The aim of this study was to describe visualisation rate and appearance of all pericardial sinuses and recesses and to evaluate whether there is a significant difference between visualisation of these sinuses and recesses on 2-, 4-, 16- and 64-slice multidetector computed tomography (MDCT).
We retrospectively analysed 588 MDCT scans of the chest obtained with a protocol for pulmonary embolism.
The visualisation rate of any pericardial recess was 85.2%. The rates on 2-, 4-, 16- and 64-slice MDCT were 74.7%, 90.6%, 90.3% and 88.7%, respectively. There was a statistically significant difference in visualisation rates of pericardial recesses between 2-slice MDCT and other MDCT systems (p<0.01). Age, and 4-, 16- and 64-slice MDCT versus 2-slice MDCT and the presence of pleural effusion appeared as significant predictors of the presence of any recess.
Visualisation rates of pericardial recesses are higher with 4-, 16- and 64-slice MDCT than with 2-slice MDCT. Therefore, radiologists need to be familiar with the different appearances of pericardial recesses on MDCT to avoid misdiagnosis.
本研究旨在描述所有心包窦和隐窝的可视化率及其外观,并评估在 2 层、4 层、16 层和 64 层多层螺旋 CT(MDCT)上观察这些窦和隐窝是否存在显著差异。
我们回顾性分析了 588 例采用肺栓塞协议进行的胸部 MDCT 扫描。
任何心包隐窝的可视化率为 85.2%。2 层、4 层、16 层和 64 层 MDCT 的可视化率分别为 74.7%、90.6%、90.3%和 88.7%。2 层 MDCT 与其他 MDCT 系统之间心包隐窝的可视化率存在统计学差异(p<0.01)。年龄以及 4 层、16 层和 64 层 MDCT 与 2 层 MDCT 以及胸腔积液的存在是心包隐窝存在的显著预测因素。
与 2 层 MDCT 相比,4 层、16 层和 64 层 MDCT 心包隐窝的可视化率更高。因此,放射科医生需要熟悉 MDCT 上心包隐窝的不同表现,以避免误诊。
