A biopsy is the removal of a small piece of tissue for microscopic examination and/or culture, often to help the physician make a diagnosis.
|
|
A biopsy is the removal of a small portion of tissue from the body for microscopic examination. When a physician diagnoses the nature of an ailment, various examinations provide information that is vital to accurately determining the nature of the problem.
|
|
Detailed information on biopsy, including the most common types of biopsy such as endoscopic biopsy, bone marrow biopsy, excisional biopsy, incisional biopsy, fine needle aspiration biopsy, punch biopsy, shave biopsy, and skin biopsy
|
 |
Biopsy is a diagnostic procedure in which a piece of tissue and/or cells are removed to be examined under a microscope by a pathologist. Purpose Biopsies are performed to determine the presence of cancer cells, establish tumor grading , and provide more information for treatment.

 |
Esophagogastroduodenoscopy (EGD) is an examination of the lining of the esophagus, stomach, and upper duodenum with a small camera (flexible endoscope) which is inserted down the throat.
|
|
An esophagogastroduodenoscopy (EGD), which is also known as an upper endoscopy or upper gastrointestinal endoscopy, is a diagnostic procedure that is performed to view the esophagus, stomach, and duodenum (part of the small intestine). In an EGD, the doctor uses an endoscope, a flexible, tube-like, telescopic instrument with a tiny camera mounted at its tip, to examine images of the upper digestive tract displayed on a monitor in the examination room.
|
 |
An endoscope as used in the field of gastroenterology (the medical study of the stomach and intestines) is a thin, flexible tube that uses a lens or miniature camera to view various areas of the gastrointestinal tract. When the procedure is limited to the examination of the inside of the gastrointestinal tract ' s upper portion, it is called upper endoscopy or esphagogastroduodenoscopy (EGD).
|
|
An esophagogastroduodenoscopy (EGD), or upper endoscopy, is a procedure in which a camera mounted on a small flexible tube is used to view the esophagus, stomach , and duodenum (part of the small intestine ). Small instruments may also be passed through the tube to treat disorders or biopsy lesions.

A fecal occult blood test (FOBT) is a noninvasive test that detects the presence of hidden (occult) blood in the stool. Such blood may arise from anywhere along the digestive tract. Hidden blood in stool is often the first, and in many cases the only, warning sign that a person has colorectal disease, including colon cancer . There are two types of FOBTs: 1) the traditional guaiac smear test (Hemoccult, Seracult, Coloscreen), and 2) the newer, flushable reagent pads (EZ DetectT, ColoCARE). They are both useful in detecting hidden blood in the stool, and are mainly used for colorectal cancer screening. The tests differ in the way they are performed. The flushable reagent pads are available without a prescription at many drugstores. In contrast, the traditional guaiac smear test is completed and interpreted by a medical professional, and these tests are usually available from a laboratory or a doctor's office. Many consumers prefer the flushable reagent pads because there is no stool handling and no laboratory processing. However, health care providers usually favor the guaiac tests because the large studies that have shown the benefits of colon cancer screening were done with guaiac tests.

The fecal occult blood test (FOBT) is performed as part of the routine physical examination during the examination of the rectum. It is used to detect microscopic blood in the stool and is a screening tool for colorectal cancer .

Everything You Need to Know About a Fecal Occult Blood Test (FOBT)Sometimes cancers or polyps bleed. An FOBT checks for blood in your stool.

|
The fecal occult blood test (FOBT) is a rapid test for detecting the presence of blood hidden in the stool and caused by gastrointestinal bleeding. Purpose This test is performed to detect the presence of blood in the feces.

Stool specimen collection is the process of obtaining a sample of a patient's feces for diagnosic purposes. Purpose This procedure is used to test for infectious organisms, mucus, fat, parasites, or blood in the stool.

Colon cancer is the second leading cause of cancer deaths in the United States. An estimated 147,000 new cases will be diagnosed this year. About 57,000 people will die from the disease.

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)

A chest MRI uses powerful magnets and radio waves to construct pictures of the body. Unlike conventional radiography and computed tomographic (CT) imaging, which make use of potentially harmful radiation (x-rays) that passes through a patient to generate images, magnetic resonance imaging (MRI) is based on the magnetic properties of atoms. A powerful magnet generates a magnetic field roughly 10,000 times stronger than the Earth's. A very small percentage of hydrogen atoms within the body will align with this field. Radio wave pulses are broadcast towards the aligned hydrogen atoms in tissues of interest, returning a signal of their own. The subtle differing characteristics of that signal from different tissues enables MRI to differentiate between various organs, and potentially, provide contrast between benign and malignant tissue. Any imaging plane, or "slice", can be projected, and then stored in a computer or printed on film. MRI can easily be performed through clothing and bones, however, certain types of metal in or around the area of interest can cause significant errors in the reconstructed images.

Nuclear radiology is a sub-specialty of radiology in which radioisotopes (compounds containing radioactive forms of atoms) are introduced into the body for the purpose of imaging, evaluating organ function, or localizing disease or tumors. Unlike conventional or computed radiography (such as plain x-rays and CT scans) in which x-ray beams are generated within a machine and projected through the patient, in isotope studies the radiation (gamma rays) originates from within a radiopharmaceutical (material tagged with a radioisotope ) in the body. Special detector cameras are placed close against the area of interest for a period of time, and once enough gamma rays are "seen," a computer creates an image showing where the isotope localized within the organ or body. Generally, nuclear medicine scans do not provide the level of anatomic detail seen on x-ray, ultrasound, CT, or MR images. However, correlation with other imaging, clinical information, and laboratory results helps identify and confirm disease. See bone scan , nuclear ventriculography (MUGA or RNV), pulmonary ventilation/perfusion scan , thyroid scan , lung scan , and renal 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.

 |
Positron emission tomography (PET) is a non-invasive scanning technique that utilizes small amounts of radioactive positrons (positively charged particles) to visualize body function and metabolism . Purpose As of 2001, PET is the fastest growing nuclear medicine tool in terms of increasing acceptance and applications.
