Sonographic Imaging

Gallbladder carcinoma is rare and difficult to detect in the early stages of the disease process, due to lack of symptoms. Sonography is typically the first modality of choice for assessing gallbladder pathology due to its high sensitivity, portability, real-time imaging capability, and non-ionizing technique. Conventional gray-scale and color Doppler sonographic imaging may be ambiguous for diagnosing solid tumors, such as gallbladder carcinoma. In this case, gallbladder carcinoma was definitively diagnosed utilizing contrast-enhanced ultrasound, allowing for quick patient treatment options and an optimal surgical outcome.

Gallbladder perforation is a rare and severe complication of acute cholecystitis. Sonography is typically the first modality of choice for assessing gallbladder pathology due to its high sensitivity, portability, real-time imaging capability, and nonionizing technique. Gray-scale and color Doppler sonographic imaging may be equivocal for diagnosing perforation. In the presented case, gallbladder wall perforation was definitively diagnosed utilizing contrast-enhanced ultrasound, allowing for prompt treatment and a successful patient outcome.

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.

Background Microvascularization of the bowel wall can be visualized and quantified non-invasively by software-assisted analysis of derived time-intensity curves. Purpose To perform software-based quantification of bowel wall perfusion using quantitative contrast-enhanced ultrasound (CEUS) according to clinical response in patients with inflammatory bowel disease treated with vedolizumab. Material and Methods In a prospective study, in 18 out of 34 patients, high-frequency ultrasound of bowel wall thickness using color Doppler flow combined with CEUS was performed at baseline and after 14 weeks of treatment with vedolizumab. Clinical activity scores at week 14 were used to differentiate between responders and non-responders. CEUS parameters were calculated by software analysis of the video loops. Results Nine of 18 patients (11 with Crohn’s disease and seven with ulcerative colitis) showed response to treatment with vedolizumab. Overall, the responder group showed a significant decrease in the semi-quantitative color Doppler vascularization score. Amplitude-derived CEUS parameters of mural microvascularization such as peak enhancement or wash-in rate decreased in responders, in contrast with non-responders. Time-derived parameters remained stable or increased during treatment in all patients. Conclusion Analysis of bowel microvascularization by CEUS shows statistically significant changes in the wash-in-rate related to response of vedolizumab therapy.

Background and objectives: The aim of the present retrospective single-center study is to evaluate the diagnostic performance of contrast-enhanced ultrasound (CEUS) for assessing Bosniak III complex renal cystic lesions with histopathological validation. Materials and Methods: 49 patients with CEUS-categorized Bosniak III renal cystic lesions were included in this retrospective study. All patients underwent native B-mode, Color Doppler, contrast-enhanced ultrasound (CEUS) between 2010–2020. Eight and five patients underwent computed tomography (CT) and magnetic resonance imaging (MRI), respectively. Twenty-nine underwent (partial) nephrectomy allowing for histopathological analysis. The applied contrast agent for CEUS was a second-generation blood pool agent. Ultrasonography examinations were performed and interpreted by a single experienced radiologist with more than 15 years of experience (EFSUMB Level 3). Results: CEUS examinations were successfully performed in all included patients without registering any adverse effects. The malignancy rate of CEUS-categorized Bosniak III renal lesions accounted for 66%. Initially, cystic complexity was visualized in native B-mode. In none of the renal lesions hypervascularization was detected in Color Doppler. CEUS allowed for detection of contrast enhancement patterns in all included Bosniak III renal lesions. Delayed wash-out could be detected in 6/29 renal lesions. In two cases of histopathologically confirmed clear-cell RCC, appropriate up-grading from Bosniak IIF to III was achieved by CEUS. Conclusions: CEUS depicts a promising imaging modality for the precise diagnostic workup and stratification of renal cystic lesions according to the Bosniak classification system, thereby helping guidance of adequate clinical management in the future.
