In the last few decades, obesity, hypertension and metabolic disorders have become the foremost health concerns for people in the developed countries. Due to this upward trend in metabolic syndrome (MS), researchers have investigated a variety of ways to measure adiposity in the population. Beyond body weight itself, two of the most common methods to measure obesity are body mass index (BMI) and abdominal circumference (AC) , and these measures are commonly used to determine obesity prevalence and incidence. However, neither of these simple non-imaging biomarkers allows the quantification and localization of fat into visceral and subcutaneous compartments, which are the bases for the progression of various metabolic conditions. Furthermore, BMI and other basic measures also fail to account for accumulation of fat within the liver. As we will discuss, nonalcoholic fatty liver disease (NAFLD) and non-alcoholic fatty pancreatic disease (NAFPD) are other important related conditions that are growing in prevalence and intersect with the other metabolic disorders. Certain cross-sectional techniques using ultrasonography (USG) computerized tomography (CT) and magnetic resonance (MR) imaging have shown to be highly effective for both the localization and quantification of visceral fat, which are important considerations in terms of MS. These imaging techniques can easily quantify and distinguish visceral fat from subcutaneous fat, and can also accurately quantify liver and pancreatic fat (steatosis). This is important because various studies have shown that MS, hepatic steatosis, NAFLD, visceral fat, and cardiovascular disease are all interrelated and share the common thread of fat aggregations contributing to disease progression. In this review we try to fi nd out ”were do we stand” at the moment with the diagnostic methods, to highlight the advantages of each of these imaging methods which are not competitors, but are complementary to each other. Although CT and MRI are generally more efficient, their price, low availability, the unability to continue immediatelly the clinical examination, make them second choice investigations, useful to complement an ultrasound exam. |
