Summary: CACS scan with Sn100 kVp prior to CCTA imaging on dual-source CT could reduce overall radiation dose. Compared with routine CCTA imaging, CACS scan shows advantages in reducing the number of scans, shortening the scan length, and decreasing the dose.

Summary: Among the three artery-based ordinal grading methods, the length-based method is identified as the most reliable for evaluating coronary artery calcium on non-electrocardiogram (ECG)-gated low-dose chest computed tomography (LDCT), showing highest inter-observer agreement and agreement with ECG-gated calcium scoring CT.

Summary: The study aimed to evaluate the impact of virtual monoenergetic imaging (VMI) and quantum iterative reconstruction (QIR) on the accuracy of coronary artery calcium scoring (CACS) using a virtual noniodine (VNI) reconstruction algorithm. The results showed that CACS(VNI) using VMI and QIR had strong correlation and excellent agreement with the reference scans. The CACS increased with decreasing keV levels, leading to an overestimation in some cases. The effects of different QIR levels were less consistent and seemed to depend on individual conditions.

Summary: The study aimed to use deep learning technology to assess CAC scoring in patients with high CAC, showing that the DL tool underestimates CAC load in patients with Agatston scores >= 1000, but is able to correctly assign Agatston scores >= 1000 with sufficient image quality.

Summary: The study evaluated the impact of ASIR-V on the accuracy of ultra-low-dose CAC scoring, finding that ASIR-V can reduce noise in CT scans but introduces substantial inaccuracies and significant underestimation compared to standard-dose CAC scoring, despite noise normalization. Additionally, a change in risk-class was observed in some patients.

Summary: Coronary artery calcium (CAC) is associated with the risk of incident sudden cardiac death (SCD), particularly among primary prevention patients with low-intermediate risk. Stratification of SCD risk through CAC measurement can identify patients who are most likely to benefit from further downstream testing in the early stages of coronary heart disease (CHD).

Summary: It remains unclear whether a coronary artery calcium (CAC) score alone is sufficient to determine the risk of obstructive and nonobstructive atherosclerotic plaque in symptomatic patients. This study found that the characterization of atherosclerotic disease burden by CAC score is imperfect, but subgroups of CAC scores showed pathogenic patterns of disease progression and stratified long-term prognostic risk.

Summary: This study compared the image quality and lung nodule detectability of deep learning image reconstruction (DLIR) and adaptive statistical iterative reconstruction-V (ASIR-V) in ultra-low-dose CT. The results showed that compared with ASIR-V, DLIR reduced image noise, increased nodule detection rate, and improved measurement accuracy on ultra-low-dose chest CT images.

Summary: The study found that low-dose unenhanced CT had low detectability of pancreatic cystic lesions and main pancreatic duct dilation. For small pancreatic cysts and slight main pancreatic duct dilatation, the use of low-dose CT as a screening tool is not recommended.
