|
Detailed information on spinal tap, also called lumbar puncture A spinal tap, also called lumbar puncture, is done to measure the amount of pressure in the spinal canal and/or to remove a small amount of cerebral spinal fluid (CSF) for testing. Cerebral spinal fluid is the fluid that bathes your child's brain and spinal cord. In some cases, a spinal tap may also be done so medication can be injected into the spinal fluid, or to remove excess CSF in babies with hydrocephalus (a condition in which there is an overproduction or lack of absorption of the cerebral spinal fluid that is found inside the ventricles, fluid-filled areas, inside of the brain). A special needle will be used for the spinal tap.

A lumbar puncture is also called a spinal tap. A lumbar puncture may be used to look for problems in your brain, spinal cord, and related structures.

A biopsy is the removal of a small piece of tissue for laboratory examination.

|
|
A biopsy is a small sample of tissue or fluid taken from the body. This sample can then be studied in a laboratory. Image-guided biopsy allows a sample to be taken from an abnormal mass without the need for surgery. This procedure is done by a specially trained doctor called an interventional radiologist.

|
Detailed information on biopsy and the biopsy report For many health problems, a diagnosis is made by removing a sample of tissue for study in the pathology laboratory. The biopsy report describes the findings of a specimen.
