PET Scan: An Overview

Positron emission tomography (PET) is a painless, non-invasive medical imaging technique, widely used for detection cancer, heart disease and brain disorders such as dementia. This process involves detection of metabolism within bodily tissue, enabling construction of 3-dimensional images which show how organs and tissue in the body function, rather than producing an image that solelyContinue reading “PET Scan: An Overview”

Magnetic Resonance Imaging: Spinning Protons

The magnetic resonance imaging (MRI) scanner was first built in New York in 1977. It has since been vital to the advancement of neuroscience and understanding disorders in the brain. The scanner itself is an enormous magnet that produces a magnetic field which is over 10,000 times stronger than that of the Earth. This fieldContinue reading “Magnetic Resonance Imaging: Spinning Protons”
