1. What is a Spleen Volume Calculator Ultrasound?

Definition: This calculator estimates spleen volume using ultrasound measurements based on the ellipsoid formula.

Purpose: It helps medical professionals assess spleen size for diagnostic purposes and monitoring of conditions like splenomegaly.

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 the spleen in ultrasound imaging.

3. Importance of Spleen Volume Calculation

Details: Accurate spleen volume measurement helps diagnose and monitor conditions like portal hypertension, hematologic disorders, and infections.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What's a normal spleen volume?
A: Normal spleen volume typically ranges between 100-300 cm³ in adults.

Q2: When is spleen volume measurement needed?
A: When assessing for splenomegaly, monitoring disease progression, or evaluating response to treatment.

Q3: How accurate is this calculation?
A: The ellipsoid formula provides a good estimate but may slightly underestimate true volume compared to volumetric methods.

Q4: What are typical dimensions of a normal spleen?
A: Approximately 11 cm length, 7 cm width, and 4 cm height, but varies with body size.

Q5: Does this replace clinical assessment?
A: No, this is a supplementary tool that should be interpreted in clinical context.
