Lymph node biopsy is a test in which a lymph node or a piece of a lymph node is removed for examination under a microscope. The lymphatic system is made up of lymph nodes connected by lymph vessels. The nodes produce white blood cells (lymphocytes) that fight infections. When an infection is present, the lymph nodes swell, produce more white blood cells, and attempt to trap the organisms that are causing the infection. The lymph nodes also try to trap cancer cells.
|
 |
A lymph node biopsy is a procedure in which all or part of a lymph node is removed and examined to determine if there is cancer within the node. Lymph node biopsy is a procedure in which a sample of lymph node tissue is removed for laboratory analysis.

Bone marrow is the tissue that makes blood cells. It is found in the hollow part of most bones. Bone marrow aspiration is the removal of this tissue for examination. See also: Bone marrow biopsy; Bone marrow culture.
|
|
|
A bone marrow biopsy is the removal of soft tissue from inside bone. Bone marrow grows inside some of the larger bones in the body. It produces platelets and red and white blood cells.
|
 |
A complete blood count (CBC) test measures the following: The number of red blood cells (RBCs; The number of white blood cells (WBCs; The total amount of hemoglobin in the blood; The fraction of the blood composed of red blood cells (hematocrit; The mean corpuscular volume (MCV) - the size of the red blood cells. CBC also includes information about the red blood cells that is calculated from the other measurements: MCH (mean corpuscular hemoglobin; MCHC (mean corpuscular hemoglobin concentration.
The platelet count is also usually included in the CBC.
|
 |
One of the most commonly ordered clinical laboratory tests, a blood count, also called a complete blood count (CBC), is a basic evaluation of the cells (red blood cells, white blood cells, and platelets) suspended in the liquid part of the blood (plasma). It involves determining the numbers, concentrations, and conditions of the different types of blood cells.
|
 |
A complete blood count (CBC) is a series of tests used to evaluate the composition and concentration of the cellular components of blood. It consists of the following tests: red blood cell (RBC) count, white blood cell (WBC) count, and platelet count; measurement of hemoglobin and mean red cell volume; classification of white blood cells (WBC differential); and calculation of hematocrit and red blood cell indices .
|
|
The clinical laboratory test that evaluates the three main cellular components of peripheral blood (red cells, white cells, and platelets) is called the " complete blood count " (CBC). It is used commonly to assess whether a patient is anemic (low red cell count), has an infection (increased white blood cells), or has abnormal blood coagulation (platelet levels).

Computed tomography (CT) of the chest is performed to diagnose a variety of symptoms, including vascular, cardiac, airway disease as well as cancers that can occur in the thoracic region of the body. Purpose The purpose of the CT scan is to noninvasively and quickly visualize internal organs which may be damaged by disease or trauma.

An abdominal CT scan is an imaging method that uses x-rays to create cross-sectional pictures of the belly area. CT stands for computed tomography. See also: CT scan
|
 |
A chest tomogram is a picture of the chest area created by moving the x-ray machine in one direction while moving the recording film the other way. This method blurs structures in front of and behind the area of the chest being studied.

Computed tomography (CT) an imaging method that uses x-rays to create cross-sectional pictures of the body.
|
 |
Computed tomography (CT) scans are completed with the use of a 360-degree x-ray beam and computer production of images. These scans allow for cross- sectional views of body organs and tissues.
|
|
Neck pain is a nonspecific symptom of discomfort that has a number of possible causes. Depending on the cause, neck pain may be experienced as limited to the neck itself (localized), or as radiating to the shoulders and upper arm.
|
 |
Computed tomography (also known as CT, CT scan, CAT, or computerized axial tomography) scans use x rays to produce precise cross-sectional images of anatomical structures. With the development of modern computers, the scans enhanced digital capabilities allowed the development of computed tomography imaging (derived from the Greek tomos , meaning " to slice " ).
|
 |
A laparotomy is a large incision made into the abdomen. Exploratory laparotomy is used to visualize and examine the structures inside of the abdominal cavity.

 |
A gallium scan is a test that uses radioactive material to look for infection in the body. It is a type of nuclear medicine exam.
|
|
A gallium scan of the body is a nuclear medicine test that is conducted using a camera that detects gallium, a form of radionuclide, or radioactive chemical substance. Purpose Most gallium scans are ordered to detect cancerous tumors, infections, or areas of inflammation in the body.
|
|
A gallium scan of the body is a diagnostic imaging test that utilizes a radionuclide, Ga67, to detect areas of infection and inflammation, or to detect certain types of tumors. Purpose In cases where patients have a suspected infection or inflammation, a gallium scan is useful to establish the site of origin, particularly with bone or orthopedic infections, and with such diseases as sarcoidosis.

During a physical examination, a health care provider studies a patient's body to determine the presence or absence of physical problems. A typical physical examination includes: Inspection (looking at the body; Palpation (feeling the body with hands; Auscultation (listening to sounds; Percussion (producing sounds.

The liver is a pyramid-shaped organ that lies within the upper right side of the abdomen. In a typical liver biopsy, a needle is inserted through the rib cage or abdominal wall. The needle goes into the liver to take a sample for examination. The procedure can also be performed by inserting a needle into the jugular vein. A catheter is then passed through the veins, down to the liver, to take the sample.
|
|
A liver biopsy is a medical procedure performed to obtain a small piece of liver tissue for diagnostic testing. The sample is examined under a microscope by a doctor who specializes in the effects of disease on body tissues (a pathologist) to detect abnormalities of the liver.

A lymphangiogram is a special x-ray of the lymph nodes and lymph vessels. Lymph nodes produce white blood cells (lymphocytes) that help fight infections. The lymph nodes also filter and trap cancer cells. The lymph nodes and vessels are not usually seen on a normal x-ray, so a dye or radioisotope (radioactive compound) is injected into the body to highlight the area being studied.
|
 |
Lymphangiography is a type of diagnostic testing technique in which x rays (called lymph node angiograms) and the injection of a contrast medium (a substance that provides a contrast between the tissue or organ being filmed and the medium) are used to visualize lymphatic circulation and the lymph nodes. Purpose The lymphatic system consists of tissues, organs, and vessels that aid in circulating body fluids and defending the body from damage by foreign substances such as viruses, bacteria, or fungi.
|
|
Lymphangiography, or lymph node angiogram, is a test which utilizes x-ray technology, along with the injection of a contrast agent, to view lymphatic circulation and lymph nodes for diagnostic purposes. Purpose The lymphatic system is a one way circulation that channels tissue fluid back into the heart.

Positron emission tomography (PET) is an imaging test that uses a radioactive substance (called a tracer) to look for disease in the body. Unlike magnetic resonance imaging (MRI) and computed tomography (CT) scans, which reveal the structure of organs, a PET scan shows how the organs and tissues are functioning. See also: Bone scan; Lung scan; Nuclear ventriculography; Pulmonary ventilation/perfusion scan; Renal scan; Thyroid scan.
|
 |
Positron emission tomography (PET) is a highly specialized imaging technique using short-lived radiolabeled substances to produce powerful images of the body ' s biological function. Purpose Besides being used to investigate the metabolism of normal organs, PET has also become the technique of choice to investigate various neurological diseases and disorders, including stroke, epilepsy, Alzheimer ' s disease, Parkinson ' s disease, and Huntington ' s disease.
|
|
Rather than showing the structure of a body part, PET images show the chemical function of an organ or tissue. PET can show changes in how an organ or tissue works. This can help your healthcare provider diagnose problems and develop a treatment plan for you.
