Contrast Ultrasound

Purpose: To compare the capabilities and evaluate the effectiveness of gray-scale B-mode, Doppler mapping and contrast enhanced in the assessment of cystic renal lesions.Material and methods: Ultrasound examination (US) was performed in 61 patients with cystic kidney formations (category Bosniak ≥ II). Cysts of categories Bosniak ≥ III were histologically verified, rest (categories II–IIF) were under follow up. All patients underwent gray-scale ultrasound, color Doppler imaging and contrast enhanced (CEUS).Results: The efficiency of the B mode was: sensitivity 55.6 %; specificity 72.1 %; accuracy 62.3 %, in the CDI mode these indicators were 52.8; 80.1; 63.9 %, respectively. Contrast ultrasound significantly increased the capabilities of the method, and also made it possible to evaluate cystic formations according to the Bosniak criteria with indicators of the effectiveness of the method up to 100.0; 92.0; 96.7 %, respectively.Conclusions: CEUS demonstrated high informative value in the assessment of renal cystic formations in comparison with native ultrasound and Doppler modes, and therefore the technique should be considered as promising for inclusion in the algorithm of examination of complex renal cysts.

Tumor Thrombi

Tumors of adrenal and thyroid glands have been associated with vascular invasions—so-called tumor thrombi, both in humans and dogs. The detection and characterization of venous thrombi is an important diagnostic step in patients with primary tumors for both surgical planning and prognosis. The aim of this study was to describe the use of contrast-enhanced ultrasonography (CEUS) for the characterization of tumor thrombi. Dogs with tumor thrombus who underwent bi-dimensional ultrasound (B-mode US) and CEUS were included. Seven dogs were enrolled in this retrospective case series. On B-mode US, all thrombi were visualized, and vascular distension and thrombus-tumor continuity were seen in three and two cases, respectively. On color Doppler examination, all thrombi were identified, seemed non-occlusive and only two presented vascularity. On CEUS, arterial-phase enhancement and washout in the venous phase were observed in all cases. Non-enhancing areas were identified in the tumor thrombi most likely representing non-vascularized tissue that could potentially be embolized in the lungs after fragmentation of the tumor thrombi. On the basis of these preliminary study, CEUS appeared to be useful for the characterization of malignant intravascular invasion.
