GUTIERREZ, Marwin; RESTREPO, Juan Pablo; FILIPPUCCI, Emilio  and  GRASSI, Walter. The use of high-frequency ultrasound in the study of skin and psoriatic nail. Rev.Colomb.Reumatol. [online]. 2009, vol.16, n.4, pp.332-335. ISSN 0121-8123.

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 0.1 mm 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.

Keywords : ultrasonography; power Doppler; high frequency; skin; nail; psoriasis; onychopathy.
