1. What is a Spleen Volume Calculator?

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

Purpose: It helps radiologists and clinicians assess spleen size, with normal range typically between 100-250 cm³.

2. How Does the Calculator Work?

The calculator uses the ellipsoid formula:

Where:

• \( V \) — Volume of spleen (cm³)
• \( L \) — Maximum length (cm)
• \( W \) — Maximum width (cm)
• \( H \) — Maximum height (cm)

Explanation: The formula approximates the spleen as an ellipsoid shape, which is the standard method for radiological spleen volume estimation.

3. Importance of Spleen Volume Calculation

Details: Accurate spleen volume measurement helps diagnose splenomegaly (enlarged spleen) or splenic atrophy, which can indicate various pathological conditions.

4. Using the Calculator

Tips: Enter measurements in centimeters from imaging studies (CT, MRI, or ultrasound). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is the normal spleen volume range?
A: Typically 100-250 cm³ in healthy adults, but varies with body size and age.

Q2: How accurate is this estimation method?
A: The ellipsoid formula provides good approximation (±10%) compared to more complex methods.

Q3: When is spleen considered enlarged?
A: Generally when volume exceeds 300 cm³ or craniocaudal length >12 cm on imaging.

Q4: What imaging planes are used for measurements?
A: Typically axial (width/height) and coronal/sagittal (length) planes.

Q5: Does this work for pediatric patients?
A: Yes, but normal ranges are age-dependent in children.
