实际应用： 判定无法评估之前，先在其他时相、其他平面和其他窗宽窗位下复核。若仍无法判读，写明节段和伪影，并描述可见的斑块。存在 N 时，CAD-RADS 2.0 仅在整体斑块负荷可以可靠评估时（例如借助钙化积分）才加上 P。其对分类的影响见 CAD-RADS 一节。

噪声没有专门控件。通过“报告草稿”中的“质量”选择框体现；若导致某节段无法判读，用编辑器中的“N”按钮标记该节段。选择“无诊断价值”且没有节段标记“N”时，病变图对整个检查套用 N 规则，见“检查整体图像质量”。标记“N”不会删除该节段的斑块，而是将其暂存，取消N后即恢复；如何在报告中描述该斑块，见“无法评估节段（无诊断价值）”。
管腔强化不单独记录。通过“报告草稿”中的“质量”选择框体现；因强化不足无法判读的节段，用编辑器中的“N”按钮标记。选择“无诊断价值”且没有节段标记“N”时，病变图对整个检查套用 N 规则，见“检查整体图像质量”。标记“N”不会删除该节段的斑块，而是将其暂存，取消N后即恢复；如何在报告中描述该斑块，见“无法评估节段（无诊断价值）”。
