Determination of a splenic volumetric index by ultrasonic scanning
H. Pietri and M. Boscaini
In a prospective study carried out to determine spleen size by a rapid and
simple ultrasonic method, 45 normal subjects, 20 men and 25 women, average
age 54 +/- 17 years (range 17-78) were studied. The three principal
dimensions of the spleen, breadth, thickness, and height, were obtained
with a compound scan technique; each dimension was measured at its largest
point. The values obtained were multiplied by each other and the product
arbitrarily divided by 27, which is the cube of the three values. This gave
a splenic volumetric index (SVI), which, in 95 per cent of normal subjects,
was between 8 and 34. There were no statistically significant differences
related to age, sex, or morphotype when endomorphs, ectomorphs, and
mesomorphs were examined. This SVI determination, based on standardized
measurements, allows the distinction of normal from abnormal spleens in 10
minutes.
