Volumetric Report

About Volumetric Reports

A volumetric report contains information about the volume of an object, the Macdonald Criteria and the Response Evaluation Criteria in solid tumors (RECIST). Macdonald Criteria is a 2D tumor criteria for gadolinium-enhancing T1-weighted lesions. The algorithm gives the longest diameter of the object within original slices multiplied by the longest perpendicular diameter within the same slice. RECIST is an evaluation criteria for gadolinium-enhancing T1-weighted lesions. The algorithm gives the longest diameter of the object within original slices.

Handling Volumetric Information

A volumetric report:

  • Is created for an object and stored with the object if you select Report.

  • Stays valid as long as the associated object is not modified.

  • Is stored with the patient data as long as the object is not modified.
  • Calculates object volume to two decimal places if it is less than 10 cm3. Anything greater is calculated to one decimal place.

The shape and position of an object must be verified in SmartBrush before creating a report. The report itself only gives information about volumetric measurements.

Values calculated from an outlined object depend on the resolution of the corresponding image set, including the object. Take this into account if you use the calculated values to make decisions about further treatment.

Reviewing and Exporting Reports

Existing reports can be reviewed using Viewer. Existing reports can be stored/exported using the Export function of Patient Data Manager.
