Grey/white matter contrast (upper panel), spatial resolution assessed through a sharpness index (middle panel), and relative noise (lower panel), obtained for peripheral (occipital cortex, dark grey columns), central grey matter (striata, light grey columns), and white matter structures (semi-oval centers, white columns) on the SPECT images of phantom (left panel) and patients (box-plots, right panel) with conventional Anger camera (left columns) and with full-time (median columns) and half-time (right columns) recordings from the CZT camera. p values significant in clinical study are indicated on the figure
