“…The values measured tend to deviate greatly because of the free-hand technique. Moreover, skin and subcutaneous tissue strains can be affected by other factors such as age (Osanai et al 2011). In consideration of the aforementioned problems and confounding factors, these measurements should be interpreted cautiously at present.…”

“…The various solitary skin lesions were imaged in B mode (2 Dimensional image) without colour Doppler at 14 MHz because it was the maximum frequency commercially available and FDA approved for human use by the vendor in the United States when this study was performed, and it is within the range previously reported as acceptable for the task. 5,33,34 At this frequency, the maximum depth of penetration is 40 mm. In this study, the frame of view for the ultrasound transducer was kept between 7.5 and 10 mm.…”

“…[28][29][30][31] High-frequency ultrasound also offers an intriguing analog to traditional skin palpation; it can provide information about the stiffness of a lesion at and below the skin surface, using the functional image processing technique known as ultrasound elastography (USE). [32][33][34][35][36][37] In strain elastography, a single relatively small compression made by the transducer allows determination of the rate of change in displacement of tissue as a function of distance from the transducer (strain). The strain value is an indirect measurement of elasticity.…”

Objective: To evaluate the feasibility of high-frequency ultrasound and ultrasound elastography (USE) in discriminating benign from malignant skin lesions in a prospective cohort study and to introduce the use of a "strain ratio" for evaluation of skin lesions. Methods: A commercial ultrasound system with a 14-MHz transducer was used to visualize skin lesions requiring biopsy on clinical evaluation. Anatomic ultrasound and USE imaging of the skin lesions was performed using 2-to 4-mm gel stand-off pads. A region of interest was manually selected over the area of each lesion with the lowest strain. The concept of a strain ratio of the compressibility of the normal skin at the corresponding layer to that of the least compressible region of a lesion in question was created and applied. This ratio was subsequently correlated with blind histopathological evaluation for malignancy. Results: 55 patients were included in the study with a total of 67 lesions evaluated. 29 lesions were malignant and 38 benign. All malignant lesions had strain ratios $3.9. All benign lesions had strain ratios #3.0. A diagnostic value between 3.0 and 3.9 would result in 100% sensitivity and specificity in the characterization of these lesions as malignant.Conclusion: This pilot study demonstrated that USE plus strain ratio appears to be a promising modality in providing diagnostic determination between cancerous and benign primary solitary skin lesions prior to biopsy. Advances in knowledge: This is the first reported study applying an original mathematical elastographic ratio, or strain ratio, to evaluate primary solitary skin lesions.

“…To the best of our knowledge, except for a few studies [13,17,20,21], elastographic parameters of normal skin have not been studied to date, and no published reference values for skin strain have been identified thus far. Moreover, most previous cutaneous elastography studies were relatively small observational studies or analyses of case series.…”

“…The dermis is characterized by higher strain than subcutaneous tissue [21]. Furthermore, the latter is not homogeneous in terms of its elastographic characteristics, due to the presence of stiffer connective tissue septa, and more elastic adipose tissue lobes, blood vessels and nerve fibers [21].…”

A b s t r a c tThe aim of this review article is to discuss the role of ultrasonographic elastography, a technique used to quantify tissue stiffness, in the evaluation of normal and pathological skin. A growing body of evidence suggests that elastography may be used for the diagnosis and monitoring of skin pathologies, in particular tumors, and fibrotic and sclerotic processes. Our knowledge about the elastographic parameters of normal skin is sparse, which together with the lack of reference values for cutaneous stiffness constitutes a serious limitation to the use of elastography in some medical disciplines, including aesthetic medicine.
