Grey scale ultrasound in Crohn's disease.

Ultrasonography in the Detection of Crohn’s Disease and in the Differential Diagnosis of Inflammatory Bowel Disease

“…Ultrasonic (US) signs of Crohn's disease (CD) have been previously described in many uncontrolled studies [1][2][3][4][5][6][7][8] and in a few prospective, controlled investigations, in which sensitivity and specificity of US diag nostic criteria in CD were evaluated [9][10][11], The conclusions of these papers were that ultrasound examination is a suitable comple mentary method for the detection of CD. On the other hand, ultrasonography has been considered not useful to differentiate CD from ulcerative colitis (UC) [9], Yet, Dub bins [12], measuring bowel wall thickness by means of US in an uncontrolled study in 28 patients with inflammatory bowel disease (IBD) and Worlicek et al [13] in a con trolled, prospective study suggested a possi ble role of US in the differential diagnosis and follow-up of IBD.…”

Oral and IV Contrast Enhanced Ultrasonography of the digestive tract – a useful completion of the B-mode examination: a literature review and an exhaustive illustration through images

“…The most important sonographic finding is represented by the segmental wall thickening. The sensitivity of US is 75-94% and the specificity is 67-100% [26,31,32]. In the early activity phase of the disease a process of angiogenesis takes place in the mucosa and submucosa [33].…”
