1. What is a Prostate Volume Calculator CT Scan?

Definition: This calculator estimates prostate volume using CT scan measurements based on the ellipsoid formula.

Purpose: It helps medical professionals assess prostate size for diagnostic and treatment planning purposes.

2. How Does the Calculator Work?

The calculator uses the ellipsoid formula:

\[ V = \frac{\pi}{6} \times L \times W \times H \]

Where:

\( V \) — Volume of prostate (cm³)
\( L \) — Length (cm)
\( W \) — Width (cm)
\( H \) — Height (cm)

Explanation: The formula approximates the prostate as an ellipsoid shape, with π/6 (≈0.52) being the ellipsoid correction factor.

3. Importance of Prostate Volume Calculation

Details: Accurate prostate volume measurement is crucial for diagnosing benign prostatic hyperplasia (BPH), planning prostate procedures, and assessing cancer risk.

4. Using the Calculator

Tips: Enter the three orthogonal dimensions (length, width, height) measured from CT scan images in centimeters. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this calculation method?
A: The ellipsoid formula provides a good approximation (within 10-15% of actual volume) for most prostate shapes.

Q2: What's a normal prostate volume range?
A: Typically 20-30 cm³ for young men, may increase to 30-100 cm³ with age due to BPH.

Q3: Can I use this with ultrasound measurements?
A: Yes, the same formula works for TRUS (transrectal ultrasound) measurements.

Q4: How do I measure the dimensions on CT?
A: Measure the longest axis in each dimension on axial, sagittal, and coronal views.

Q5: What's the clinical significance of prostate volume?
A: Larger volumes may indicate BPH, affect PSA density calculations, and influence treatment options.
