Figure 1

Example of a 90 Y PET/ CT phantom scan with maximum intensity projection image. (a) Trans-axial, (b) coronal, and (c) sagittal planes. This scan shows our lowest tested vial sediment activity of 3.5 MBq (≈3 MBq/ml). The upper PET visual display threshold of this scan was adjusted to 114% (2,000 kBq/ml) to minimize visual interference from background noise [1]. (d) Maximum intensity projection image of the same phantom scan (arrow indicates vial sediment) with the upper PET visual display threshold adjusted to 1% (20 kBq/ml) to reveal the underlying background noise as an example to readers [1].
