Non-ECG-gated unenhanced MRA of the carotids: optimization and clinical feasibility.

Objectives: To optimise and assess the clinical feasibility of a carotid non-ECG-gated unenhanced MRA sequence.

Methods: Sixteen healthy volunteers and 11 patients presenting with internal carotid artery (ICA) disease underwent large field-of-view balanced steady-state free precession (bSSFP) unenhanced MRA at 3T. Sampling schemes acquiring the k-space centre either early (kCE) or late (kCL) in the acquisition window were evaluated.

Reliability and diagnostic accuracy of qualitative evaluation of diffusion-weighted MRI combined with conventional MRI in differentiating between complete and partial anterior cruciate ligament tears.

Objectives: To assess the reliability and diagnostic accuracy of qualitative evaluation of apparent diffusion coefficient (ADC) mapping with magnetic resonance imaging (MRI) in differentiating between complete and partial anterior cruciate ligament (ACL) tears.

Methods: This prospective study protocol was approved by the institutional ethics review board and informed consent was obtained from all the patients. Eighty-five patients (35 women and 50 men, mean age 34.

Feasibility of dynamic MRI for evaluating velopharyngeal insufficiency in children.

Objective: To demonstrate the feasibility of dynamic MRI with near-real-time temporal resolution for analysing velopharyngeal closure.

Methods: Eleven children and young adults (seven girls, four boys, mean age: 8.4 years) with suspected velopharyngeal insufficiency (VPI), and one healthy volunteer underwent MRI (1.
