Lumbar puncture Increased intracranial pressure is a contraindication, due to risk of cerebellar tonsils herniation. Under some circumstances, lumbar puncture cannot be performed safely (e.g. a severe bleeding tendency). It is regarded as a safe procedure, but post-dural-puncture headache is common. The procedure is typically performed under local anesthesia and aseptic technique. A needle is used to access the subarachnoid space and fluid collected. Fluid may be sent for biochemical, microbiological, and cytological analysis.

- Small biopsies obtained by core needle or bronchoscopy are commonly used for diagnosis of lung nodules. Several features help to distinguish benign conditions from possible lung cancer. The first parameter is the size of the lesion: the smaller, the less risk for malignant cancer.

Lumbar puncture ( spinal tap) Lumbar puncture (spinal tap) Overview. A lumbar puncture (LP), also called a spinal tap, is an invasive outpatient procedure used to remove a sample of cerebrospinal fluid (CSF) from the subarachnoid space in the spine. (This test is similar to a blood test, in which a needle is inserted into an artery to collect blood for testing.)

- A lumbar puncture may also be done to: 1  Put anesthetics or medicines into the CSF. Medicines may be injected to treat leukemia and other types of cancer of the central nervous system. 2  Put a dye in the CSF that makes the spinal cord and fluid clearer on X-ray pictures (myelogram).

Lumbar puncture (spinal tap) Though lumbar puncture is generally recognized as safe, it does carry some risks. These include: Post-lumbar puncture headache. Up to 25 percent of people who have undergone a lumbar puncture develop a headache afterward due to a leak of fluid into nearby tissues. The headache typically starts several hours up to two days after the procedure and may be accompanied by nausea, vomiting and dizziness.

- How it is performed. Lumbar punctures are carried out in hospital. This may be after an emergency admission, or the procedure may be arranged in advance. Before a lumbar puncture, checks will be made to confirm the procedure is safe for you. Usually a computerised tomography (CT) scan or an magnetic resonance imaging (MRI) scan will have been carried out to make sure the lumbar puncture is needed and will not cause any harm.

Lumbar Puncture A spinal tap (also called a lumbar puncture) is a medical test that involves taking a small sample of cerebrospinal fluid (CSF) for examination. Cerebrospinal fluid is a clear, colorless liquid that delivers nutrients to the brain and spinal cord and cushions them for protection. In a spinal tap, a doctor carefully inserts a needle between the bones of the lower spine to collect a sample of this fluid.

Multiplanar MRI assists rectal cancer detection and staging Multiplanar MRI assists rectal cancer detection and staging. February 07, 2005. Rectal cancer is a common cause of death in Europe and the U.S. Prognosis is directly related to the extent of extramural spread in the mesorectum at the time of diagnosis and to surgical clearance at circumferential resection margins.1.

Understanding Cancer -- Diagnosis and Treatment Understanding Cancer -- Diagnosis and Treatment. The earlier cancer is diagnosed and treated, the better the chance of its being cured. Some types of cancer -- such as those of the skin, breast, mouth, testicles, prostate, and rectum -- may be detected by routine self-exam or other screening measures before the symptoms become serious. Most cases of cancer are detected and diagnosed after a tumor can be felt or when other symptoms develop. In a few cases, cancer is diagnosed incidentally as a result of evaluating or treating other medical conditions. Cancer diagnosis begins with a thorough physical exam and a complete medical history.
