整体斑块负荷(P1–P4)#
SCCT 2014
指南要求描述病变范围,但没有整体斑块负荷分级。唯一的整体指标是钙化积分(Agatston 总分及百分位数),且仅在加做平扫时获得。
SCCT 2014,第4节(Noncontrast coronary interpretation: coronary calcium scoring),p. 345;表4,p. 347 · “at the minimum, the total calcium score should be reported as well as the percentile as compared with age and gender nomograms.”
SCCT 2026
整体斑块负荷是强推荐的报告要素。以目测分为轻度、中度、重度或广泛(P1–P4),并结合钙化积分或 SIS(表3)。斑块体积定量测量为可选项(弱推荐,1.3)。
SCCT 2026,表5,p. 51;表3,p. 49;“c. Plaque volume”一节,p. 14;表6,p. 52 · “Plaque burden assessment is performed qualitatively as mild, moderate, severe, or extensive in combination with either the calcium score or the segmental involvement score.”
实际应用: 凡有斑块的报告,除狭窄分类外,还应写一行整体斑块负荷,例如“斑块负荷:中度(P2;SIS 4)”。若未做平扫钙化积分,则以 SIS 或目测估计斑块负荷。
