83 Background: A biopsy-based RT-PCR assay (Oncotype DX Prostate Assay) providing a Genomic Prostate Score (GPS) as a measure of tumor aggressiveness and multi-parametric prostate MRI (mpMRI) are clinically utilized predictors of adverse pathology at prostatectomy. These tests have not been directly compared and it remains to be determined whether they provide independent information. Methods: We evaluated the association between GPS results (scale 0-100) and baseline endorectal mpMRI in men with clinically localized PCa. MR studies were reviewed to a five-tier scale of increasing suspicion of malignancy. Mean apparent diffusion coefficient (ADC) was calculated from a single dominant lesion. Mean rank of the GPS (0-100) and GPS-predicted likelihood of favorable pathology among MRI strata were compared with the Kruskal-Wallis test. Regression analysis was performed between mean ADC and scaled GPS within CAPRA risk groups. Results: Of 332 patients who received GPS testing at a single institution, 94 were identified with low (n=59) and intermediate (n=35) CAPRA risk prostate cancer who received mpMRI within a two-year interval of prostate biopsy. A broad distribution of GPS was observed across categories defined by mpMRI criteria. Among intermediate risk patients both GPS and the GPS-predicted likelihood of favorable pathology were associated with MR score (p=0.01 and p<0.01, respectively). For low risk patients, neither GPS nor likelihood of favorable pathology were significantly different across MR findings (p=0.12 and p=0.21, respectively). Mean ADC was not significantly associated with GPS or likelihood of favorable pathology for either low (p=0.24) or intermediate (p=0.91) risk categories. Conclusions: While a broad distribution of GPS was observed across mpMRI criteria, increasing GPS was associated with highly suspicious MRI findings in men with intermediate risk PCa. No significant associations were observed between MRI categories and either GPS or likelihood of adverse pathology in low risk patients.

Introduction: As we progress to an era when patient autonomy and shared decision-making are highly valued, there is a need to also have effective patient-centered communication tools. Radiology reports are designed for clinicians and can be very technical and difficult for patients to understand. It is important for patients to understand their magnetic resonance imaging (MRI) report in order to make an informed treatment decision with their physician. Therefore, we aimed to create a patient-centered prostate MRI report in order to give our patients a better understanding of their clinical condition. Methods: A prototype patient-centered radiology report (PACERR) was created by identifying items to include based on opinions sought from a group of patients undergoing prostate MRI and medical experts. Data was collected in semi-structured interviews using a salient belief question. A prototype PACERR was created in collaboration with human factors engineering and design, medical imaging, biomedical informatics, and cancer patient education groups. Results: Fifteen patients and eight experts from urology, radiation oncology, radiology, and nursing participated in this study. Patients were particularly interested to have a report with laymen terms, concise language, contextualization of values, definitions of medical terms, and next course of action. Everyone believed the report should include the risk of MRI findings actually being cancer in the subsequent biopsy. Conclusions: A prostate MRI PACERR has been developed to communicate the most important findings relevant to decision-making in prostate cancer using patient-oriented design principles. The ability of this tool to improve patient knowledge and communication will be explored.

Summary Aim: Minimally invasive resection of hyperfunctional parathyroid glands is an alternative to open surgery. However, it requires a precise preoperative localization. This study evaluated the diagnostic use of magnetic resonance (MR) imaging, parathyroid scintigraphy, and consecutive image fusion. Patients, methods: 17 patients (9 women, 8 men; age: 29-72 years; mean: 51.2 years) with primary hyperparathyroidism were included. Examination by MRI used unenhanced T1- and T2-weighted sequences as well as contrast-enhanced T1-weighted sequences. 99mTc-MIBI scintigraphy consisted of planar and SPECT (single photon emission tomography) imaging techniques. In order to improve the anatomical localization of a scintigraphic focus, SPECT-data were fused with the corresponding MR-data using a modified version of the Express 5.0 software (Advanced Visual Systems, Waltham, MA). Results of image fusion were then compared to histopathology. Results: In 14/17 patients, a single parathyroid adenoma was found. There were 3 cases with hyperplastic glands. MRI detected 10 (71%), scintigraphy 12 (86%) adenomas. Both modalities detected 1/3 patients with hyperplasia. Image fusion improved the anatomical assignment of the 13 scintigraphic foci in five patients and was helpful in the interpretation of inconclusive MR-findings in two patients. Conclusions: Both MRI and 99mTc-MIBI scintigraphy sensitively detect parathyroid adenomas but are less reliable in case of hyperplastic glands. In case of a scintigraphic focus, image fusion considerably improves its topographic assignment. Furthermore, it facilitates the evaluation of inconclusive MRI findings.
