In order to investigate the representation of complex
tumors when using modern, view sharing MRI sequences
such as TWIST, dynamic contrast-enhanced TWIST raw data
were generated from static background and a fractal
tumor phantom raw data scaled with an enhancement model.
Our results show that, for typical spatial resolution in
clinical breast DCE-MRI, TWIST parameters of pA=20%-25%
and pB=33% provided an enhancement measurement with
lowest RMS error. The measured shape irregularity of the
tumor changed in a less predictable way, however, which
should be taken into consideration in the texture
analysis of the images.
