Rectal biopsy
Rectal biopsy can be used to determine the cause of blood, mucus, or pus in the stool. Rectal biopsy can also confirm findings of another test or x-rays, or take a biopsy of a growth found in the colon.

Mucosal biopsy
Mucosal skin biopsy is the removal of a small piece of skin or mucous membrane. The sample can be retrieved in several ways: a shave biopsy (scraping or shaving a thin layer), a punch biopsy (using a needle or punch to obtain a small, but deeper, sample), or an excision of tissue (cutting to remove a piece of tissue). The sample is sent to the laboratory to isolate and identify organisms that cause infection.

Head CT
CT stands for computerized tomography. In this procedure, a thin X-ray beam is rotated around the area of the body to be visualized. Using very complicated mathematical processes called algorithms, the computer is able to generate a 3-D image of a section through the body. CT scans are very detailed and provide excellent information for the physician.

Bone biopsy
A bone biopsy is performed by making a small incision into the skin. A biopsy needle retrieves a sample of bone and it is sent for examination. The most common reasons for bone lesion biopsy are to distinguish between benign and malignant bone tumors, and to identify other bone abnormalities. Bone biopsy may also be performed to determine the cause of bone pain and tenderness.

Muscle biopsy
A muscle biopsy involves removal of a plug of tissue usually by a needle to be later used for examination. Sometimes more than one needle insertion may be needed to obtain a large enough specimen. If there is a patchy condition expected an open biopsy may be used. Open biopsy involves a small incision through the skin and into the muscle, so that a sample of muscle tissue can be removed from the affected area. There may be some slight bruising or bleeding at the site but the risks are minimal with the procedure.

Sentinel node biopsy
Sentinel node biopsy is a technique which helps determine if a cancer has spread (metastasized), or is contained locally. When a cancer has been detected, often the next step is to find the lymph node closest to the tumor site and retrieve it for analysis. The concept of the "sentinel" node, or the first node to drain the area of the cancer, allows a more accurate staging of the cancer, and leaves unaffected nodes behind to continue the important job of draining fluids. The procedure involves the injection of a dye (sometimes mildly radioactive) to pinpoint the lymph node which is closest to the cancer site. Sentinel node biopsy is used to stage many kinds of cancer, including lung and skin (melanoma).

Pleural biopsy
In a pleural biopsy, a small piece of pleural tissue in the chest is removed with a needle. The biopsy may distinguish between a cancerous and noncancerous disease. It also can help to detect whether a viral, fungal or parasitic disease is present.

Nasal biopsy
A nasal biopsy is a diagnostic procedure in which a small piece of tissue is removed from the mucosal lining of the nose. The biopsy is most often performed when abnormal tissue is observed during an examination of the nose, or when disorders affecting the nasal mucosal tissue are suspected.

Nerve biopsy
Nerve biopsy is the removal of a small piece of nerve for examination. Through a small incision, a sample of nerve is removed and examined under a microscope. Nerve biopsy may be performed to identify nerve degeneration, identify inflammatory nerve conditions (neuropathies), or to confirm specific diagnoses.
