Colon cancer is the second leading cause of cancer-related death in the United States, and can be prevented by the removal of precancerous colon polyps. For colon diagnosis, computed tomography colonography (CTC) has been proposed as a minimally invasive technique, and computer aided diagnosis (CAD) systems using CTC data are a rapidly evolving tool to localize, detect, and identify colon polyps....
While segmentation of the small bowel on CT scans is helpful for diagnosis and surgery planning, it is challenging to reproducibly identify specific locations within the small bowel. Assigning anatomical names to the individual mesenteric arteries supplying the small bowel may enable more precise lesion localization. It also enables registration of the small bowel from CT scans before and after surgery...
Colitis is inflammation of the colon that is frequently associated with infection and immune compromise. In this paper, we propose an automatic method for colitis detection in abdominal CT scans. We first used a visual codebook constructed by clustering feature vectors from a set of training image patches to detect the suspicious colitis regions. The initial detections included false detection points...
Due to the low image contrast and high tortuosity of the small bowel on CT scans, it is difficult for even experienced radiologists to localize small bowel. To facilitate this, we propose a novel mesenteric vasculature-guided method for small bowel region segmentation on high-resolution contrast-enhanced CT angiography (CTA) scans. It is essential and useful for further localizing small bowel tumors...
This study aimed to analyze the computed tomographic (CT) various findings of mucoepidermoid carcinoma of the lung and to improve the diagnostic efficacy for such tumor.Sixteen consecutive patients with mucoepidermoid carcinoma of the lung confirmed by pathology were reviewed retrospectively. All the patients had undergone unenhanced and contrast-enhanced examinations; one of them also had undergone...
Background We analyze the computed tomography (CT) findings of a peripheral primitive neuroectodermal tumor (pPNET) arising in the abdominopelvic cavity and to improve understanding of the CT images of the tumor. Materials and methods Twelve cases of pPNET confirmed by histopathology were analyzed retrospectively. Image characteristics of CT scanning were analyzed and compared with the pathology...
