Description |
| (0018,9117) | MR Diffusion Sequence | 1 | Identifies the diffusion parameters of this frame. One Item shall be included in this sequence. |
| (0018,9087) | >Diffusion b-value | 1C | Diffusion sensitization factor in sec/mm 2 . This is the actual b-value for original frames and those derived from frames with the same b-value, or the most representative b-value when derived from images with different b-values. Required if Frame Type (0008,9007) Value 1 of this frame is ORIGINAL. May be present otherwise. |
| (0018,9075) | >Diffusion Directionality | 1C | Specifies whether diffusion conditions for the frame are directional, or isotropic with respect to direction. Defined Terms: DIRECTIONAL ISOTROPIC NONE = to be used when Frame Type (0008,9007) value 4 equals DIFFUSION_ANISO or Diffusion b-value (0018,9087) is 0 (zero). Required if Frame Type (0008,9007) Value 1 of this frame is ORIGINAL. May be present otherwise. |
| (0018,9076) | >Diffusion Gradient Direction Sequence | 1C | Sequence containing orientations of all diffusion sensitization gradients that were applied during the preparation phase for this frame. Required if Diffusion Directionality (0018,9075) equals DIRECTIONAL |
| (0018,9089) | >>Diffusion Gradient Orientation | 1C | The direction cosines of the diffusion gradient vector with respect to the patient Required if Frame Type (0008,9007) Value 1 of this frame is ORIGINAL. May be present otherwise. |
| (0018,9147) | >Diffusion Anisotropy Type | 1C | Class of diffusion anisotropy calculation. Defined Terms: FRACTIONAL RELATIVE VOLUME_RATIO Required if Frame Type (0008,9007) value 4 equals DIFFUSION_ANISO. |
