The haustra (sg.: haustrum) of the colon are the small pouches caused by sacculation (sac formation), which give the colon its segmented appearance. The teniae coli run the length of …

If the haustral folds thicken and the hypertrophy or contracture of the muscle layer due to prolonged inflammatory change, the lumen narrows and the haustral folds can be lost. As a …

Haustral contractions are slow segmenting movements that occur every 25 minutes. One haustrum distends as it fills, which stimulates muscles to contract, pushing the contents to the …

Haustral folds are colon wall protrusions implicated for high polyp miss rate during optical colonoscopy procedures. If segmented accurately, haustral folds can allow for better …

Fold segmentation may help reduce the structural complexity, and the folds can serve as anatomic reference for computed tomographic colonography (CTC). Therefore, in this study, …

2019年12月26日 · Haustral markings are the radiological appearance of the haustral folds within the colon. Disappearance of the haustral folds results in the lead pipe appearance of ulcerative …

The haustral rows have specific anatomic relationships to extraperitoneal and intraperitoneal structures and mesenteric attachments. This organization of the haustral pattern can be …

Since the taeniae are shorter than the length of the colon itself, their tethering action in relation to the circular muscle results in the characteristic haustral sacculations. The colonic haustra are …

We propose a novel method to establish correspondence between the two acquisitions automatically. The problem is first simplified by detecting haustral folds using a graph cut …

Normal haustral markings in the colon.

The haustral folds are very thick (arrowheads), leading to a sign known as 'thumbprinting.' This patient with ulcerative colitis has a featureless segment of transverse colon with loss of the …

Haustral folds are colon wall protrusions implicated for high polyp miss rate during optical colonoscopy procedures. If segmented accurately, haustral folds can allow for better …

Haustral folds, which can be frequently demonstrated, helps differentiate small from large bowel loops. In early gestation, haustral folds appear as thin linear echoes within the lumen of the …

When haustral folds are significantly thickened and protrude into the bowel lumen, they can trap the positive oral contrast material, an appearance known as the “accordion sign”. This sign …

This study examined regional differences in colonic haustral fold height using CT colonography in 50 asymptomatic patients. Results found significantly taller haustral folds in the ascending colon.

2019年6月23日 · Widening of the haustral clefts with loss of the parallel lines is an early manifestation of ulcerative colitis and is more obvious on radiographs than the mucosal …

2024年11月7日 · Bowel wall thickening is a useful finding on imaging studies and has a number of different causes. The reason for bowel wall thickening depends on the underlying etiology but …

Another similar method proposed by Huang et al. 14 detected haustral folds using a curvature-based filter and assigned color to aid the identification of the teniae coli more quickly.
