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.

Flat-panel CT (FPCT) allows cross-sectional parenchymal, vascular and perfusion imaging within the angiography suite, which could greatly facilitate acute stroke management. We hypothesized that FPCT ...
Typically, continuous wave spectroscopy (CWS) can be used to accurately quantify biological tissue optical properties (μ a and μ s ') by employing the diffuse reflectance information acquired at mul...
Computed tomography (CT) is most commonly used as a noninvasive approach in diagnosis of internal organ injures. Use of multi-slice spiral CT becomes more popular in the trauma medicine because of its...
Many different intestinal parasite species can co-occur in the same population. However, classic diagnostic tools can only frame a particular group of intestinal parasite species. Hence, one or two te...
To assess the diagnostic accuracy of serum Cancer Antigen 125 (CA 125)≥30units/milliliter (u/ml) for diagnosing endometriosis in symptomatic women.
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...
The purpose of this study is to evaluate the diagnostic accuracy of multi-detector computed tomography using 320 detectors for identifying the combination of coronary artery stenosis ≥ 5...
Clinical study to evaluate diagnostic accuracy of low dose contrast enhanced dual energy mammography imaging (CEDEM+PRIME) in comparison with CE-MRI The primary objective of this clinical ...
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).
Very small encapsulated gas bubbles (diameters of micrometers) that can be used as CONTRAST MEDIA, and in other diagnostic and therapeutic applications. Upon exposure to sufficiently intense ultrasound, microbubbles will cavitate, rupture, disappear, release gas content, etc. Such characteristics of the microbubbles can be used to enhance diagnostic tests, dissolve blood clots, and deliver drugs or genes for therapy.
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...
