In the article titled "Relative Threshold of Detection of Active
Arterial Bleeding: In Vitro Comparison of MDCT and Digital Subtraction
Angiography" that appeared in the November 2007 issue of AJR
(AJR 2007;
189:1059;W238–W246), all four studies mentioned in the Results
section of the abstract should have the same units, i.e., mL/min, not mL/s, as
cited for the last two studies. The correct sentence in the Results paragraph
of the abstract should read: "The threshold to detect bleeding was as
follows for each study: For IV contrast-enhanced MDCT (study 1), it was 0.35
mL/min; DSA with a catheter 10 cm proximal to the holes (study 2), 0.96
mL/min; DSA with a catheter at the holes (study 3), 0.05 mL/min or lower; and
intraarterial selective MDCT (study 4), 0.05 mL/min or lower."
We regret these errors.
