Highly accelerated knee magnetic resonance imaging using deep neural network (DNN)-based reconstruction: prospective, multi-reader, multi-vendor study.

In this prospective, multi-reader, multi-vendor study, we evaluated the performance of a commercially available deep neural network (DNN)-based MR image reconstruction in enabling accelerated 2D fast spin-echo (FSE) knee imaging. Forty-five subjects were prospectively enrolled and randomly divided into three 3T MRIs. Conventional 2D FSE and accelerated 2D FSE sequences were acquired for each subject, and the accelerated FSE images were reconstructed and enhanced with DNN-based reconstruction software (FSE-DNN).

MRI Findings of Isolated Oculomotor Nerve Palsy after Mild Head Trauma in a Pediatric Patient: Case Report.

Introduction: Traumatic oculomotor nerve injury is usually caused by severe head trauma and is generally associated with other neurological deficits such as basilar skull fracture, orbital injury, or subarachnoid hemorrhage. Isolated traumatic oculomotor nerve injury after minor head trauma and its MRI findings are rarely reported.

Case Presentation: We report a case of a 13-year-old girl with mydriasis, limited inferior and medial movement of the left eyeball, and left ptosis after a mild bump of the left forehead and eye into an electricity pole.
