There are no echocardiography/ultrasound findings associated with [disease name]. However, an echocardiography/ultrasound may be helpful in the diagnosis of complications of [disease name], which include [complication 1], [complication 2], and [complication 3].
Ultrasound
- Ultrasound may be helpful in the diagnosis of toxic megacolon. Findings on an ultrasound suggestive of toxic megacolon include:[1][2][3]
- Loss of haustra coli of the colon
- Hypoechoic and thickened bowel walls with irregular internal margins in the sigmoid and descending colon
- Prominent dilation of the transverse colon(>6 cm)
- Insignificant dilation of ileal bowel loops(diameter >18 mm) with increased intraluminal gas and fluid
