Optimized Volumetry in Radiology: Interest in Pediatric Brain MRI in the Exploration of Focal Epilepsy
Multicentre cross-sectional study with prospective recruitment comparing the detection rate of lesions on brain MRI without and with quantitative volumetry and T1 relaxometry information during the management of children with suspected focal epilepsy.
Conservative Management of HSIL in Patients With Future Pregnancy Aspiration
Conservative management of high-grade squamous intraepithelial lesions (HSILs) seems safe and justified in young women (<30 years), but evidence is insufficient on whether it is also advisable for older women. This study will be conducted to analyze spontaneous HSIL regression rates in women of reproductive age and establish whether conservative …
Laser Speckle Contrast Imaging, Surgical Eye & ICG Fluorescence Imaging for Perfusion Assessment of the Gastric Conduit
Rationale Globally, esophageal cancer is the seventh most common cancer type, with over half a million cases reported in 2020. The survival of gastroesophageal cancer is poor and the prognosis is primarily determined by the possibilities for curative treatment. After resection of part of the esophagus and cardia, the reconstruction …
Pancreatic Fibrosis as a Prognostic Factor
In chronic pancreatitis, pancreatic fibrosis impairs the ducts patency and secretion and contributes to chronic pain. Another complication of long CP presence is pancreatic exocrine insufficiency (PEI) that is present in 30-90% of patients with CP. Currently, there are no reliable techniques for non-invasive assessment of the pancreatic fibrosis degree. …
Association Between the Composition of the Intestinal Microbiota and Tumor Response in Locally Advanced Rectal Cancer
This is an observational, single-centre study (RIPH3) for patients with rectal cancer soon to be treated with chemotherapy (+/- neo-adjuvant radio-chemotherapy) looking at the relationship between the composition of the gut microbiota before treatment and the tumour response after chemotherapy +/- radio-chemotherapy
Contrast-Enhanced Mammography for the Evaluation of Mammographic Microcalcifications
This clinical trial evaluates the added role of contrast-enhanced mammography (CEM), as well as imaging and blood biomarkers, for predicting the presence or absence of high-grade ductal carcinoma in situ (DCIS) or invasive cancer on pathology. Screening mammography is the mainstay of population-wide early breast cancer detection, and mammography-detected cancers …
Comparative Imaging Assessment of Valvular Heart Disease
The purpose of the study is to compare the various 2D and 3D methods of valvular heart disease quantification (Doppler, PISA, VCA, volumetric method) and strain with cardiac magnetic resonance (CMR) measurements of left and right ventricular systolic function strain and myocardial fibrosis assessment.
Collecting and Storing Tissue From Young Patients With Cancer
This laboratory study is collecting and storing tissue, blood, and bone marrow samples from young patients with cancer. Collecting and storing samples of tissue, blood, and bone marrow from patients with cancer to study in the laboratory may help doctors learn more about changes that may occur in DNA and …
Ultrahigh-frequency Ultrasonography (UHFUS) in Detection of Small Pulmonary Ground Glass Opacity (GGO)
The purpose of this study is to assess the feasibility of UHFUS on detection of GGOs in excised lung tissue and investigate UHFUS features of GGO in vitro. Each GGO was detected by palpation, UHFUS and open biopsy in sequence. The comparison of detection rate and time consumption were analyzed …
Fluid Responsiveness Evaluation by a Non-invasive Method in Children, Extended to PREterm Infants - FRENCH-PREMA
In this study, the investigators aim to validate a non-invasive marker of fluid-responsiveness in preterm infants (term below 37 gestational week) with acute circulatory failure based on standardized abdominal compression. This would allow physicians to identify which patient could benefit from a fluid expansion, thus avoiding a potentially useless or …
