A few patients experience side effects from the contrast material, including nausea and local pain. We acknowledge that there may be alternative approaches for artifact reduction [10]. Yet, it does not exert enough effect on bowel peristalsis in order to improve IQ in T2w. The finding that the metastasis-free survival for men with Grade 2 adenocarcinoma was only 58% at 10 years suggested that there was a role for a more active monitoring strategy in some men.125 More contemporary trials, including PIVOT and Protec T, support surveillance rather immediate treatment in contemporary patients, most likely to get diagnosed with serum PSA where the risk of overdiagnosis has been established.126,127. Furthermore, there is usually a means of communication with the staff such as a buzzer held by the patient which can be used for contact if the patient cannot tolerate the scan. Study type The discrepancy of the results in the literature on HBB and ME most likely explains why there was no consensus reached regarding this topic in current guidelines such as the Prostate Imaging and Reporting Data System (PI-RADS) v2.1 (10).
