1. What is Spleen Volume Calculation?

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

Purpose: It helps radiologists and clinicians assess spleen size for detecting splenomegaly or other abnormalities.

2. How Does the Calculator Work?

The calculator uses the 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 Measurement

Details: Normal spleen volume ranges between 100-250 cm³ in adults. Volume >500 cm³ typically indicates splenomegaly.

4. Using the Calculator

Tips: Enter measurements obtained from ultrasound, CT, or MRI scans. 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: How accurate is this calculation?
A: The ellipsoid formula has about 90% correlation with actual spleen volume.

Q3: When should I suspect splenomegaly?
A: When volume exceeds 500 cm³ or length >13 cm in adults.

Q4: Does spleen size vary with age?
A: Yes, spleen size increases during childhood and decreases slightly in elderly.

Q5: What imaging modality is best for measurement?
A: Ultrasound is most common, but CT or MRI provide more precise measurements.
