Standard MRI Protocol Examples

This section provides detailed protocol examples for common magnetic resonance exams. Brain protocols include diffusion, fluid sensitive sequences, and post contrast imaging. Spine protocols include sagittal and axial sequences with field strength dependent parameter ranges. Musculoskeletal protocols include joint specific sequences and cartilage evaluation. Body protocols include liver, kidney, and pelvic imaging with typical sequence order and reconstruction settings. Each protocol includes rationale for parameter choices.

Protocol Optimization Techniques

This section explains methods for optimizing magnetic resonance protocols. Parallel imaging reduces scan time and improves patient comfort. Variable density sampling improves resolution and supports advanced reconstruction. Adjusting echo time, repetition time, and flip angle helps reduce artifacts and improve contrast. Small scale validation studies help departments test changes and evaluate image quality.

Adapting Protocols for Patients

This section provides guidance on modifying protocols for pediatric patients, claustrophobic patients, and patients with implants or limited mobility. Pediatric protocols require shorter scan times and careful coil selection. Claustrophobic patients may require open bore systems or comfort strategies. Patients with implants require careful review of conditional labeling and operating modes. Adjusted parameter ranges and positioning tips help maintain diagnostic quality while minimizing repeat imaging.
