Cardiac MRI Features and Prognostic Value in Immune Checkpoint Inhibitor-induced Myocarditis.

Background Cardiac MRI features are not well-defined in immune checkpoint inhibitor (ICI)-induced myocarditis (ICI-M), a severe complication of ICI therapy in patients with cancer. Purpose To analyze the cardiac MRI features of ICI-M and to explore their prognostic value in major adverse cardiovascular events (MACE). Materials and Methods In this retrospective study from May 2017 to January 2020, cardiac MRI findings (including late gadolinium enhancement [LGE], T1 and T2 mapping, and extracellular volume fraction [ECV] scores) of patients with ICI-M were compared with those of patients with cancer scheduled to receive ICI therapy (pre-ICI group) and patients with viral myocarditis.

Prognostic impact of splenic vessel involvement and tumor size in distal pancreatectomy for adenocarcinoma: a retrospective multicentric cohort study.

Purpose: Splenic vessel involvement occurs frequently in pancreatic ductal adenocarcinoma (PDAC) of the body and the tail (B/T) but the impact on survival is unknown. We assessed the influence of radiological and pathologic involvement of splenic artery (p-SA +) and vein (p-SV +) on patient outcomes after distal pancreatectomy (DP) for PDAC.

Methods: From 2013 to 2019, all DP for PDAC in five centers were included.

Atelectasis prevention during anaesthesia using high-flow nasal cannula therapy: A paediatric randomised trial using MRI images.

Background: Atelectasis frequently occurs early on during anaesthesia in children. We hypothesised that positive expiratory pressure (PEP) generated via high-flow nasal cannula (HFNC) could prevent atelectasis in non-intubated children under general anaesthesia. The objective was to compare the volume of atelectasis present in patients treated via HFNC to that of patients treated via a face bag-mask without PEP.

Predictive ability of preoperative CT scan for the intraoperative difficulty and postoperative outcomes of laparoscopic liver resection.

Background: The surgical difficulty and postoperative outcomes of laparoscopic liver resection (LLR) are related to the size of the cut liver surface. This study assessed whether the estimated parenchymal transection surface area could predict intraoperative difficulty and postoperative outcomes.

Methods: LLRs performed between 2008 and 2018, for whom a preoperative CT scan was available for 3D review, were included in the study.

Prostatic artery embolization using three-dimensional cone-beam computed tomography.

Purpose: The purpose of this study was to report the use of three-dimensional (3D) cone-beam computed tomography (CBCT) for prostatic artery embolization (PAE) in patients with benign prostatic hypertrophy (BPH).

Materials And Methods: Twenty-three consecutive men who underwent PAE using 3D CBCT from June 2016 to September 2018, were retrospectively included in this observational single-center study. There were 23 men with a mean age of 73±12 (SD) years (range: 52-94years) with moderate to severe lower urinary tract symptoms (mean international prostate symptom score, 21±5.

Cardiac magnetic resonance assessment of left ventricular dilatation in chronic severe left-sided regurgitations: comparison with standard echocardiography.

Purpose: The purpose of this study was to investigate the potential additional value of cardiac magnetic resonance (CMR) in the assessment of left ventricular (LV) dilatation and dysfunction by comparison to standard echocardiography in patients with chronic left-sided valvular regurgitation.

Materials And Methods: We prospectively enrolled patients with chronic severe mitral regurgitation (MR) or aortic regurgitation (AR). They underwent standard echocardiography and CMR using aortic flow and LV-function sequences.

Tips & tricks for transoral approach for submandibular lithiasis (TASL).

Introduction: Sialolithiases mainly affect the submandibular gland. More often, the lithiasis is large and located at the junction of the middle and the posterior third of the duct, in the hilum region. In such situation, transoral approach is recommended to avoid sialadenectomy because of its lower morbidity.

Acute Coronary Syndrome With Immune Checkpoint Inhibitors: A Proof-of-Concept Case and Pharmacovigilance Analysis of a Life-Threatening Adverse Event.

Isolated cases of acute coronary syndrome (ACS) associated with immune checkpoint inhibitors (ICIs) have been described without the establishment of a formal cause-and-effect relationship between treatment and adverse event. We reported a case of ACS after the first administration of an ICI and with a fatal recurrence in another coronary area immediately after readministration. According to guidelines, causality was considered to be certain.

Prevalence and Risk Factors for Thrombotic Complications Following Venovenous Extracorporeal Membrane Oxygenation: A CT Scan Study.

Objectives: The aims of this study were to: 1) analyze the cannula-associated deep vein thrombosis frequency after venovenous extracorporeal membrane oxygenation using a CT scan and 2) identify the associated risk factors for cannula-associated deep vein thrombosis.

Design: Retrospective observational analysis at a single center.

Setting: Tertiary referral university teaching hospital.

Abdominal wall morphometric variability based on computed tomography: Influence of age, gender, and body mass index.

Introduction: Ventral hernia surgery does not usually account for the individuality of the abdominal wall anatomy. This could be both because medical imaging is rarely performed before surgery and because data on abdominal wall variability are limited. The objective of the present study was to perform an exhaustive morphometric analysis of abdominal wall components based on computed tomography (CT) scans.

Improved Assessment of Middle Ear Recurrent Cholesteatomas Using a Fusion of Conventional CT and Non-EPI-DWI MRI.

Background And Purpose: Recurrent middle ear cholesteatomas are commonly preoperatively assessed using MR imaging (non-EPI-DWI) and CT. Both modalities are used with the aim of distinguishing scar tissue from cholesteatoma and determining the extent of bone erosions. Inflammation and scar tissue associated with the lesions might hamper a proper delineation of the corresponding extensions on CT images.

Combined Management of a Bronchial Artery Fistula After Lung Transplantation.

A 46-year-old female patient exhibited massive endobronchial bleeding after dilation of a left bronchial anastomotic stenosis after lung transplantation, consistent with a bronchopulmonary artery fistula (BPAF). The BPAF was treated with a bronchial covered self-expandable metallic stent and percutaneous transcatheter pulmonary artery stent placement. BPAF is rare and leads to death in most cases because of massive hemoptysis.

A new CT dynamic maneuver "Mouth Opened with Tongue Extended" can improve the clinical TNM staging of oral cavity and oropharynx squamous cell carcinomas.

Objectives: Cross sectional imaging is mandatory for oral cavity and oropharynx head and neck squamous cell carcinoma's (ooSCC) local extension and TNM staging. However a complex anatomy and frequent dental metallic artifacts make it difficult. This study assesses the clinical benefit of "Mouth Open with Tongue Extended" dynamic maneuver at CT (CTmote) as compared to the conventional CT (CTconv) and MRI.

Value of early repeated abdominal CT in selective non-operative management for blunt bowel and mesenteric injury.

Objectives: To evaluate the performance of an early repeated computed tomography (rCT) in initially non-operated patients with blunt bowel and mesenteric injuries (BBMI).

Methods: This was a monocentric retrospective observational study from 2009 to 2017 of patients with a BBMI on initial CT (iCT). Patients initially non-operated on were scheduled for a rCT within 48 h.

Chest CT scan and alveolar procollagen III to predict lung fibroproliferation in acute respiratory distress syndrome.

Background: Lung fibroproliferation in ARDS patients is associated with mortality. Alveolar procollagen III (NT-PCP-III) is a validated biomarker of lung fibroproliferation. A chest CT scan could be useful for the diagnosis of lung fibroproliferation.

Malignant Aspergillus flavus Otitis Externa with Jugular Thrombosis.
