What is Advanced ICH Volume Analysis?
The Advanced ICH Volume Calculator is a comprehensive medical tool designed to accurately measure and assess intracerebral hemorrhage (ICH) volume using multiple validated calculation methods. This sophisticated calculator combines the widely-used ABC/2 formula with advanced techniques including ABC/3 methodology, planimetry estimation, and shape factor optimization to provide precise volume measurements critical for emergency medicine and neurocritical care decisions.
Beyond simple volume calculation, this tool integrates the validated ICH Score assessment system, providing 30-day mortality predictions, functional outcome analysis, and evidence-based clinical decision support. Healthcare professionals rely on accurate ICH volume measurements to determine surgical intervention thresholds, establish treatment priorities, and guide prognostic counseling for patients and families.

๐ Step-by-Step Usage Guide
Phase 1: CT Measurement Input
- 1Measure Length A: Identify the largest diameter of the hemorrhage on the CT slice with the greatest area
- 2Measure Width B: Measure the width perpendicular to Length A on the same CT slice
- 3Count Slices: Count the total number of CT slices containing visible hemorrhage
- 4Enter Slice Thickness: Input the CT scan slice thickness (typically 5mm or 10mm)
Phase 2: Clinical Assessment
- 5Select Shape Type: Choose hemorrhage morphology (ellipsoid, irregular, or round)
- 6Enter GCS Score: Input the current Glasgow Coma Scale (3-15)
- 7Complete ICH Score: Assess intraventricular hemorrhage and infratentorial location
- 8Clinical Context: Add relevant clinical information and patient demographics
๐ก Pro Tips for Accurate Measurements
- โข Use the same windowing settings for consistent measurements across slices
- โข Measure on the slice with the largest hemorrhage area for Length A and Width B
- โข Include any areas of mixed density within the hemorrhage boundary
- โข For irregular shapes, consider using the ABC/3 method for better accuracy
- โข Double-check slice count by scrolling through the entire CT dataset

ICH Volume Calculation Formulas Explained
Our calculator employs multiple scientifically validated formulas for accurate intracerebral hemorrhage volume calculation. Understanding these mathematical approaches helps healthcare professionals make informed decisions about the most appropriate calculation method for each clinical scenario.
๐ Core ICH Volume Calculation Methods
ABC/2 Formula (Standard Method)
Where:
- A = Maximum length (largest diameter on axial CT slice)
- B = Maximum width (perpendicular to A on same slice)
- C = Approximate height (number of slices ร slice thickness)
Most widely used method for ellipsoid-shaped hemorrhages with 95% accuracy for volumes >30ml
ABC/3 Formula (Irregular Shapes)
Application:
- Used for irregular or non-ellipsoid hemorrhage shapes
- Better accuracy for complex morphology ICH
- Measurements identical to ABC/2 but different divisor
Preferred method for irregular hemorrhages with improved accuracy over ABC/2
Planimetry Method (Gold Standard)
Process:
- Trace hemorrhage outline on each CT slice
- Calculate area for each slice
- Sum all areas and multiply by slice thickness
Most accurate method but time-intensive; used as reference standard for validation
ICH Score Calculation
Scoring Components:
- GCS 3-4 = 2 points, GCS 5-12 = 1 point, GCS 13-15 = 0 points
- Age โฅ80 = 1 point, Age <80 = 0 points
- ICH volume โฅ30ml = 1 point, Volume <30ml = 0 points
- Intraventricular hemorrhage = 1 point, No IVH = 0 points
- Infratentorial location = 1 point, Supratentorial = 0 points
Validated prognostic tool predicting 30-day mortality with high accuracy
30-Day Mortality Risk Calculation
Risk Stratification:
- ICH Score 0: ~0% mortality risk
- ICH Score 1: ~13% mortality risk
- ICH Score 2: ~26% mortality risk
- ICH Score 3: ~72% mortality risk
- ICH Score 4: ~97% mortality risk
- ICH Score 5-6: ~100% mortality risk
