Resource ImagingStudy - Content4.18
Manifest of a set of images produced in study. The set of images may include every image in the study, or it may be an incomplete sample, such as a list of key images.
The resource name as it appears in a RESTful URL is [root]/imagingstudy/
This resource summarises a series of images or other instances generated as part of an imaging study, and provides references to where the images are available using WADO-RS. This resource is used to make information concerning images etc. that are available in other clinical contexts such as diagnostic reports, Care Plans, etc. Also, see the use case description below.
This resources has been specifically designed with use in DICOM contexts in mind. The content is closely based on the definitions of the equivalent DICOM constructs, and informed by usage patterns already established through DICOM implementation practices, including XDS-I. It is not, however, necessary to use DICOM infrastructure in order to use this resource.

Use Case4.18.1.2
The following storyboard illustrates the primary use case for this resource:
An oncologist, Karen, is seeing patients in her clinic, and would like background on the patients she is seeing today. Her first patient of the day, Alex. has arrived. She launches her Electronic Medical Record (EMR) software, and makes a Patient query on Alex using his last name. The EMR software makes a FHIR query on the Patient resource, to provide background demographic information for cover page rendering. The EMR software makes a subsequent FHIR query on the Condition resource, and reports that Alex is suspected to have prostate cancer. With this information, Karen decides to check for two further tests - the results of a Prostate-Specific Antigen (PSA) laboratory test, and of a CT exam performed at the local diagnostic facility. First, a FHIR query is made against the Observation resource to query for the most recent value of PSA (the EMR also queries previous values of PSA for trending). For the CT exam, the EMR software queries on the ImagingStudy resource to retrieve a list of available images with other relevant constraints (such as modality, body region etc.). This returns back the studies available, with relevant meta-data about each study, its series and images. This information will help Karen to select which study would like to review. Using the WADO-RS references provided, the artifacts Karen would like to review can be downloaded and viewed using capable DICOM viewing software.
