A 32\u2010channel array consisting of eight shielded 3LD blocks (32LD\u2010SH) was constructed and validated for in\u2010vivo use. The SNR, parallel imaging, and transmit performance were compared to a previously published 16\u2010channel LD array (16LD). The effect of top loading was investigated by placing arms on top of the coils and measuring S\u2010parameter changes. In vivo imaging of multiple anatomies was performed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      In single block experiments, the RF shield impacted SNR and  performance by &lt;5%. The 3LD blocks had 80% higher peripheral SNR and 25% higher SNR at a depth of 10\u2009cm.
