>Scheduled Procedure Step Description | (0040,0007) | Institution-generated description or classification of the Scheduled Procedure Step to be performed. ### Note The purpose of this Attribute is to store a description or classification that is used at a local level (e.g., a hospital or a managed care network), and this description need not comply to an accepted standard.
>Scheduled Protocol Code Sequence | (0040,0008) | Sequence describing the Scheduled Protocol following a specified coding scheme. One or more Items shall be included in this Sequence.
>>Include Table 8.8-1 “Code Sequence Macro Attributes” | No Baseline CID is defined.
>>Protocol Context Sequence | (0040,0440) | Sequence that specifies the context for the Scheduled Protocol Code Sequence (0040,0008) Item. One or more Items shall be included in this Sequence. See Section C.4.10.1.
>>>Include Table 10-2 “Content Item Macro Attributes Description” | No Baseline TID is defined.
>>>Content Item Modifier Sequence | (0040,0441) | Sequence that specifies modifiers for a Protocol Context Content Item. One or more Items shall be included in this Sequence. See Section C.4.10.1.
>>>>Include Table 10-2 “Content Item Macro Attributes Description” | No Baseline TID is defined.
>Scheduled Procedure Step ID | (0040,0009) | Identifier that identifies the Scheduled Procedure Step.
>Scheduled Procedure Step Status | (0040,0020) | A Real World condition that may affect the selection of the Scheduled Procedure Step. Defined Terms: SCHEDULED Procedure Step scheduled ARRIVED Patient is available for the Scheduled Procedure Step READY all Patient and other necessary preparation for this step has been completed STARTED at least one Performed Procedure Step has been created that references this Scheduled Procedure Step DEPARTED Patient is no longer available for the Scheduled Procedure Step
>Comments on the Scheduled Procedure Step | (0040,0400) | User-defined comments on the Scheduled Procedure Step. ### Note The Comments Attribute is intended to transmit non-structured information, which can be displayed to the operator of the Modality.
>Modality | (0008,0060) | Source equipment for the image. See Section C.7.3.1.1.1 for Defined Terms.
>Requested Contrast Agent | (0032,1070) | Contrast agent requested for use in the Scheduled Procedure Step.
>Pre-Medication | (0040,0012) | Medication to be administered at the beginning of the Scheduled Procedure Step, e.g., Nuclear Medicine radiopharmaceutical.
>Anatomical Orientation Type | (0010,2210) | The anatomical orientation type appropriate for this Patient. Enumerated Values: BIPED QUADRUPED
Scheduled Specimen Sequence | (0040,0500) | Sequence of Items identifying specimens to be imaged in the identified Scheduled Procedure Step(s), with their characteristics.
>Include Table C.7.6.22-2 “Specimen Macro Attributes” |
Barcode Value | (2200,0005) | Barcode interpreted from a scanned label. ### Note In the case of a scanned patient label, this may be the same as Patient ID (0010,0020), but it is included in the Scheduled Procedure Step Module rather than the Patient Identification Module since barcodes may also be used to identify lower level entities and/or different forms of patient identifier may be in use. In the case of a scanned slide label, this may be the same as Container Identifier (0040,0512).

#### C.4.10.1 Protocol Context Sequence

The Protocol Context Sequence (0040,0440) allows the specification of parameters that further qualify the scheduled protocol, provided through a set of generic name/value pairs of context Content Items.

### Note

This allows the specification of clinical, acquisition, or procedural qualifiers for the scheduled protocol, such as a specific body part, imaging technique, or parameters of a preparatory event (e.g., radionuclide injection). Specific uses of this Sequence may be documented in a Template defined in accordance with PS3.16.
