The April 2004 article titled "Triple-Phase Dynamic MRI of
Intratumoral Vessel Density and Hyalinization Grade in Uterine
Leiomyomas" (AJR
2004;182:10431050) contained the following errors.
The fourth sentence of Subjects and Methods in the abstract should have
read as follows: "The enhancement index (EI) of the leiomyoma
was calculated using the formula EI(t) =
[S(t) S(0)] /
S(0), where S(0) is the signal intensity
on pre-enhanced T1-weighted images and S(t) is the
signal intensity on each dynamic phase image (t = 20, 60, and 180
sec)."
In the second paragraph of the Discussion section, the fourth sentence
should have read as follows: "The correlation coefficient between
intratumoral vessel density and EI60 was the same as that
between intratumoral vessel density and EI180, although we
had theorized that the correlation coefficient for EI60
would be higher because EI180 reflected the permeability
of capillary vessels as well as the vascularity of the
tumor."
We regret these errors. These corrections have been made in AJR
online.
