“…SWE is a newer elastic imaging technology which is a newer variant of RTE [40]. Different from earlier technology, it uses shearwave and does not need to compress and decompress the tissues to generate strain [41]. The shear waves are generated using acoustic radiation force automatically induced by the supersonic speed.…”

Background: Chronic liver disease (CLD) is an important cause of morbidity and mortality and can lead to hepatic fibrosis. This study was conducted to evaluate the diagnostic value of real-time shear wave elastography (SWE) in the assessment of hepatic fibrosis. Methods: A systematic search of databases was performed for publications on SWE during the period between 2010 and 2017. The identified studies were analyzed using Meta-disc 1.4 software to integrate and analyze the data. Results: Eleven studies comprising 1560 patients were included for analysis. The pooled sensitivity, specificity and diagnostic odds ratio were 0.85 (95% CI: 0.82-0.87), 0.79 (95% CI: 0.76-0.82) and 30.81 (95% CI: 16.55-57.34), respectively for patients with a Metavir-score of ≥ F2; 0.87 (95% CI: 0.84-0.91), 0.84 (95% CI: 0.82-0.87), 41.45 (95% CI:18.25-94.45), respectively for patients with ≥ F3; 0.88(95% CI: 0.83-0.91), 0.91 (95% CI: 0.89-0.92), 67.18 (95% CI:30.02-150.31), respectively for patients with ≥ F4. The areas under the receiver operating characteristic curve of the three groups were 0.9147, 0.9223 and 0.9520, respectively. Conclusions: Our work demonstrates that SWE is highly accurate for detecting and staging hepatic fibrosis.

“…However, US has a role in differentiating delayed presentation of testicular torsion from other pathologies. By comparing the pathological evaluation of the surgical specimen with pre-operative testicular torsion at different time points and different degrees of torsion, Herek et al [30] showed that testicular tissue stiffness gradually increased from 360° to 720° of torsion and became softer at 1,080°, where necrosis occurred and damage to the testes became irreversible. They also showed that the contralateral testis was also affected and presented increased tissue stiffness.…”

Elastography of focal testicular lesions: current concepts and utility

2019

As a relatively new sonographic technique, tissue elastography has emerged as a qualitative and potentially quantitative adjunctive tool to provide additional information on tissue stiffness, aiming to further improve diagnostic confidence in discriminating benign from malignant focal testicular lesions. The purpose of this review is to provide an overview of the elastography techniques used to assess focal testicular lesions and their typical appearance on tissue elastography.

Objectives To compare elastography measurements in men with normal testicular tissue, testicular microlithiasis and testicular cancer. Methods A total of 248 consecutive patients were included. All men provided written informed consent. Testicular stiffness was assessed using shear wave elastography (SWE). Three SWE velocity measurements were assessed in each testicle. The patients were divided into three groups; men with normal testicular tissue (n=130), men with testicular microlithiasis (n=99) and men with testicular cancer (n=19). Results We found a higher mean velocity in the group of patients with testicular cancer (1.92 m/s (95% CI 1.82–2.03)) compared to both the group with normal tissue (0.76 m/s (95% CI: 0.75–0.78)) (p<0.001) and the group with testicular microlithiasis 0.79 m/s (95% CI: 0.77–0.81) (p<0.001). Conclusion The presence of testicular microlithiasis increased stiffness slightly, but within the range of variation in normal testicles. Increased stiffness may indicate testicular malignancy in testicular lesions. Ultrasound elastography could be a very useful tool when investigating scrotum.

Role of Strain Elastography in the Evaluation of Testicular Torsion

Abstract: Our results show that real-time strain elastography can be a complementary method in the evaluation of testicular tissue in testicular torsion and can guide surgeons in their surgical approach.
