Ladder-Like Low Iodine Delivery Rate Injection Protocols Based on BMI at 70 KV by Automated Tube Voltage Selection in Coronary CTA

Figure 4

Graphs show the distribution of aortic root enhancement plotted against body weight (a), body surface area (b), and blood volume (c). A medium negative correlation was observed between enhancement and BW(r = −0.421), BSA(r = −0.457), and BV(r = −0.477). Blood volume has the highest correlation. Ninety-five percent of CIs (dotted fitting lines) are fit to the regression line (solid fitting line). o = male patients, + = female patients.
