In this study, researchers from Spain evaluated contrast-enhanced power Doppler ultrasound for the detection and follow-up of local complications in Crohn's disease.
The research team examined 28 patients with suspected abdominal inflammatory mass. They used power Doppler ultrasound before and after IV administration of the ultrasound contrast agent. They evaluated vascularity within and/or around the mass.
Color Doppler flow was characterized as clearly visible, minimally visible or absent.

In addition, all the patients underwent a post-contrast computed tomography exam.
The team found that after the administration of contrast medium, power Doppler ultrasound, allowed the detection of small inflammatory masses in Crohn's disease.
This was particularly true for those under 2 cm in diameter, when compared with computed tomography.
Dr José Esteban's team concluded, "Contrast-enhanced power Doppler ultrasound is a sensitive method for the detection of small abdominal inflammatory masses and for differential diagnosis between phlegmon and abscess".
In a related article in the same publication Dr David Sallomi reviews techniques used for the detection of inflammatory abdominal masses in Crohn's disease.
He discusses the benefits of contrast-enhanced power Doppler ultrasound, finding that it has a high sensitivity and specificity in the detection and evaluation of inflammatory masses.
The use of contrast-enhanced power Doppler ultrasound "facilitates assessment of disease progression and response to treatment", Dr Sallomi concludes.
