1. What is Normal Spleen Measurement?

Definition: This calculator estimates the volume of a normal spleen using ellipsoid formula based on length, width, and height measurements.

Purpose: It helps medical professionals assess spleen size for diagnostic purposes and monitor changes over time.

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 (cm³)
\( L \) — Length (cm)
\( W \) — Width (cm)
\( H \) — Height (cm)

Explanation: The formula calculates the volume of an ellipsoid, which approximates the shape of a normal spleen.

3. Importance of Spleen Volume Calculation

Details: Measuring spleen volume helps detect splenomegaly (enlarged spleen) or atrophy, which can indicate various medical conditions.

4. Using the Calculator

Tips: Enter the spleen dimensions in centimeters as measured by ultrasound, CT, or MRI. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What are normal spleen dimensions?
A: Typically 10-12 cm in length, 7-8 cm in width, and 3-4 cm in height.

Q2: What's a normal spleen volume range?
A: Normal volume ranges from 150-350 cm³ in adults.

Q3: When is spleen volume measurement most useful?
A: For monitoring conditions like portal hypertension, hematologic disorders, or assessing response to treatment.

Q4: How accurate is this calculation?
A: The ellipsoid formula provides a good estimate but may vary slightly from actual volume.

Q5: Should I use this for pediatric patients?
A: No, normal spleen size varies significantly with age in children.
