An experiment is conducted to determine expected signal attenuation when the bore is empty (air-filled) or dielectrically loaded (patient-filled). Experimental results show that the MR bore shows impressive path loss performance at UHF, specifically 433 MHz, with greatest signal strength arriving at the receiver when the bore is dielectrically loaded.
