Background: To evaluate the frequency of pathological findings determined on magnetic resonance (MR) enterography (MRE) in patients with Crohn’s Disease.Methods: A retrospective analysis of the MRE images was made in 34 female and 41 male patients (mean age 41 years) with Crohn’s disease. The prevalence of bowel wall (mural thickening, mural edema, mural fat deposits, mucosal enhancement, ulceration, cobblestone appearance, pseudopolyps) and mesenteric fatty tissue alterations (fatty tissue proliferation, mesenteric hypervascularity, enlarged lymph nodes, peri-enteric inflammation, reactive fluid), complications due to penetrating (fistula, sinus tract, abscess) and stenosing processes (fibrotic and inflammatory stenosis, obstruction, dilatation), and involvement of the colon were determined.Results: The most frequently observed changes in the bowel wall and mesenteric fatty tissue were mural thickening (98.7%) and enlargement of mesenteric lymph nodes (76%), respectively. Stenosis was the most common complication (76%). The most frequently seen pathology of the colon was ileocecal valve thickening and enhancement (74.7%).Conclusion: MR enterography is a useful imaging modality for the evaluation of changes in both the mesenteric fatty tissue and the bowel wall. As there is no use of ionizing radiation, MR enterography should be the preferred imaging modality during follow-up of patients with Crohn’s disease. 相似文献

Background: Non-invasive methods play an important role in clinical assessment of Crohn’s disease. Recent studies have highlighted the effectiveness and reliability of intestinal ultrasonography. We aimed to examine the relationship between intestinal ultrasonography and the clinical, endoscopic, and computed tomography enterography findings, and to assess the activity of Crohn’s disease.Methods: This was a 1-year prospective study involving patients diagnosed with Crohn’s Disease. Clinical and endoscopic activity indices, and intestinal ultrasonography and computed tomography enterography findings were evaluated. Intestinal wall thickness, mesenteric inflammation, lymphadenopathy, and complications were evaluated by intestinal ultrasonograpy and computed tomography enterography, while the superior mesenteric artery flow velocity, resistive index, and Limberg score were assessed by Doppler intestinal ultrasonography.Results: Seventy-nine patients with Crohn’s disease were included. A significant correlation was found between intestinal wall thickness, mesenteric inflammation, and complications in intestinal ultrasonography and computed tomography enterography (P = .0001). According to the receiver operating curve analysis, the intestinal wall thickness, and mesenteric inflammation were correlated with the Crohn’s Disease Activity Index, Harvey–Bradshaw Index, and SES-CD scores (P ˂ .05), and they were very effective in distinguishing active from inactive disease. According to the Crohn’s Disease Activity Index and SES-CD scores, Doppler flow velocity of the superior mesenteric artery was significantly higher in the active group than in the inactive group (P ˂ .05). The Limberg score was very consistent with the Crohn’s Disease Activity Index, Harvey–Bradshaw Index , and the results of the Simple Endoscopic Score for Crohn’s Disease (P < .0001).Conclusion: Our study showed that intestinal ultrasonography is an effective and reliable method for assessment of Crohn’s disease activity compared to clinical, endoscopic, and CTE findings. 相似文献

The authors report a case series describing four patients who developed small bowel obstruction following the use of psyllium seed husk as an oral contrast agent for computed tomography or magnetic resonance enterography. Radiologists who oversee computed tomography and magnetic resonance enterography should be aware of this potential complication when using psyllium seed husk and other bulking agents, particularly when imaging patients with known or suspected small bowel strictures or active inflammation. 相似文献

AIM: To highlight magnetic resonance enterography (MRE) for diagnosis of patients with refractory iron deficiency anemia and normal endoscopy results.METHODS: Fifty-three patients diagnosed with iron deficiency anemia refractory to treatment and normal gastroscopy and colonoscopy results were admitted to this prospective study between June 2013 and December 2013. All patients underwent a standardized MRE examination with a 1.5 Tesla magnetic resonance imaging system using two six-channel phased-array abdominal coils. Adequate bowel distention and fast imaging sequences were utilized to achieve diagnostic accuracy. All segments of the small bowel, duodenum, jejunum, and ileum were examined in detail. All cases were examined independently by two radiologists with > 5 years of experience in abdominal magnetic resonance imaging. A consensus reading was performed for each patient following image examination. Both radiologists were blinded to patient history, laboratory findings, and endoscopy results.RESULTS: Twenty (37.7%) male and 33 (62.3%) female patients were included in the study. The mean age of the patients was 52.2 ± 13.6 years (range: 19-81 years, median 51.0). The age difference between the male and female patient groups was not statistically significant (54.8 ± 16.3 years vs 50.7 ± 11.7 years). MRE results were normal for 49 patients (92.5%). Four patients had abnormal MRE results. One patient with antral thickening was diagnosed with antral gastritis in the second-look gastroscopy. One patient had focal wall thickening in the 3rd and 4th portions of the duodenum. The affected areas were biopsied in a subsequent duodenoscopy, and adenocarcinoma was diagnosed. One patient had a fistula and focal contrast enhancement in the distal ileal segments, consistent with Crohn’s disease. One patient had focal wall thickening with luminal narrowing in the mid-jejunum that was later biopsied during a double-balloon enteroscopy, and lymphoma was diagnosed.CONCLUSION: MRE is a non-invasive and effective alternative for evaluating possible malignancies of the small intestines and can serve as a guide for a second-look endoscopy. 相似文献

Background and study aimsThe treatment approach for Crohn’s disease (CD) is focused on mucosal healing and resolution of transmural inflammation. The aim of this study is to evaluate the correlation between computed tomography enterography (CTE) and other treatments, in particular, endoscopy and biochemical indicators, in newly diagnosed patients with CD.Patients and methodsOne hundred twenty-three patients with CD who received CTE in Xiangya Hospital, Central South University, China, from April 2017 to April 2019 were included. The clinical case data and imaging results were retrospectively reviewed. The clinical activity of CD was determined by the Crohn’s disease activity index (CDAI) score and biochemical indicators. The relationships between CTE and endoscopy, CDAI score, and inflammatory markers were evaluated.ResultsThe diagnostic rate of CTE of the 123CD patients was 68.3% (84/123). Logistic regression analysis showed that the specific CTE manifestations related to CD activity were intestinal wall stratification, comb sign, and abdominal abscesses (P < 0.05). Spearman’s rank correlation analysis showed that inflammatory markers positively correlated with different CTE imaging manifestations.ConclusionIntestinal CTE combined with endoscopy and biochemical indicators is both comprehensive and effective in evaluating the condition of CD patients. 相似文献

Purpose CT enterography (CTE) is a technique that provides detailed images of the small bowel by using a low Hounsfield unit oral
contrast media. This study was designed to correlate CTE findings with operative findings in patients with Crohn’s disease.
Methods We performed a retrospective study of all patients with Crohn’s disease of the small bowel or colon, who had CTE and subsequent
small bowel or colon surgery within three months after the CT examination. CTE findings of stricture, fistula, inflammatory
mass, abscess, and combinations of these abnormalities were compared with operative findings. Specialist radiologists and
fellowship-trained colorectal surgeons participated in the study. The Fisher’s exact test or chi-squared tests were used with
respect to categorical data, and the Wilcoxon’s rank-sum test was used for quantitative data.
Results In 36 patients, the presence or absence of stricture, fistula, abscess, or inflammatory mass was correctly determined by CTE
in 100, 94, 100, and 97 percent, respectively. The accuracy for stricture or fistula number was 83 and 86 percent, respectively.
There were nine patients with multiple disease phenotypes identified on CTE of which eight were confirmed at surgery. CTE
overestimated or underestimated the extent of disease in 11 patients (31 percent).
Conclusions CTE is an accurate preoperative diagnostic imaging study for small-bowel Crohn’s disease. The ability of this imaging study
to detect both luminal and extraluminal pathology is a distinct advantage of CTE compared with small-bowel contrast studies.
