Background & Aims:
The utility of ultrasound and color Doppler in the diagnosis and evaluation of inflammatory bowel diseases (IBD) has not been studied enough. Therefore, the aim of the current study was to evaluate the importance of conventional abdominal ultrasound and color Doppler in diagnosing IBD and assessing disease activity.
Methods:
The study was conducted at the National Hepatology and Tropical Medicine Research Institute (NHTMRI) between July 2018 and January 2019, in which 150 patients were suffering from diarrhea, dysentery, tenesmus, or rectal bleeding were evaluated by colonoscopy, high-resolution ultrasound, and color Doppler scans.
Results:
The present study was conducted on 150 patients; 84 (56%) had ulcerative colitis (UC), 16 (10.7%) had Crohn's disease (CD), and 50 (33.3%) had normal colonoscopy results with a mean age 37.2 ± 9.059. The superior mesenteric Artery Peak Systolic Velocity (SMA-PSV) and End Diastolic Velocity (EDV) were significantly higher in both UC and CD than in the control group; however, pulsatility index (PI) was significantly higher in the control group than both UC and CD. However, there was no significant difference between UC and CD. The inferior mesenteric artery PSV and EDV were significantly higher in both UC and CD than in the control group.
Conclusion:
Doppler ultrasound findings of SMA and IMA correlate with the incidence of inflammatory bowel disease, the site of disease, and its activity.

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...

01:27Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
01:20Ultrasound I: Abdominal Ultrasonography
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
