Aim: To evaluate the clinical value of real-time shear wave elastography (SWE) in differential diagnosis of testicular torsion and acute orchiditis.Material and methods: During a 3-year period, 14 cases of testicular torsion and 16 cases of acute orchiditis met the inclusion criteria. Young’s modulus maximum hardness (Emax) of testicular capsule region, middle testicular parenchyma, warped spermatic segment or inferior spermatic segment was measured in each group. SWE “stiff ring sign” of testis refers to the appearance of a red ring in the testicular capsule area and “stiff knot sign” of spermatic cord refers to the appearance of a red knot in the lower segment of the spermatic cord.Results: Emax value of the testicular capsule in the torsion group was higher than in the acute inflammation group (138.76±58.27 vs 16.40±4.71 kPa, p=0.0001). Emax value in the middle parenchyma of the testis showed no statistically significant difference between groups (p=0.053). Emax value in the twisted spermatic segment was higher than that in the lower spermatic segment with acute inflammation (166.61±60.07 vs 14.14±4.93, p=0.0001). In the torsion group, 12 testicular capsule areas showed “stiff ring sign” and all twisted segments of spermatic cord showed “stiff knot sign” but no signs were found in the inflammatory group.Conclusions: “Stiff ring sign” of testis, “stiff knot sign” of spermatic cord, high stiffness of the testicular capsule and in the twisted spermatic segment are the typical SWE findings of testicular torsion, with important clinical value in the differential diagnosis of testicular torsion and acute orchiditis.

The children presenting with acute scrotum have many diseases in differential diagnosis and testicular torsion in undescended testis and normal testis is an important consideration. Torsion of the testis, or more correctly, torsion of the spermatic cord, is a surgical emergency because it causes strangulation of gonadal blood supply with subsequent testicular necrosis and atrophy. In most of cases history and physical examination are sufficient to make an accurate diagnosis. While other causes may require simple treatment but torsion require immediate exploration to save the testis. Early diagnosis and prompt treatment is essential to help such children.

In this article, based on two clinical examples, the possibilities of multiparametric ultrasound in the differential diagnosis of metastatic and lymphoproliferative changes in lymph nodes in primary-multiple malignant tumors, including breast cancer and lym - phoma, are evaluated. Multiparameteric ultrasound includes B-mode, color and energy Doppler imaging, strain elastography, shear wave elastography and contrast-enhanced ultrasound (CEUS). Standardization and reproducibility of these ultrasound techniques will allow to objectify the study, obtaining specific indicators of shear wave velocity in the zones of interest and specific signs of contrast enhancement, which can be used as impor tant differential diagnostic tool in oncology.

BACKGROUND: In the past ten years, liver biopsies have been used as a method to accurately diagnose the stage of fibrosis. OBJECTIVE: This study aimed to evaluate whether body position and exercise affect the measurement of liver Young’s modulus of healthy volunteers by real-time shear wave elastography (RT-SWE). Methods: RT-SWE was used to measure liver Young’s modulus in the supine and left lateral positions of 70 healthy volunteers at rest and measure the liver Young’s modulus in the lying position before exercise, and at zero, five, and ten minutes of rest after exercise. RESULTS: The liver Young’s modulus in the left lateral position was significantly higher than in the supine position (P< 0.05), and the measured value in the supine position was more stable than the left lateral position. The liver Young’s modulus measured at zero minutes after exercise was significantly higher than that measured before exercise (P< 0.05). The liver Young’s modulus measured at five minutes after exercise was significantly higher than that measured at zero minutes after exercise (P<0.05) and was not statistically different from the measured value before exercise (P> 0.05). The liver Young’s modulus measured at ten minutes after exercise was significantly higher from that measured at zero minutes after exercise (P< 0.05) and was not statistically different from the measured value at five minutes after exercise (P> 0.05). CONCLUSION: Body position and exercise have a significant impact on the measurement of liver Young’s modulus. It is recommended that the examinees take a supine position during the measurement, and measurement should be conducted at least ten minutes after exercise.
