The purpose of this study was to assess
whether contrast-enhanced synthetic MRI is suitable for detecting brain metastases by
comparing the lesion-to-white matter contrast, contrast-to-noise ratio, and
number of brain metastases detected in synthetic and conventional magnetic
resonance images.
Synthetic T1IR images had better contrast
compared with synthetic T1W or conventional T1IR images. Synthetic T1IR images enabled detection of more metastases
than did synthetic T1W and conventional T1IR images even though statistical
significance was not detected.
Contrast-enhanced synthetic T1IR is useful
for detecting brain metastases.
Further optimization of contrast weighting
is needed to maximize the ability to detect brain metastases.
