“…Benign lesions typically show no enhancement; this reliably confirms benignity with a 100% PPV [112]. CEUS can identify more septa, characterize them as thicker and pick up solid components within cystic lesions at least as accurately as CT [106,107,109,112]. CEUS can demonstrate slow and low flow within lesions and allows their characterization as solid [113].…”

“…CEUS may assess vascular dynamics to predict graft success or failure: if the allograft does not enhance or lacks cortical or regional enhancement, this may indicate an inflow or outflow problem [109]. CEUS can also improve the vessels' conspicuity, as it is not angle dependent like Doppler US [106,107].…”

Contrast-enhanced ultrasound (CEUS) allows a real-time assessment of the vascular pattern of different types of lesions, as it has no renal or liver toxicity, it lacks radiation exposure and it is also cheaper than other imaging methods, having a diagnostic capability that matches contrast-enhanced CT or MRI. In Romania CEUS is used more and more, especially by clinicians, and since some centres have extensive experience in this domain, we felt the need to disseminate our expertise in order to implement this method in as many centres as possible. These Guidelines present the clinical applications of CEUS in the liver, spleen, pancreas, kidney, testis, bowel, intra-cavitary and endoscopic ultrasound, as well as other applications.

“…[11][12][13] Contrast-enhanced ultrasound (CEUS) is a method to monitor realtime renal microvascular perfusion. [14][15][16] The administration of microbubbles that absorb ultrasound (US) waves allows real-time imaging of the microcirculation, which may provide useful additional clinical information during surgery as compared with CO monitors. However, the clinical significance of poor renal microvascular perfusion during surgery has been little studied.…”

This issue of Clinical Hemorheology and Microcirculation is dedicated to the developments in the application of high resolution ultrasound in clinical diagnostics.The editors sought to provide information on the latest procedures for ultrasound bringing together outstanding original articles and reviews about new diagnostic information obtained by recent technological advances but also clarify well-established or controversial subjects. A very important step forward in ultrasound technology towards clinical application was the introduction of microbubbles as contrast enhancer. Contrast enhanced ultrasound (CEUS), performed with the intravenous injection of microbubble contrast agents applying the low mechanical index (MI) technique of contrast harmonic imaging has expanded the horizon for ultrasound imaging. CEUS provides a technique with superb sensitivity from early arterial phase up to late venous enhancement in dynamic realtime vascular imaging. For the first time, this ultrasound technology allows the non-invasive demonstration of blood flow of inner organs at a microcirculatory level [1,2]. Further, the purely intravascular microbubbles enable ultrasound to be used to monitor changes in the blood flow of tumors and in inflamed areas in a diagnostic approach but also for therapy control. Its performance without any requirement for ionizing radiation and with no nephrotoxicity makes it a compelling choice in many clinical arenas and is now FDA approved for liver imaging, and also for children [1][2][3][4][5][6][7][8].In this special issue, a first study evaluated factors which are associated with the initial incomplete ablation in radiofrequency ablation (RFA) for thyroid nodules [2]. Recent intraoperative studies reported the results of CEUS for immediate assessment of ablation status after RFA of hepatic malignancies [3]. These two articles showed the benefit of CEUS in the treatment control for ablation of solid nodules in various organs in terms of the virtues of CEUS such as real-time scanning, easy performance, and immediate assessment. In addition to qualitative evaluation for characterization [4,5], quantitative evaluation of blood flow perfusion is also available with use of CEUS [6]. Other important applications are the assessment of vascular diseases such as vascular complications after liver transplantation or the detection of endoleaks after endovascular aortic repair (EVAR) [7,8] or post-operative complications [9].
