Report Features

Get started by selecting one or more Corporate Account, at least one corresponding Facility, and a time frame of interest using the Exam From - To filter.

Exam Search Tab

The report enables you to query exam data using a variety of criteria:

  • Sort Table Filter: View performance results sorted either by date or by turnaround time. 

  • Modality, Physician NPI, CPT Code, Anatomy, and Study Name: Pinpoint areas to further explore in the Turnaround Summary report using available values.

  • Place of Service: Sort performance by Ambulatory, Inpatient and ED care settings.

  • Number of Readers: View the impact on turnaround times of having more than one reader, e.g., a resident and attending physician.

Place of Service and Number of Readers are new data elements that can help you refine performance results and determine areas to focus on for quality improvement.

  • Turnaround (filter): Limits the report results displayed based on the turnaround time range selected. 

The sample report below shows performance results for submitted exams from July 1 through July 31, 2020 for the study CT Head W/O Contrast and with the table sorted by turnaround times.

The Turnaround sliding filter is a useful way to identify exams with unusual values, such as very high turnaround times or negative times. The sample report below shows a report view with the table sorted by date. The far-right column displays the turnaround time, in hours, both numerically and with a bar to help highlight larger values. The bar is light blue for positive turnaround times and red for negative values.

Note: Negative turnaround times (in red) likely indicate incorrect data and should be investigated.


Hover over a value in the Turnaround Time column to see the details of the calculation, including the date the final report was signed.

Turnaround Time Summaries Tab

This report can help you quickly identify turnaround time performance anomalies or patterns by reviewing data across a variety of variables. The report can also provide insight into the effect of new processes and performance improvement efforts. For example, the report can help you assess the impact of new scheduling methods, changes in staffing levels, and new equipment. Performance trends can be delved into for a specific time period for one or more facilities, modalities, and exam types.

The tables display the number of exams and average turnaround time by Facility ID, NPI, Modality, Place of Service, and Number of Readers. 

Rows in each table are sorted by descending average turnaround time. The light gray bars highlight exam volumes and the blue bars indicate turnaround times. All summary tables are interactive; clicking on a row will filter the rest of the report, including the exam table. For example, click on ED in the Place of Service Summary table as shown in the example below to display data for the ED only in all other tables and charts.

To undo a selection, click on it again, or click the Undo button in the bottom left corner of the report.

The Sort Exam Table filter sorts the exams by turnaround time or by date.

Note: Each heat map calendar has a separate legend as the ranges may be different. Click a date in the Date Exam Completed calendar to filter the report.  Scroll through the Date Final Report Signed Calendar to view the corresponding dates when the final reports were signed or through the GRID Exam Search Table for more detail.
