Summary: Intravascular ultrasound and near-infrared spectroscopy can identify vulnerable coronary atherosclerotic plaques. The association between statins and nonculprit lesion arterial wall lipidic content and subsequent nonculprit major adverse cardiac events was evaluated in this study. Patients were divided into two groups based on statin therapy and statin-naive status and underwent intravascular ultrasound and near-infrared spectroscopy analysis. Statin initiation at discharge provided the most benefit for events related to nonculprit lesions.

Summary: This study compared the effectiveness of FFR and IVUS PCI optimization strategies for long coronary lesions. The results showed that the FFR optimization strategy resulted in poorer functional PCI outcomes and larger myocardial ischemia burden compared to the IVUS optimization strategy. However, this difference did not have a statistically significant impact on clinical outcomes.

Summary: Coronary angiography has been the standard for diagnosing coronary artery disease and guiding percutaneous coronary intervention (PCI). Intravascular imaging (IVI) technologies are used in conjunction with angiography to better assess plaque morphology and optimize PCI. IVI has utility in preintervention assessment, procedural guidance, and postintervention evaluation. IVI's role in reducing major adverse cardiac events in complex lesions is emerging, and further studies are underway. This paper provides an overview of available IVI technologies, reviews evidence supporting their use in PCI, and advocates for broader utilization.

Summary: This study aimed to evaluate the clinical efficacy of intravascular ultrasound (IVUS)-guided percutaneous coronary intervention (PCI) in calcified coronary lesions. The results showed that IVUS-guided PCI in moderate/severe calcification lesions had good clinical outcomes comparable to non/mild calcification lesions after more than a year of follow-up.

Summary: This study evaluated the parameters measured by IVUS for the prediction of intermediate coronary lesions function and found that plaque burden and lesion length were independent risk factors. The model combining these two parameters showed better predictive ability for coronary artery function.

Summary: This study analyzed the serum markers and CTA characteristics of calcified nodules (CN) and found that CN is associated with higher serum ALP levels and plaque burden. CN has different CTA imaging features and can be used to predict its presence.

Summary: Coronary artery calcium (CAC) is a direct measure of an individual's coronary atherosclerotic burden. Higher levels of CAC are strongly associated with an increased risk of cardiovascular disease (CVD) events and individuals with very high CAC levels have a CVD risk similar to stable persons with a prior CVD event. Conversely, the absence of CAC (CAC=0) is associated with a low long-term risk of CVD, even among groups classified as high risk based on traditional risk factors.

Summary: This study investigated the feasibility and limitations of using deep learning-based coronary calcium scoring in PET-CT compared to ECG-gated non-contrast-enhanced CaCT. Results showed that PET-CT with AI-assisted CACS measurements had comparable results to CACS in coronary calcium CT. However, there were concerns about the relatively high false-negative results and tendency to underestimate.

Summary: The study compared the effectiveness and outcomes of optical coherence tomography (OCT)-guided rotational atherectomy (RA) with intravascular ultrasound (IVUS)-guided RA in treating calcified coronary lesions. Results showed that OCT-guided RA led to better stent expansion and potentially improved prognosis compared to IVUS-guided RA.

Summary: This study investigated the prognostic value of coronary CT angiography (CCTA) in heart failure patients with preserved ejection fraction (HFpEF). The results showed a higher prevalence of coronary atherosclerosis in the HFpEF group compared to the non-HFpEF group. During the follow-up period, participants with HFpEF exhibited a higher risk of major adverse cardiovascular events (MACEs) in different CAD-RADS categories. CAD-RADS = 1-2 increased the risk of nonfatal myocardial infarction, while CAD-RADS ≥ 3 were associated with cardiovascular mortality and hospitalization due to heart failure.

Summary: Comparing IVUS and CCTA, it is found that CCTA can accurately evaluate the local endothelial shear stress (ESS) similar to IVUS, which is useful for identifying relevant local flow patterns of plaque development, progression, and destabilization.

Summary: This study aimed to evaluate the diagnostic performance of a radiomics model for classifying hepatic lesions in colorectal cancer patients from portal-phase CT images. The radiomics model showed slightly lower overall discrimination index compared to radiologists, but performed well in differentiating liver lesions, particularly distinguishing metastatic lesions.

Summary: This study aimed to evaluate the role of routine ultrasound combined with computed tomography in identifying exclusion criteria in potential living kidney donors. A retrospective cohort study was conducted, and the results revealed that routine ultrasound had limited contribution to the eligibility decisions for renal donors.

Summary: The purpose of this study was to investigate the agreement between hemodynamic stresses derived from coronary computed tomography angiography (CCTA) and intravascular ultrasound (IVUS)/intravascular coronary angiography (ICA). The results showed that CCTA can serve as a satisfactory alternative to IVUS/ICA in morphology simulation and hemodynamic stress calculation, especially in the calculation of wall shear stress (WSS).
