OCT, a technology already in use in the diagnosis of ophthalmological diseases, has been investigated as a tool for staging bladder cancer in this study. It is analogous to ultrasound B mode imaging except that it uses near infrared light as opposed to sound waves.[3] With a resolution of 10 to 20 μm, it is akin to using an optical microscope and micro-architectural features of the bladder wall can be seen.[4] The images obtained are cross-sectional and in real-time. As the depth of penetration is only 1 to 2 mm, though it is able to distinguish structural changes in the bladder wall involving the mucosa, lamina propria, and superficial muscularis properly, information on invasion of deeper layers and extravesical spread is not available.[5] In the OCT image, the mucosa generally appears as a dark, thin, clearly defined layer. The lamina propria gives a bright, distinct signal, whereas muscularis shows a darker, spindled appearance.[1]
Members enjoyed beautiful images of birds, wildlife, landscapes and butterflies. A number of spectacular photos featured the Goderich harbour at different times of the day and in different seasons and weather conditions.
