Durante los últimos años, el campo de la ultrasonografía ha tenido importantes avances tecnológicos, llegando a desarrollar equipos que producen imágenes de alta calidad con poder de resolución inferior a 0.1mm y provistos de módulos power Doppler que permiten un detallado estudio morfológico de los tejidos blandos, inclusive la piel. El objetivo de esta viñeta pictórica es demostrar los principales hallazgos ecográficos que se verifican en pacientes con psoriasis utilizando sondas de última generación y técnica power Doppler. En este estudio se tomaron imágenes de 20 pacientes con psoriasis comparándolas con la piel de 10 sujetos sanos. Los resultados muestran una evidencia pictórica de que la ultrasonografía permite un estudio detallado, sea de la uña y de la piel, en pacientes con psoriasis.
Over the last few years, continuous advances have been made in the field of ultrasonography, developing equipments providing high-quality greyscale imaging with an axial resolution power less than 0.1mm and very sensitive power Doppler technique. This fact has opened the way to detailed imaging of the superficial tissues, including the skin. This pictorial essay shows the main sonographic findings obtainable with “last generation” high-frequency transducers and power Doppler technique in patients with psoriatic disease. Sonographic images shown were selected from an image database collected in 20 patients with definite diagnosis of psoriasis and in 10 healthy subjects. The present report provides pictorial evidence that high resolution greyscale ultrasound and power Doppler technique allow for a detailed morphostructural assessment and a sensitive blood flow evaluation at both skin and nail level in patients with psoriatic disease.
