Multiparametric magnetic resonance imaging (mpMRI) of the prostate now plays a central role in the management of prostate cancer. Its use in the local staging of prostate cancer is well established [1,2],and mpMRI can also provide information about tumor aggressiveness [3-5], allows lesion localization for targeted biopsy [6,7] and can be used as part of an active surveillance program [8]. Additionally, there is developing evidence that mpMRI can play a role in the initial workup of patients presenting with suspicion of prostate cancer based on...

Approval was obtained from the institutional ethical review board, and the study was compliant with the Health Insurance Portability and Accountability Act. Written informed consent was obtained from all participating patients. Patients 20 men presenting to our prostate cancer MRI clinic as part of a diagnostic workup were prospectively consented to be scanned using an external phased array wearable pelvic coil (WPC) in addition to the standard diagnostic sequences obtained using a endorectal coil (ERC) and standard pelvic phased array coil (PPA) at 3T. All...

Qualitative T2w image analysis The results of the qualitative T2w image analysis are given in Table 3. Artifact severity was greater in T2w images acquired with the endorectal coil when compared with the wearable pelvic coil (ERC 2.01 ± 0.42 vs. WPC 1.39 ± 0.70, p=0.003). Motion artifact in the phase encode direction emanating from the interface of the endorectal coil and rectal wall was seen on 17 of 18 ERC T2w sequences (Figure 1). There was no statistically significant difference in overall image quality,...

Wearable pelvic coil imaging provides comparable image quality to an endorectal coil, potentially reducing the need for an endorectal coil. Wearable pelvic coil imaging showed reduced T2w artefact severity and inferior DWI zonal anatomy distinction when compared with an endorectal coil. Imaging with a wearable pelvic coil produces a lower signal to noise ratio than an endorectal coil.
