Which radioactive isotope is used in brain operation?
High-specific-activity (HSA) Co-60 is used for brain cancer treatment.
Which radioisotope is used to detect brain tumors?
The procedure involves the injection of a radioactive isotope (such as technetium-99m or iodine-131) into a blood vessel that supplies the cranial region.
What are the three types of radioisotopes?
What are some commonly-used radioisotopes?
|Hydrogen-3 (tritium)||12.32 years|
Why is Cobalt 60 used?
Co-60 is used medically for radiation therapy as implants and as an external source of radiation exposure. It is used industrially in leveling gauges and to x-ray welding seams and other structural elements to detect flaws. Co-60 also is used for food irradiation, a sterilization process.
Are radioactive isotopes used in MRI?
When used in medical practices, radioisotopes are used particularly for diagnosis and therapy of various medical conditions. In regards to diagnoses, the isotopes are used in conjunction with scanning machines such as MRI, CT scans, and others, to image and diagnose disorders that couldn’t otherwise be seen.
What is radioisotope give example?
(a).The isotopes which are unstable due to presence of extra neutrons in their nuclei and emit various types of radiations, are called radioactive isotopes or radioisotopes. For example: Carbon – 14 , Arsenic – 74. (b). Uses of isotopes- (i).
How many radioisotopes are there?
While there are 254 stable isotopes, more than 3,000 radioisotopes are known, of which only about 84 are seen in nature. The radiation emitted is energetic and can be of different types, most often alpha (a), beta (b) and gamma (g).
What does a radioisotope do?
An unstable form of a chemical element that releases radiation as it breaks down and becomes more stable. Radioisotopes may occur in nature or be made in a laboratory. In medicine, they are used in imaging tests and in treatment. Also called radionuclide.
What is the diagram of the brain and its functions?
Diagram of the Brain and its Functions. In most respects, the left and the right sides of the brain are symmetrical. However, there is one major difference, in most people, the left hemisphere is more involved in language and creativeness, while the right side is more involved in understanding and judgment.
How useful is the diagram of the brain for class 10-12?
The diagram of the brain is useful for both Class 10 and 12. It is one among the few topics having the highest weightage of marks and is frequently asked in the examinations. A well-labelled diagram of a human brain is given below for further reference. The human brain is divided into three main parts:
What are the cerebral hemispheres of the brain?
This consists of the two cerebral hemispheres of the cerebrum and their inter connections. The cerebrum is the largest part of the brain. Any kind of trauma or lesion in the cerebrum can lead to various diseases and disorders and mental illnesses. The cerebrum is divided into two cerebral hemispheres by the medial longitudinal fissure.
What part of the brain controls the left and right hemisphere?
The right hemisphere controls the left side of the body, and the left half controls the right side of the body. The two halves communicate with one another through a large, C-shaped structure of white matter and nerve pathways called the corpus callosum. The corpus callosum is in the center of the cerebrum.
