Multi-Contrast single breath-hold acquisition for cardiac MRI is highly desirable but is rate-limited by the need for a dedicated pre-scan per each acquisition. We revisit the notion of the necessary conditions for repeated preparation calibration steps, with the intent of loosening or selectively bypassing them in consecutive scan acquisitions. Under matched geometric conditions that account for sensitivities especially to off-resonance, we propose a simple bSSFP-SPGR based dual-acquisition method with a single intensive Cine calibration followed by a truncated SPGR calibration. This approach is demonstrated as Cine-Tag SSFP-SPGR CMR method that allows for one breath-hold functional acquisition of both scan sequences.
