Surgical Treatment Procedures

_________________________________________

Biopsy (B):

Removal of tissue from a living body for diagnostic purposes. The term has also been used to describe the tissue being submitted for evaluation

Guided biopsy:

Using computed tomography or ultrasonography to guide an instrument to the selected area for tissue removal

Surface biopsy (B/S):

Removal of tissue brushed, scraped or obtained by an impression smear from the intact or cut surface of tissue in question

Needle aspiration (B/NA):

Removal of tissue by application of suction through a hollow needle attached to a syringe

Needle biopsy (B/NB):

Removal of tissue by puncture with a hollow needle

Core needle biopsy (B/CN):

Removal of tissue with a large hollow needle that extracts a core of tissue

Bite biopsy (B/B):

Removal of tissue by closing the opposing ends of an instrument

Punch biopsy (B/P):

Removal of tissue by a punch-type instrument

Incisional biopsy (B/I)

Removal of a selected portion of tissue by means of the surgical cutting

Excisional biopsy (B/E):

Removal of the entire tissue in question by means of surgical cutting Guided biopsy – Using computed tomography or ultrasonography to guide an instrument to the selected area for tissue removal

Radiotherapy (RTH):

Use of ionizing radiation to control or kill tumor cells; also called radiation therapy

Chemotherapy (CTH):

Use of cytotoxic anti-neoplastic drugs (chemotherapeutic agents) to control or kill tumor cells

Immunotherapy (ITH):

Use of the immune system to control or kill tumor cells

Radiography (RAD):

Two-dimensional imaging of dental, periodontal, oral and maxillofacial structures using an X-ray machine and radiographic films, sensor pads or phosphor plates

Computed tomography (CT):

A method of medical imaging that uses computer-processed X-rays to produce tomographic images or ‘slices’ of specific areas of the body; digital geometry processing is used to generate three-dimensional images of an object of interest from a large series of two-dimensional X-ray images taken around a single axis of rotation

Cone-beam CT (CT/CB):

Variation of traditional CT that rotates around the patient, capturing data using a cone-shaped X-ray beam

Magnetic resonance imaging (MRI):

A method of medical imaging that uses the property of nuclear magnetic resonance to image nuclei of atoms inside the body

Ultrasonography (US):

A method of medical imaging of deep structures of the body by recording the echoes of pulses of ultrasonic waves directed into the tissues and reflected by tissue planes where there is a change in density

Scintigraphy (SCI):

A method of medical imaging that uses radioisotopes taken internally (e.g., by mouth, injection, inhalation), and the emitted radiation is captured by external detectors (gamma cameras) to form two-dimensional images
