Computed Tomography is undeniably the most useful tool to confirm the suspected diagnosis of acute left-colonic diverticulitis and to objectively grade its severity into moderate diverticulitis (no signs of colonic perforation) and severe diverticulitis (signs of colonic perforation). Indeed, the severity of acute diverticulitis is statistically predictive of the risk both to need surgical treatment of the first episode of acute diverticulitis, and to follow a complicated evolution after successful conservative treatment of the acute phase. Consequently, CT brings a major contribution to define the place of surgery during the acute phase of diverticulitis, and, later on, inside the long-term evolution of the disease after initial successful conservative treatment.
计算机断层扫描无疑是用于确诊急性左半结肠憩室炎疑似诊断并客观地将其严重程度分为中度憩室炎（无结肠穿孔迹象）和重度憩室炎（有结肠穿孔迹象）的最有用工具。事实上，急性憩室炎的严重程度在统计学上可预测首次急性憩室炎发作时需要手术治疗的风险，以及在急性期成功保守治疗后病情出现复杂演变的风险。因此，CT对于确定憩室炎急性期的手术时机以及随后在初始成功保守治疗后疾病的长期演变过程中发挥着重要作用。
