Introducing aPROMISE

aPROMISE (automated PROstate Specific Membrane Antigen Imaging SEgmentation) is a medical device software developed by EXINI Diagnostics AB. aPROMISE is a PACS platform that offers quantitative analysis and standardized reporting of PSMA PET/CT image assessments. The software has a solution for automated body segmentation and marking, quantifying and reporting of regions of interest (ROIs) considered as suspicious lesions 1,2. The automated segmentation of reference organs and detection of ROIs with high local intensity uptake, so called hotspots, provide enhanced consistency in quantitative analysis and intend to increase efficiency of PSMA PET/CT image assessments.

In prostate cancer, PET tracers targeting the Prostate-Specific Membrane Antigen (PSMA) have demonstrated high diagnostic accuracy for the detection of both regional and distant metastatic prostate cancer. The higher sensitivity and specificity of the PSMA PET in detecting metastatic prostate cancer, may have strong implications in management of patients.

The aPROMISE software automatically analyzes the CT image to segment anatomical regions, including the liver and the thoracic part of the aorta as reference organs. Subsequently, the PET image is analyzed to detect target hotspots, regions of locally elevated PSMA tracer intensities indicative of suspicious tumor tissue and metastasis. ROIs are marked by selecting from predefined hotspots or by manually drawing and are then labeled with type and location and quantified in terms of standard uptake values (SUVs) for tracer uptake intensities and their respective volumes. The standardized aPROMISE report provides consistent and quantitative assessments of PSMA PET/CT.

As of December 2020, aPROMISE is provided as a secure and compliant web application readily available from a web browser by logging in to apromise.psmaix.com. In Europe, the device is CE-marked according to the MDR 2017/745, and is available for clinical use in Sweden and Ireland.
