“…1). This is known as a 3-ring structure [7]. Mean shear wave velocities of 0.76 m/sec (95% confidence interval, 0.75 to 0.78 m/sec) from 130 normal testicles and 1.92 m/sec in 19 patients with testicular cancer have been reported by Pedersen et al [8] and Marcon et al [9], respectively, both using virtual touch tissue imaging quantification (VTIQ; Siemens Medical Solutions, Mountain View, CA, USA).…”

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.

“…They found that stiffness increased and volume decreased as age increased. Following this study, testicular elastography was used to examine various types of testicular focal lesions, torsion or segmental infarctions [13,[18][19][20][21][22][23][24]. These studies demonstrated the feasibility of elastography for evaluating elasticity in normal and diseased testes.…”

Aims: To evaluate the differences and changes of testicular volume and elasticity in normal (NL) testes and undescended testes (UDTs) of children using shear wave elastography (SWE).Materials and methods: Testicular ultrasound images from children younger than 60 months old were retrospectively reviewed. Testicular volumes and elasticities were compared between the UDT group and NL group. In patients with unilateral UDT (uUDT), we also compared the values between uUDT and contralateral grossly normal (CGN) testis groups.Results: There were 25 UDTs including 4 bilateral in the UDT groupand 54 normal testes in the NL group. While testicular volume was significantly smaller in UDT (vs. NL) and uUDT (vs. CGN) groups, the elasticity was not different. Testicular volume was positively correlated with age in both NL (r=0.474) and CGN (r=0.729) groups (p<0.001), while there was no correlation in the UDT group. Testicular stiffness showed negative correlation with age in the NL group (r=-0.390, p=0.004) and positive correlation in the UDT group (r=0.426, p=0.034).Conclusions: Instead of increasing volume and decreasing stiffness of normal testes during development of the early 60 months, UDTsexhibited smaller volume and increasing stiffness. The CGN testes of uUDT patients showed increasing volume without stiffness change.

Ultrasound (US) can be used to evaluate the brain structure and nervous system damage. Patients with neurologic symptoms need rapid, noninvasive imaging with high spatial resolution and tissue contrast. Magnetic resonance imaging is currently the most sensitive and specific imaging method for evaluating neuropathologic conditions. This approach does present some challenges, such as the need to transport patients who may be seriously ill to the magnetic resonance imaging suite and the need for patients to remain for a considerable time. Cranial US provides a very valuable imaging method for clinicians, which can make a rapid diagnosis and evaluation without ionizing radiation. The main disadvantage of cranial US is its low sensitivity and specificity for subtle/early lesions. In recent years, with the rapid development of anatomic and functional US technology, the practicability of US diagnosis and intervention has been greatly improved. Ultrasound elastography may have the potential to improve the sensitivity and specificity of various cranial nerve conditions. Ultrasound elastography has received considerable critical attention, and an increasing number of studies have recognized its critical role in evaluating brain diseases. At present, US elastography has been applied to the evaluation of traumatic brain injury, ischemic stroke, intraoperative brain tumors, and hypoxic ischemic encephalopathy. The latest animal experiments and human clinical trial developments in the applications of US elastography for brain diseases are summarized in this review.

Application of Quasistatic Ultrasound Elastography for Examination of Scrotal Lesions

Abstract: Quasistatic elastography can reflect the relative stiffness of the testis and its surrounding tissues, thus providing a novel, reliable, convenient, and noninvasive method for clinical detection of testicular stiffness and related pathologic changes.
