“…To date, however, there has been a lack of qualitative reproducibility that would make a prostate MRI finding more reliable for the referring physician [24]. The joint recommendations of the American College of Radiology (ACR), the European Society of Urogenital Radiology (ESUR) and the AdmeTech Foundation regarding performance of MP-MRI of the prostate as well as standardized findings (PI-RADS v2) are an important step towards an international standard which can strengthen the trust of the referring physicians in the method [12]. In the German-speaking realm, one step in this direction includes, among other things, current standardized implementation and protocol recommendations for prostate MRI [25].…”

/2 11/8 11 77 54 Fax: ++ 49/2 11/8 11 61 45 lars.schimmoeller@med.uni-duesseldorf.de ABSTR AC TPurpose To assess the current regional acceptance, valuation, and clinical role of multiparametric MRI (mp-MRI) in prostate cancer diagnostics by patients and physicians. Materials and MethodsOf 482 distributed standardized questionnaires, 328 patient and 31 physician questionnaires (urological and general practitioners in and around Düssel-dorf) were analyzed over a period of 11 months. Questions were asked concerning general knowledge about prostate cancer, current diagnostic procedures, and knowledge about mp-MRI and MRI-guided biopsy.Results 70 % of the patients regarded accurate and exact diagnostics of prostate carcinomas as very important and 68 % considered MP-MRI a useful technique. 28 % of the patients with elevated PSA levels and negative transrectal ultrasound-guided biopsy (TRUS-GB) received MP-MRI as a secondary diagnostic. More than half of the patients estimated their overall knowledge about prostate cancer mediocre or worse and wished for more information about MR diagnostics. The majority of physicians (55 %) ordered MP-MRI studies of the prostate and 68 % saw their basic role in secondary diagnostics.Conclusion In this regional assessment mp-MRI of the prostate was considered useful by patients and practitioners. Currently, there still is a considerable discrepancy between recommended and the actual number of conducted MP-MRI studies, particularly in patients after previous negative TRUS-GB, although practitioners already see the benefit in this patient collective. Even though the use of prostate MRI is frequently more established than suggested in the current German S3-guideline, its full potential has not yet been exploited. More comprehensive information about the applications and diagnostic benefits of prostate MRI is needed and desired among patients and physicians.

“…All scans were re-reviewed and evaluated by a single radiologist with prostate MRI experience, for 2 key purposes: (1) to ensure consistent results given that operatordependent heterogeneity may exist, and (2) to take into consideration the PI-RADs 2.0 scoring system that was established in November 2014 (11). Lesions from the first scan were identified as either index, or non-index lesions.…”

Introduction: The natural history of prostatic lesions identified on multiparametric magnetic resonance imaging (mpMRI) is largely unknown. We aimed to describe changes observed over time on serial MRI. Methods: All patients with ≥2 MRI studies between 2008 and 2015 at our institution were identified. MRI progression was defined as an increase in Prostate Imaging Reporting and Data System (PI-RADS; version 2) or size of existing lesions, or the appearance of a new lesion PIRADS ≥4. Patients on active surveillance (AS) were analyzed for correlation of MRI progression to biopsy reclassification. Results: A total of 83 patients (54 on AS and 29 for diagnostic purposes) underwent serial MRI, with a mean interval of 1.9 years between scans. At baseline, 115 lesions (66 index, 49 non-index) were identified. Index lesions were more likely than non-index lesions to increase in size ≥2 mm (36.2 vs. 7.3 %; p=0.002). Overall progression was more likely to be seen among the index cohort (34.8 vs. 7.6%; p<0.001). New lesions with PIRADS ≥4 were seen on second imaging in 13 (16.5%) men, and became the index lesion in 29 cases (34.9%). Eighteen men on AS showed evidence of MRI progression (five with new lesions, 13 with progression of a previous lesion). Biopsy reclassification was present in three men (16.7%) with and seven men without MRI progression (19.4%). Conclusions: Overall changes in size and PIRADS scores of index lesions on MRI were small. New lesions were common, but usually did not alter management.

“…To reduce these artifacts, patients should be required to empty the rectum and bladder prior to examination. If significant air in the rectum is detected in the planning sequences, decompression of the rectum via a rectal tube can be advantageous [12]. Enemas or laxatives should not be administered since these increase intestinal peristalsis and can intensify artifacts.…”

“…Nevertheless, T2w imaging is the most important sequence for detecting carcinomas in the transitional zone. The differentiation criterion here is primarily the architectural distortion followed by size [12]. Morphological T2w sequences are decisive for determining the location of focal lesions.…”

The Working Group Uroradiology and Urogenital Diagnosis of the German Roentgen Society has developed uniform recommendations for the preparation and implementation of prostate MRI. In the first part detailed recommendations are given in tabular form regarding 1. anamnestic data before prostate MRI, 2. termination of examinations and preparation of examinations, 3. examination protocol and 4. MRI-guided in-bore biopsy. In the second part, the recommendations are discussed in detail and relevant background information is provided. Key Points: Citation Format
