Magnetic Resonance Imaging (MRI)
57
Definition
Magnetic resonance imaging (MRI) Is primarily a medical imaging technique most commonly used in radiology to visualize the structure and function of the body.
Equipment Used
An MRI Scanner
How it Works
Radiofrequency fields are used to systematically alter the alignment of this magnetization, causing the hydrogen nuclei to produce a rotating magnetic field detectable by the scanner. This signal can be manipulated by additional magnetic fields to build up enough information to construct an image of the body. These detailed images can be used to determine body composition
Disadvantages
- Very costly
- Not publicly accessible
- Can take up to 30 minutes
Advantages
- Safe
- Non-invasive
Other Methods for Testing Body Fat
- Bioelectrical Impedance Analyzer (BIA)
This method measures electrical signals as they pass through the fat, lean mass, and water in the body. An undetectably low voltage is sent into the body usually via hands (handheld device) or feet (scale).... - Bod Pod (Air Displacement)
An air displacement plethysmography method that measures a person’s total body density (Db) by using the ratio of body mass to body volume (BV).Along with water displacement, air displacement is a form of... - Computed Tomography
A medical imaging method employing tomography. Also known as a CAT scan You lay on a CAT table Your arms will be raised above your head. After proper positioning, the technologist will move to the... - Dual Energy X-Ray Absorptiometry (DEXA)
This method is a three component model used to measure bone minerals, body fat, and muscle. How it Works A person lays on an x-ray table while two lose x-rays, one overhead and another underneath;... - Height and Circumference Measurements
This method uses a person’s height and circumference measurements of different body parts. Thus making this an Anthropometric method. Measure a person’s height and circumferences of different... - near Infrared Interactance (NIR)
This method is based on the principles of light absorption, reflectance, and near infrared spectroscopy. An infrared light is emitted onto an anatomical site, most commonly the biceps. The light passes... - Skinfold Measurements
A method that measures the thickness of a skinfold to get an estimate of body fat percent (BF%). The measurer typically uses the right side of a person’s body to measure from 3 to 9 different anatomical...
