“…In both cases, their stable, small testicular lesion was associated with distant metastasis (one pulmonary and one retroperitoneal) diagnosed at follow-up, confirming that a total body scan is necessary in patients for whom a surveillance strategy is adopted (24). A further improvement of the reported accuracy could also potentially be obtained by integrating contrast-enhanced US with other techniques such as elastosonography and MR imaging (25,31,32).…”

).q RSNA, 2014 Purpose:To evaluate the diagnostic accuracy of unenhanced and quantitative contrast-enhanced ultrasonography (US) in the differential diagnosis of small nonpalpable testicular lesions. Materials andMethods:The local review board approved the protocol, and all patients provided written informed consent. One hundred fifteen patients (median age, 34 years; age range, 14-61 years) with nonpalpable testicular lesions were consecutively enrolled between 2006 and 2012 and underwent unenhanced scrotal US, contrast-enhanced US, surgical enucleation, and at least 18 months of follow-up. Clinical and histologic features were recorded, and qualitative and quantitative analysis of contrast-enhanced US time-intensity curves were performed. Logistic regression analysis was performed to explore features of malignancy. Receiver operating characteristic (ROC) curves were developed for cumulative unenhanced and contrast-enhanced US scores. Results:All lesions were 1.5 cm or smaller. Forty-four of the 115 patients (38%) had malignant tumors, 42 had benign tumors (37%), and 29 (25%) had nonneoplastic lesions. Conclusion:Benign testicular tumors are frequent incidental findings. Quantitative scrotal contrast-enhanced US is a noninvasive diagnostic tool that could improve the differential diagnosis and individualized management of small testicular lesions.q RSNA, 2014

Prospective evaluation of Quasistatic Ultrasound Elastography (USE) compared with Baseline US for parotid gland lesions: preliminary results of elasticity contrast index (ECI) evaluation

et al. 2017

Aims: To assess the diagnostic value of elasticity contrast index (ECI) elastography, in comparison with conventional ultrasound for the differentiation of benign and malignant parotid lesions. Material and methods: Sixty-three consecutive patients with parotid gland tumors, treated surgically at a single tertiary center were enrolled. Ultrasound evaluation consisted of B-mode, color-Doppler and quasistatic ultrasound elastography (USE), conducted with the ECI technique. For each lesion the echogenicity, margins, vascularization, and capsulation were considered to determine benign or malignant lesions. Histology was considered the gold standard. Results: Using conventional parameters, the observer suggested malignant lesions in 20 cases and benign lesions in 43 cases (accuracy: 61.8%). ECI>3.5 alone was the most accurate parameter (accuracy: 90.5%), with sensitivity of 93.7% and specificity of 89.4%. However, when combined with the other US criteria, no statistically significant diagnostic accuracy improvement was achieved. Conclusions: Our results show that USE with ECI index measurement can help to discriminate preoperatively benign from malignant lesions, with the exception of pleomorphic adenoma which is stiff. We suggest that USE can be used as an additional tool to conventional US evaluation of salivary gland lesions.

“…TRUS elastography has been developed with the rationale that prostate cancer is stiffer than normal prostate tissue. Evidence from the literature suggests that TRUS elastography is helpful in the following aspects: (i) characterize abnormal areas detected using other imaging modalities, (ii) detect new lesions not seen with previous modalities, and (iii) target suspicious lesions on biopsy [10]. TRUS elastography in the prostate is mainly based on two approaches: strain elastography, which was introduced more than a decade ago, and the more recently developed shear wave elastography (SWE).…”
