the society for assisted reproductive technology (sart) method of embryo grading is unique, simple, and widely practiced, and its use has been mandatory for sart membership programs since 2010. developed by sart in 2006, the current embryo grading system categories, “good, fair, and poor,” are limited because they do not describe the best 1-2 embryos in the interest of keeping pace with the shi...

Introduction and Purpose The muscle injury grading systems are based in part on ultrasound (US) and magnetic resonance imaging (MRI). However, the prognosis by MRI is not clear. There is evidence that part of the return-to-play is conditioned by the severity of the injury [1], and in our experience, this severity is associated with muscle gap (quantifiable retraction between fibers). Recently, ...

Introduction Quality control (QC) protocols are now routinely used on clinical Magnetic Resonance Imaging (MRI) devices. Most of the time, these QC procedures are manufacturer-specific, and then not useable for multicenter projects involving multiple MRI systems from different vendors on different sites. The aim of the work package 1 of the Grand Ouest Glioblastoma Project (GOGP) [1], a multice...

Objective. (1)H MR spectroscopy (MRS) is widely performed for assessment of brain tumours and is considered a highly sensitive technique capable of differentiating benign from malignant conditions and tumour grading. Method. We present a case of a 69 year old woman who was suspected to have gliomatosis on MRI. Results. MRS performed using single voxel and chemical shift/multivoxel techniques wa...

BACKGROUND AND PURPOSE Magnetic resonance imaging (MRI) is important for detecting extracapsular pseudotumors, but there is little information on the accuracy of MRI and appropriate intervals for repeated imaging. We evaluated the sensitivity and specificity of MRI for detecting pseudotumors in 155 patients (167 hips) with metal-on-metal (MoM) hip arthroplasties that failed due to adverse react...

BACKGROUND The goal of this study was to determine the reliability of TCD in evaluation of vertebrobasilar arteries in comparison with brain MRA in patients suffering from acute vertebrobasilar stroke. METHODS Samples were patients with definite clinical diagnosis of vertebrobasilar stroke. For all patients brain MRI, MRA and TCD were performed during the first 48 hours of admission. Basilar ...

Background: Artificial intelligence (AI) models provide advanced applications to many scientific areas, including the prediction of pathologic grade tumors, utilizing radiology techniques. Gliomas are among malignant brain tumors in human adults, and their efficient diagnosis is high clinical significance. Objectives: Given contribution AI medical diagnoses, we investigated role deep learning d...
