Development of High-Precision Three-Dimensional Images for Colonoscopy

Background: For three-dimensional image analysis, SYNAPSE VINCENT (Fujifilm, Japan) has been applied. Authors have continued various clinical practice and research with image study by computer analysis.
Patient and Method: The patient is a 65-year-old female with further evaluation of colon. Method included abdominal computed tomography (CT) scan associated with injecting necessary amount of air from the anus. With maintaining this condition, CT scan was conducted two times of supine position and prone position.
Results: The case had sigmoid cancer, which was presented irregular surface texture. Further, she had colon polyp in the sigmoid colon and diverticula in the descending colon. These images were presented in the display associated with i) the position and direction for observation, ii) CT image of the corresponding point, iii) endoscopic image for the corresponding region.
Discussion: This image analysis system would be useful for clinical diagnosis, because the images have multiple angles and related situations of colon mucosa, folds, and stiffness and so on. The combined data can provide significant information including coronal, horizontal and sagittal planes. When the surgeon operates colon cancer, he can make the correct imagination of the lesion in advance. It seems to be beneficial for smooth treatment of surgical operation.
