Summary: In this study, chest CT was found to be valuable in diagnosing COVID-19 pneumonia, especially for patients with negative initial RT-PCR results. Most COVID-19 lesions were located in multiple lobes in both lungs, with ground-glass opacity and consolidation being the main CT features. Patients with negative initial RT-PCR results were less likely to show pulmonary consolidation on CT.

Summary: This study developed a deconvolution method to reconstruct COVID-19 infection incidences from daily PCR tests and applied it to epidemic data sets in Beijing and Wuxi. By estimating the delay function, the method successfully detected associated infection events and identified incidence increases, providing new insights for prevention and control strategies.

Summary: This study evaluated the clinical value of chest CT scans compared to RT-PCR in diagnosing COVID-19, finding that chest CT has high sensitivity and high negative predictive value, making it a potential alternative primary screening tool for COVID-19 in epidemic areas. Even with a negative RT-PCR result, a positive CT finding may still suggest a COVID-19 infection.

Summary: Macau faced tremendous pressure during the COVID-19 pandemic due to its status as a gambling and tourism city with high population density. The government implemented decisive public health interventions, leading to successful control of outbreaks. The re-positive cases may be attributed to residual virus nucleic acid, suggesting the importance of post-discharge quarantine and repeat testing to minimize potential risks.

Summary: The prevalence and outcomes of re-activation of COVID-19 in discharged patients remain poorly understood. A study on 126 confirmed cases found that a small number of recovered patients may still carry the virus even after meeting discharge criteria.

Summary: The study validated a direct RT-PCR test on pooled saliva samples as an effective method of SARS-CoV-2 surveillance, with high accuracy and sensitivity. Preliminary results indicate that detecting viral RNA in saliva can serve as an efficient means for COVID-19 monitoring, especially in asymptomatic individuals.

Summary: This article reflects on global public health responses during the past three years, especially in the context of the COVID-19 pandemic. It highlights the prioritization of rapid and widespread testing in the US and discusses the limitations of the rapid antigen test and RT-PCR. It also explores the potential of RT-LAMP testing as an accurate and quicker alternative, while examining the reasons for the hesitancy in adopting it.

Summary: The purpose of this study was to review clinical data and formulate recommendations for using saline as a rinse to reduce re-positive COVID-19 cases. The results showed that nasal douche treatment can shorten the time for virus nucleic acid to turn negative, thereby reducing the occurrence of re-positive cases.

Summary: This study explores placental pathology in mothers infected with COVID-19 and finds that congenital transmission of SARS-CoV-2 appears to be rare. The protective properties of the placental barrier against viral infections from mother to newborn remain unclear, but the abundance of ACE-2 on the placental surface may contribute to adverse outcomes during pregnancy.

Summary: This study evaluated and compared the performance of three commercially available COVID-19 RT-PCR kits, with the Aridia (R) COVID-19 Real-Time PCR Test showing the best performance among them. However, the Novel Coronavirus (2019-nCoV) Nucleic Acid Detection Kit performed the worst among the three kits.

Summary: This study aimed to compare chest CT findings with RT-PCR test results in children with probable or definitive diagnosis of COVID-19. The study found that pulmonary lesions and consolidation were significantly higher in RT-PCR negative group, while lobe involvement percentages up to 25% were in favor of RT-PCR positive patients. Central and perihilar involvement were also more common in the RT-PCR negative group.

Summary: This study aimed to characterize thyroid nodules seen on Spectral Detector computed tomography (SDCT) and compare them with their Thyroid Imaging Reporting and Data System (TI-RADS) category on Ultrasound (US). The results showed that the spectral results of SDCT can assist in differentiating thyroid nodules of different risk levels.

Summary: The purpose of this study was to investigate the associations between cardiac magnetic resonance feature-tracking-derived myocardial strain parameters and volumetric function and hemodynamic parameters in patients with pulmonary hypertension. The results showed that impairment of myocardial strains was more strongly associated with alterations in ventricular function parameters than elevated pulmonary arterial pressure, limiting the diagnostic information of myocardial strain parameters in pulmonary hypertension.

Summary: The purpose of this study was to investigate the imaging characteristics and prognostic factors for the long-term survival of Behcet's disease (BD) with arterial involvement. The results showed that arterial lesions associated with BD usually involve multiple arteries and manifest differently in different types of arteries. Cardiac involvement and pulmonary artery aneurysm/dilation were independent prognostic factors for the survival of BD patients with arterial involvement.

Summary: The ability of pretreatment PET parameters and peripheral blood biomarkers to predict PFS and OS in NSCLC patients treated with ICIT was assessed. The study found that MTV and the number of SOI were independent risk factors for progression and overall survival, and the combination of these factors improved risk stratification.

Summary: This study investigated the potential of tin prefiltration and virtual monoenergetic imaging (VMI) in suppressing metal artifacts in high-resolution CT images of the lower extremities. The results showed that VMI reconstructions had better artifact reduction compared to T3D. VMI110keV had the least image noise. In terms of image quality, interpretability of bone-metal interface, and overall image quality, VMI110keV performed the best.

Summary: This study aimed to develop CT radiomics models to preoperatively identify lymph node (LN) status in resectable esophageal squamous cell carcinoma (ESCC) patients. The results showed that the combined model, integrating ESCC and LN radiomics features with clinical features, had the highest predictive ability among the three models. The combined model's predictive ability was validated in both the test and external validation cohorts.
