BACKGROUND Although conventional MR imaging (MRI) is the most widely used non-invasive technique for brain tumor grading, its accuracy has been reported to be relatively low. Advanced MR techniques, such as perfusion-weighted imaging (PWI), diffusion-weighted imaging (DWI), and magnetic resonance spectroscopy (MRS), could predict neoplastic histology, but their added value over conventional MRI...

Dynamic contrast-enhanced MRI (DCE-MRI) is increasingly used to quantify and map the spatial distribution of blood-brain barrier (BBB) leakage in neurodegenerative disease, including cerebral small vessel disease dementia. However, subtle nature resulting signal changes make quantification challenging. While simplified one-dimensional simulations have probed impact noise, scanner drift, model a...

Objective: A comparison of the difference between two types field MR scan in diagnosis shoulder joint injury. Method: Randomly selected 153 patients with arthroscopic or open arthroplasty who had pain dysfunction treated our hospital from 2014 to 2017 were divided into 1.5 T group and 3.0 according strength MRI examination. Postoperative pathology was a gold standard. The sensitivity, specifici...

objectives our objectives were to determine if: 1) imaging pattern at recurrence is associated with delayed diagnosis, and 2) appearance at recurrence can be predicted based on appearance at presentation. conclusion imaging appearance at baseline does not reliably predict imaging appearance at recurrence. therefore, a high index of suspicion for the infiltrative pattern is required in assessmen...
