Multiparametric Ultrasound

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.

Histopathological Results

Objectives: To assess the value of contrast-enhanced ultrasound (CEUS) for diagnosing malignant non-mass breast lesions (NMLs) and to explore the CEUS diagnostic criteria. Methods: A total of 116 patients with 119 NMLs detected by conventional US were enrolled. Histopathological results were used as the reference standard. The enhancement characteristics of NMLs in CEUS were compared between malignant and benign NMLs. The CEUS diagnostic criteria for malignant NMLs were established using independent diagnostic indicators identified by binary logistic regression analysis. The diagnostic performance of Breast Imaging Reporting and Data System-US (BI-RADS-US), CEUS, and BI-RADS-US combined with CEUS was evaluated and compared. Results: Histopathological results showed 63 and 56 benign and malignant NMLs. Enhancement degree (OR = 5.75, p = 0.003), enhancement area (OR = 4.25, p = 0.005), and radial or penetrating vessels (OR = 7.54, p = 0.003) were independent diagnostic indicators included to establish the CEUS diagnostic criteria. The sensitivity and specificity of BI-RADS-US, CEUS, and BI-RADS-US combined with CEUS were 100 and 30.2%, 80.4 and 74.6%, and 94.6 and 77.8%, respectively; the corresponding areas under the receiver operating characteristic curve (AUC) were 0.819, 0.775, and 0.885, respectively. Conclusions: CEUS has a high specificity in malignant NML diagnosis based on the diagnostic criteria including enhancement degree, enhancement area, and radial or penetrating vessels, but with lower sensitivity than BI-RADS-US. The combination of CEUS and BI-RADS-US is an effective diagnostic tool with both high sensitivity and specificity for the diagnosis of malignant NMLs. Advances in knowledge: In this study, we assessed the diagnostic value of CEUS for malignant NMLs and constructed a feasible diagnostic criterion. We further revealed that the combination of CEUS and BI-RADS-US has a high diagnostic value for malignant NMLs.

High flow priapism caused by perineal trauma is a relatively rare disorder. Early diagnosis represents a mandatory condition for the therapeutic resolution. Ultrasound examination is affordable and a within reach method for diagnosis also in an emergency context. We present the case of a 56-year-old male patient with traumatic priapism which was subsequently investigated by contrast-enhanced ultrasound and shear wave elastography. This may be one of the first cases presented in the literature

The pilot results of the contrast — enhanced ultrasound (CEUS) application in the liver parenchyma assessment are presented in this article. 65 people aged 37 to 69 years were examined, 41 of them (63 %) with chronic viral hepatitis and 24 people (37 %) with established diagnosis of liver cirrhosis as the outcome of viral hepatitis. All patients underwent multiparametric ultrasound examination: ultrasound of the liver in B — mode, color Doppler’s mapping of liver vessels, 2D — Shear Wave Elastography (2DSWE) and CEUS. Liver biopsy and D — Shear Wave Elastography (2DSWE) were used as the reference method.
