Rapid dynamic liver MRI with compressed-sensing sensitivity encoding (Compressed SENSE) can reduce respiratory motion artifacts. However, Since the central k-space filling is random or posterior half of the acquisition in Compressed SENSE, optimal acquisition timing is missed only using a conventional scan delay method for hepatic arterial dominant phase (HAP). We assessed a combination of Compressed SENSE with contrast enhanced robust angiography (CENTRA) for dynamic liver MRI. CS-CENTRA sequence achieved significantly higher arterial enhancement with comparable CNR compared to CS-conventional one in HAP. CS-CENTRA contributed to optimal acquisition timing for HAP.
