“…4 Our experience shows that the use of SMI with high-frequency ultrasound is convenient because it allows better evaluation of slow blood flow than do commonly used methods such as PDI and CDI. 17,18 After the article by Kaya İslamoğlu et al, 21 this work is the second to describe the use of SMI in dermatology. Additional studies of such applications of SMI and high-frequency ultrasound are required to elucidate the use of this new technology to aid diagnostic skin assessment.…”

“…Govind and coworkers found that SMI is more sensitive than color Doppler in demonstrating microvenous reflux in limbs with venous disease and SMI 30 . İslamoğlu and Uysal employed SMI to assess plaques of cicatricial alopecia 31 . To our knowledge, no study has investigated yet the value of SMI in studying skin vascularization.…”

Purpose: Current color-and power-Doppler techniques cannot demonstrate vascularization of the dermis. Aim of this prospective study was to investigate whether the new superb vascular imaging (SMI) technique improves the ultrasound (US) depiction of dermis vessels in healthy volunteers. SMI was compared side-byside to conventional power-Doppler (PD) imaging.Methods: Thirty adult subjects (18 men and 12 women, mean age 45 years old) were evaluated with US at level of five body areas: forehead, forearm, palm, buttock, and thigh. The vascular index (VI) was employed to objectively quantify the difference between SMI and PD imaging in terms of dermis flow amount.Results: Forehead VI was higher for SMI than for PD in 93% of cases, forearm VI was higher for SMI than for PD in 97% of cases, palm VI was higher for SMI than for PD in 87% of cases, buttock VI was higher for SMI than for PD in 100% of cases, thigh VI was higher for SMI than for PD in 100% of cases. SMI-detected vascular signals in 100% of the body areas. PD failed to show any flow signals from the forehead in 23% of cases, forearm in 37% of cases, palm in 33% of cases, buttock in 47% of cases, and thigh in 50% of cases. Conclusion: SMI can demonstrate normal dermis vascularization whereas conven-tional PD cannot. SMI is a sensitive and promising technique in the study of dermis abnormalities, particularly when quantifying the disease activity is important.dermal vessels, dermatology ultrasound, Doppler ultrasound (US), power-Doppler (PD), superb microvascular imaging (SMI) | INTRODUCTIONThe skin is composed by the epidermis and the dermis, the latter consisting for 70% of connective tissue.

Celulite dissecante e foliculite decalvante podem apresentar, em estágios iniciais, quadro clínico semelhante. Este artigo apresenta os achados ecográficos da celulite dissecante que auxiliam no diagnóstico e na abordagem terapêutica. A ecografia não se substitui à observação, tricoscopia e histopatologia mas pode ajudar ao diagnóstico. Em fase activa, observam-se lesões ovóides de bordos relativamente bem definidos, não encapsuladas, com conteúdo hipoecogénico que comunica com a derme através dos bulbos dilatados de folículos pilosos. Permite distinção com foliculite decalvante, com quisto de triquilema (no caso de lesão única ou poucas lesões) e ao permitir avaliar a inflamação quando combinado com Doppler a cores, poderia servir para monitorizar o controlo da inflamação e a resposta terapêutica. Os autores compartilham 2 casos clínicos ilustrativos, sendo apresentada uma revisão da literatura sobre o tema.
