H MRI is emerging as a viable modality for
lung parenchyma imaging. However,
1
H
lung-MR methods have inherently low signal-to-noise
ratio (SNR) in the parenchyma due to the lower
1
H
density (<0.2g/cc) and short T

.
Thus there are obvious gains to be made through
anatomically customized radio-frequency (RF) receiver
coil designs. In this work we propose a receiver RF coil
array topology designed for high SNR imaging of the
lung-cardiac anatomy at 1.5T and illustrate the
1
H
SNR improvement over a conventional 8 channel
ladder-like topology used routinely for cardio-thoracic
MRI.
