CP-1764 More radiomic features Status Assigned Date of Last Update 2017/12/22 Person Assigned David Clunie Submitter Name QIICR Submission Date 2017/12/03 Correction Number CP-1764 Log Summary: More radiomic features Name of Standard PS3.16 Rationale for Correction: CP 1705 added codes for a comprehensive set of texture features, but more radiomic features exist than are currently defined in the DICOM standard. A comprehensive example of usage 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 radiomic features context group includes generic size and intensity measurements and hence the measurement parameter invoked in TID 1500 are simplified. [Ed.Note.: Add Law's texture features.] [Ed.Note.: Add local and global shape descriptor concepts. ? reference] Correction Wording: <informaltable rules="all" frame="box"> <tr> <td> <para><emphasis role="italic">Amend DICOM PS3.16 as follows (changes to existing text are bold and <emphasis role="bold"><emphasis role="underline">underlined</emphasis></emphasis> for additions and <emphasis role="bold"><emphasis role="strikethrough">struckthrough</emphasis></emphasis> for removals):</emphasis></para> </td> </tr> </informaltable> <section label="TID 1500" status="3" xml:id="sect_TID_1500"> <title>Measurement Report

Content Item Descriptions Rows 7, 8, 9 The baseline context groups defined allow for generic intensity and, size and texture 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.

(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.

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".
