Clinical Scorecard: Comparison of Automated and Manual Approaches to Cardiac MRI Planning: A Prospective Assessment of Reliability and Scan Duration at a Single Center
At a Glance
Category
Detail
Condition
Cardiac magnetic resonance imaging (CMR) planning and execution
Key Mechanisms
Automated AI-based software for CMR planning automates cardiac plane selection, parameter adjustment, and sequence acquisition to reduce human error and scan time
Target Population
Adult patients scheduled for non-stress CMR without implantable cardiac devices or targeted sequences outside the evaluated protocol
Care Setting
Single-center clinical MRI scanner setting with trained MR technologists and radiologist supervision
Key Highlights
Manual CMR planning is complex, requiring extensive technologist training and involving many manual steps prone to errors and prolonged scan times.
Automated AI-driven CMR planning software can fully automate acquisition steps including positioning, parameter adjustment, and inversion time selection, potentially reducing errors and scan duration.
A prospective randomized study alternating weekly between automated and manual planning assessed reliability (error rates) and efficiency (scan times) in a clinical setting.
Guideline-Based Recommendations
Diagnosis
Use standardized CMR protocols with consistent cardiac plane acquisition to ensure reliable diagnostic imaging.
Exclude patients with implantable cardiac devices or those requiring targeted sequences not covered by the protocol.
Management
Implement AI-based automated planning software to streamline CMR acquisition steps and reduce operator-dependent variability.
Allow operator intervention only for safety checks or fine-tuning parameters as needed.
Monitoring & Follow-up
Record clinical indication, patient compliance, heart rate and rhythm, technologist experience, and breathing strategy to monitor factors influencing scan quality.
Supervise examinations by experienced radiologists to ensure protocol adherence and image quality.
Risks
Planning errors and inter-operator variability can prolong scan times and reduce image quality.
Incorrect breath-hold capacity assessment or early termination can lead to incomplete or suboptimal studies.
Patient & Prescribing Data
Consecutive adult patients undergoing non-stress CMR without contraindications or exclusions as per protocol
Automated CMR planning software can reduce scan time and errors compared to manual planning, improving patient comfort and examination consistency.
Clinical Best Practices
Train MR technologists extensively in CMR planning and execution to minimize errors during manual procedures.
Use automated planning software to reduce cognitive load and error potential during CMR acquisition.
Randomize or alternate between automated and manual planning approaches to evaluate and optimize workflow efficiency.
Choose breathing strategy (free breathing or breath-hold) based on patient capacity to optimize image quality.
Supervise CMR examinations with experienced radiologists to maintain diagnostic standards.
