Results
246 abdominal CT of 129 patients (99 female,
30 male) were evaluated with QCT.
Totally 481 measurements (246 measurements for visceral fat evaluation and 235 measurements for subcutaneous fat evaluation) were performed.
118 patients had two CT investigation in different times and 11 patients had only one CT investigation.
Visceral fat evaluation with QCT was performed in all 246 abdominal CT.
The subcutaneous fat measurement was performed in 235 CT.
In 11 CT abdomen borders were not totally include the CT investigation due to morbid obesity of the patients.
To avoid the possible misdiagnosis subcutaneous fat measurement was not performed in these CT investigations with incomplete visualization of the subcutaneous fat.
Although measurements with two different methods(method 1 and method 2) are strongly correlated(r>0,9),
Passing and Bablock regression analysis indicated systematic and proportional error between measurements; the 95%CI for the intercept A does not contain the value 0 and the 95%CI for slope B does not contain the value 1 in the regression model.
Also paired sample T-test was performed and statistically significant difference was found between measurements (p<0,001).
