Serum pepsinogen and gastric cancer screening. (1/3)

Since the 1990's, the test for serum pepsinogen as a marker for chronic atrophic gastritis has been incorporated into gastric cancer screening programs, on a trial basis, to identify people at high risk for gastric cancer. The addition of the serum test to the cancer screening program has been shown to improve the detection rate of cancer and pepsinogen testing is useful in detecting early-stage gastric cancers arising from atrophic gastric mucosa, which macroscopically tend to be elevated and histologically differentiated. Furthermore, the cost for the detection of a single cancer case is much less than that for conventional screening. Thus, with the introduction of pepsinogen testing, complimenting barium X-ray, a more efficient screening system is available.  (+info)

Room-temperature semiconductor detectors for in vivo monitoring of internal contamination. (3/3)

In vivo monitoring of low-energy X-ray and gamma-ray emitters has always been a difficult task, primarily because of lack of accuracy and the high detection limits of classical techniques. Various types of PIN diodes (diodes with a large intrinsic zone) were tested in the Radiation Protection Department of the Studie Centrum voor Kernenergie, Centre d'etude de l'Energie Nucleaire (Mol, Belgium) in the measurement of radioactive body burden by direct methods. Current research is oriented toward the use of room-temperature diodes for the detection of low-energy photons escaping the body. In this paper, a new counting technique that involves a portable jacket containing the diodes is described. The system uses silicon diodes and is used out of shielding room in order to be near the contamination. With this method rapid analysis and long counting times are possible, stress is reduced, and medical treatment can be optimized. CdZnTe detectors were also evaluated for this measurement technique but this type of detector is better adapted for counting inside a shielding room. The improvement of the accuracy of the measurement, taking into account the effect of the ribs, is described here, as well the associated electronics necessary for this type of counting.  (+info)

Barium radioisotopes are radioactive forms of the element barium, which are used in medical imaging procedures to help diagnose various conditions. The radioisotopes emit gamma rays that can be detected by external devices, allowing doctors to visualize the inside of the body. Barium sulfate is often used as a contrast agent in X-rays and CT scans, but when combined with a radioisotope such as barium-133, barium-198, or barium-207, it can provide more detailed images of specific organs or systems.

For example, barium sulfate mixed with barium-133 may be used in a lung scan to help diagnose pulmonary embolism or other respiratory conditions. Barium-207 is sometimes used in bone scans to detect fractures, tumors, or infections.

It's important to note that the use of radioisotopes carries some risks, including exposure to radiation and potential allergic reactions to the barium compound. However, these risks are generally considered low compared to the benefits of accurate diagnosis and effective treatment.

Barium sulfate is a medication that is commonly used as a contrast material in medical imaging procedures, such as X-rays and CT scans. It works by coating the inside of the digestive tract, making it visible on an X-ray or CT scan and allowing doctors to see detailed images of the stomach, intestines, and other parts of the digestive system.

Barium sulfate is a white, chalky powder that is mixed with water to create a thick, milky liquid. It is generally safe and does not cause significant side effects when used in medical imaging procedures. However, it should not be taken by individuals who have a known allergy to barium or who have certain digestive conditions, such as obstructions or perforations of the bowel.

It's important to note that while barium sulfate is an important tool for medical diagnosis, it is not a treatment for any medical condition and should only be used under the direction of a healthcare professional.

Barium is a naturally occurring, silvery-white metallic chemical element with the symbol Ba and atomic number 56. In medical terms, barium is commonly used as a contrast agent in radiology, particularly in X-ray examinations such as an upper GI series or barium enema. The barium sulfate powder is mixed with water to create a liquid or thick paste that is swallowed or inserted through the rectum. This provides a white coating on the inside lining of the digestive tract, allowing it to be seen more clearly on X-ray images and helping doctors diagnose various conditions such as ulcers, tumors, or inflammation.

It's important to note that barium is not absorbed by the body and does not cause any harm when used in medical imaging procedures. However, if it is accidentally inhaled or aspirated into the lungs during administration, it can cause chemical pneumonitis, a potentially serious condition. Therefore, it should only be administered under the supervision of trained medical professionals.

Radioisotopes, also known as radioactive isotopes or radionuclides, are variants of chemical elements that have unstable nuclei and emit radiation in the form of alpha particles, beta particles, gamma rays, or conversion electrons. These isotopes are formed when an element's nucleus undergoes natural or artificial radioactive decay.

Radioisotopes can be produced through various processes, including nuclear fission, nuclear fusion, and particle bombardment in a cyclotron or other types of particle accelerators. They have a wide range of applications in medicine, industry, agriculture, research, and energy production. In the medical field, radioisotopes are used for diagnostic imaging, radiation therapy, and in the labeling of molecules for research purposes.

It is important to note that handling and using radioisotopes requires proper training, safety measures, and regulatory compliance due to their ionizing radiation properties, which can pose potential health risks if not handled correctly.

Zinc radioisotopes are unstable isotopes or variants of the element zinc that undergo radioactive decay, emitting radiation in the process. These isotopes have a different number of neutrons than the stable isotope of zinc (zinc-64), which contributes to their instability and tendency to decay.

Examples of zinc radioisotopes include zinc-65, zinc-70, and zinc-72. These isotopes are often used in medical research and diagnostic procedures due to their ability to emit gamma rays or positrons, which can be detected using specialized equipment.

Zinc radioisotopes may be used as tracers to study the metabolism and distribution of zinc in the body, or as therapeutic agents to deliver targeted radiation therapy to cancer cells. However, it is important to note that the use of radioisotopes carries potential risks, including exposure to ionizing radiation and the potential for damage to healthy tissues.

Barium compounds are inorganic substances that contain the metallic element barium (Ba) combined with one or more other elements. Barium is an alkaline earth metal that is highly reactive and toxic in its pure form. However, when bound with other elements to form barium compounds, it can be used safely for various medical and industrial purposes.

In medicine, barium compounds are commonly used as a contrast material for X-ray examinations of the digestive system. When a patient swallows a preparation containing barium sulfate, the dense compound coats the lining of the esophagus, stomach, and intestines, making them visible on an X-ray image. This allows doctors to diagnose conditions such as ulcers, tumors, or blockages in the digestive tract.

Other barium compounds include barium carbonate, barium chloride, and barium hydroxide, which are used in various industrial applications such as drilling muds, flame retardants, and pigments for paints and plastics. However, these compounds can be toxic if ingested or inhaled, so they must be handled with care.
