AB  - PURPOSE: The aim of this paper was to compare the open 1-T (O-1T) versus the 
      closed 1.5-T (C-1.5T) cardiac magnetic resonance (MR). PATIENTS/METHODS: The MR 
      examinations of two concurrent cohorts (each including 100 subjects) of patients 
      with suspected or known cardiac disease were reviewed. Such examinations were 
      obtained using O-1T or C-1.5T MRI. The bright-blood cine, T1-weighted (T1), 
      T2-weighed short-tau inversion recovery (T2-STIR), late gadolinium enhancement 
      (LGE) sequences were performed. Signal-to-noise ratio of blood (SNRb) or 
      myocardium (SNRm), and contrast-to-noise ratio of myocardium (CNRm) were 
      calculated. Subjective image quality (SIQ) of each sequence was graded as 
      0 = poor, 1 = intermediate, or 2 = optimal. Each examination was considered as 
      diagnostic when the report answered the clinical question. RESULTS: C-1.5T was 
      better than O-1T on cine for SNRb(median 172 versus 452), SNRm(71 versus 160) and 
      CNRm (107 versus 265) and on T2-STIR for SNRb(10 versus 29), SNRm(74 versus 261) 
      and CNRm(-67 versus -233)(P < 0.001). On LGE, SNRm was higher with O-1T than for 
      C-1.5T (312 versus 79, P < 0.001) while CNR was lower (158 versus 389; 
      P < 0.001). No significant differences were found for SNRb on LGE and both SNRm 
      and CNRm on T1 (P >/= 0.215). SIQ of O-1T was not significantly different from that 
      of C-1.5T for both R1 and R2 for cine, T1, and LGE (P >/= 0.157); for T2-STIR, SIQ 
      of O-1T was significantly lower (P = 0.003). R1-R2 concordance was almost perfect 
      (kappa = 0.816-0.894), and all examinations were diagnostic. CONCLUSION: Even though 
      quantitative measurements mostly favored C-1.5T, the SIQ of O-1T was not 
      significantly different for any sequence, with the only exception of T2-STIR.
