  1. † The location of each breast lesion seen on ultrasound was reported using its "o'clock" location and its 1, 2, or 3 "zone" location relative to the distance from the nipple (i.e., zone 1 is the central-third of the breast field, zone 2 is the middle-third of the breast field, and zone 3 is peripheral-third of the breast field) [20, 21].
  2. * All sixteen breast lesions visualized on ultrasound were also identified on MRI. However, the three closely approximated lesions (lesion #3, #4, and #5) that were ultimately identified on ultrasound in the 9 o'clock axis of zone 3 of the right breast could not be distinguished as three separate areas of enhancement on MRI, but appeared as one vaguely defined area of enhancement on MRI.
  3. ‡ The volume of the ultrasound lesion was calculated using the formula of the volume of an ellipsoid [4/3·π·length axis radius·width axis radius·height axis radius], rather than using the formula of the volume of a cuboid [length·width·height], since the three-dimensional shape of any given ultrasound lesion generally better approximated that of an ellipsoid rather than that of a cuboid [10].
  4. Seven months after stopping hormonal contraception, lesion #9 measured 2.35 × 1.63 × 0.79 cm in size (volume 1.58 cm3), consisting of a 166% volume reduction.
  5. § Four months after stopping hormonal contraception, lesion #13 measured 1.34 × 1.27 × 0.69 cm in size (volume 0.61 cm3), consisting of a 37% volume reduction.
  6. £Five and one-half months after stopping hormonal contraception, lesion #14 measured 2.12 × 1.91 × 0.98 cm in size (volume 2.08 cm3), consisting of a 186% volume reduction.
