- Original description
The study examines whether a mechanical arm ultrasound system provides diagnostic accuracy comparable to expert-performed full ultrasound for detecting key joint components and whether it can reduce acquisition variability without compromising accuracy, as measured by false-positive and false-negative rates.Read full original descriptionShow less
Can Ultrasound "See" What Clinicians Cannot in Hemophilic Arthropathy? Point-of-Care Ultrasound and Physical Examination Perspectives
The study examines whether a mechanical arm ultrasound system provides diagnostic accuracy comparable to expert-performed full ultrasound for detecting key joint components and whether it can reduce acquisition variability without compromising accuracy, as measured by false-positive and false-negative rates.
Inclusion: Diagnosis of hemophilia A or B or other bleeding disorders; Cooperative patients; Previous study joint bleed (by history) or suspicion of an acute joint bleed.
Exclusion: Co-morbid chronic illnesses causing osteoarticular findings; MRI contraindications.
