Prediction of Weight by Measuring Anterior Abdominal Wall Fats Using Computer Tomography

Abstract

The objective of this study is to predict the body weight by measuring Anterior Abdominal Fats Using CT Scans and providing the true weight for patients. This research also aims to evaluate the Component of Anterior Abdominal Wall Fat and correlating the findings With the Age and Gender. The Statistical Package for Social Sciences (SPSS, version24) program was used in order to analyze the primary data of the study. Both descriptive and inferential stats, e.g. regression and t tests, are employed in the study to examine the data and hypotheses. The data was collected in the period between December 2016 To April 2017. The study subjects were randomly drawn from patients referred to Ct Medical Centers in the State of Khartoum, namely: Almoalem Medical City- using Toshiba 160 Slices Device Type, Antalya Medical Center- using Ge 16 Slices Device Type, Modern Medical Center- using Ge 16 Slices Device Type, and Alzaytouna Specialist Hospital- using Toshiba 64 Slices Device Type. The study sample composed of 50 patients (28 Males, 22 Females), their age ranged between 10 and 85 years, body weights ranged between 30 and 130 Kg and had CT examination for abdomen done with or without contrast media used. The assessment of the clinical problems & medical history included: the indications of the study, contrast media allergies, renal impairment &who undergo CT abdomen for fasting 6 to 8 hours. The body weight of these patients was taken after the completion of the CT examination, measurements were made on the pancreatic level which was approximately 12-15cm long and is located deeply on the posterior abdominal wall. It lies approximately on the Trans pyloric plane (l1 vertebral level) and slopes upwards from right to left. Assuming that all CT devices/types are supported by the Arti Rad Dicom viewers programs, the measurements was taken from skin in right side of anterior abdominal wall to external oblique muscle, from skin in central to linea alba and from skin in left side to external oblique muscle for anterior abdominal fat wall thickness. And was also taken the measure from skin to anterior abdominal wall to posterior back skin and measured from right side skin of abdomen to left side skin of abdomen (circumference), with abdomen dimensions from CT image and correlate the findings with the age and gender of the subjects. This study concluded that the most affected ages were between 41 and 55 Years. The study found a significant link (p = 0.042) between Anteroposterior measurements and the age, i.e. the older the Age not relies to more the fat accumulation The R2 value (the "R Square" column) indicates how much of the total variation in the weight can be explained by age. In this case, only (0.1%) of variations in weight participated by age. Moreover, a significant relationship (p = 0.007) was also reported between the right & left measurements subcutaneous of Anterior Abdominal fat wall thickness. They were found to be equal because the fat distribution is equal by side of abdomen. Furthermore, a highly significant relationship (p = 0.00) between RT, Cen & LT Anterior Abdominal Subcutaneous Fat Thickness, it was equal for each. This result was justified based on the fact that Females have more fat compared to their males’ counterparts because physiologically they store more fat. That direct linear association between weight and anterior abdominal wall fat (right, center and left) in this relation the weight increase by 1.4, 0.91 and 1.1 respectively, the study also showed that, there a direct linear association between weight and RT/LT, and A/P ,and age in this relation the weight increase by 0.28, 0.187 and 0.037 respectively .
