APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -A PET scan requires a small amount of radioactive material (tracer). This tracer is given through a vein (IV), usually on the inside of your elbow. Or, you breathe in the radioactive material as a gas. The tracer travels through your blood and collects in organs and tissues.

Detailed explanation-2: -Magnetic resonance imaging (MRI) is a noninvasive test doctors use to diagnose medical conditions. MRI uses a powerful magnetic field, radiofrequency pulses, and a computer to produce detailed pictures of internal body structures. MRI does not use radiation (x-rays).

Detailed explanation-3: -An MRI scanner can create clear, detailed pictures of the structure of the brain and can detect any abnormalities or tumours.

Detailed explanation-4: -Advanced noninvasive neuroimaging techniques such as EEG and fMRI allow researchers to directly observe brain activities while subjects perform various perceptual, motor, and/or cognitive tasks.

Detailed explanation-5: -Magnetic resonance imaging is the structural imaging tool of choice. It is superior to radiographic CT in terms of both sensitivity and specificity for the identification of small lesions and abnormalities of the cerebral cortex.
