Contrast harmonic imaging for vascularization assessment of the small bowel in Crohn's disease: A feasibility study

Contrast harmonic imaging employing a multi-frequency linear transducer represents a new technique, which allows high resolution imaging of microcirculation in vivo. The aim of this study was the evaluation of this approach for assessing bowel wall vascularization in patients with active Crohn's disease. We evaluated this technique in 12 patients with active Crohn's disease. All patients had a CE MR-enteroclysis (MRE) as a baseline examination. Using a novel multi-frequency linear transducer (6–9MHz, Logig 9, GE) we examined the affected thickened small bowel applying power Doppler (PD) and coded duplex ultrasou…
