“…Our results of improved vessel delineation in pediatric liver transplants are in accordance with initial findings in adult patients assessing the hepatic vasculature and hypervascular hepatic tumors with B-flow, as well as detailed kidney transplant evaluation in children [16,[34][35][36]. Similar findings have been reported for superb microvascular imaging (SMI), which shares advantages with B-flow.…”

(1) Background: Accurate hepatic artery (HA) depiction following pediatric liver transplantation (LT) is essential for graft surveillance but challenging on ultrasound (US). This study assesses if improved HA delineation can be achieved by recording two-dimensional US volumes in Color Doppler (CD) and B-flow technique. (2) Methods: Of 42 consecutive LT, 37 cases were included, and HA delineation was retrospectively rated using a four-point score (0 = HA not detectable, 3 = HA fully detectable, separable from portal vein) within 48 h post-LT (U1) and before discharge (U2). (3) Results: Adding B-flow compared with CD alone showed superior results at neohilar (U1: 2.2 ± 1.0 vs. 1.1 ± 0.8, p < 0.0001; U2: 2.5 ± 0.8 vs. 1.5 ± 0.9, p < 0.0001) and segmental levels (U1: 2.8 ± 0.6 vs. 0.6 ± 0.8, p < 0.0001; U2: 2.8 ± 0.6 vs. 0.7 ± 0.5, p < 0.0001). (4) Conclusions: Standardized US volume recordings combining B-flow and CD can effectively delineate the HA along its vascular course in pediatric LT. The technique should be further evaluated as a standard monitoring instrument to rule out vascular complications after LT.

“…21,22 In terms of perfusion, Andrioli and Valcavi 23 have shown in their study in thyroid nodules that B-Flow imaging was better able to suppress unwanted signals in thyroid nodules and boost weak signals from blood vessels to show the completeness of ablation in these nodules. Matsumoto et al 24 in their study showed that B-Flow detected hepatic tumor blood flow with sensitivity as high as that of color Doppler.…”

B-Flow imaging of the placenta: A feasibility study

et al. 2018

B-Flow imaging directly displays the flowing intravascular echoes during real-time gray-scale ultrasound without using Doppler techniques. The objective of our study was to evaluate the feasibility of B-Flow imaging in the placenta and to evaluate the artifacts seen on B-Flow imaging. After IRB approval, 36 women (17 normal and 19 high risk women) were enrolled in our study. B-Flow images were acquired on GE LOGIC E9 machine. Retrospective analysis of the B-Flow and cine capture images was performed for artifacts and for vessels visualized. Pregnant women enrolled in the study ranged from 19 to 43 years of age with an average age of 31.7 years. Gestational age varied from 17 weeks and five days to 36 weeks and three days with an average of 26 weeks and three days. From a total of 161 B-Flow images reviewed by one researcher, 15 images were acceptable with no evidence of artifact. The remainder of the images had some artifact in them. For the 36 women with color Doppler and B-Flow images reviewed by the two independent blinded reviewers, a total of 144 reads were obtained. More small horizontal (p = 0.046) and small vertical running vessels (p < 0.001) were identified with B-Flow than color Doppler images. B-Flow is capable of showing perfusion in a human placenta; however, recognizing artifacts and modifying the image acquisition to reduce artifacts is necessary with this new technique to acquire the best images for interpretation.

“…The findings of US elastography suggest the lesion was benign. B-flow imaging neither reduces the frame rate nor suffers from artifacts such as blooming or wall overwriting, as the Color Doppler mode does; thus, this technique can display the true hemodynamics of the lesion in real time, especially at low speed [ 33 , 34 ]. B-flow imaging was reported to be used to distinguish hepatic lesions between benign and malignant ones.…”

Added Value of Ultrasound-Based Multimodal Imaging to Diagnose Hepatic Sclerosed Hemangioma before Biopsy and Resection

et al. 2022

Imaging methods have the overwhelming advantage of being non-invasive in the diagnosis of hepatic lesions and, thanks to technical developments in the field of ultrasound (US), radiation exposure can also be avoided in many clinical situations. In particular, contrast-enhanced US (CEUS) outperforms other radiological methods in regard to real-time images, repeatability, and prompt reporting and demonstrates relatively few contraindications and adverse reactions. In this study, we reported in detail a rare benign tumor: hepatic sclerosed hemangioma (HSH). We described US-based multimodal imaging (B-flow imaging, US elastography, and Sonazoid CEUS) features of this HSH case. Furthermore, by summarizing the recently published literature on the imaging diagnosis of HSH, we offered readers comprehensive knowledge of conventional imaging methods (CT, MRI) and CEUS in the diagnosis of HSH and preliminarily discussed their mechanism of pathology-based diagnosis. Our multimodal imaging approach may provide a diagnostic strategy for HSH, thus avoiding unnecessary biopsy or resection.
