Transcutaneous perianal sonography: A sensitive method for the detection of perianal inflammatory lesions in Crohn’s disease

Figure 6 PAUS (A + B) and MRI (C + D) imaging (coronary fat-saturated T1-SE sequence after gadolinium administration) of a perianal abscess. In contrast to MRI, PAUS was able to clearly identify a connection between the rectum and the abscess (A + C). Both methods could identify a sinus track that began within the abscess and ended in the gluteal fat (B + D). A scale (cm) is shown on the left side of the PAUS images for orientation.
