1. What is Normal Adult Spleen Volume?

Definition: This calculator estimates the volume of an adult spleen using ellipsoid approximation based on length, width, and height measurements.

Purpose: It helps medical professionals assess spleen size, which is important for diagnosing conditions like splenomegaly or spleen atrophy.

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 approximates the spleen as an ellipsoid, using the standard volume calculation for this shape.

3. Importance of Spleen Volume Measurement

Details: Normal adult spleen volume typically ranges between 100-250 cm³. Volume assessment helps detect abnormalities and monitor disease progression.

4. Using the Calculator

Tips: Enter the length, width, and height measurements in centimeters from ultrasound or CT imaging. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's considered a normal spleen volume?
A: Typically 100-250 cm³ in healthy adults, though this can vary slightly with body size.

Q2: When is spleen volume measurement important?
A: For evaluating splenomegaly, monitoring hematologic disorders, or assessing trauma cases.

Q3: How accurate is this estimation?
A: The ellipsoid formula provides a good approximation but may differ slightly from volumetric measurements.

Q4: What imaging modalities can provide these measurements?
A: Ultrasound, CT, or MRI can all provide the necessary dimensional measurements.

Q5: Does age affect normal spleen volume?
A: Yes, spleen size tends to decrease slightly with age after reaching adulthood.
