Magnetic resonance imaging (MRI) allows accurate assessment of Crohn's disease (CD), but requires gadolinium injection. Diffusion-weighted (DW)-MRI yields comparable performances in small bowel CD. We compared the accuracy DW-MR enterocolonography (MREC) and magnetic index activity (MaRIA), performed an external validation Clermont score assessing inflammation CD.This was observational prospective study a single-center cohort. A total 130 CD patients underwent consecutively MREC with...
Whether diffusion-weighted imaging (DWI)-MRI is of value in detecting and assessing inflammation ileal Crohn's disease (CD) remains poorly investigated.To compare DWI-MR enterography (MRE) with conventional MRE estimating small bowel CD, to determine an apparent diffusion coefficient (ADC) threshold differentiate active from non-active lesions assess inter-observer agreement.Thirty-one CD patients the Clermont-Ferrand IBD unit involvement were consecutively prospectively included between...
Summary Background Endoscopic mucosal healing is the current therapeutic target in Crohn's disease. However, transmural could lead to better outcomes. Aims To assess whether or magnetic resonance imaging (MRI) are targets than endoscopic predict long‐term improved outcome disease Methods From our MRI database, we retrospectively identified all patients who had and colonoscopy within a 3‐month interval (median = 17.5 days). Four groups were considered: (no ulceration aphthoid erosion), signs...
Summary Background Magnetic resonance entero‐colonography enables accurate assessment of ileocolonic Crohn's disease, but the need for bowel cleansing and rectal enema limits considerably its use in daily practice. Aim We evaluated accuracy diffusion‐weighted magnetic with neither nor to assess endoscopic activity. Methods Forty‐four disease patients underwent prospectively consecutively [with apparent diffusion coefficient ( ADC ) Clermont score calculation] ileocolonoscopy Disease...
Pseudomyxoma peritonei (PMP) is a rare clinical condition characterized by mucinous ascites, typically related to appendiceal or ovarian tumours. Current standard treatment involves cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC), but recurrences occur in 20-30 per cent of patients. The aim this study was define the timing patterns recurrence provide basis for modifying follow-up these patients.This observational examined prospectively developed multicentre...
The prognostic value of the primary neoplasm responsible for pseudomyxoma peritonei (PMP) remains poorly studied. aim this study was to determine prognosis patients with extra-appendicular PMP (EA-PMP) treated optimally complete cytoreductive surgery (CCRS) and hyperthermic intraperitoneal chemotherapy (HIPEC).All CCRS HIPEC between 1994 2016 were selected retrospectively from a French multicentre database. Patients EA-PMP had pathologically confirmed non-neoplastic appendices matched in 1 :...
Magnetic resonance imaging [MRI] is a promising tool to evaluate therapeutic efficacy in ileocolonic Crohn's disease [CD].We aimed assess the feasibility of early MRI evaluation (week 12 [W12]) predict corticosteroid-free remission [CFREM] at W52 and prevent long-term bowel damage.All patients with active CD needing anti-tumour necrosis factor [anti-TNF] therapy were consecutively enrolled this multicentre prospective study. was performed before starting therapy, W12 W52. CFREM defined as...
AIMTo assess magnetic resonance imaging (MRI) and faecal calprotectin to detect endoscopic postoperative recurrence in patients with Crohn's disease (CD). CONCLUSIONFaecal MRI are two reliable tools POR CD.
Abstract Objectives Detection of liver metastases is crucial for guiding oncological management. Computed tomography through iterative reconstructions widely used in this indication but has certain limitations. Deep learning image (DLIR) use deep neural networks to achieve a significant noise reduction compared reconstructions. While reports have demonstrated improvements quality, their impact on detection remains unclear. Our main objective was determine whether DLIR affects the number...
