Fig. 4 A,B: False scoring of Speckle artifact. (A) Hyper-attenuating noise in the distal RCA has been falsely scored due to these areas being highlighted by the auto-score option (oval). (B) With the auto score function off, the distal RCA (oval) can be clearly seen to contain speckled noise, but no areas of scorable calcification. Compare this noise artifact with real punctate calcification in figure 5.
