High Resolution Ultrasonography in Benign Lesions of Skin and Subcutaneous Tissue

Abstract

Purpose. Assessment the feasibility of using high-resolution linear ultrasonic transducers and diagnostic value of sonoelastography in the study of benign lesions of skin and subcutaneous tissue. Materials and methods. A total of 50 patients range 28-80 years with benign skin and subcutaneous lesions were evaluated using B-mode ultrasonography, pulsed wave Doppler, color Doppler, power Doppler and semiquantitative sonoelastography. Results. Developed a method, evaluated the ultrasonic and sonoelastographic criteria of non-invasive differential diagnosis common in outpatient volume benign skin and subcutaneous disorders. The presence of hyperechoic entry echo with acoustic shadow is statistically significant sign of the differential diagnosis between keratomas and nevi. Using a distinct strain ratio for the most rigid zone of the benign lesion statistically significant allows to differentiate nevi and dermatofibroma. Conclusion. High resolution ultrasound transducers using frequencies in the range 12-17 MHz enables detailed imaging of benign lesions of skin and subcutaneous tissue. Sonoelastography is inexpensive and promising technique to improve the differential diagnosis of cutaneous and subcutaneous benign lesions.
