Note a recent survey that confirms users preference for separating "measurements" from other findings in reports (<link xl:href="http://www.academicradiology.org/article/S1076-6332%2814%2900087-7/abstract" >Travis et al. Preferences for Structured Reporting of Measurement Data</link>).</para> <para>Simple measurements (like distance) are also needed in addition to planar and volumetric ROIs, so TID 300 Measurement has also been included (in preference to more specific templates like TID 1400 Linear Measurement, which lack the general mechanism for including modifiers to define site, method, etc.).</para><para>Since a single ROI often has multiple measurements associated with it, the ROI measurement template (TID 1419) is refactored to allow specific modifiers to be present at a common as well as per-measurement level, and in particular the finding site and measurement method. In allowing this, it is apparent that the "1-n" cardinality should not be permit both on the inclusion of TID 1419 as well as the (formerly first) NUM content item of TID 1419, and so the former is restricted to 1.</para> <para>A mechanism has been added for including simple coded or text qualitative evaluations either at the top (subject) level or with each measurement group, since it is common to gather such information whilst making measurements.</para> <para>Time point information is optionally included at the measurement group level, allowing for recording the time point without constraining the scope of a single report instance to being one time point or multiple.</para> <para>An informative section is added to PS 3.17 to illustrate use of the templates.</para> <para>In future, the parameters passed to the subordinate templates may define specific regions and types of measurements, and context groups can be defined for those if necessary (e.g., a set of SUV and related PET measurements on FDG or FLT PET, for instance, or DCE-MRI measurements). The intent of this generic root template is not to preclude the future definition of more specific templates that specialize it for very specific purposes, which could retain the same structure but constrain the sets of values, and add other content (such as a description of the procedure reported, +/- references, e.g., to specific types of images (like T1 maps and dynamic T1 images for DCE-MRI, for instance).</para> <para>Also, the list of quantitative procedures reported is expected to be expanded in future. LOINC is lacking a lot of specific variants of procedures (e.g., FLT versus FDG whole body PET, DCE of prostate, etc.). SNOMED has slightly better coverage of PET, and has very patchy coverage of dynamic MR (pelvis and knee only). RadLex doesn't have DCE-MR (or any "dynamic" concepts, though there is "perfusion" for CT and NM only); it does have PET (modeled in a really weird way that makes it hard to find, as an NM modality with a technique of "PET" or "CT-PET"). Furture research applications probably need specific codes, and non-oncology apps like neuro and MSK will probably need newly procedures like Amyloid PET as well as structural MR (e.g., for hippocampal volume).</para> <para>There is a balance needed (and potentially some redundancy) between the codes used for the Document Title (top level container) and the Procedure Reported, but these are kept distinct in order to handle a measurement-specific report created for standard of care images (e.g., oncology measurements on ordinary chest/abdomen/pelvis CT). There is a subtle difference between the imaging acquisition procedure reported, and the act of making the measurement, which is often performed separately; for arguments sake, this proposal assumes that the Procedure Reported is the acquisition procedure, and it turns out that the definition is lacking in DICOM, so one is added here.</para> </td> </tr> <tr> <td rowspan="1" colspan="1" valign="top"> <para>Editor's Notes:</para> <para>Rows will be appropriately renumbered at final text or incorporation into the standard.</para> </td> </tr> <tr> <td rowspan="1" colspan="1" valign="top">Correction Wording:</td> </tr> </informaltable> </chapter> <chapter> <title/> <section> <title/> <informaltable rules="all" frame="box"> <tr> <td> <para><emphasis role="italic">Amend DICOM PS 3.16 - Content Mapping Resource - Structured Reporting Templates to add the following:</emphasis></para> </td> </tr> </informaltable> <section label="TID t1tt1" status="3" xml:id="sect_TID_t1tt1"> <title>Measurement Report This root template that encodes a list of Measurement Groups each containing lists of measurements, together with any derived measurements.

Content Item Descriptions Rows 6, 10, 12 The conditions require that all except one of the "heading" containers is present, though each may be empty. Rows 7, 8, 9 The baseline context groups defined allow for generic intensity and size measurements, regardless of the geometry of the ROI (e.g., linear distance can be measured on volumes, or volume can be estimated from a linear distance), and being baseline, do not constrain the invoker from using other appropriate concepts specific to the application. Row 9 A Measurement Group is used to contain one or more individual measurements that are invocations of TID 300, consistent with TIDs 1410 and 1411, which both already have Measurement Group containers as their roots. Rows 12, 13, 14 These content items allow encoding a flat list of name-value pairs that are coded questions with coded or text answers, for example, to record categorical observations related to the entire subject of the report rather than specific measurement groups. ...
Measurement Group This template groups Measurements into a Measurement Group. Each Measurement Group is identified by Tracking ID and UIDs, and may be described as having being made at a particular time point. Measurement groups may contain various common measurement modifiers that are shared by all measurements in the group, such as method and finding site.

