FIG 4. Data from a more aerobic node in patient 2.

A, T2-weighted image (3000/85/2) shows the location of the PRESS box.

B, Histogram of oxygen measurements. The median pO₂ value is 14.1 mm Hg, which is more aerobic than the median values for patients 1 and 7.

C, Uncoupled (Cycle 1 + Cycle 2).

D, Coupled (Cycle 1—Cycle 2).

E, Error spectra acquired with MRS parameters of 2000/144/256. The Cho:Cr ratio is 3.9.
