Abstract:
Objective To evaluate the value of contrast-enhanced whole-heart coronary magnetic resonance angiography ( CE CMRA ) at 3.0 T in the delineation of cardiac venous anatomy. Methods Contrast-enhanced whole-heart CMRA at 3.0T was performed in 43 consecutive subjects using ECG-triggered, navigator-gated, inversion-recovery prepared, segmented gradient-echo sequence with a 32-channel cardiac coil. The visibility of the coronary veins was graded visually using a 4-point scale.Continuous variable was expressed as (-x)±s. The paired student t test was used to evaluate the differences of the coronary sinus (CS) ostium diameter in anteroposterior and superoinferior directions. Results CMRA examination was successfully completed in 40 subjects with acquisition time of ( 6. 9 ± 1.8 ) min. The cardiac veins were finally evaluated in 38 of 40 (95.0%) subjects. The mean distance of the posterior vein of the left ventricle (PVLV) and the left marginal vein (LMV) to the CS ostium were (3.34 ± 0. 90) and (6. 12 ± 1.02) cm, respectively. The mean visibility scores of CS, posterior interventricular vein (PIV),PVLV, LMV, and anterior interventricular vein (AIV) were 4.0 ± 0.0, 3.4 ± 0. 5, 3.4 ± 0. 5, 3.0 ± 0. 8,and 3. 3 ± 0. 5, respectively. The diameter of the CS ostium in the superoinferior direction ( 1.13 ±0. 26) cm was larger than that in the anteroposterior direction (0. 82 ± 0. 19) cm (t = -4. 31 ,P <0. 05).Conclusion Contrast-enhanced whole-heart CMRA at 3.0 T can clearly depict the cardiac venous anatomy.
