Trauma Imaging

Feb

Overview

Trauma imaging aims for rapid comprehensive assessment of injuries. Whole body CT is commonly used in major trauma. Imaging findings directly influence surgical and critical care decisions.

Head and Spine

CT is the primary modality for acute head and cervical spine injury. Rapid detection of hemorrhage and fractures guides urgent management. MRI may be used for spinal cord and soft tissue evaluation.

Abdominal and Pelvic

CT identifies solid organ injury vascular injury and free fluid. Contrast enhanced protocols improve detection of active bleeding. Interventional radiology may provide non surgical treatment options.

Extremity Imaging

Radiography and CT evaluate fractures and joint dislocations. MRI assesses soft tissue and occult bone injuries when needed. Imaging guides orthopedic management and rehabilitation planning.

MRI Basics

Overview

Magnetic resonance imaging uses magnetic fields and radio waves to create images. The technique provides high contrast for soft tissues. It is widely used in clinical practice.

Clinical Applications

MRI is used for brain spine joint and soft tissue evaluation. It aids in diagnosis of tumors and inflammation. It guides treatment planning for many conditions.

Safety Considerations

MRI requires screening for metal implants and monitoring for heating. Patients must remove metal objects before scanning. Staff must follow safety protocols.

Future Directions

Advances include higher field strength and faster sequences. New sequences improve tissue characterization. Research continues on functional and molecular MRI.

Imaging for Chronic Pain

Overview

Imaging helps identify structural causes of chronic pain and guides interventions. Modalities include radiography CT MRI and ultrasound. Correlation with clinical assessment prevents over reliance on imaging findings.

Spine and Facet

MRI and CT assess disc degeneration facet arthropathy and nerve compression. Imaging guides interventional procedures such as injections and ablations. Functional imaging may add information about pain generators.

Musculoskeletal Sources

Ultrasound and MRI evaluate tendinopathy bursitis and occult injuries contributing to pain. Dynamic imaging can reveal impingement and instability. Targeted imaging supports procedural planning.

Interventional Guidance

Image guided injections and ablations improve accuracy and outcomes for pain procedures. Fluoroscopy ultrasound and CT are used depending on target and access. Multimodal care integrates imaging with rehabilitation and pharmacologic therapy.

Intraoperative Volumetric Imaging O Arm Intraop CT

Overview

Intraoperative CT and cone beam systems provide three dimensional imaging during surgery to confirm hardware placement and guide resections.

Technique

Sterile draping rapid acquisition and integration with navigation systems enable real time surgical decision making.

Clinical Uses

Spine instrumentation verification cranial tumor resection guidance and orthopedic fracture fixation.

Limitations and Safety

Logistics OR workflow impact and radiation exposure to staff require protocols and training.

DEXA Bone Densitometry

Feb

Overview

DEXA measures bone mineral density at the spine and hip to assess osteoporosis risk and monitor therapy.

Technique

Dual energy acquisition separates bone from soft tissue. Standardized positioning and calibration ensure reproducible results.

Clinical Uses

Diagnosis of osteoporosis fracture risk assessment and monitoring response to bone directed therapy.

Limitations and Safety

Limited to bone density assessment. Artifacts from hardware or degenerative change can affect accuracy.

C Arm Fluoroscopy Mobile C Arm

Overview

C arm systems provide real time fluoroscopy in operating rooms and procedure rooms for orthopedic vascular and pain procedures.

Technique

Image intensifier or flat panel detectors variable geometry and pulsed fluoroscopy optimize dose and image quality.

Clinical Uses

Fracture fixation spinal procedures vascular access and image guided pain interventions.

Limitations and Safety

Radiation exposure to staff. Shielding and positioning reduce occupational dose.
