“…Contrast enhanced ultrasound (CEUS) is an upgrade to standard US, which is very helpful in evaluating PDC malfunction, peritoneal-pleural communication, leakage, and herniation, and in particular, it facilitates dynamic functional imaging of the catheter and its complications. The use of CEUS in peritoneal dialysis is simple, repeatable, safe, radiation-free, and appears to be less time-consuming and more cost-effective than other radiological imaging techniques such as peritoneography, computed tomography, magnetic resonance, and peritoneal scintigraphy [10].…”
