Multiparametric cardiovascular magnetic resonance in patients with myocarditis with consecutive follow-up and a comparison between non-COVID-19 and COVID-19-associated myocarditis.

Background: The pattern of myocardial injury and dysfunction development during follow-up is unclear in patients with myocarditis. This study aims to explore the developmental pattern of myocardial injury and cardiac dysfunction during the follow-up of myocarditis by cardiac magnetic resonance (CMR) and differences in short-term follow-up CMR performance between patients with coronavirus disease 2019 (COVID-19)-associated myocarditis (CAM) and non-COVID-19-associated myocarditis (NCAM).

Methods: Data of patients with clinically diagnosed myocarditis who underwent follow-up CMR were retrospectively collected.

Impact of fat content on lumbar spine DWI performance: A sex-based comparative study.

The management of caesarian scar pregnancy with or without a combination of methods prior to hysteroscopy: Ovarian reserve trends and patient outcomes.

Study Objective: This study compared the efficacy and safety of a combination of uterine artery embolization or methotrexate before hysteroscopy in the treatment of cesarean scar pregnancy.

Methods: We divided 276 cesarean scar pregnancy patients into three groups. Group A underwent direct hysteroscopy; Group B received uterine artery embolization plus hysteroscopy; Group C received the systemic administration of methotrexate prior to hysteroscopy.

Development and validation of a radiomics-based nomogram for the preoperative prediction of microsatellite instability in colorectal cancer.

Background: Preoperative prediction of microsatellite instability (MSI) status in colorectal cancer (CRC) patients is of great significance for clinicians to perform further treatment strategies and prognostic evaluation. Our aims were to develop and validate a non-invasive, cost-effective reproducible and individualized clinic-radiomics nomogram method for preoperative MSI status prediction based on contrast-enhanced CT (CECT)images.

Methods: A total of 76 MSI CRC patients and 200 microsatellite stability (MSS) CRC patients with pathologically confirmed (194 in the training set and 82 in the validation set) were identified and enrolled in our retrospective study.

Prognostic value of regional strain by cardiovascular magnetic resonance feature tracking in hypertrophic cardiomyopathy.

Background: Few studies have demonstrated the performance of regional strain by cardiovascular magnetic resonance (CMR) feature tracking in hypertrophic cardiomyopathy (HCM) patients, and the prognostic value of segmental strain remains unknown. This study aimed to explore the prognostic implications of strain parameters generated by CMR feature tracking analysis in HCM patients.

Methods: In total, 104 clinically diagnosed HCM patients and 30 healthy volunteers were enrolled in this study, and all patients underwent a standard CMR examination.

MRI-based radiomics model for distinguishing endometrial carcinoma from benign mimics: A multicenter study.

Purpose: To develop and validate an MRI-based radiomics model for preoperatively distinguishing endometrial carcinoma (EC) with benign mimics in a multicenter setting.

Methods: Preoperative MRI scans of EC patients were retrospectively reviewed and divided into training set (158 patients from device 1 in center A), test set #1 (78 patients from device 2 in center A) and test set #2 (109 patients from device 3 in center B). Two radiologists performed manual delineation of tumor segmentation on the map of apparent diffusion coefficient (ADC), diffusion-weighted imaging (DWI) and T2-weighted imaging (T2WI).

Long-Term Observation and Treatment of Epithelioid Haemangioendothelioma of the Mediastinum: A Case Report.

Epithelioid haemangioendothelioma is a rare angiogenic tumour originating from vascular endothelial or pre-endothelial cells, and it can occur anywhere in the body, such as the liver, lung, bone, spleen, lymph nodes, parotid gland, and thyroid. In the fifth revision of the WHO classification, epithelioid haemangioendothelioma (EHE) was described as a malignant vascular neoplasm composed of epithelioid endothelial cells, distinct from epithelioid angiosarcoma. We, herein, report one patient with EHE of the left upper mediastinum who underwent resection and radiotherapy during the first therapeutic process.

In vivo evaluation of the levator ani muscle in primiparous women using diffusion tensor imaging and fiber tractography.

Objective: To characterize the levator ani muscle (LAM) injury after first vaginal delivery and investigate the clinical application of diffusion tensor imaging (DTI) and fiber tractography in evaluating the LAM.

Methods: Fifty-eight primiparous women at 6 weeks after vaginal delivery and 27 nulliparous women as controls underwent T2-weighted sequence and DTI sequence of the pelvic floor. A LAM scoring system was used to characterize the morphological changes.

Cardiogenic shock in an 8-year-old child secondary to anomalous coronary origin and course: a case report on the value of coronary computed tomography angiography and cardiac magnetic resonance.

Cardiogenic shock is a severe disease caused by primary failure of cardiac function. Myocardial infarction is the most common cause of cardiogenic shock. It is common in adults but rare in children.

Performance of cardiovascular magnetic resonance strain in patients with acute myocarditis.

Background: To explore the value of myocardial strain derived from cardiac magnetic resonance (CMR) feature tracking in evaluating left ventricular function in acute myocarditis and its relationship with the left ventricular ejection fraction (LVEF) and late gadolinium enhancement (LGE).

Methods: A total of 115 cases of clinically suspected acute myocarditis, confirmed by CMR, were collected from two centers and divided into groups with reduced and preserved ejection fraction (EF). Fifty normal volunteers were enrolled as the control group.

COVID-19 with acute cholecystitis: a case report.

Background: The 2019 novel coronavirus (COVID-19) presents a major threat to public health and has rapidly spread worldwide since the outbreak in Wuhan, Hubei Province, China in 2019. To date, there have been few reports of the varying degrees of illness caused by the COVID-19.

Cystic intraductal papillary neoplasms with infiltrating carcinoma of the intrahepatic bile duct: A case report.

Introduction: Intraductal papillary neoplasms of the bile duct (IPNB) is a kind of rare disorder with low incidence but high misdiagnosis due to untypical symptoms and non-specific laboratory indicators. Herein, we report a case of cystic type IPNB with infiltrating carcinoma of the intrahepatic bile duct presented as a single giant cystic mass of the liver.

Patient Concerns: A 51-year-old woman was admitted due to right upper abdominal discomfort for 10 months.

Influences of scan-position on clinical ultra-high-resolution CT scanning: a preliminary study.

The aim of this study is to access influences of scan-position on clinical ultra-high-resolution CT scanning. We proposed a breath-hold assisted ultra-high-resolution scanning technology (scan scheme G) and compared with scan scheme A (regular CT plain scan) and scheme B (1024 ultra-high-resolution scan with patients stay in supine position). A total of 30 patients with fGGO were included in this study.
