“…The MVFI is capable of real-time, highly detailed visualization of small velocity vessels without a contrast agent. MVFI uses advanced multidirectional filters, which can separate microvascular flow from tissue clutter by analyzing the signal's spatiotemporal coherence [6].…”

“…The spleen shares the property of sequestering and retaining ultrasound contrast microbubbles with the liver and is also ideally suited for ultrasound contrast imaging [5]. Microvascular flow imaging (MVFI) is an advanced Doppler ultrasound technique to visualize slow velocity flow in small-caliber vessels [6]. This is the first report on CEUS and MVFI aiding the diagnosis of a splenic hamartoma.…”

Splenic hamartoma is a rare benign vascular lesion of the spleen. A splenic mass was incidentally detected in an asymptomatic 65-year-old male during an abdominal ultrasound scan. The workup of the splenic lesion included an abdominal CT angiography (CTA), contrast-enhanced ultrasound (CEUS), and microvascular flow imaging Doppler sonography. The CT scan confirmed that the splenic mass had benign characteristics, and its contrast enhancement was similar to the spleen. The CEUS was able to rule out the possibility of hemangioma. Meanwhile, chronic compression of the celiac trunk and the filling of the splenic artery from collaterals were also detected on CTA. The imaging studies suggested a splenic hamartoma, and the diagnosis was confirmed by the result of a fine needle aspiration biopsy.

“…Hemangiomas were associated with a peripheral strip rim pattern or nodular rim pattern with dot-like spots, which can be related to the dilated peripheral vascular spaces. The spoke-wheel pattern of FNH is related to its internal vascular architecture, with intralesional arteries radiating from the center toward the periphery of the lesion [ 19 , 20 ]. Peripheral draining veins can also be visualized in FNH [ 21 ].…”

New microvascular ultrasound techniques: abdominal applications

Microvascular ultrasound (MVUS) is a new ultrasound technique that allows the detection of slow-velocity flow, providing the visualization of the blood flow in small vessels without the need of intravenous contrast agent administration. This technology has been integrated in the most recent ultrasound equipment and applied for the assessment of vascularization. Compared to conventional color Doppler and power Doppler imaging, MVUS provides higher capability to detect intralesional flow. A growing number of studies explored the potential applications in hepatobiliary, genitourinary, and vascular pathologies. Different flow patterns can be observed in hepatic and renal focal lesions providing information on tumor vascularity and improving the differential diagnosis. This article aims to provide a detailed review on the current evidences and applications of MVUS in abdominal imaging.

Contrast-enhanced ultrasound, microvascular imaging, elastography, and fat quantification have varying degrees of utility, with some applications in the pediatric setting mirroring that in adults and having unique uses when applied to children in others. This review will present novel ultrasound technologies and the clinical context in which they are applied to the pediatric abdomen. New ultrasound technologies have a broad range of applications in clinical practice and represent a powerful diagnostic tool with the potential to replace other imaging modalities, such as magnetic resonance imaging and computed tomography, in specific cases.
