2.2 MRI Params
2.2.1 Phase
00089209
(0008,9209): Acquisition Contrast
Example:
"00089209": {
"vr": "CS",
"Value": [
"T2"
], }
2.2.2 Slice Thickness & Gap
\[ \text{Slice Gap} = (\text{Spacing Between Slices}) − (\text{Slice Thickness}) \]
(0018,0050): Slice Thickness
(0018,0088): Spacing Between Slices
2.2.2.1 Alternative
If Spacing Between Slices is missing, slice positions from the:
(0020,0032): Image Position (Patient)
Can be used to derive the slice gap indirectly by comparing the Z-coordinates of consecutive slices.
