The CTC Registry allows facilities to collect data about CT colonography procedures, including patients’ demographic information, medical history and risk factors, procedure indications, and follow-up information.

A new case consists of up to two forms:

  • The Case Registration form captures patient information such as name, ID (e.g. SSN), date of birth, etc., as well as the exam date. A new case form is required for each exam, even if you have previously recorded a different CT exam for this patient.

  • The Exam form captures data from the patient’s colonography in two sections:

    • Section A is General information, such as the Interpreting Physician and various metrics about the exam (e.g. CTDIvol, scanner type), etc.

    • Section B, Post Examination and Adverse Results, covers exam results, including whether or not a polyp of at least 10mm was identified.

PDF versions of both forms are available for you to print and record data to assist your internal workflow. You can download forms individually, or download a single PDF "form package" containing all three forms.

Please do not mail the printable forms to the ACR.

CTC Data Submission Methods

There are three methods for submitting data to the CTC:

  1. Manual data entry (which is outlined in the Case Workflow section, below, and is described in detail in the articles for the CTC Case, Exam, and Polyp forms).

  2. Data for all three forms and multiple facilities can be submitted via a flat file upload to the registry. See CTC Data File Upload for details on creating and uploading a data file. 

  3. Web-based data transmission allows you to send data directly from your software vendor or IT department, saving time and reducing the risk of errors.

Case Workflow

To start a new case, select Register New Case from the Data Collection menu and follow the guidelines for the Case Registration form.

Once you have completed and successfully submitted the form, the screen displays a link labeled Go to the next stage: Exam form which opens an Exam form for the case. Refer to the Exam form article for details on completing the form.

If there were no polyps of at least 10mm found, then the case is completed once the Exam form is successfully submitted. If one or more polyps of at least 10mm were documented, then a link labeled Go to next stage: Polyp form appears which will start a Polyp form for the case. Refer to the Polyp form article for more information on the completing the form.

Do not use the Back button on your browser to navigate to a form; doing so will prevent your data from being stored in the registry. Always use the Data Collection menu to navigate to a form.

Updating a Case

You can update forms for a case by selecting the form from the Data Collection menu and selecting the appropriate case number from the table, or by using the search Filter. See Manual Data Entry for general guidelines on searching for, updating, and saving changes to a form.

Cancelling and Restoring a Form

All forms may be cancelled from within the form itself. If a form has been saved or submitted, a Cancel button is available at the bottom of the form. Click the button to cancel the form. Buttons - Save Submit Cancel

Note: The Cancel button is available only for a form that does not have a dependent form with a status of In Progress or Submitted; e.g. an Exam form will not have Cancel button if there is a Polyp form saved or submitted to the registry. In this scenario you must first cancel the Polyp form before cancelling the Exam form. To cancel a Case Registration form, you must first cancel any Exam and Polyp forms associated with the case.

After the form is cancelled the screen refreshes and a Restore button appears. Buttons - Save Submit Restore

To restore a cancelled form, click the Restore button at the bottom of the form. Make updates to the form, if needed, then click the Submit button to commit the form to the database.

Note: The dependencies for restoring forms are similar to those for cancelling forms – e.g. the Restore button is not visible in the Polyp form until the Exam form for the case has been restored and submitted to the registry.

Note: The Status column in search results tables shows the status of the Case Registration form, not the status of Exam form.
