To study the diagnostic accuracy of enhanced multi-detector CT virtual endoscopy (MDCT-VE) for small intestinal tumors. MATERIALS AND
125 patients were examined by multi-detector CT (
54 on 4-slice; 71 on 64-slice) following standard gastrointestinal tract cleansing, oral double contrast aerogenesis agent, and rectal gas administration. Unenhanced CT was performed, followed by enhanced CT in supine (30 and 80s delay after 100 mL standard intravenous contrast medium) and prone positions (180s delay). Supplementary CT in the lateral position was performed if small bowel was not well-filled. Images were reviewed on post-processing workstations with Virtual Endoscopy software.
33/125 patients had proven small intestinal tumors: ten stromal tumors, nine lymphoma, eight adenocarcinomas, three hemangiomas, one each lipoma, Brunner gland adenoma, and hamartoma. 92 were nontumors. MDCT-VE correctly identified 30/33 cases with one false-positive diagnosis: sensitivity 90.9%, specificity 98.9% and accuracy 96.8%.
Small intestinal MDCT-VE technique has high diagnostic accuracy for the detection of intestinal tumors. Contrast enhancement and adequate intestinal tract gas-filling can improve the detection rate for small intestinal tumors.

The purpose of the study is to evaluate diagnostic performance of high iodine (iopamidol 370 mg/dl) content versus low iodine (iodixanol 300 mg/dl) content for diagnostic accuracy by contr...
To compare the diagnostic ability of 64-detector MDCT coronary angiography with conventional invasive coronary angiography in patients with suspected coronary artery disease.
The main hypothesis for this study is that the diagnostic approach of pulmonary embolism (PE) by evaluation of clinical probability, D-dimer test dosage and multi-detector helical computed...

An antennapedia-like homeodomain transcription factor that regulates the expression of multiple genes in the INTESTINAL MUCOSA. It plays a critical role in many processes from early differentiation to maintenance of the intestinal epithelial lining of both the small and large intestine.
Tumors or cancer of the INTESTINES.
Tumors or cancer in the JEJUNUM region of the small intestine (INTESTINE, SMALL).
Tumors or cancer in the ILEUM region of the small intestine (INTESTINE, SMALL).
A condition caused by the lack of intestinal PERISTALSIS or INTESTINAL MOTILITY without any mechanical obstruction. This interference of the flow of INTESTINAL CONTENTS often leads to INTESTINAL OBSTRUCTION. Ileus may be classified into postoperative, inflammatory, metabolic, neurogenic, and drug-induced.
Radiology is the branch of medicine that studies imaging of the body; X-ray (basic, angiography, barium swallows), ultrasound, MRI, CT and PET. These imaging techniques can be used to diagnose, but also to treat a range of conditions, by allowing visuali...
