Type C of mucosal blood flow. a and b show type C blood flow. This type of blood flow distribution is characterized by an obviously wide lamina propria interstitial space and blood flow crisscrossing into a network structure. In a, the fluorescence intensity of blood flow was homogeneous and reflects good capillary filling and a homogeneous distribution of blood flow. This is mainly seen in the unaffected segments and affected Mayo score 0 segments of UC patients and it is also found in the normal cecum and sigmoid colon. In b, the distribution of blood flow is more irregular and the distribution of fluorescein is uneven. This reflects a lack of blood flow in some parts of the capillaries. This type of blood flow is mainly distributed in the affected Mayo score 0 segments of UC patients
