Medical imaging is the technique and process of imaging the interior of a body for clinical analysis and medical intervention, as well as visual representation of the function of some organs or tissues ( physiology ). Medical imaging seeks to reveal internal structures hidden by the skin and bones, as well as to diagnose and treat disease.
The Visible Human Project is an effort to create a detailed data set of cross-sectional photographs of the human body, in order to facilitate anatomy visualization applications. It is used as a tool for the progression of medical findings, in which these findings link anatomy to its audiences. [ 1] A male and a female cadaver were cut into thin ...
Magnetic resonance imaging ( MRI) is a medical imaging technique used in radiology to form pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to generate images of the organs in the body. MRI does not involve X-rays or the use of ionizing ...
The first MR images of a human brain were obtained in 1978 by two groups of researchers at EMI Laboratories led by Ian Robert Young and Hugh Clow. [1] In 1986, Charles L. Dumoulin and Howard R. Hart at General Electric developed MR angiography, [2] and Denis Le Bihan obtained the first images and later patented diffusion MRI. [3]
History of neuroimaging. Neuroimaging is a medical technique that allows doctors and researchers to take pictures of the inner workings of the body or brain of a patient. It can show areas with heightened activity, areas with high or low blood flow, the structure of the patients brain/body, as well as certain abnormalities.
This study involved analyzing 242 head and neck and 519 pelvic computed tomography (CT) scans obtained from 8 different medical centers. These centers had diverse patient populations and used ...
The rainbow scale was used to code the PET images; radiotracer concentration is displayed from higher to lower as red > yellow > green > blue. [ 3 ] Before the use of functional magnetic resonance imaging (fMRI) became widespread, PET scanning was the preferred method of functional (as opposed to structural) brain imaging, and it still ...
Positron emission tomography ( PET) [ 1] is a functional imaging technique that uses radioactive substances known as radiotracers to visualize and measure changes in metabolic processes, and in other physiological activities including blood flow, regional chemical composition, and absorption. Different tracers are used for various imaging ...
