2024年10月4日 · The duodenum is a 20-30 cm C-shaped hollow viscus predominantly on the right side of the vertebral column. It lies at the level of L1-3 and the convexity of the duodenum (called the duodenal sweep by radiologists) usually encompasses the head of the pancreas.

2023年11月29日 · The duodenum is about 25 to 30 cm long (“twelve fingers' length”), C-shaped and is located in the upper abdomen at the level of L1-L3. The head of the pancreas lies in the C loop. It may be subdivided into four sections: superior part, descending part, horizontal part and ascending part.

2025年3月6日 · The duodenum is a C-shaped or horseshoe-shaped structure that lies in the upper abdomen near the midline between the level of the first and third lumbar vertebrae in the supine position (see the...

Distally, it is in continuation with the jejunum and ileum, with the proximal segment being the shortest and widest. Positioned inferiorly to the stomach, the duodenum is approximately 25 to 30 cm long.

2017年10月1日 · CT remains the first line imaging modality for the detection and characterization of a wide range of duodenal mass-forming lesions. The duodenum is a portion of the gastrointestinal tract that has both an extra- and intraperitoneal location [1].

2019年1月22日 · Duodenal loop: The patient lies prone on the compression pad to prevent barium flooding into the duodenum (additional views of the anterior wall of the duodenal loop can be taken in the right anterior oblique position).

In this article, we demonstrate the typical imaging features of various diseases involving the duodenum, such as developmental, traumatic, inflammatory, infectious, neoplastic, and postsurgical pathologic conditions in alphabetical order, focusing mainly on upper gastrointestinal series (UGIS) and CT but also some radiography, ultrasound, and ma...

The duodenum is a C-shaped loop of the small intestine. The concavity of the duodenal loop encloses the head of pancreas. The duodenum is situated in the abdominal cavity above the level of the umbilicus opposite to the L1, L2, L3 vertebrae.

We discuss the CT findings of some congenital, inflammatory, traumatic, and neoplastic pathologies of the duodenum along with the conventional barium studies of selected conditions. Pathologies of this C-shaped intestinal segment, derived from both foregut and midgut, are often overlooked in clinical practice and radiological literature.

2023年8月8日 · Note marked dilation of C-loop of the duodenum in the patient. The patient’s laboratory evaluation was unremarkable, and she did not have any prior medical or surgical history that could account for her complaints.
