Computed Tomographic Colonography (CTC) produces 2-d and 3-d images of the colon using computed tomography (CT). The main goal of CTC is to detect small lumps on the colon surface called polyps, which are known to be precursors to colon cancer. Radiologists are therefore interested in exploring the inner surface of the colon to detect polyps. Polyps may be detected by visual inspection of colon...

Colon adenocarcinoma represents the third most frequent cause of death by cancer, being surpassed only by lung or stomach cancer, and it has motivated many studies in the past 5 decades. The probable diagnosis is usually based on clinical data, which mainly comprise anemia, low digestive tract bleeding, abdominal pain, and weight loss. Over the last 20 years, colonoscopy became the main investi...

background and aim: colon cancer is the third most prevalent cancer in iran. prolonged colon inflammation is an important factor, in the development of colon cancer. ginger has anti-inflammatory properties due to its content of [6]-gingerol and hence can play a role in the prevention of colon cancer. in this research the effects of ginger extract on reducing expression of the cox-2 gene in ht-2...

CT colonography (CTC) is a minimally invasive screening technique for colorectal polyps and colon cancer. Since electronic colon cleansing (ECC) cannot completely remove the presence of pseudo-polyps, most CTC protocols acquire both prone and supine images to improve the visualization of the lumen wall and to reduce false positives. Comparisons between the prone and supine images can be facilit...

Over the past years, due to increase of detection patients with early-stage stomach cancer and colorectal cancer, improvement survival rate, efforts have been made gradually develop concept sentinel lymph nodes in order improve postoperative quality life. The article presents review literature on feasibility intraoperative diagnosis choice surgical treatment tumors colon. Analytical work demons...

Dysplasia represents a preneoplastic status in multistep colon carcinogenesis. Whereas laborious preparation of thin sections is required for its diagnosis, we here show that newly defined aberrant crypt foci (ACF) simply mark the majority of the dysplasia on the whole colon. Specifically, decoloring of the azoxymethane-treated rat colon after scoring classical ACF (cACF) resulted in visualizat...
