Diagnosis of Colorectal Polyps Using Optical Projection Tomography
… Optical Project Tomography in the diagnosis of colorectal polyps. Colonic polypoid cancers are the earliest detectable form of colorectal cancer and can potentially be cured if completely excised. The diagnosis using conventional 2D histopathology can be difficult due to epithelial displacement …

Analysis of Colorectal Polyps in Optical Projection Tomography
… projection tomography enables 3-D imaging of colorectal polyps at resolutions of 5 – 10 μm. This thesis presents image analysis methods for the polyp diagnosis from such images. Specifically, we investigate 3-D texture-based recognition methods, as well as weakly supervised classification …

The prevalence and characteristics of incidental colorectal polyps in patients undergoing colonoscopy at a South African tertiary institution
… a lack of data on the frequency, and pattern of colorectal adenomas in subSaharan Africa, to guide diagnostic and preventative strategies for CRC in the region. This study aimed to describe polyp characteristics, and adenoma frequency in patients at average risk of CRC undergoing colonoscopy for …

The utilisation of high frequency mini probe colonoscopic ultrasound in the assessment of colorectal disease
… with assessment of colonic cancer, malignant colorectal polyps, rectal polyps and diverticular disease<br/>High frequency 12 and 20 MHz ultrasound were used to locally stage colonic cancer and compare this to conventional CT in patients undergoing elective colonic resection. In addition, depth …

Availability of Dental Anomaly Phenotype In Individuals With Familial Adenomatous Polyposis
… polyposis (FAP), an autosomal dominant colorectal cancer predisposition associated with the development of hundreds to thousands of adenomatous colorectal polyps beginning in childhood or adolescence. Both malignant and non-malignant extracolonic manifestations are associated with …

In-Vivo Ct Dosimetry During Virtual Colonoscopy
… is a minimally invasive means for identifying colorectal polyps and colorectal lesions by insufflating a patient’s bowel, applying contrast agent via rectal catheter, and performing multi-detector computed tomography (MDCT) scans. The technique is recommended for colonic health screening by the …

Beta-catenin Complexes in Colorectal Cancer
… that initiate and drive the progression of colorectal cancer cause defects in key signalling pathways that affect cell function. The Wnt signalling pathway is a key pathway that is disrupted in colorectal cancer and β-catenin is the key mediator of Wnt signalling. β-catenin is a …

Endoscopy-focused primary, secondary and tertiary prevention of colorectal cancer
Colorectal cancer (CRC) is among the commonest and deadliest types of cancer. It is the second highest in economic burden among all cancers and the thirteenth of all diseases in Australia. In Japan, it has been gaining importance and in 2018 CRC was identified as second in incidence among all …
