摘要

The purpose of this study was to examine the distribution of abdominal adipose tissue by magnetic resonance imaging (MRI). Thirty-six untrained healthy students (nineteen male and seventeen female) were recruited as subjects from the National Ping Tung Teachers College. All subjects were imaged on a 1.5 Tesla MRI (Signa Cvi, GE Medical System, Milwaukee, WI) scanner using a standard body coil at Kaohsiung Veterans General Hospital. The images were obtained 20 contiguous 10-mm axial Ti-weighted and set second image at the level of the umbilicus. All images were transferred to a personal computer using the Adobe Photoshop 7.0 and to calculate visceral adipose tissue (VAT), subcutaneous adipose tissue (SAT) and total adipose tissue (TAT) deposition. The results showed that the correlation between pixel counts by automated computer method and personal designed software were significantly correlated (r=0.997, p＜0.05). It showed that this method has acceptable precision. Also, the volumes obtained by the single umbilicus-level pixel and whole-abdominal fat were significantly correlated. (TAT r=0.91, SAT r=0.93, p＜0.05). This showed that the single umbilicus-level image value was an excellent measure for whole-abdomen values in this cohort. Single umbilicus-level image is easier and less expensive.
