Prenuvo Body Composition Analysis
Understand how your body is built and what it’s building toward
Prenuvo’s FDA-cleared Body Composition Analysis helps you better understand how your body is made up by measuring different types of tissue. Using MRI technology, it separates and quantifies visceral fat around your organs, subcutaneous fat under the skin, liver fat, and skeletal muscle. This detailed information can give you a clearer picture of your body’s composition and support more informed conversations about your health and wellness goals.
Your Body Composition Analysis Report is powered by FDA-cleared software that uses AI technology to analyze your results. This report is included with every scan, providing measurements of key body composition details.

What to expect from your Body Composition Analysis Report
Once your scan results are ready, you’ll receive an invitation to review your Prenuvo Body Composition Analysis Report with a Prenuvo provider. During this appointment, you’ll receive clear explanations, annotated images, and easy to understand insights to help you better understand your results. You will receive a copy of your report after completing your Prenuvo Results Review appointment with a Prenuvo provider.

Volume Calculations
Volume calculations for visceral and subcutaneous fat, lower body muscles, and abdominal organs.

Liver Fat Insights
Liver fat percent and grade, visual heat map of liver fat distribution.

Muscle Asymmetry
Highlights differences between the left and right sides of your lower body, which may influence balance, movement, and overall function.
How to book
Prenuvo Body Composition Analysis
Our proprietary FDA-cleared medical software and AI-learning algorithm that provides a detailed analysis of your body’s muscle mass, symmetry, body fat, and organ volume to help track changes or health insights tied to excess visceral fat or muscle loss.
Includes
- Fat volume analysis (including visceral, subcutaneous and liver fat)
- Muscle volume, with detailed insights into lower body muscle volume and symmetry analysis
- Abdominal organ volume analysis (liver, kidneys, spleen)
Frequently asked questions
The subcutaneous fat calculation includes analysis of the chest / torso and lower body; visceral fat volume analyzes the abdomen.
- Visceral fat is fat stored deep inside the abdomen, surrounding organs such as the liver, stomach, and intestines. It’s sometimes called “hidden” belly fat because you can’t see or feel it from the outside. Higher amounts of visceral fat have been associated with increased inflammation and a greater risk of chronic conditions like heart disease and diabetes.
- Subcutaneous fat is fat stored just beneath the skin. It’s the type of fat you can see and pinch. Subcutaneous fat helps insulate the body, cushion muscles and organs, and store energy. While all fat plays a role in the body, where it’s stored can influence overall health risk.
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, helping detect irregular muscle and nerve injuries or atrophy, and peak athletic performance.
To ensure the highest quality, all reports undergo a rigorous quality control process. If the data does not meet these standards, results will not be provided to avoid sharing potentially inaccurate information. In these cases, your payment for this component will be proactively refunded as part of our commitment to delivering the highest quality service.
A reporting failure of a Body Composition Analysis Report does not affect the validity of the scan itself, or other components. All other results will be delivered as expected.
Certain conditions, such as a history of joint replacements or device implants, may interfere with the Body Composition Analysis technology. Occasionally, a Body Composition Analysis may not meet quality control standards for other reasons like movement during image acquisition, or anatomical irregularities.
Informational Purpose: A Body Composition Analysis is intended as a wellness tool and should not be used as a substitute for clinical evaluation.
No, unfortunately a total body fat percentage isn't calculated as we are not directly measuring bone or upper body muscle volumes which would be necessary for a total body fat percentage calculation.
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.
Our Body Composition Analysis is intended for individuals 18 years and older. It may not be appropriate for people with certain medical conditions that can affect measurement accuracy.
These conditions include, but are not limited to:
- Hemochromatosis or hemosiderosis affecting the liver
- A history of liver transplant
- Situs inversus (or any other rare conditions where major organs are positioned differently than usual)
- Numerous liver cysts, polycystic liver disease, autosomal dominant polycystic kidney disease (ADPKD) with liver cysts, or Caroli disease
- Sickle cell disease or Gaucher’s disease
- A muscle-wasting disease or a lipodystrophy
- A splenic rupture within the last 12 months
If you have any of these conditions or are unsure whether Body Composition Analysis is right for you, please speak with your healthcare provider or a Prenuvo team member before scheduling.
Our Body Composition Analysis uses MRI screening to generate body composition measurements, which research suggests1 offers accuracy for measurements like visceral, subcutaneous and liver fat volume and muscle volume, without exposure to harmful ionizing radiation. MRI provides a precise three-dimensional image of soft tissues like fat and muscle, while DEXA primarily measures bone density (not currently assessed by MRI) 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.
