CAS These MR coils can be placed on the surface of the body, e.g. There are two studies [7, 11] which are methodologically and technically similar to our study setup, demonstrating higher IQ and lower motion-related artifacts with HBB in T2w images. The increase in DWI IQ translated into significantly better perception of overall IQ of the whole mpMRI exam and logistic regression analysis revealed ME as the single significant predictor of good whole MRI IQ. 06/2018 These detector pads are also known as "coils", and they contain antennae to detect the MRI signal used to make detailed pictures of your prostate. decision will depend on the proximity of the metal implants to the area examined by the MRI.
