Abstract: Our results show that real-time elastography may be useful in differentiating angiomyolipomas from renal cell carcinomas, by use of both elasticity patterns and strain ratios.

“…We had a larger study population than in Tan's study (65 vs. 47). 2 In our study, strain ratio values suggested a benefit method for differentiating renal benign and malignant lesions, with high sensitivity and specificity. Additionally, we found high numbers of true positives and negatives.…”

“…Tan and colleagues found significant differences between strain ratios for angiomyolipomas (AMLs) and renal cell carcinomas (RCCs) (p < 0.01). 2 The aim of our study, therefore, was to prospectively determine the diagnostic efficiency of sonoelastography for differentiating RCCs from AMLs.…”

“…The strain ratio is a semiquantitative measurement of hardness of the lesion with respect to the adjacent soft tissues, where higher ratios point to harder tissues (9). We displayed the adjacent soft tissue in elastographic images and used it for comparison, to achieve a strain ratio.…”

“…[4,15,16] Strain elastography is based on the principle that compression produces strain within the tissue and the amount of strain is lower in stiffer tissue than in softer. [17] Since carcinomas were found to be stiffer than adjacent normal tissues and studies reported that histologically different tumors may display different elasticity patterns according to tissue architecture, [7,10] this technique has been successfully applied to differentiate focal lesions of testis, breast, prostate, pancreas and liver. [14,[18][19][20] Recently, shear wave elastography (SWE) which combines B-mode image with color-coded US generating a quantitative image SWE (kPa) of the tissue stiffness started to be used to exhibit different hardness among different tissue regions in real-time conditions.…”

“…Studies reported that objectively measured tissue stiffness by SE may be used as a diagnostic marker in clinical practice for the differentiation between benign and malignant tissues in various organs. [9][10][11][12] The use of SE for the evaluation of testicular tissues is a new concept. Aigner et al [13] reported that elastography can be used with high sensitivity rate to differentiate benign and malignant testicular lesions.…”
