1 About cvi42|Report
cvi42|Report is designed to facilitate documentation and reporting of cardiac images. Fields with import function and with calculation algorithms allow for a fast and easy transition from quantitative information such as volumetric and signal intensity data to a structured report. cvi42|Report is based on societal recommendations on structured reporting for cardiovascular imaging (Douglas et al., Journal of the American College of Cardiology 2009;53:76-90.) and can be integrated into patient information storage systems.
When linked with cvi42|Report®, it automatically imports image analysis results and classifies them based on user-editable normal value sets. Standard phrases can be defined for preparing the report. A graphical interface allows for using mouse-clicks to verify regional function tissue pathology and grade stenoses. Results are automatically translated into a narrated findings summary, but includes a graphic presentation of the results.
2 Intended Use
cvi42|Report is a web browser-based networked software application intended to use for reporting the results of the cardiovascular MR or CT image analysis performed with a post processing software application or PACS (Picture Archive Communication System) and RIS (Radiology Information System). It can be used as a standalone reporting software application by manually entering necessary information.
cvi42|Report shall only be used to report the Cardiovascular Magnetic Resonance Image analysis or Computed Tomography analysis.
cvi42|Report is not a diagnostic software application.
Please note that the users of cvi42|Report shall review the contents for accuracy prior to releasing the report.

3.8 How to Tag a Report
Every report page has a section for adding and removing new tags. Tags are short metadata descriptions of the qualities of a report that can assist in future searches, but do not print on the final report.
Tags could describe patient conditions, actions taken in the study, study status, ownership, or anything else that isn't directly searchable in a typical field. For example:
- needs review
- sent to referrer
Tags can be added to a study and created as you work by using the Plus icon in the Tags section.
Access to the Administrative section of cvi42|Report is limited by a user's Role and the corresponding Permissions.
cvi42|Report allows you to define multiple user and roles. You can Add a new user or Edit existing users.
Note: By default, cvi42|Report is configured to allow user and role management to take place entirely in cvi42|Report v5.5+. If cvi42|Report meets the minimum required version, you can do all of your user and role administration there. User details will automatically be synchronized to cvi42|Report when that user signs in, and their password will always be managed in cvi42|Report.
It is possible to link older local cvi42|Report accounts to cvi42|Report so that all user management will take place in cvi42|Report. It is also possible to have a mix of local cvi42|Report-only users and users managed by cvi42|Report.
The link icon indicates that a user is sourced and managed from cvi42|Report.
Users sourced from cvi42|Report do not need to be added manually, they will appear in this list as they log in using their cvi42|Report credentials and will be granted the same roles.
A user is able to interact with the system in different ways, depending on what roles they are assigned. The following matrix shows which of the default roles can access which features and administrative sections:

4.1.4 Disease Clusters, Indications, and Protocols
Indication Driven Workflow was introduced in cvi42|Report version 5.6. For implementations using this workflow, the configuration of disease clusters, indications, protocols, and sequences is managed in cvi42|Report, so cvi42|Report will display the following message:
For implementations not using the indication driven workflow, disease clusters, indications and protocols are managed in cvi/span>42|Report. cvi/span>42|Report comes with a predefined disease, indication, and protocol hierarchy. To edit, go to their respective Admin sections.
184.108.40.206 Desease Clusters
Use the Desease Clusters section to view, add, or edit disease clusters.
Use the Indications section to view, add, or edit indications or
to assign them to a disease cluster.
Link an Indication to a Disease Cluster
After saving, use Ischemic HD checkboxes to select the

