To investigate and compare the values of 3.0 T MRI T1, T2 and T2* mapping quantification techniques in evaluating cartilage degeneration of the shoulder joint. This study included 123 shoulder joints of 119 patients, which were scanned in 3.

Performance of machine learning-based coronary computed tomography angiography for selecting revascularization candidates.

Background: Limited studies have investigated the accuracy of therapeutic decision-making using machine learning-based coronary computed tomography angiography (ML-CCTA) compared with CCTA.

Purpose: To investigate the performance of ML-CCTA for therapeutic decision compared with CCTA.

Material And Methods: The study population consisted of 322 consecutive patients with stable coronary artery disease.

Quantitative analysis based on chest CT classifies common and severe patients with coronavirus disease 2019 pneumonia in Wuhan, China.

Objective: This study aimed to compare quantifiable radiologic findings and their dynamic change throughout the clinical course of common and severe coronavirus disease 2019 (COVID-19), and to provide valuable evidence for radiologic classification of the two types of this disease.

Methods: 112 patients with laboratory-confirmed COVID-19 were retrospectively analyzed. Volumetric percentage of infection and density of the lung were measured by a computer-aided software.

Myocardial injury and risk factors for mortality in patients with COVID-19 pneumonia.

Background: Coronavirus disease 2019 (COVID-19) pneumonia tends to affect cardiovascular system and cause cardiovascular damage. This study aimed to explore the prevalence of myocardial injury and risk factors for mortality in patients with COVID-19 pneumonia.

Method: Two hundred and twenty-four consecutive patients with confirmed diagnosis of SARS-CoV-2 infection and definite outcomes (discharge or death) were retrospectively analyzed.

COVID-19 patients with hypertension have more severe disease: a multicenter retrospective observational study.

This study aims to explore the effect of hypertension on disease progression and prognosis in patients with coronavirus disease 2019 (COVID-19). A total of 310 patients diagnosed with COVID-19 were studied. A comparison was made between two groups of patients, those with hypertension and those without hypertension.
