CP-1764More quantitative image featuresStatusFinal TextDate of Last Update2019/01/21Person AssignedDavid ClunieSubmitter NameQIICRSubmission Date2017/12/03Correction Number CP-1764Log Summary: More quantitative image featuresName of StandardPS3.6, PS3.16Rationale for Correction:CP 1705 added codes for a comprehensive set of texture features, but more features can be extracted from images than are currently included in DICOM.This CP includes revisions to how to encode features, what features are available, and the description of certain aspects of how they are derived (which affect their interpretation/repeatibility).Now that IBSI defines its own codes, some DCM codes are no longer necessary and are retired with reference to the IBSI codes. IBSI is added as a coding scheme. Also add the Radiomics Ontology (RO) as a coding scheme.An example of usage of a broad range of radiomic features, without reference to standard definitions and highlighting the need for them, is found in Kalpathy-Cramer J et al. Radiomics of Lung Nodules: A Multi-Institutional Study of Robustness and Agreement of Quantitative Imaging Features. Tomography. 2016 Dec;2(4):430–7. .]The proposed quantitative image features context group includes generic size and intensity measurements and hence the measurement parameters invoked in TID 1500 are simplified. The title of the the context group is "quantitative image features" rather than "radiomics" since these have more general applications than just radiology.

Content Item DescriptionsRows 7, 8, 9The baseline context groups defined allows for generic intensity, size and, texture and other feature 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.Equation or TableResources:

(126326, DCM, "IAUC90BN") can be used for DCE-MRI using a Gd-based contrast agent to represent the IAUGCBN measurement in the claim of the QIBA DCE MRI Quantification Profile, though the concept itself is not specific to the modality or the contast agent used. See . See also Ng, CS., et al. "Reproducibility of Perfusion Parameters in Dynamic Contrast-Enhanced MRI of Lung and Liver Tumors: Effect on Estimates of Patient Sample Size in Clinical Trials and on Individual Patient Responses." AJR 194, no. 2 (February 1, 2010): W134–40. .The type of contrast agent and the AIF used for blood normalization may or may not be post-coordinated.E.g., voxel-wise IAUCBN measurements encoded as a parametric map with the quantity defined by the Quantity Definition Sequence (0040,9220) in a Real World Value Map might be encoded as:
(G-C1C6, SRT, "Quantity") = (126326, DCM, "IAUC90BN")
(G-C036, SRT, "Measurement Method") = (126362, DCM, "User-defined AIF ROI")
(123011, DCM, "Contrast Bolus/Agent") = (C-17800, SRT, "Gadolinium")
E.g., an IAUCBN measurement for an ROI encoded in a structured report might be encoded as:NUM (126326, DCM, "IAUC90BN") = 0.230 (UNITS = ({normalized}, UCUM, "normalized")>HAS CONCEPT MOD: CODE (G-C036, SRT, "Measurement Method") = (126364, DCM, "Blind Estimation of AIF")
Note that the generic ROI measurement templates do not have the contrast/bolus agent as a parameter; this may be implicit from context, or inherited from the (121058, DCM,"Procedure reported") in the parent template.MR Proton Spectroscopy MetabolitesResources:

For the purpose of this context group, where possible, the resonance peak in the spectrum corresponding to a particular metabolite is described using the concept from SNOMED for the substance corresponding to the metabolite. E.g., the code used for "lipid" is the code for "lipid (substance) ", as this concept is effectively post-coordinated by its use in the Metabolite Map Code Sequence (0018,9083) to mean "lipid resonance peaks in MR spectroscopy".Radiation Dose TypesResources:
