1. What is Normal Spleen Volume Calculator?

Definition: This calculator estimates normal spleen volume in milliliters (1 cm³ = 1 ml) using the prolate ellipsoid formula.

Purpose: It helps medical professionals assess spleen size, with normal range typically between 100-250 ml in healthy adults.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ V = \frac{\pi}{6} \times L \times W \times H \]

Where:

\( V \) — Volume of spleen (ml)
\( L \) — Maximum length (cm)
\( W \) — Maximum width (cm)
\( H \) — Maximum height (cm)

Explanation: The formula approximates the spleen as a prolate ellipsoid, where π/6 (~0.5236) is the shape factor.

3. Importance of Spleen Volume Measurement

Details: Spleen volume assessment helps diagnose conditions like splenomegaly (enlarged spleen) or splenic atrophy.

4. Using the Calculator

Tips: Enter maximum dimensions from ultrasound, CT, or MRI measurements in centimeters. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's the normal spleen volume range?
A: Typically 100-250 ml in healthy adults, but varies with body size and age.

Q2: How accurate is this estimation?
A: It provides a good approximation (within 10-15% of actual volume) when proper measurements are taken.

Q3: When is spleen volume measurement needed?
A: For monitoring conditions like portal hypertension, hematologic disorders, or post-transplant evaluations.

Q4: How does spleen volume change with age?
A: Spleen volume increases during childhood, peaks in young adulthood, and may decrease slightly with advanced age.

Q5: What imaging modalities can provide these measurements?
A: Ultrasound, CT, and MRI can all provide the necessary dimensional measurements.
