本研究的目的是评价64层多排螺旋CT(MDCT)和320层MDCT之间不同冠状动脉钙化评分方案的辐射剂量和噪声水平之间的关系。本研究中使用了心脏QRM体模(1个小号和1个中号)。针对小尺寸体模,提出了120 kVp和10 mAs的低剂量成像方案(0.336 mSv)在64-MDCT成像和小尺寸体模中(0.2 mSv)在320-MDCT病例中,在64层MDCT成像中,中等尺寸体模(2.73 mSv)为120 kVp,80 mAs;在320层MDCT成像中,中等尺寸体模(1.58 mSv)为120 kVp,80 mAs。我们的研究结果表明,人们可以在不牺牲诊断准确性的情况下,在临床上使用较低剂量的方案来早期诊断冠心病。
The purpose of this study was to evaluate the relationship between radiation dose and noise level on various coronary calcium scoring protocols between 64-multidetector computed tomography (MDCT) and 320-MDCT. The cardiac QRM phantoms (1 small size and 1 medium size) were used in this study. Lower-dose imaging protocols were proposed for optimization with the parameters of 120 kVp and 10 mAs for small-size phantom (0.336 mSv) in 64-MDCT imaging and small-size phantom (0.2 mSv) in 320-MDCT case, and 120 kVp and 80 mAs for medium-size phantom (2.73 mSv) in 64-MDCT imaging and medium-size phantom (1.58 mSv) in 320-MDCT case. Our results suggest that people can apply lower-dose protocols in the clinical use for early diagnosis of coronary disease without sacrificing diagnostic accuracy.
