Abstract
Objective: The purpose of this study was to determine the normal splenic volume on computed tomography in Thai adult patients at Siriraj Hospital.
Methods: The width (W), length (L), thickness (T) and splenic volume were obtained from 426 patients who underwent CT for various indications. The relationship between splenic volume and age, gender and body habitus were also examined.
Results: The average splenic volume (S Vol) was 124.1 ± 51.8 cm3, ranging from 27.60 to 430.85 cm3. Correlation between splenic volume and age, height, weight and BMI were significant (age: r = -0.151, p<0.001; height: r = 0.187, p <0.001; weight: r = 0.248, p< 0.001 and BMI: r = 0.159, p<0.05). Splenic volume correlated well with all the linear measurements, especially with the splenic length. The formulae S Vol (in cm3) = 19.6 + 0.5 (LxWxT) and S Vol (in cm3) = -40.3 + 21.4L were derived and can be used to estimate the splenic volume.
Conclusion: Two formulae of splenic measurement indexes were derived with good correlation which can be satisfactorily used in order to estimate splenic volume in routine practice.
