ABDOMINAL FAT-EVALUATION BY USE OF SINGLE SCAN COMPUTED-TOMOGRAPHY

Purpose. Several studies emphasised the importance of the relationship between intraabdominal and total body adipose tissue as a risk factor for the development of metabolic or cardiovascular diseases. Therefor e, the aim of the present study was to examine whether a single scan c omputed tomography is able to determine the whole intraabdominal fat V olume with high accuracy and reproducibility. Materials and methods: R egions of interests (ROls) were drawn manually for measuring intraabdo minal fat in 51 unsuspicious abdominal CT. Results: The sexual differe ntiation of adipose tissue already described in a lot of studies could be confirmed in this study. Fat still predominates in females in lowe r half of the body(gynoid obesity). In men it predominates in the uppe r half (android obesity). Significant correlation concerning measuring the whole intraabdominal fat volume could be found in L1-level in wom en (r = 0.992) and in L2-level in men (r = 0.992). Measurement of a si ngle scan enables us to assess whole intraabdominal fat Volume due to a special formula. Conclusion: The determination of intraabdominal fat measured by a single scan computed tomography is a procedure associat ed with high accuracy and reproducibility.
