The extension allows to extend the resources and feasibility analysis to NM data.
Context of Use
This extension may be used on the following element(s)
ImagingStudy.series
The NM (nuclear medicine imaging) extension enables the capture of relevant DICOM tags in order to draw conclusions about how the images were acquired. A characteristic of nuclear medicine is the use of a radiopharmaceutical consisting of a tracer and a radioisotope, which enables metabolic imaging. This information about the radiopharmaceutical is nested inside the DICOM tag RadiopharmaceuticalInformationSequence (0054,0016) — so-called nested DICOM tags.
Example of accessing a nested DICOM tag with Python from a DICOM slice (instance):
RadiopharmaceuticalStartTime = layer['RadiopharmaceuticalInformationSequence'][0]['RadiopharmaceuticalStartTime'].value
Implementation:
Radiopharmaceutical (ValueSet with codes: https://dicom.nema.org/medical/dicom/current/output/chtml/part16/sect_CID_25.html): The radiopharmaceutical can be converted from its code to the display name by resolving the code at "0054,0016" (Radiopharmaceutical Information Sequence) → "0054,0304" (Radiopharmaceutical Code Sequence) → "0008,0100" (Code Value). If this is not present, the value can be extracted directly from the tag "0054,0016" (Radiopharmaceutical Information Sequence) → "0054,0304" (Radiopharmaceutical Code Sequence) → "0008,0104" (Code Meaning). If the display name differs from the ValueSet, a local mapping can be established at the site. If it is still missing, the tag "0054,0016" (Radiopharmaceutical Information Sequence) → "0018,0031" (Radiopharmaceutical) can additionally be consulted — please use it only if the string consistently contains BOTH the tracer AND the radionuclide (see the ValueSet link).
Tracer exposure time: This is a custom tag and is calculated as the difference in seconds between the Acquisition Time "0008,0032" (or similar) and "0054,0016" (Radiopharmaceutical Information Sequence) → "0018, 1072" RadiopharmaceuticalStartTime.
Half-life ["0018, 1075" RadionuclideHalfLife] in seconds [s]
Total radionuclide dose ["0018, 1074" RadionuclideTotalDose] in megabecquerel [MBq] (note: for PT, the unit Bq is normally used instead!)
Examples
Note: For clarity, this example does not include all of the associated series and instances. In a real implementation, all series and instances belonging to the study are of course expected to be present in the resulting FHIR resource — the "series" or "instance" sequence is simply repeated for every series or instance and filled with the corresponding values.
Example of an ImagingStudy resource with the extension for NM metadata, including the modality-independent extensions for contrast media, instance details and device manufacturer:
