Extension Modalität PET und Nuklearmedizin

Die Extension PT & NM (PET und Nuklearmedizinische Bildgebung) ermöglicht das Erfassen relevanter DICOM-Tags, um Rückschlüsse über die Bildgewinnung ziehen zu können. Eine Besonderheit der Nuklearmedizin ist die Verwendung eines Radiopharmakons, das aus einem Tracer und einem Radioisotop besteht und somit Stoffwechselbildgebung ermöglicht. Diese Informationen über das Radiopharmakon liegen verschachtelt in dem DICOM-Tag RadiopharmaceuticalInformationSequence (0054,0016) vor, sogenannte nested DICOM-Tags.

Diese nested DICOM-Tags sind:

Radiopharmakon [(0054, 0304) RadiopharmaceuticalCodeSequence]
Applikationsstartzeit [(0018, 1072) RadiopharmaceuticalStartTime]
Halbwertszeit [(0018, 1075) RadionuclideHalfLife] in Sekunden [s]
Gesamte Radionukliddosis [(0018, 1074) RadionuclideTotalDose] in Megabecquerel [MBq] <-Nicht konsistent zwischen PET & Nuklearmedizin und unter Umständen zwischen Standorten. Angaben in MBq sind normalerweise 1- bis 5-stellig. Ist die Angabe um den Faktor 10⁶ höher, also 7- bis 12-stellig, handelt es sich um die Radionuklid-Totaldosis in Bq, und sie muss entsprechend umgerechnet werden.

Nicht nested DICOM-Tags:

ReskalierungsTyp [(0028,1054) RescaleType]

The value includes an implicit precision in the presentation of the value. Requirements Precision is handled implicitly in almost all cases of measurement. Comments The implicit precision in the value should always be honored. Monetary values have their own rules for handling precision (refer to standard accounting text books). Data type decimal Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` Mappings rim: n/a v2: SN.2 / CQ - N/A rim: PQ.value, CO.value, MO.value, IVL.high or IVL.low depending on the value
comparator	Σ ?!	0..0	codeBinding	There are no (further) constraints on this element Element id Extension.extension:radionuclideHalfLife.value[x].comparator Short description < \| <= \| >= \| > - how to understand the value Definition Not allowed to be used in this context Requirements Need a framework for handling measures where the value is <5ug/L or >400mg/L due to the limitations of measuring methodology. Comments Note that FHIR strings SHALL NOT exceed 1MB in size Meaning when missing If there is no comparator, then there is no modification of the value Data type code Binding How the Quantity should be understood and represented. QuantityComparator (required) Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` Mappings rim: n/a v2: SN.1 / CQ.1 rim: IVL properties
unit	Σ	0..1	stringPattern	Element id Extension.extension:radionuclideHalfLife.value[x].unit Short description Unit representation Definition A human-readable form of the unit. Requirements There are many representations for units of measure and in many contexts, particular representations are fixed and required. I.e. mcg for micrograms. Comments Note that FHIR strings SHALL NOT exceed 1MB in size Data type string Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` Pattern Seconds Mappings rim: n/a v2: (see OBX.6 etc.) / CQ.2 rim: PQ.unit
system	Σ I	0..1	uriPattern	Element id Extension.extension:radionuclideHalfLife.value[x].system Short description System that defines coded unit form Definition The identification of the system that provides the coded form of the unit. Requirements Need to know the system that defines the coded form of the unit. Comments see http://en.wikipedia.org/wiki/Uniform_resource_identifier Data type uri Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` Pattern http://unitsofmeasure.org Mappings rim: n/a v2: (see OBX.6 etc.) / CQ.2 rim: CO.codeSystem, PQ.translation.codeSystem
code	Σ	0..1	codePattern	Element id Extension.extension:radionuclideHalfLife.value[x].code Short description Coded form of the unit Definition A computer processable form of the unit in some unit representation system. Requirements Need a computable form of the unit that is fixed across all forms. UCUM provides this for quantities, but SNOMED CT provides many units of interest. Comments The preferred system is UCUM, but SNOMED CT can also be used (for customary units) or ISO 4217 for currency. The context of use may additionally require a code from a particular system. Data type code Constraints ele-1: All FHIR elements must have a @value or children `hasValue() or (children().count() > id.count())` Pattern s Mappings rim: n/a v2: (see OBX.6 etc.) / CQ.2 rim: PQ.code, MO.currency, PQ.translation.code
url		1..1	uriFixed Value	Element id Extension.url Short description identifies the meaning of the extension Definition Source of the definition for the extension code - a logical name or a URL. Comments The definition may point directly to a computable or human-readable definition of the extensibility codes, or it may be a logical URI as declared in some other specification. The definition SHALL be a URI for the Structure Definition defining the extension. Data type uri Fixed value https://www.medizininformatik-initiative.de/fhir/ext/modul-bildgebung/StructureDefinition/mii-ex-bildgebung-modalitaet-pt-nm Mappings rim: N/A
value[x]		0..0		There are no (further) constraints on this element Element id Extension.value[x] Short description Value of extension Definition Value of extension - must be one of a constrained set of the data types (see Extensibility for a list).

Hinweis
	Aus Gründen der Übersichtlichkeit wurde in diesem Beispiel darauf verzichtet, alle dazugehörigen Serien bzw. Instanzen mit einzubinden. Natürlich ist es bei der Implkementierung vorgesehen, dass alle zur jeweiligen Studie gehörenden Serien und Instanzen auch in der resultierenden FHIR-Ressource enthalten sind - dafür wird dann einfach die Sequenz "series" bzw "instance" für jede Serie bzw. Instanz wiederholt und mit den entsprechenden Werten befüllt.
