Optimization of DE-CTPA Images and Diagnostic Pathway: Using Low Concentration Iodine Contrast Material
The investigators aimed to compare the image quality and diagnostic performance of DECTPA using lower concentration iodine contrast materials and using normal concentration iodine contrast materials in the evaluation of suspected pulmonary embolism.
Predicting the Efficacy of Neoadjuvant Therapy in Patients With Locally Advanced Rectal Cancer Using an AI Platform Based on Multi-parametric MRI
Establish a deep learning model based on multi-parameter magnetic resonance imaging to predict the efficacy of neoadjuvant therapy for locally advanced rectal cancer.This study intends to combine DCE with conventional MRI images for DL, establish a multi-parameter MRI model for predicting the efficacy of CRT, and compare it with the …
Pulmonary Embolism WArsaw REgistry
Initiated in January 2008, The PE-aWARE (Pulmonary Embolism WArsaw REgistry) is an on-going single-centre prospective observational study of patients with confirmed acute pulmonary embolism (APE). Extensive data on consecutive patients with pulmonary embolism is collected and stored. The main objective is to collect and provide information on patients' characteristics, management, …
Etiology, Pathogenesis, and Natural History of Idiopathic CD4+ Lymphocytopenia
Background Idiopathic CD4+ lymphocytopenia (ICL) is a condition in which there is a decreased level of CD4+ lymphocytes (a type of white blood cell), which can lead to opportunistic infections or autoimmune disorders and diseases. Objectives To characterize the natural history with regard to CD4+ T cell count and onset …
Individual Cerebral Hemodynamic Oxygenation Relationships (ICHOR 1)
This is an observational study in patients who require clinical anesthesia. The main purpose of this study is to understand whether there are differences in the cerebral blood flow, and oxygen metabolism affected by different types of anesthesia. Subjects who require clinical anesthesia for a clinical MRI and for whom …
Prevalence and Trends of Antimicrobial Resistance of Helicobacter Pylori in Korea
To assess antimicrobial resistance rates and minimal inhibitory concentrations in H. pylori isolated from patients with upper gastrointestinal disease with long-term period.
Patient Experience Data in Radiation Oncology
The project is part of the overarching goal of improving patient-centric radiation oncology. This pilot project aims to develop an instrument that can be used to collect clinically relevant patient-reported outcome data on adverse effects during and after RT. This real-world evidence (RWE) database will be the basis to monitor …
BioMEL- Diagnostic and Prognostic Factors in Melanoma.
The investigators' hypothesis is that cutaneous melanoma, melanoma in situ, dysplastic nevi and benign nevi all differ in not only clinical characteristics but also molecular and genotypic characteristics. Patients with suspected primary cutaneous melanoma or a differential diagnosis, or secondary melanoma can be asked to participate in the first part …
Dijon Stroke Cohort
The Dijon Stroke Registry, accredited by the Registry Evaluation Committee, INSERM and Public Health France, has been studying the epidemiology of cerebrovascular accidents (cerebral infarction, intracerebral haemorrhages, meningeal haemorrhages) and transient ischaemic attacks (TIAs) within the city of Dijon since 1985. As a result of the development of therapies for …
