The nucleus of an atom has nucleons and the protons collectively known as nucleon. The mass number is the total number of nucleons present in a nucleus. A nuclide has the following composition, Atomic number denoted by Z, the neutron number denoted by N and the mass number denoted by A. isotopes are atomic species having identical properties in chemical composition (Z) but different mass numbers (A). The atom’s outermost orbital electrons are involved in the chemical reactions and the chemical behavior will not change when the compound is labeled with radioactive isotope. In addition, the nuclear radioactive characteristics are not affected by the chemical composition of the atom. When a small volume of a system comprises of numerous particles that are confined together, then the system becomes unstable. An unstable nucleus then becomes stable by transforming itself through emission of particles and photons. This process is what is termed as radioactive decay, and when the nuclides undergo through a similar process, it is called radionuclide. The radioactivity studies form the basis to understand the atomic nucleus. Initial unstable nucleus in the decay of radioactive nuclides is known as the parent and daughter is the final nucleus that is more
Emission Tomography is a medical imaging branch that comprises of Position Emission Tomography Techniques (PETT) and the Single Photon Emission Computed Tomography (SPECT). The Emission Tomography images the characteristics of a physiological body by use of radioactive…
When a low energy positron collides with a low energy electron, there is an emittance of two gamma rays in the opposite direction. This phenomenon, also called positron annihilation, results in two gamma rays at 180° and with 0.511 MeV of energy moving in opposite directions.
As a way of settling the dispute and controversy (some even calling to abandon it altogether), the Board of Trustees of the Society for Personality Assessment has issued a statement containing evidence and rational argument in support of the Rorschach. With the backing of advanced research methods, the psychometric adequacy and clinical utility of the instrument is convincingly proven, making a strong case for its continued use in clinical and forensic practice.
Magnetic Resonance Imaging is among the most popularly deployed clinical diagnostic tools, which works by making use of a “strong magnetic field” to produce “high- resolution anatomical information with excellent soft-tissue contrast”.
The capability to image the human body, equally to spot disease and direct surgery, has become cardinal to the implementation of medicine. In the resulting time, radiology has burgeoned to cover the use of many faces of electromagnetic radiation in making increasingly dominant diagnostic images of the body and diseases.
Wildlife is on the decline, and many species get extinct frequently. This alarming situation has resulted in renewed efforts to preserve wildlife. Some of the technical tools employed in this effort are voice recorders, satellite telemetry, manned
I, in this paper, discuss the major developments that have been realized by the nation’s health care facilities in the period and major drivers to the progress.
The 20th century was rich in innovations and discoveries that included identification of diseases and approaches to
The paper first gives the definition of the two clinical tools and then moves on to give a brief description about their individual uses. Later on the paper will discuss about the scenario when two modalities will be fused into a single
The current diagnostic strategies adopt the use of technology to enhance efficiency, selectivity and prediction of results. For instance, Positron Emission Tomography (PET) allows the rebuilding of cross-sectional images under examination. The rationale for the principle involves depiction of the biodistribution of substances used as PET tracers
