abstract = {Amide proton transfer (APT) and semi-solid magnetization
transfer (ssMT) imaging can predict clinical outcomes in
patients with glioma. However, the treatment of brain tumors
is accompanied by the deposition of blood products within
the tumor area in most cases. For this reason, the objective
was to assess whether the diagnostic interpretation of the
APT and ssMT is affected by methemoglobin (mHb) and
hemosiderin (Hs) depositions at the first follow-up MRI 4 to
6 weeks after the completion of radiotherapy. A total of 34
participants underwent APT and ssMT imaging by applying
reconstruction methods described by Zhou et al. (APTwasym),
Goerke et al. (MTRRexAPT and MTRRexMT) and Mehrabian et al.
(MTconst). Contrast-enhancing tumor (CE), whole tumor (WT),
mHb and Hs were segmented on contrast-enhanced T1wCE,
T2w-FLAIR, T1w and T2*w images. ROC-analysis, Kaplan-Meier
analysis and the log rank test were used to test for the
association of mean contrast values with therapy response
and overall survival (OS) before (WT and CE) and after
correcting tumor volumes for mHb and Hs (CEC and WTC). CEC
showed higher associations of the MTRRexMT with therapy
response (CE: AUC = 0.677, p = 0.081; CEC: AUC = 0.705, p =
0.044) and of the APTwasym with OS (CE: HR = 2.634, p =
0.040; CEC: HR = 2.240, p = 0.095). In contrast, WTC showed
a lower association of the APTwasym with survival (WT: HR =
2.304, p = 0.0849; WTC: HR = 2.990, p = 0.020). Overall, a
sophisticated correction for blood products did not
substantially influence the clinical performance of APT and
ssMT imaging in patients with glioma early after
radiotherapy.},
