Measurement of Liver Size and Factors Affecting it by Using CT or Ultrasonography

Aim. We sought to determine the size and Factors Effecting it by Using CT or Ultrasonography. Methods. Review used the descriptive-normative research design in recording, describing, interpreting, analyzing and comparing updated data from authoritative sources. Data were evaluated descriptively. The influence of multiple variables on liver size was assessed by means of a covariance analysis. Results. The ten sources found, analyzed, compared and recommended the use of different factors, which effect liver size and span. These are gender, age, BMI, and body surface area and various methods, such as CT and PET scans, ultrasound and anthropometrical equipment. Taking into account the vital role of the liver in ensuring the continued survival on the human body, this has resulted in various attempts to study more about the organ in question and to examine its various functions. Using the descriptive-normative approach, the researchers for this study were able to examine the following findings pertaining to factors affecting liver size. First, the primary factor identified by the various studies as having potential influence on liver size and volume was biological sex, which was also cited as having a similar influence on standard uptake value (SUV). To a lesser extent, it was also noted that age and body mass had observable effects on liver size. Liver span, meanwhile, was noted as being best predicted by height and body surface area, while BMI and height were noted as predictors of liver diameter. Conclusion: The Liver volume assessed with CT scanning has correlated well with age reciprocally and with body height positively. and ultrasonography are currently considered the gold standard methods to determine liver size, both techniques using volume as the measure of liver size. Liver volume is a better way to assess liver size as it represents the entire liver, rather than linear measurements in single planes.
