Body Composition
A deeper dive into your health with your whole body MRI scan, with detailed insights into body fat, muscle volume and symmetry, and abdominal organ volume, including population comparisons. Our AI-powered Body Composition report provides body composition metrics generated by our FDA-cleared medical device software, leveraging our dataset of tens of thousands of patient scans. The best part? It doesn’t require additional MRI scan time.
Prenuvo’s Body Composition report provides a detailed body composition profile.
Fat Analysis
Fat volume analysis (including visceral, subcutaneous, and liver fat) provides fat distribution throughout the body.
Muscle Analysis
Detailed insights into lower body muscle volume and symmetry, which is a strong predictor of health, including longevity, mobility, and the risk of disability and chronic conditions.
Organ Volume Analysis
Includes volume analysis for abdominal organs including your liver, kidneys, and spleen.
The combined power of whole body screening, coupled with body composition metrics, for a more holistic view of your health:
Chronic Disease Risk
Visceral fat, subcutaneous fat, liver fat, and muscle volume are critical biomarkers that may be tracked to inform decision-making that may help reduce the risk of certain chronic diseases or conditions, such as cardiovascular disease, metabolic disorders like diabetes, and numerous other chronic diseases.
Lifestyle Interventions
Track the impact of changes to your diet or exercise routine on your whole body (including your body composition), or see how your body composition changes over time.
Comparison Populations
Easy to read graphs highlight how your values compare vs. similar patients, leveraging our large dataset of whole body imaging.
Frequently asked questions
The subcutaneous fat calculation includes analysis of the chest / torso and lower body; visceral fat volume analyzes the abdomen.
the liver, stomach, and intestines, considered more dangerous to health than subcutaneous fat (fat just under the skin) as it is pro-inflammatory and can increase the risk of chronic diseases like diabetes and heart disease when present in excessive amounts; it's often referred to as "belly fat" that can't be seen but is located around internal organs. Subcutaneous fat is a type of body fat that is stored just beneath the skin. It is visible and can be felt when pinching the skin, and is distributed through the body. It insulates the body and regulates temperature, provides cushioning and protection for organs and muscles, and stores energy.
Muscle volume asymmetry refers to a noticeable difference in the size or volume of muscles between the left and right sides of the body, essentially meaning one side has significantly more muscle mass than the other. Symmetry between the left and right sides of the body is helpful for optimal biomechanics, injury prevention, posture, functional efficiency, and peak athletic performance.
Muscle volume / symmetry analysis includes lower body muscles only; volume & symmetry analysis of the chest, core muscles, and arms are not included at this time..
Your percentile values are compared against patients with similar biological sex and age, and normalized by height.
If you have certain medical conditions, the Body Composition report may be inaccurate. These conditions include, but are not limited to, the following:
Hemochromatosis or hemosiderosis of the liver
History of a liver transplant
Situs inversus (a rare condition where major organs are reversed from their normal positions)
Numerous liver cysts, polycystic liver disease, autosomal dominant polycystic kidney disease (ADPKD) with liver cysts, or Caroli disease (a rare disorder affecting the bile ducts)
Sickle Cell Disease or Gaucher’s disease
A muscle-wasting disease or a lipodystrophy
A splenic rupture within the last 12 months"
Our body composition analysis uses MRI to generate body composition measurements, which research suggests1 offers superior accuracy for measurements like visceral, subcutaneous and liver fat volume and muscle volume - without exposure to harmful ionizing radiation. MRI provides a more precise three-dimensional image of soft tissues like fat and muscle, while DEXA primarily measures bone density and provides a less detailed breakdown of body composition. A DEXA scan also exposes patients to a small amount of radiation. While the amount of radiation exposure from a DEXA scan is very low compared to other imaging tests, it can be something to consider if you are getting scanned frequently or seeking to minimize overall radiation exposure.
