Figure 1: The lipid bilayer and the structure and composition of a glycerophospholipid molecule. (A) The plasma membrane of a cell is a bilayer of glycerophospholipid molecules. (B) A single glycerophospholipid molecule is composed of two major regions: a hydrophilic head (green) and hydrophobic tails (purple). (C) The subregions of a glycerophospholipid molecule; phosphatidylcholine is shown as an example.
What is magnetic resonance imaging (MRI)? Magnetic resonance imaging (MRI) is a diagnostic procedure that uses a combination of a large magnet, radiofrequencies, and a computer to produce detailed images of organs and structures within the body. Unlike X-rays or computed tomography (CT scans), MRI does not use ionizing radiation.
Magnetic resonance imaging (MRI) is a diagnostic medical tool that uses a magnetic field and radio wave energy to produce images of the human body. An MRI technologist works in this area of specialty in radiology.Read on for more information about what an MRI technologist does.agnetic resonance imaging (MRI) is a diagnostic medical tool that uses a magnetic field and radio wave energy to produce images of the human body.