Content Item Descriptions Rows 2, 3, 10 The included TID 300 already contains an optional inclusion of TID 1408 Tracking Identifier, which in turns allows for either or both Tracking Identifier and Tracking Unique Identifier content items; the intent of Rows 2 and 3 is not to send these content items twice, but rather to specialize their use such that their presence is mandatory, consistent with TIDs 1410 and 1411. Row 9 The reference to an RWV in Row 9 allows measurements to be made in units that differ from the stored pixel values in the images referenced elsewhere in the template. E.g., for a PET SUVbw measurement, the mapping from activity/concentration units in the referenced image that was used (and which may be reused for measurements in the future) may be encoded in a referenced RWV instance. This reference applies to any measurements in included templates, unless overridden). Rows 11, 12 Allows encoding a flat list of name-value pairs that are coded questions with coded or text answers, for example, to record categorical observations related to the subject of the measurement group. ...

Content Item Descriptions Row 1 Usually the same value as the Clinical Trial Time Point ID (0012,0050) attribute in the Clinical Trial Study Module, though not confined to clinical trial use. May or may not be human readable, and not required to be a DICOM UID. Row 2 All of the subjects within a treatment protocol that are examined at a particular scheduled time point (e.g., "baseline", "pre-treatment", "first post-treatment") will have the same Protocol Time Point Identifier, but different Subject Time Point Identifiers. However, in different protocols, the Protocol Time Point Identifiers for the same conceptual “time point” will be different. E.g., the “baseline” time point will have different Protocol Time Point Identifiers in different protocols. May or may not be human readable, and not required to be a DICOM UID. Row 3 Typically a short pre-defined label that has the same scope as Protocol Time Point Identifier (i.e., same conceptual time point within a treatment protocol) but is human-readable and understandable, e.g., "BASELINE" or "TP0", "TP1", etc. Usually the same value as Clinical Trial Time Point Description (0012,0051) attribute in the Clinical Trial Study Module, though not confined to clinical trial use. The Concept Name is selected as (C2348792, UMLS, "Time Point") (which is (C68568, NCIt, "Time Point"), defined as "a specific point in the time continuum, including those established relative to an event") in order to be compatible with external terminologies. Row 4 More than one type is permitted, e.g., a time point may be "posttreatment" as well as "unscheduled" or "nadir", etc. Row 5 The order is expected to be monotonically increasing within a particular scope of usage, but is not required to start at 0 or 1, nor required to increase in increments of 1 or even the same increment (e.g., to allow for retrospective insertion of unscheduled time points). In clinical usage, the Time Point Order would be expected to be temporally increasing, but in a clinical trial may be a randomized reading order rather than a temporal order. ...

Measurement Report SR Document Volumetric ROI on CT Example This CT example describes the minimum content necessary to encode a single measurement (volume) made from a single volumetric ROI encoded as a single segment that spans two source CT images. References to Segmentation Image or Surface Segmentation objects are encoded as IMAGE references, with a single value specified in Referenced Segment Number. The method of volume calculation is not described in this example.

Measurement Report SR Document Volumetric ROI on CT Example This CT example describes a set of measurements (volume. long axis and mean attenuation coefficient) made from a single volumetric ROI encoded as a single segment that spans two source CT images, and includes a description of the measurement methods and the finding site, as well as an image library to describe characteristics of the images used, and categorical observations at the measurement group and entire subject level. For a different modality than CT, the choice of measurement for the mean intensity would not be (122713, DCM, "Attenuation Coefficient"). For MR one might use (110852, DCM, "MR signal intensity"), or (110804, DCM, "T1 Weighted MR Signal Intensity"), etc. See also CID 7180 "Abstract Multi-dimensional Image Model Component Semantics" for various appropriate signal intensity types for MR and other modalities. For PET one might use (110821, DCM, "Nuclear Medicine Tomographic Activity"), in which case the specific type of signal would be apparent from the units, e.g. ({SUVbw}g/ml, UCUM, "Standardized Uptake Value body weight") or for activity-concentration, (Bq/ml, UCUM, "Becquerels/milliliter"). See also CID 84 PET Units For Real World Value Mapping. Care should be taken when selecting modifiers such as (G-C036, SRT, "Measurement Method") versus (121401, DCM, "Derivation"). The finding site and laterality within the measurement template (TID 1419) are factored out and shared by both measurements. The pattern used for the image library uses TID 4020, though commonality may be refactored (in a separate CP).
