Aims and objectives
Increased intraabdominal visceral fatplays an important and etiologic role in metabolic disorders,
cardiac diseases and increased all-cause mortality (1,2,3,4).
Abdominal fat measurement with quantitative computed tomography (QCT) is a useful tool for evaluation of metabolic disorders (5,1,6,7,8). Several studies revealed that visceral fat area measurement from a single slice is a reliable method and highly correlated with the total visceral fat volume (1,6,9,10,11,12,13,14).
On the other hand,
borders of fat measurement were not described in the literature by all means.
To the best of our...
Methods and materials
Study Participants
Patients who have been admitted to Endocrinology Department of Dokuz Eylul University for the investigation of incidentally discovered adrenal tumours between2008 and 2017 were included in our study.
Patients with adrenocortical carcinomas,
metastasis or active malignancy were excluded.
A concomitant endocrinological investigation identified nonfunctioning adrenal adenomas,
subclinical Cushing's syndrome or Cushing's syndrome in recruited individuals.
CT investigations of these patients were selected.
130 patients were found according to these criterias.
One patient was excluded who has CT of positron emission tomography (PET) investigation...
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...
Conclusion
Fat measurement with QCT is a validated technique (5,
1,
6,
7,
8,
12).
On the other hand,
there are limitations in this method.
Due to defined HU limits for fat measurement,
there are falsely highlighted areas in theintestinal lumen.
These falsely highlighted areas are usually fecal material or liquid in intestinal lumen with intermediate density.To the best of our knowledge,
there is only one study in the literature that pays attention to these falsely highlighted areas.
Hung et al.
(15) were excluded all intestinal...
