What this trial studies

This study aims to gather and create a labeled dataset of ultrasound images and videos from patients undergoing routine scans for suspected deep vein thrombosis (DVT). The collected data will include patient demographics, medical history, and details about the ultrasound equipment used. The primary goal is to anonymize this dataset for research purposes, specifically to train an AI model for automated DVT detection. By improving the accuracy of DVT diagnosis, the study seeks to enhance patient safety and outcomes related to this serious condition.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older who are suspected of having DVT and require an ultrasound scan as part of their clinical assessment.

Not a fit: Patients who are not suitable for a standard ultrasound scan or who have conditions that may interrupt the examination will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more accurate and timely detection of deep vein thrombosis, potentially reducing the risk of serious complications like pulmonary embolism.

How similar studies have performed: Other studies have shown promise in using AI for medical imaging, suggesting that this approach could be effective in improving DVT detection.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Age ≥18 years.
* The participant has the capacity to consent, and consent is obtained prior to any study-specific procedures.
* The conventional diagnostic DVT algorithm indicates that an ultrasound is needed, or the patient has been referred for a scan on suspicion of DVT.

Exclusion Criteria:

* Patients with a known condition or reason that may potentially result in interrupting or stopping the ultrasound examination before its completion.
* Patients considered by their treating physician or the ultrasound operator as non-suitable for a standard ultrasound scan.
* Patients who have not signed the informed consent.
