The Short Axis slice review screen. The images are normalized using the "Region Scale" option--instead of normalizing to the hottest pixel, normalization at both stress and delay is to the most normal region at stress--- and presented for easy comparison between stress and rest to decide fixed versus reversible defect.The defect appears not to change in extent or severity between stress and rest.
The Vertical Long Axis slice review screen. The images are normalized properly ( IMAGE SCALE ) and presented for easy comparison between stress and rest to decide fixed versus reversible defect.
One of the output screens from INSPECTTM).The normal files (left column); the patient data (second column from left), the standard deviation map (second from right), and the patient data with abnormal area indicated by the yellow region ( at 2.5 S.D. from the normal file) are shown. Row 1 is the Stress data; Row 2 shows the Reinjection data while Row 3 shows the reversibility data.
Another screen from INSPECTTM shows the apical CAP(right column) at stress (top), rest(middle) and reversibility(bottom). The display shows clearly that the defect does not extend to the apex. Return to the
VLA display to confirm.
The "SMAP" screen map the defect region (yellow) and the normal region (white) from stress to rest ---the same regions. Then the ischemic zone (IZ) count in the yellow region are divided by the normal zone counts (white region) and compared stress versus rest to decide fixed versus reversible defect. IZ/NZ(=60% at stress) = IZ/NZ(=62% at rest), showing quantitatively that the defect is not reversible .
