PURPOSE: The purpose of this study was to investigate the development and evolution of the microwave ablation (MWA) lesion in the normal lung by using a swine model at various time points and to compare post-procedural computed tomography (CT) and gross pathologic findings during the first month post-ablation. MATERIALS AND METHODS: Twenty-seven percutaneous MWA procedures were performed on swine lungs at 100W for either 2min (low dose, 18 ablations) or 10min (high dose, 9 ablations)...

PURPOSE: To compare the diagnostic performance of T2-weighted Dixon, T1-weighted and Short-Tau Inversion Recovery (STIR) MR images for the detection of radiographically occult fractures (ROF) of the hip and pelvis in elderly patients after low-energy trauma. MATERIALS AND METHODS: A total of 22 patients older than 50 years with suspected ROF after low-energy trauma was prospectively included. There were 9 men and 13 women, with a mean age of 80.9 years±12.5 (SD) (range: 52-100 years)...

PURPOSE: To evaluate the safety and feasibility of peripheral percutaneous endovascular procedures in a large group of outpatients with peripheral arterial disease (PAD). MATERIALS AND METHODS: We retrospectively evaluated all consecutive patients who underwent peripheral transluminal angioplasty (PTA) for PAD of the lower extremities as "Out-Patient Admission Protocol" (OPAP) from January 2005 until December 2015. A total of 498 consecutive patients (305 men and 193 women) with mean age of 66±10 (SD) years (range: 37-90 years) were evaluated...

PURPOSE: To qualitatively and quantitatively compare unenhanced ultra-low-dose chest computed tomography (ULD-CT) acquired at 80kVp and 135kVp. MATERIALS AND METHODS: Fifty-one patients referred for unenhanced chest CT were prospectively included. There were 29 men and 22 women, with a mean age of 64.7±11.6 (SD) years (range: 35-91 years) and a mean body mass index of 26.2±6.3 (SD) (range: 17-54.9).

Hemarthroses and muscle bleeds are well-known and well-documented complications in pediatric and young adult hemophilia patients. In contrast, deep bleeds in atypical locations can be a diagnostic challenge, since clinicians and radiologists are often unfamiliar with their clinical and radiological features. Some atypical bleeds, however, can be life-threatening or severely disabling, highlighting the need for prompt, accurate diagnosis. Rare bleeds include central nervous system bleeds (including intracranial and spinal hematomas), urogenital bleeds, intra-abdominal bleeds (mesenteric and gastrointestinal wall hematomas) and pseudo tumors in unusual locations like the sinonasal cavities...

PURPOSE: This purpose of this systematic review was to determine the safety and efficacy of arterial embolization as the primary treatment for grade III-V liver trauma, excluding the postoperative use of arterial embolization. MATERIAL AND METHODS: A total of 24 studies published between January 2000 and June 2018 qualified for inclusion in this study. Four of them were prospective studies and 20 were retrospective. A total of 3855 patients (mean age, 33.5 years; range: 22-52...

Tumor heterogeneity in ovarian cancer has been reported at the histological and genetic levels and is associated with adverse clinical outcomes. Tumor evaluation using standard computed tomography or magnetic resonance imaging techniques does not account for the intra- or inter-tumoral heterogeneity in advanced ovarian cancer with peritoneal carcinomatosis. As such, computational approaches in assessing tumor heterogeneity have been proposed using radiomics and radiogenomics in order to analyze the whole tumor heterogeneity as opposed to single biopsy sampling...

PURPOSE: The purpose of this study was to report the feasibility of computed modelization and reconstitution of the paranasal sinuses, before and after trauma, from CT data. MATERIALS AND METHODS: We modeled and reconstructed the paranasal sinuses of two patients (A and B), before and after trauma, using two different softwares (3DSlicer® and Blender® ). Both patients had different numbers and locations of fractures. The 3DSlicer® software was used to create a 3D model from CT data...

PURPOSE: The purpose of this study was to compare non-invasive high-spatial-resolution postmortem cardiac magnetic resonance imaging (MRI) and autopsy findings for evaluating the septal insertion of atrioventricular valves in fetuses. MATERIALS AND METHODS: Five fetal heart specimens including two normal hearts, one heart with complete atrioventricular septal defect (AVSD) and two hearts with linear insertion of atrioventricular valves (LIAVV; gestational age 17 to 34 weeks) were studied with cardiac MRI using a 4...

PURPOSE: In France, a national evaluation is given annually to radiology residents. The aim of this study was to perform both a docimological analysis of the quality of the questionnaire and a statistical analysis of the results. MATERIALS AND METHODS: This retrospective study, which included French radiology residents from Year 1 to Year 5 of residency, was performed from 2015 to 2017 across 25 medical universities in France. Both qualitative and quantitative docimological analyses were performed as assessed by the Cronbach alpha coefficient, the difficulty of question (PDI), and the coefficient of discrimination (Rir)...

PURPOSE: To compare the outcomes in patients who had transjugular intrahepatic portosystemic shunts (TIPS) placed for hepatic hydrothorax with those who had it placed for refractory ascites. MATERIALS AND METHODS: One hundred and forty-seven patients who underwent TIPS placement for refractory fluid accumulation were included. There were 97 men and 50 women with a mean age of 56.1±9.7 (SD) years (range: 25-81 years). Of those, 32 patients (32/147; 21.8%) had refractory hepatic hydrothorax and 115 (115/147; 78...

PURPOSE: The purpose of this study was to evaluate the feasibility, safety, and efficacy of portal vein recanalization (PVR) and propose a new classification for better selecting candidates with portal vein occlusion (PVO) in whom PVR could be feasible. MATERIALS AND METHODS: The charts of 15 non-cirrhotic patients in whom stent placement using a trans-hepatic approach was attempted for the treatment of PVO with cavernous transformation were reviewed. There were 12 men and 5 women with a mean age of 47±12 years (range: 22-60 years)...

INTRODUCTION: The purpose of this study was to develop a convolutional neural network (CNN) to determine the extent of over-scanning in the Z-direction associated with lung computed tomography (CT) examinations. MATERIALS AND METHODS: The CT examinations of 250 patients were used to train the machine learning software and 100 were used to validate the results. Each lung CT examination was divided into cervical, lung, and abdominal areas by the CNN and 2 independent radiologists, and the length of each area was measured...

PURPOSE: The purpose of this study was to describe the positioning of bone tunnels of arthroscopic anatomical reconstruction of lateral ankle ligaments (AAR-LAL) and identify radiological measurements associated with short-term clinical outcome one year after surgery. MATERIALS AND METHODS: A total of 61 patients were included in this IRB-approved retrospective study. There were 52 men and 9 women, with a mean age of 36.3 ± 10.8 (SD) years. AAR-LAL was performed to treat chronic instability secondary to strain sequelae after failure of conservative treatment...
