Schematic of the interleaved acquisition with example simulated AIF and three tumor curve types. The solid lines represent the simulated time series (without gaps or noise) and the marker points illustrate the data acquired with the interleaved technique (with noise). Red and blue segments represent high spatial resolution (HSR) and high temporal resolution (HTR) acquisitions, respectively. At the first burst of HTR imaging (segment A) 36 volumes were acquired for method 2, to encompass the first two passes of the contrast agent bolus. For method 3, this was reduced to 21 volumes (acquisition stops at the dotted line) to exclude the 2nd pass of the AIF. During the following bursts (segments B, C and D) 16 time points were acquired, each segment occupying the acquisition time of a single HSR volume. There were eight HSR volumes acquired in total.