4.1.5 PACS configuration
Here you may configure the DICOM PACS entities that cvi/span>42|Report may send reports to, as well as the method of packaging reports as DICOM data.
AE Title: the Application Entity Title that cvi/span>42|Report
should use when communicating with a PACS.
- Note: Your PACS Administrator or PACS Vendor must configure your PACS to accept images from this AE-Title and the cvi/span>42|Report server/host IP Address.
- Minimum State for DICOM Reporting: Allows you to restrict the state that a report must reach before being permitted to send report data to PACS (default: Finalized).
220.127.116.11 Adding and Editing PACS configuration
Use the Add New StoreSCU button to add a new PACS host to receive DICOM reports, or edit an existing host conifguration using the Pencil icon.
- Host Name: network host name or IP address of the PACS that will receive DICOM reports.
- AE Title: the Application Entity Title to target when sending data to this DICOM PACS node.
- Port: the TCP port that the PACS with this AE Title listens on.
- Description: a description of this PACS that the user will see when selecting from multiple PACS. This can be more descriptive than the AE Title or hostname, such as, "Clinical", "Research", "Radiology", "Cardiology", etc.
- Parameters: optional parameters suitable for DCMTK's storescu command. Only required for advanced tuning.
DICOM File Type: Choose the type of DICOM report that this
PACS will accept.
- A Secondary Image Capture Series is most commonly supported. The transfer syntax and resolution are configurable according to your PACS DICOM Conformance Statement. Exceeding 300dpi is not recommended due to higher rendering time and storage requirements.
- DICOM Encapsulated PDFs may be used if they are supported by your PACS and PACS Viewer. Generally this option yeilds the highest resolution and smallest data size, but is relatively rare.
- Test (C-ECHO): Sends a DICOM C-ECHO message to your PACS and displays the result. This is useful to confirm that the configuration is correct on the PACS and on this cvi/span>42|Report instance.
Here you may search through the audit log for changes to the system and edits to report contents.
Here you may add and edit report tags for use by all users or by users having specific roles. Tags are short metadata descriptions of the qualities of a report that can assist in future searches, but do not print on the final report.
Tags could describe patient conditions, actions taken in the study, study status, ownership, or anything else that isn't directly searchable in a typical field.
Tags created for a user's personal use can only be edited by them in their user user profile page, accessible from the link (their full name) in the top-right of the cvi/span>42|Report web page.
4.2 Report Content
4.2.1 Site of Service
The Site of Service information appears at the top of the first page of your report.
Here you can enter contact and accreditation information for your facility, as well as a logo. Logos can be quite large in terms of resolution (which will look sharper on printed reports), However you are advised to use a logo which is approximately square or roughly 2:3 (height:width) in dimension.
The Staff module allows you to define the list of people who operate your facility and participate in studies. These people can be added to a report in the Edit Exam page. Their names and all identifying information will appear on the exported reports. Staff are not necessarily users of cvi/span>42|Report and are not granted access to the system. Refer to the Users module.
When editing staff, there are two options for the Type of Change:
- Updated Staff Profile: The old staff information (name, position, etc.) will be retained for existing reports, and this edited information will be used for old reports. This can be done many times, for example if a staff member changes their job title.
- Correction: Simply corrects the current record, for example if the staff person's name was misspelled.
4.2.3 Standard Form List Options
You are able to define parameter or options that offer different qualities: e.g. Image quality with a form list that offers the options good/moderate/bad.
These options will show up in the CMR Report page.
Sequences like T1 mapping sequence or First Pass Perfusion can be defined.
These sequences will be added to the list in the Edit Exam page and will be added quickly to a report header to make it more descriptive.
Note: An indication driven workflow was introduced in cvi42|Report version 5.6. For implementations using this workflow, the configuration of sequences is managed in cvi42|Report.
4.2.5 Study Descriptions
Newly defined study descriptions will be displayed in a drop down list in Edit → Exam and will be part of your report header. Study descriptions will also be entered automatically when report data is transferred from cvi42|Report.
4.2.6 Referring Physician
You can create a list of referring physicians. Each referring physician can have multiple addresses to which a report might be returned.
They will be displayed in a checklist in Edit → Exam and if selected, will show up in the report header. Addresses will not be printed in report headers, they are there as a convenience for addressing returned reports.
Referring Physician names will also be entered automatically when transferred from cvi42|Report.
4.2.7 Patient History
This allows to define canned text, that will be displayed in list format for selection in Edit → Exam.
4.2.8 Normal ranges
18.104.22.168 Export / Import Normal Ranges

- Physician: Findings/Summary Text can be available to all physicians in cvi/span>42|Report, or just one in particular (for example a specialist with different reporting requirements).
- Findings/Summary Text: the text to appear on the report, adding in Normal Values to make the text dynamics and relevant to the current report data.
- Availability checkboxes: these control which report module the text should be associated with – Findings, Summary or both.
4.2.10 Structured Findings
Structured Findings is a report section and can be used as an alternative to Findings.
Add Structured Findings Text
Add new text. Optionally you can insert a normal value. Save Changes.
Add a new category.
To facilitate inter-center collaboration, administrators can import and export all findings texts (including their normal range dependencies) or selected categories of findings.
4.2.11 Z-Index Rulesets
188.8.131.52 Editing Z-Index Rule Sets
Rulesets correspond to a particular paper used for z-scoring, and so must be set up to use the same BSA Calculation and the same z-scoring / normal-value regression function used by the paper's authors.
- Define any limitations that apply to the rule (optional). For instance, the authors may state the upper or lower limits for age, BSA, etc. in their sample population, outside of which the paper should not be considered applicable.
- Select a the BSA Formula used in the paper. It does not matter what formula you use in cvi42|Report or cvi/span>42|Report for your analysis, the BSA as calculated by the formula stated here will always be used as the input to the z-score formula to ensure consistency.
- Select the z-score and normal-value regression function used in the paper.
- Enter a citation.
- Save the entry.
184.108.40.206 Creating Z-Index Rules
Rules correspond to regression curve parameters found within a source paper and will represent a single measurement (length, volume, mass, etc.).
- Name the specific parameter being reported/calculated.
- Gender: Select whether the parameter is gender specific.
- Enter the parameters that define the linear regression curve (α, β, γ).
- Measurement Type: specify if the parameter is a volume, length or area measurement.
Source: length and area are derived from custom measurements.
The source for volumetric measurements can be selected from a drop down list.
- Unit: The unit will be entered based on the selection, but allows for customization.
- Selection: z score rulsets allows for the input to the regression function (i.e. "x") to be calculated from multiple measurements; the Selection option specifies whether "x" will be calculated as the minimum, maximum, average or median of the multiple measurements.
Save the entry by clicking the checkmark.
