## What is IUS?

The first Intestinal Ultrasound IBD scores calculator now available!

This application is not a medical device and is intended solely as a calculation tool for medical professionals to assist in the assessment of Intestinal Ultrasound (IUS) in Inflammatory Bowel Diseases (IBD) parameters using scientifically validated scoring systems. 
	•	The application does not provide medical diagnoses, treatment recommendations, or clinical decision-making support for patients.
	•	It does not collect or store clinical data but only processes ultrasound measurements entered by the user.
	•	The results generated by the application are intended exclusively for healthcare professionals and have no direct utility for patients.

Included scores: 
• IBUS-SAS International Bowel Ultrasound Segmental Activity Score 
• BUSS Bowel Ultrasound Score
• SUS-CD Simple Ultrasound Crohn's disease Score 
• Simple-US Score 
• MUC Milan Ultrasound Criteria Score

This tool is designed to be used in conjunction with medical expertise and clinical judgment. It does not replace professional evaluation, medical consultation, or patient-specific clinical assessment.

By using this application, users acknowledge that it serves as a reference tool for physicians and should not be used for independent clinical decision-making or as a substitute for professional medical care.
