Quantib Prostate
- Intraprostatic lesions
- MRI
Quantib Prostate provides the user with processing, visualization, and editing of prostate MRI images. The software can be used for semi-automatic segmentation of anatomical structures and provides volume computations, together with tools for manual editing. PI-RADS scoring is possible using a structured workflow.
Images shown for illustrative purposes only.
Quantib Prostate allows the radiologist to achieve slightly higher inter-reader agreement with mpMRI (vs bpMRI)2
For less experienced readers, using Quantib Prostate improved the inter-reader agreement and the diagnostic accuracy3
Increase sensitivity and positive predictive value in PCa diagnosis4

Quantib Prostate creates DICOM output that contains the following reports.
- A secondary capture series of the T2 image with the prostate and ROI contours
- A secondary capture series of the T2 image with the prostatic sub-regions and ROI contours
- A secondary capture series of a 3D rendering of the ROI and prostate segmentations
- A DICOM segmentation series of the prostate segmentation
- A DICOM segmentation series of the ROI segmentations
- Optionally, a DICOM RTStruct series of the prostate and ROI contours. Consult with a service and installation engineer to configure the RTStruct format matching your clinical workflow.
- Optionally, secondary capture series of an image-on-image overlay, which can be the biparametric combination image.
- A report is created, which can be exported as PDF format embedded in a DICOM file and/or as a DICOM secondary capture series. The report contains:
- Patient and study information
- Prostate segmentation results of- Prostate volume
- PSA
- PSA density
- General findings
- Comments as written in the text box
- A lesion summary, with the PI-RADS score, maximal axial dimension, and PI-RADS sector per lesion, and the location of each lesion indicated on the sector map. Additionally, four views of a 3D rendering of the lesions in the prostate are shown. Note that lesions are sorted on highest to lowest PI-RADS score, followed by decreasing axial dimension, and that the order therefore does not necessarily match the order in the user interface.
- A detailed section per lesion, specifying:
- Slice numbers matching the Quantib Prostate user interaction interface oContour on screenshot of T2 (in axial and sagittal view), ADC, and high b-value scan oVolume
- Maximal axial dimension oADC value (average and standard deviation) oPI-RADS sector
- PI-RADS score (per sequence and overall)
- Lesion findings as entered in the front-end
- Kinetic curves if a DCE scan is available
