Myelogram
|
|
Myelogram A specific X-ray study that uses an injection of a dye or contrast material into the spinal canal to allow careful evaluation of the spinal canal and nerve roots.
RELATED TERMS--------------------------------------
X-ray
Electromagnetic energy used to produce images of bones and internal organs onto film.
Injection
Medication which is put into the body via a syringe and a needle.
Contrast
"Short for ""contrast media."" Contrast media are X-ray dyes used to provide contrast, for example, between blood vessels and other tissue."
Nerve
Tissue that conveys sensation, temperature, position information to the brain.
SIMILAR TERMS--------------------------------------
Myelin
The lipid substance forming a sheath around the axons of certain nerve fibers.
Myelodysplastic Syndrome
A group of neoplasms that originate in a primitive multipotential hematopoietic cell.. About half of the cases are mild to moderate anemias accompanied by mild to moderately reduced white cell and platelet counts. Often, these are not progressive but they have a heightened propensity to evolve into acute myelogenous leukemia. The other half of the cases are a type of low blast count leukemia that may be associated with severe white cell and platelet deficits. Many of the patients affected require transfusion therapy, have a propensity to infection or to bleeding, and frequently progress to more overt leukemia.
Myeloid leukemia
One form of cancer of the blood-forming tissue, primarily the bone marrow and lymph nodes.
Myeloma
A tumour of plasma cells, generally secreting a single species of immunoglobulin.
PREVIOUS AND NEXT TERMS--------------------------------------
Myocardial infarction
Or heart attack. Occurs when one of more regions of the heart muscle experience a severe or prolonged decrease in oxygen supply caused by a blocked blood flow to the heart muscle.
Myocardial ischemia
Insufficient blood flow to part of the heart.
Myocardium
The muscle wall of the heart.
Myomectomy
Surgical procedure done to remove fibroids from the uterus, leaving the uterus intact.
Mycoplasma
Very common sexually transmitted disease or urinary tract infection caused by a bacteria-like organism in the urethra and reproductive system.
Myelogram
Male factor infertility
Condition in which a male patient is infertile for such reasons as very low sperm count, sperm that cannot swim properly, sperm that are unable to penetrate the egg, or blocked sperm ducts.
Methylation
A biochemical process involving the addition of chemical tags called methyl groups (-CH3) to DNA. Methylation can be a signal for a gene or a section of a chromosome to turn off gene expression and become inactive or "silent".
Minor H antigens
Or minor histocompatibility antigens. A group of proteins (in addition to those encoded by the major histocompatibility complex (MHC) that can cause transplant tissue rejection. Minor H antigens can cause tissue rejection even when donor and recipient are matched for MHC. Immune response to minor H antigens is far less potent than response to MHC-encoded proteins, so the rejection is a slower process.
Mitochondrial heteroplasmy
An atypical condition characterized by the presence of more than one type of mitochondrial DNA in a single individual. Normally, each individual has only one type of mitochondrial DNA, inherited from his or her mother through the egg at fertilization. (Mitochondria from the sperm are systematically eliminated by the egg at fertilization.)Cloned organisms may exhibit mitochondrial heteroplasmy (having a mixture of mitochondria from both the donor cell and the recipient egg) because this elimination system may be bypassed during the cloning process.
Mitochondrion
Plural: mitochondria. A cellular structure in the cytoplasm that provides energy to the cell. Each cell contains many mitochondria. In humans, a single mitochondrion contains 37 genes on a circular mitochondrial DNA, compared with about 35,000 genes contained in the nuclear DNA.
