High resolution MR imaging of hand is mandatory both to improve early diagnosis and for our understanding of diseases like Rheumatoid Arthritis and Osteoarthritis of wrist and finger joints. While 7 T promises excellent SNR for high resolution imaging of the hand, the usual approach of transmit or transceive arrays may not be the best solutions here, since arrays with a very high density and filling factor are required. This is due to the fact that the hand is a relatively small object and sample noise domination is not necessarily achieved. We present a combination of a volume transmit coil and a 12 channel high density receive (Rx) array for wrist imaging at 7 T.
