Figure 1From: Endogenous assessment of chronic myocardial infarction with T1ρ-mapping in patientsSpin lock pulse sequence used to obtain T 1ρ weighted images. The pulse sequence consists of 2 continuous RF pulses with opposite phase to compensate for B1 variations, and a refocusing pulse between the spin-locking halves to compensate for B0 errors, followed by the readout.Back to article page
