Breast magnetic resonance imaging: kinetic curve assessment

The time-signal intensity curve (TIC) from dynamic contrast-enhanced magnetic resonance imaging (DCEMRI) reflects the hemodynamic features of a specific lesion. The TIC is obtained by repeated MRI scans after the injection of contrast agent; a qualified TIC usually takes 12 minutes to complete the scans. Temporal resolution is the main determinant; a higher temporal resolution means a smoother TIC.
