Steensma BR, et al. - In this prospective study involving 4 healthy volunteers and one prostate cancer [one of the most common forms of cancer in men] patient, researchers examined the signal-to-noise ratio (SNR) gain in prostate imaging at 7T as compared with 3T. SNR is expected to improve at 7T compared to 3T for prostate imaging. Using optimal coil setups for both field strengths, all subjects were scanned at 3T and at 7T. Investigators observed an increase in SNR for prostate MRI at 7T in comparison to 3T, which ranges from 1.7-fold to 2.8-fold. It is not possible to observe a direct relationship between BMI and SNR except that the subject with the highest BMI shows the lowest SNR at both field strengths and the lowest SNR gain at 7T. This is potentially associated with the reduced penetration depth of the RF fields at 7T. The authors concluded that compared to 3T, SNR improves prostate imaging at 7T.
