Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical imaging procedures lack an objective method for determining when to administer enhancing or contrast agents, leading to inefficiencies, additional diagnostic procedures, and potential patient risks due to unnecessary exposure.
Innovation Solution
A processing system that uses machine-learning algorithms to analyze subject data and generate an enhancing or contrast agent advisability indicator, recommending the use or avoidance of these agents based on pathology confidence measures and clinical guidelines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If enhancing or contrast agents are administered to improve image quality, then the accuracy of pathology assessment is improved, but the patient is exposed to unnecessary risks from foreign material introduction
Solution Approach 1:
The system performs preliminary analysis of subject data (demographics, clinical history, previous imaging) before the imaging procedure to predict whether contrast agent administration will be beneficial. This preliminary action allows the system to advise on contrast agent use before the procedure occurs, preventing unnecessary patient exposure while ensuring adequate assessment when needed.
Solution Approach 2:
The system provides feedback to clinicians in the form of an advisability indicator that recommendations based on machine learning analysis of patient data. This feedback mechanism enables informed decision-making about contrast agent administration, balancing the need for accurate pathology assessment with patient safety by highlighting cases where contrast agents are likely to provide diagnostic benefit versus cases where they may cause harm without improving outcomes.
2Ease of operation
If clinicians manually determine when to administer enhancing agents, then clinical judgment can be applied, but time is wasted searching for suitable imaging positions before realizing contrast agents are needed
Solution Approach 1:
The system performs self-service analysis by automatically processing subject data and generating contrast agent advisability indicators without requiring clinician intervention for the prediction itself. This automation handles the time-consuming task of reviewing patient history, demographics, and previous imaging data, allowing clinicians to focus on actual imaging procedures rather than manual assessment of contrast agent suitability.
Solution Approach 2:
The patent replaces the mechanical process of manual clinical assessment with an automated machine learning system. Instead of clinicians manually reviewing patient data and making decisions, the system uses algorithms to process information and generate recommendations, thereby eliminating the time waste associated with manual position searching and contrast agent suitability assessment.
3Measurement precision
If contrast agents are administered to obtain sufficient image quality, then diagnostic accuracy is improved, but additional diagnostic procedures and costs are incurred when images are later found unsuitable
Solution Approach 1:
The system performs preliminary prediction of imaging success before the procedure by analyzing subject data and determining the likelihood that contrast agent administration will produce diagnostically useful images. This preliminary action prevents unnecessary contrast agent administration and subsequent futile diagnostic procedures, thereby improving overall diagnostic efficiency and reducing costs.
Solution Approach 2:
The system provides feedback to clinicians about the predicted effectiveness of contrast agent administration based on patient-specific data. This feedback allows for informed pre-procedure decisions that prevent wasteful additional diagnostic procedures, improving productivity by avoiding time and resources spent on unsuccessful imaging attempts.
4Productivity
If the decision to use enhancing agents is made by image acquirers, then the procedure can be completed quickly, but these acquirers lack expertise in image interpretation and may miss when agents are needed
Solution Approach 1:
The system acts as an intermediary between image acquirers and the complex decision-making process. Instead of requiring acquirers to make informed decisions about contrast agent suitability, the system provides them with an automated advisability indicator that summarizes the machine learning analysis. This intermediary approach maintains quick procedure completion while ensuring accurate assessment decisions through expert-based algorithms rather than relying on the acquirer's interpretive expertise.

AI summary
A system and method for providing an enhancing or contrast agent advisability indicator. Subject data for a subject is processed using an AI-based model to obtain an indication of whether a medical imaging procedure for the subject requires an enhancing or contrast agent. The enhancing or contrast agent advisability indicator is generated with respect to one or more target pathologies assessed in the medical imaging procedure.
