Personalization of CM Injection Protocols in Coronary Computed Tomographic Angiography (People CT Trial)

Figure 3

Mean overall attenuation and mean attenuation for the right coronary artery (RCA), left main (LM), left anterior descending (LAD), and circumflex artery (Cx). Group CO resulted in an increased number of scans between 325 and 500HU. However, group BW had less scans <325 HU. All these differences were not significantly different. Of these three, group LBW had a lower attenuation and less scans >325 HU.
