“…Some of the studies have shown a significant difference between colon wall thickness among cases with moderate to severe colitis and cases of mild or inactive colitis either before or after treatment. 24,25 In our study the mural thickness of colon among new cases of UC (6.4±1.3mm) was significantly more than this value in cases who diagnosed as UC flare(5.5±1.7mm, P=0.02). Moreover average thickness of colon wall in active or new cases of UC (average 5.9, range 2-9mm) was significantly more than mural thickness in control group (average 3.3, range 3-4mm).…”

Aim: To evaluate diagnostic accuracy of ultrasonography in comparison with colonoscopy as gold standard for diagnosing of ulcerative colitis (UC). Method: In this prospective study, 114 participants who attended in Ahvaz Imam Hospital during March 2014 to February 2015 included. The participants divided into 2 groups: group A as 64 UC patients (flare or new case) and 50 participants as control group who attend for colorectal cancer screening or evaluation of rectorrhagia. All of the participants obtained a Trans abdominal ultrasonography after 8hours fasting and evaluated for colonic thickness in any involved region, loss of compressibility, peristaltic movement, mesenteric lymph nodes enlargement and presence or absence of ascites, fat stranding or stratification. Results: Ultrasonography sensitivity for diagnosing of moderate to severe UC in comparison with colonoscopy was between 52.56 to 86.36% based on different factors such as new onset or active disease, BMI, gender and region of involvement. In all of the situations the specificity was 100%. The sensitivity for diagnosing new cases of UC and pancolitis were 86.36% and 76.67% respectively and these figures were less among cases with BMI more than 25. The colonic wall thickness in new cases of UC (6.4±1.3mm) was significantly more than wall thickness among disease flare up (5.5±1.7mm) (P=0.02) and also average colon thickness in UC group (average 5.9mm , range 2-9mm) was significantly more than control group (average 3.3mm, range 3-4mm). Conclusion: The findings of current study prove that ultrasonography is not an ideal tool for evaluation of UC patients because its results could affect by several factors such as BMI and region of involvement.

“…Cross-sectional images of patients reveal the type and extent of their intestinal inflammation. The location and degree of inflammation and wall thickening determines the manifestation of IBD [118]. Further, these factors are heavily considered when diagnosing patients with IBD as opposed to other diseases.…”

A variety of seemingly non-specific symptoms manifest within the gastrointestinal (GI) tract, particularly in the colon, in response to inflammation, infection, or a combination thereof. Differentiation between symptom sources can often be achieved using various radiologic studies. Although it is not possible to provide a comprehensive survey of imaging gastrointestinal GI tract infections in a single article, the purpose of this review is to survey several topics on imaging of GI tract inflammation and infections. The review discusses such modalities as computed tomography, positron emission tomography, ultrasound, endoscopy, and magnetic resonance imaging while looking at up-an-coming technologies that could improve diagnoses and patient comfort. The discussion is accomplished through examining a combination of organ-based and organism-based approaches, with accompanying selected case examples. Specific focus is placed on the bacterial infections caused by Shigella spp., Escherichia coli, Clostridium difficile, Salmonella, and inflammatory conditions of diverticulitis and irritable bowel disease. These infectious and inflammatory diseases and their detection via molecular imaging will be compared including the appropriate differential diagnostic considerations.

“…Technetium-99-m hexamethyl-propyleneamine oxime (99mTc-HMPAO) labeled white blood cell scintigraphy is an imaging technique that employs radioactive isotopes to detect active inflammation [34] . It may be used in IBD to assess disease activity, but due to limited availability and high cost, it is not routinely performed.…”
