The CARE® Phantom system is a medical device system that is being developed has been designed to enable the quantitative measurement of the apparent diffusion coefficient (ADC) in the prostate of patients undergoing a multi-parametric MRI (mpMRI) scan to detect prostate cancer. The final device system will comprise three elements: a calibration mat containing phantoms and embedded monitoring software, a docking station to transfer data from the phantoms, and software as a medical device (SaMD) for calibrating the resulting mpMRI images.
In this clinical trial, patients will undergo MRI scanning in different scanners using the GSP Phantoms to provide mpMRI images and phantom data for subsequent in silico analysis. The captured images and data will be used to further develop and calibrate the GSP prototype SaMD part of the medical device system, and to establish the degree of optimised reproducibility that can be achieved.

| Determination of the Reproducibility of GSP CARE Reference Phantom on Different MRI Scanners | To determine the reproducibility of GSP CARE reference phantom corrected lesion ADC measurements when the phantom is used on different MRI scanners for measurement of ADC in prostate. Voxel-wise median ADC values will be obtained for each lesion region of interest (ROI), referred to in the synopsis as "ADC measurements". The study is designed for 3 pairwise comparisons of 3 MRI scanners, enabling reproducibility determination between each pair of scanners. The study is powered for each pairwise comparison, based on a single lesion per patient. | From date of first participant enrolment until the date of the final ADC measurement analysis, assessed up to 18 months. |
| Measure | Description | Time Frame |
|---|---|---|
| Assessment of Reproducibility Between MRI Scanners | To determine whether increasing the between scanner reproducibility enables sufficiently precise voxelwise median ADC measurements (i.e. variance is not inferior to a minimally acceptable variance) to be able to distinguish between the expected ADC values from clinically significant and clinically insignificant prostate lesions. | From date of first participant enrolment until the date of the final ADC measurement analysis, assessed up to 18 months. |

| Observation of the Extent to Which Biopsy Can be Avoided when Using GSP CARE Phantom System | To investigate the proportion of men who would receive a correct clinical recommendation that biopsy could be avoided using ADC measurements with and without GSP CARE reference phantom correction. This is a feasibility analysis to indicate data needed to power a trial to demonstrate a difference in proportion. Data will be presented graphically, with 95% confidence intervals using Wilson method. The study is not powered to show a statistical significance. Comparison of paired proportions within patient of recommendations using ADC measurements with and without GSP CARE reference phantom correction. | From date of first participant enrolment until the date biopsy results of participants are received, assessed up to 6 months. |
| Determination of Per-Lesion Diagnostic Accuracy of GSP CARE-Corrected ADC Measurements | To determine per-lesion diagnostic accuracy of ADC measurements, corrected using the GSP CARE reference phantom, for significant cancer in men scheduled for standard of care biopsy with Likert/PIRADS 3 or above scored MRI lesions. Sensitivity and specificity will be calculated per lesion, with 95% confidence intervals using Wilson method. Statistical significance will be based on 95% confidence intervals. | From date of first participant enrolment until the date of the final ADC measurement analysis, assessed up to 18 months. |
| Determination of the Association Between GSP CARE Reference Phantom Corrected Lesion ADC Measurements and Tumour Gleason Grade | From date of first participant enrolment until the date of the final ADC measurement analysis, assessed up to 18 months. |
| Investigation of Device Usability | From date of first participant enrolment until the date all radiographers and participants have completed a Usability Questionnaire, assessed up to 6 months. |
