MRI effective for assessment of body composition in at-risk obese individuals

Spain: A team of researchers from Spain have reported magnetic resonance imaging (MRI) to be just as effective as computed tomography (CT) for assessing body composition in obese patients at risk for type 2 diabetes mellitus (T2DM), cardiovascular disease (CVD), and nonalcoholic fatty liver. The findings were published in the most recent issue of Current Opinions of Clinical Nutrition and Metabolism.
Juan Manuel Alcantara, the Public University of Navarre in Pamploma, Spain, and colleagues, however, note the additional benefit of MRI of not exposing patients to radiation.
There has been an exponential increase in the prevalence of obesity during the past years. The evaluation of human adipose tissue distribution enables the identification of diverse ectopic adipose tissue depots and helps to explain its relationship with cardiovascular health status.
For evaluating a person's body composition, there are non-imaging-based techniques -- such as bioelectrical impedance or skinfold thickness analysis, and other imaging modalities such as DEXA (dual-energy x-ray absorptiometry) and ultrasound -- but clinicians have been turning more and more to MRI to evaluate fat distribution because of its high accuracy.
In the review, the researchers team summarized the current methods used in the assessment of human adipose tissue distribution. They discussed the relationship between ectopic adipose tissue distribution and the risk of developing CVDs and metabolic complications.
Key findings of the review:
· The reference instruments to assess human adipose tissue distribution nowadays are computed tomography and MRI.
· MRI is the preferred imaging technique and enables the measurement of variations in the distribution of body adipose tissue among different phenotypes and individuals. This technique has helped in better understanding the relationship between different ectopic adipose tissue depots and its relationship with cardiometabolic health among individuals.
"Although body composition can be assessed by simple techniques, these calculations can provide erroneous conclusions and results, needing complex interpretations when diverse metabolic situations are concomitantly engaged," the researchers wrote.
They added, "contrarily, medical imaging techniques (e.g. MRI) enable to objectively and unbiasedly measure changes that may occur during longitudinal studies (e.g. pharmacological drug interventions)."
"The review offers a useful primer for defining a patient's fatty tissue deposits and thus risk of disease," they concluded.
