Overview
There are no echocardiography or ultrasound findings associated with celiac disease.
Echocardiography/Ultrasound
Ultrasound diagnostic parameters in celiac disease
- Increased gallbladder volume (r.v.≤ 20mL)
- It has an excellent specificity with a moderate sensitivity
- Dilated small bowel loops + increased fluid content (r.v.≤ 2.5 cm)
- It has an excellent sensitivity with a moderate specificity
- Thickened small bowel wall 91 8.0 0.27 39 98 (r.v.≤ 3 mm)
- It has an excellent specificity with a moderate sensitivity
- Increased peristalsis
- It has a both good sensitivity and specificity
- Free abdominal fluid
- It has an excellent specificity with a low sensitivity
- Enlarged mesenteric lymph nodes (r.v.≤ 5 mm)
- It has an excellent specificity with a low sensitivity
Among these parameters, the best sensitivity is seen with assessing dilated small bowel loops plus increased fluid content parameter, and the best specificity is seen with assessing enlarged mesenteric lymph nodes.
Arterial basal and postprandial splanchnic blood flow by doppler-US
Doppler arterial ultrasound can be considered as a non-sensitive diagnostic way.
- In fasting condition, there is an increase in superior mesenteric artery velocity and flow, with a lower resistance, and a higher portal vein velocity and flow.
- In postprandial phase all the above mentioned parameters may show a lower variation
Abdominal ultrasound role in the diagnosis of the complications of celiac disease intestinal lymphoma and small bowel adeocarcinoma
- Bull’s eye or target pattern
- Due to telescoping of bowel to form an inner loop
- Pseudokidney sign
- A non-specific indicator of bowel disease
- Related to an eccentric and localized bowel wall thickening
Ultrasound is useful in both the cancer location determination and staging of the cancer. Furthermore, ultrasound helps with both a detailed characterization of adjacent or distant lymph nodes, and deciding on the necessity of lymph node biopsy. Ultrasound has a low sensitivity for intestinal lymphoma diagnosis and should not be considered as the first line diagnostic test.
