Over the past years, the benefit of intravascular coils has been demonstrated providing a local SNR gain in comparison with external coils. Although matching and amplifying directly at the catheter tip could enhance signal quality, it could not be done due to space limitations. In this work we compared three coil concepts that bring matching and preamplifying to the catheter tip. Despite possible limitations due to space restrictions and artefacts from magnetic components, the results show that a significant SNR gain of up to 3 can be achieved with local matching and pre-amplification at the tip of the catheter.
