Technologist and Radiologist Technologist and Radiologist Communication Profile RationalCommunication Profile Rational
Currently, technologists cannot see markups in the acquisition room that radiologist applies to images at the diagnostic workstation unless special hardware is purchased and placed in the acquisition room.
5
Technologist and Radiologist Technologist and Radiologist Communication – Use Case 1Communication – Use Case 1
Radiologist decides that extra views are necessary on a patient while reading a mammogram.
The radiologist applies text and or graphic markups on the images to indicate the location of the potential lesion and to indicate which additional views to perform.
The technologist opens the case with the markups, reviews the images and performs the requested additional views.
6
Technologist and Radiologist Technologist and Radiologist Communication – Use Case 2Communication – Use Case 2
While performing a mammogram, the technologist has a question that requires input from the radiologist prior to the patient leaving the acquisition room.
The tech applies text and or graphic markup to the images.
The radiologist reviews the images and markups and gives instructions to the tech as to how to finish the study.

IHE Reporting 2.0IHE Reporting 2.0 Issue/current state: there are a multitude of encodings, transport
mechanisms and applications/use cases for each of the different types of data in the reporting chain
Key points to address:• What are recommended/permitted/deprecated encodings for each
type of data• What are recommended/permitted/deprecated transport mechanisms
for each type of data• When/where are encoding translations and/or transport bridges
appropriate/inappropriate Have created a reporting task force that crosses domains, though need
more participation from most outside domains Objective for this year is to research and produce a whitepaper Depending on progress and ability to achieve consensus, the objective
for next year or the following would be a scoped profile proposal

IHE Reporting 2.0IHE Reporting 2.0 - Content - Content Proposal will need to allow for a phased progression – practical for today yet
providing the guidance and flexibility for the future
3 - Text snippets: Reason = blah, Diagnosis = blah,
4 - Coded: Reason = x12, Diagnosis = y43, Finding1 = ... Current high level thoughts:
• DICOM SR within department: Evidence Documents like Key Image Notes• HL7 CDA once leave the department• Remaining question of what actor performs the translation, when, and where
in the workflow Have only scratched the surface – still need to take into account the existing
combinations that are being used as well as many more peripheral use cases (e.g. quality measures, data mining, publishing to national registry, etc.)
Templates will be developed for the conversion between SR and CDA

Radiology Reporting WorkflowRadiology Reporting WorkflowThe Current Reporting Workflow (RWF) and Post Processing Workflow (PWF) will be Simplified and optimize.
The new DICOM Supplement 96, “Undefined Worklist and Procedure Step” will be used to simplify the Reporting Workflow Management, and support both the Push and Pull models Workflow. Which means that the Reporting work items will be accessible in both methods: either by Pushing the work items from the Workflow Manager to the Workstations or Pulling the work items by the Radiologist from the Workflow Manager Worklist.

National Extensions: CanadaNational Extensions: Canada Extended DICOM Character Sets - The Specific Character Set (0008,0005) Attribute shall contain the value “ISO_IR 100” in order to select ISO 8859/1 Latin-1 characters.
Extended HL7 Character Set - The Field MSH 18 shall contain the value “8859/1” in order to select the ISO 8859 Latin-1
Public health identifier (PHI) – In HL7 should be located in PID-3 and in DICOM it should be located in the tag (0010,1000).
Extension and Translations of Physician Types in PV1
PV1-19 (Visit Number) is an identifier for the visit or consult episode.
The 'D’ value, should be added to the PV1-2 (Patient Class) for Day hospitalization.
Extend the PID-16 (Marital Status), adding the G for Living Together in the Marital Status table.
Syntax Rules for PID-5 (Patient Name) - Last name prefix will be used for names with « particule ».
Translation of Specific Fields of the PID Segment

National Extensions: SpainNational Extensions: SpainSupport the Character set for ISO Latin 1
Patient Identification – Use 2 Family names
Patient Insurance Status
Patient Contact data: Mail, Email, Phone,..

National Extensions: JapanNational Extensions: Japan More detailed order information is needed Patient arrival is important event Support for medical billing system is required Extension for SWF and CHG integration profiles
Proposed 2 New Transactions- Patient Accepted/Arrival Notification [RAD-X], using HL7 ORU message - Order Performed Notification [RAD-Y], using HL7 OMI message for Billing
purposes
Affected Existing Transactions- Register Patient [RAD-1] & Patient Update [RAD-12]– Utilize only A08 event.- Placer Order Management [RAD-2] – HL7 OMG message is used instead of
ORM. Detail information is set in ORC segment by using JJ1017 Code - Filler Order Management [RAD-3] become optional and can be substituted by the
new transaction: Order Performed Notification [RAD-Y]- Procedure Scheduled [RAD-4] – HL7 OMI message is used from DSS/OF to
IM/RM, ORI used for reply from IM/RM to DSS/OF and ORM message is not being used
- Procedure Update [RAD-13] – HL7 ORM message is not used.
