ICH Intracranial Hemorrhage Calculator

Tool Introduction

The ICH Intracranial Hemorrhage Calculator is an online tool specifically designed for medical professionals, aiming to quickly estimate the volume of intracranial hemorrhage (bleeding volume) by inputting the length, width, and height of the hematoma. It assists doctors in preliminary assessment of brain hemorrhage patients' conditions during emergencies or routine work, providing quantitative reference for clinical diagnosis, treatment plan formulation, and prognosis judgment. This calculator is based on recognized estimation methods, effectively simplifying manual calculation processes and improving work efficiency.

How to Use

1. In the “Hematoma Length” input box, enter the maximum length value of the hematoma based on CT or MRI imaging measurement results.
2. In the “Hematoma Width” input box, enter the maximum width value of the hematoma.
3. In the “Height” input box, enter the maximum height value of the hematoma.
4. After completing the input, the tool will automatically display or show the estimated “Intracranial Hemorrhage Volume” by clicking the calculate button (depending on the actual interface design).

Input Parameter Requirements:

• Hematoma Length (length): Required, numerical type, unit is “centimeter (cm)”, value range is 0.1 to 50.
• Hematoma Width (width): Required, numerical type, unit is “centimeter (cm)”, value range is 0.1 to 50.
• Height (height): Required, numerical type, unit is “centimeter (cm)”, value range is 0.1 to 50.

Output Result Format:

The tool will display the “Intracranial Hemorrhage Volume” in a list format, with the unit “milliliter (mL)”.

Frequently Asked Questions

• Q: What is the calculation principle for ICH intracranial hemorrhage volume?
• A: This calculator primarily uses the ABC/2 (or XYZ/2) formula for estimation. A, B, and C represent the maximum length, width, and height of the hematoma in mutually perpendicular directions, respectively. This method is widely used for rapid estimation of supratentorial intraparenchymal hemorrhage volume and has good practical utility.
• Q: What are the units for the input parameters?
• A: The units for all input parameters (hematoma length, width, height) are “centimeters (cm)”. Please ensure consistent units during input to avoid calculation errors due to unit mismatch.
• Q: What is the unit for the output result?
• A: The output “Intracranial Hemorrhage Volume” unit is “milliliters (mL)”.
• Q: Is this calculator applicable to all types of intracranial hemorrhage?
• A: This tool is primarily suitable for estimating the hematoma volume of supratentorial intraparenchymal hemorrhage. For intraventricular hemorrhage, subarachnoid hemorrhage, or extremely irregular hemorrhage morphology, the calculation results may have some deviation, and it is recommended to make a comprehensive judgment in conjunction with actual clinical conditions.

Important Notes

• Please ensure that the entered hematoma length, width, and height data are accurate. These data typically come from CT or MRI imaging measurements. The precision of the data directly affects the accuracy of the calculation results.
• All input fields are required and must be valid numbers, with a value range between 0.1 and 50. Entering values outside this range or non-numeric characters may lead to calculation errors or inability to calculate.
• The results of this calculator are only estimates, intended to provide auxiliary reference for clinical decision-making, and cannot replace professional medical diagnosis and comprehensive clinical evaluation.
• When performing imaging measurements, try to select the maximum diameter of the hematoma and ensure that the three diameters are mutually perpendicular to maximize the accuracy of the estimation.
• For hematomas with extremely irregular morphology, such as multifocal hemorrhage or hemorrhage adjacent to the ventricles, the ABC/2 estimation method may have certain limitations. It is recommended to combine other imaging evaluation methods.
