Objective:
This study aimed to evaluate a new W-Lan-supported ultrasound mobile technology for the diagnosis of vascular peripheral thrombosis.
Material And Methods:
Fifty patients were examined by an experienced reference sonographer using high-end technology and a W-Lan supported device (VScan Air) to evaluate its diagnostic capabilities for peripheral thrombosis.
Results:
Fifty patients were examined (age, 25-88 years; male, n = 27, female n = 23). Thromboses were diagnosed in the neck (n = 1), upper leg (n = 7), lower leg (n = 49), and muscle veins (n = 25). VScan Air technique also allows the diagnosis of circumscribed deep vein thrombosis with a sufficient diagnostic certainty. Moreover, for superficial thrombi that can be well-delineated, a maximum image quality is possible compared to high-end technology.
Conclusion:
The mobile VScan technology opens up new possibilities for near-patient and location-independent imaging in cases of deep vein thrombosis.
