Determination of splenomegaly by coronal oblique length on CT.
Purpose: The aims of this study were (a) to determine whether a coronal oblique length (COL) > 12 cm, which is often used to detect splenomegaly (SM) on ultrasound, can be used as a marker of SM on computed tomography (CT), (b) to compare the diagnostic accuracy of COL with other unidimensional line...

SVol and body mass indexes were calculated for each patient.Results: Of the 1078 patients [male/female = 526/552; 47.57 (mean) ± 19.21 (standard deviation) years], 392 patients had SM. The sensitivity, specificity, positive and negative predictive values of COL > 12 cm for diagnosing SM were 44.6, 95.6, 85.3 and 75.1%, respectively (p < 0.001). SVol correlated with all ULM (p < 0.001). In the non-SM group (n = 686), the mean SVol was 331.7 ± 92.2 cm3 and females had smaller spleens than males (p < 0.001). SVol showed correlation with gender, age and height (p < 0.001).Conclusion: COL > 12 cm is not superior to other ULM for the detection of SM, but it is very successful in determining normal spleens. The unidimensional measurements and volume of the spleen should be calculated by taking gender and body parameters into account for different ethnic populations. Non-contrast-enhanced CT can also be used to detect SM. pubtype: Academic Journal doctype: Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
