Cone Biopsy: From 2 Different Sources

A surgical procedure in which a conical or cylindrical section of the lower part of the cervix is removed. A cone biopsy is performed after an abnormal cervical smear test result if the exact precancerous or cancerous area (see cervix, cancer of) cannot be identified by colposcopy.

surgical removal, by knife or laser, of a cone-shaped segment of tissue from the cervix of the uterus. It may be performed if a cervical biopsy (see colposcopy) reveals evidence of cervical carcinoma in situ (*cervical intraepithelial neoplasia type 3): the abnormal tissue is removed and examined microscopically for confirmation of complete removal of the abnormality.

A surgical process in which a small piece of tissue is cut out or otherwise sampled, e.g. through a needle biopsy, to enable a diagnosis to be made.... biopsy

Cone

(1) A light-sensitive cell in the retina of the EYE that can also distinguish colours. The other type of light-sensitive cell is called a rod. There are around six million cones in the human retina and these are thought to comprise three types that are sensitive to the three primary colours of red, blue, and green.

Jejunal Biopsy

A diagnostic test in which a small piece of tissue is removed from the lining of the jejunum for microscopic examination.

It is especially useful in the diagnosis of Crohn’s disease, coeliac disease, lymphoma, and other causes of malabsorption.

The biopsy is taken using an endoscope passed down the throat into the small intestine, via the stomach.... jejunal biopsy

Cone Shells

Molluscs with cone-shaped shells, at least two species of which (Conus geographicus and C. textile) have been responsible for some 18 human deaths, usually from respiratory arrest. C. geographicus has caused at least one Australian death.... cone shells

Excision Biopsy

A biopsy of a lesion for the purposes of diagnosis in which the whole lesion is exc ised.... excision biopsy

Biopsy Samples

are analysed by staining, in which Abnormal area dyes are used to Normal to show up structures or identify constituents such as antibodies or enzymes. A tissue sample may be tested with specific antibodies in the investigation of infection and inflammation. In some cases, a tis-sue culture may be required.... biopsy samples

Bone Marrow Biopsy

A procedure to obtain a sample of cells from the bone marrow (aspiration biopsy) or a small core of bone with marrow inside (trephine biopsy). The sample is usually taken, under local anaesthesia, from the sternum (breastbone) or iliac crests (upper part of the hip-bones). Microscopic examination gives information on the development of the blood components

surrounding tissues. Radionuclide scanning detects areas throughout the skeleton in which there is high bone-cell activity. This type of scanning and on the presence of cells foreign to the marrow.

It is useful in the diagnosis of many blood disorders, including leukaemia and anaemia.

It can also show whether bone marrow has been invaded by lymphoma or cells from other tumours.... bone marrow biopsy

Kidney Biopsy

A procedure in which a small sample of kidney tissue is removed and examined under a microscope.

Kidney biopsy is performed to investigate and diagnose serious kidney disorders, such as glomerulonephritis, proteinuria, nephrotic syndrome, and acute kidney failure, or to assess the kidneys’ response to treatment.

There are 2 basic techniques: percutaneous needle biopsy, in which a hollow needle is passed through the skin into the kidney under local anaesthesia; and open surgery under general anaesthesia.... kidney biopsy

Liver Biopsy

A diagnostic test in which a small sample of tissue is removed from the liver, usually under local anaesthesia. The main function of this test is to diagnose liver diseases. (See also biopsy.)... liver biopsy

Renal Biopsy

See kidney biopsy.... renal biopsy

Skin Biopsy

Removal of a portion of skin for laboratory analysis in order to diagnose a skin disorder.... skin biopsy

Cone Beam

see image-guided radiotherapy.... cone beam

Plugged Biopsy

an *interventional radiology technique in which, after taking a sample of tissue (biopsy) to check for cancer cells or abnormality, the tract of the biopsy needle is plugged with materials to prevent bleeding at the site. It is mostly used for liver and renal biopsies.... plugged biopsy
