More about: Rotterdam CT

What it calculates

The “Rotterdam CT” calculator computes Rotterdam score in points from 4 parameters: basal cisterns (0 normal, 1 compressed, 2 absent), midline shift (mm), epidural hematoma (1 = yes), intraventricular or traumatic subarachnoid hemorrhage (1 = yes).

Used by professionals and patients to assess health metrics, dosages, and risks.

Example calculation

With parameters Basal cisterns (0 normal, 1 compressed, 2 absent) = 0, Midline shift = 0 mm, Epidural hematoma (1 = yes) = 0, Intraventricular or traumatic subarachnoid hemorrhage (1 = yes) = 1 the result is 3 points (Data from Maas 2005, patients with moderate to severe TBI).

How to use

  1. Enter basal cisterns (0 normal, 1 compressed, 2 absent), midline shift, epidural hematoma (1 = yes) and intraventricular or traumatic subarachnoid hemorrhage (1 = yes) — each field above is adjustable with a slider.
  2. Rotterdam score (points) is calculated automatically as you type.
  3. Check the worked example below to see the formula applied to real numbers.
  4. Copy the result or bookmark this calculator.

FAQ

How is BMI calculated?
BMI = weight (kg) / height (m)². Example: 70 kg / (1.75 m)² = 22.9. The WHO normal range is 18.5–24.9; below that is underweight, 25–29.9 is overweight, and 30+ is obese.
Is BMI accurate for everyone?
No. BMI does not distinguish muscle from fat, so athletes may show a high BMI with low body fat. It is also less reliable for teenagers, pregnant people, older adults, and very tall or short individuals.
What are the BMI categories?
Underweight: below 18.5. Normal: 18.5–24.9. Overweight: 25–29.9. Obese class I: 30–34.9; class II: 35–39.9; class III: 40+.
What is a better measure than BMI?
Body fat percentage, waist-to-height ratio (aim for under 0.5), and waist circumference give a clearer picture of health than BMI alone.
