Objective: This study aimed to evaluate the visible vessels of healthy skin using Doppler ultrasound. Methods: Prospective multicenter study using Doppler ultrasound to analyze healthy skin. The color percentage, flow velocity, and maximum vessel diameter were calculated. Results: 943 images from 152 patients were recorded. The most frequently used mode was color Doppler (40.6%), followed by power Doppler (30.4%). Visible vessels were detected in 18.23%; in positive Doppler images, color occupied less than 5%. The malar region exhibited the highest visible vessels. The 22 MHz probe detected smaller vessels with slower flows than the 18 MHz probe. Spectral Doppler showed peak systolic values of less than 10 cm/s and a vessel diameter of less than 1 mm. In most of the participating centers, the operators had less than 10 years of experience in performing skin ultrasound examinations. Sensitivity of the Doppler may vary according to the device. Conclusions: With the used ultrasound equipment, it was uncommon to visualize vessels in healthy skin. When seen, they covered less than 5% of the image with low flow and small size. http://hdl.handle.net/11351/13147 Ecografia Doppler Pell - Imatgeria Vasos sanguinis - Malalties ANALYTICAL, DIAGNOSTIC AND THERAPEUTIC TECHNIQUES, AND EQUIPMENT::Diagnosis::Diagnostic Techniques and Procedures::Diagnostic Imaging::Ultrasonography::Ultrasonography, Doppler::Ultrasonography, Doppler, Duplex::Ultrasonography, Doppler, Color ANATOMY::Integumentary System::Skin Other subheadings::Other subheadings::Other subheadings::/diagnostic imaging DISEASES::Cardiovascular Diseases::Vascular Diseases TÉCNICAS Y EQUIPOS ANALÍTICOS, DIAGNÓSTICOS Y TERAPÉUTICOS::diagnóstico::técnicas y procedimientos diagnósticos::diagnóstico por imagen::ecografía::ecografía Doppler::ecografía Doppler dúplex::ecografía Doppler en color ANATOMÍA::integumento común::piel Otros calificadores::Otros calificadores::Otros calificadores::/diagnóstico por imagen ENFERMEDADES::enfermedades cardiovasculares::enfermedades vasculares Advanced Doppler Ultrasound Insights: A Multicenter Prospective Study on Healthy Skin
