“…DCE-MRI significantly increases the accuracy of tumor detection and lesion evaluation and DCE-MRI increases the sensitivity for tumor detection particularly in the peripheral zone [29,30]. A high temporal resolution (at least 9 seconds) is a requirement for being able to measure the rapid enhancement of contrast agent in the prostate [31]. DCE-MRI is essential particularly for diagnosing recurrence after prostatectomy or radiotherapy [32].…”

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

Practical aspects of prostate MRI: hardware and software considerations, protocols, and patient preparation

The use of multiparametric MRI scans for the evaluation of men with prostate cancer has increased dramatically and is likely to continue expanding as new developments come to practice. However, it has not yet gained the same level of acceptance of other imaging tests. Partly, this is because of the use of suboptimal protocols, lack of standardization, and inadequate patient preparation. In this manuscript, we describe several practical aspects of prostate MRI that may facilitate the implementation of new prostate imaging programs or the expansion of existing ones.

“…One factor complicating the generation of high-level evidence for the use of MRI is the rapid advancement of MRI hardware and analysis techniques. MRI with ER coil was validated in the 1980's; more recently, centers have been using higher field strength magnets (3T) as well as multi parametric analysis including diffusion weighted imaging and dynamic contrast-enhanced imaging [9] . The utilization of different MRI imaging techniques may have contributed to the wide variability in reporting the sensitivity, specificity, and predictive values of MRI for staging purposes [10] .…”

Introduction: To examine the use of prostate magnetic resonance imaging (MRI) for staging after a new diagnosis of prostate cancer in our hospital system. There are no universally accepted recommendations to guide the use of MRI for staging purposes. In practice, prostate MRI is used to help distinguish T2 and T3 cancer. Prostate MRI is a modality that could aid in the triage of patients to radical prostatectomy or non-surgical treatments via accurate identification of organ-confined disease. Materials and Methods:We performed a retrospective review of prostate cancer patients who underwent staging MRI with 1.5T MRI with endorectal (ER) coil. We compared patient characteristics in patients who underwent surgery and those who did not, and used pathology reports from prostatectomy samples to calculate the negative predictive value (NPV) for extra-capsular extension (ECE) and seminal vesicle invasion (SVI). Results: We found that patients who underwent radical prostatectomy were younger, had lower Gleason scores, and had lower PSA values at diagnosis than patients who were not treated surgically. We calculated a NPV of 93.7% for SVI and 69.5% for ECE. We found variation in rates of accurate identification of T3 prostate cancer across the seven radiologists who interpreted MRI images in our study. Conclusions: 1.5T MRI with ER coil has a high NPV for SVI and a lower NPV for ECE. The utilization of 3TMRI may enable practitioners to more confidently rule out ECE. Future studies will be necessary to generate guidelines for use of MRI in prostate cancer staging.
