  1. 1Why has MRI become important in musculoskeletal radiology?
    Due to advances in scanning speed, spatial resolution, computer 3D algorithms, and hardware, plus its superior soft tissue contrast
  2. 2What makes MRI particularly valuable for neuroradiology?
    MRI provides the best soft tissue contrast of all imaging modalities and can produce images in multiple planes (axial, coronal, sagittal, oblique) with equal ease
  3. 3Advantage of MRI's multiplanar imaging capability
    It can produce images in axial, coronal, sagittal and multiple oblique planes with equal ease, without needing to reposition the patient
  4. 4What body systems benefit most from MRI imaging?
    The brain, spine, and musculoskeletal system
  5. 5What recent improvements have helped claustrophobic MRI patients?
    Stronger magnetic fields (3 teslas), shorter exam times, wider and shorter magnet bores, and more open magnet designs
  6. 6Trade-off with open MRI magnet designs
    For magnets with equivalent field strengths, there is often a trade-off between image quality and open design
  7. 7What metallic implants contraindicate MRI?
    Pacemakers, cochlear implants, some medication pumps, certain cerebral aneurysm clips, metal fragments in eyes, and some metallic hardware
  8. 8Typical magnetic field strength of modern high-field MRI scanners
    3 teslas (compared to older scanners with lower field strengths)
  9. 9How does CT compare to MRI for musculoskeletal imaging?
    CT provides better bone detail and faster imaging but MRI offers superior soft tissue contrast for muscles, ligaments, tendons, and cartilage
  10. 10Main advantage of CT for bone imaging
    CT provides excellent spatial resolution and detail of bony structures, making it ideal for fractures and bone abnormalities
  11. 11Why is plain radiography still used as a first-line tool for musculoskeletal imaging?
    Due to broad availability, speed, relatively low cost, and effectiveness in diagnosing fractures, arthritis, bone tumors, and skeletal anomalies
  12. 12What musculoskeletal conditions are well-diagnosed with plain radiographs?
    Arthritis, bone tumors, fractures, and congenital skeletal anomalies
  13. 13DXA used for in musculoskeletal imaging
    Dual-energy X-ray absorptiometry (DXA) is used for evaluation of osteoporosis (bone mineral density)
  14. 14What imaging modality is best for evaluating bone age?
    Plain radiography (X-ray) of the hand, often analyzed with automated software like BoneXpert
  15. 15CT the test of choice for in neurological emergencies
    Cerebral hemorrhage and acute stroke evaluation due to rapid scan times
  16. 16How can nuclear medicine be useful in musculoskeletal imaging?
    Bone scans using tracers can detect infections, stress fractures, metastases, and areas of increased bone turnover before changes are visible on X-ray
  17. 17Role of ultrasound in musculoskeletal imaging
    Evaluating soft tissue masses, joint effusions, tendon injuries, and guiding interventional procedures like joint aspirations and biopsies
  18. 18Advantages of ultrasound for joint imaging
    Real-time dynamic imaging, no radiation, relatively inexpensive, and can guide procedures
  19. 19Angiography used for in neuroradiology
    Evaluating blood vessels in the brain and spinal cord, including cerebral aneurysms, vascular malformations, and stenosis
  20. 20What can CT angiography visualize with rapid IV contrast?
    Fine detail 3D images of carotid, cerebral, coronary or other arteries reconstructed from CT data
  21. 21How is functional MRI (fMRI) useful in neuroradiology?
    It can map brain activity and function, useful for pre-surgical planning and understanding neurological disorders
  22. 22Purpose of contrast agents in neuroimaging
    To enhance visualization of blood vessels, detect breakdown of blood-brain barrier, and identify abnormal tissues like tumors and inflammation
  23. 23What type of contrast is used in MRI?
    Gadolinium-based contrast agents that alter the magnetic properties of nearby water molecules
  24. 24Why is MRI better than CT for spinal cord imaging?
    MRI provides superior soft tissue contrast, allowing better visualization of the spinal cord, nerve roots, discs, and surrounding soft tissues
  25. 25What spinal conditions are best evaluated with MRI?
    Disc herniations, spinal cord compression, tumors, infections, demyelinating diseases, and ligamentous injuries
  26. 26Role of PET in neuro-oncology
    Distinguishing between tumor recurrence and radiation necrosis, staging, and monitoring treatment response using metabolic activity
  27. 27What areas of potential advancement exist in MRI?
    Functional imaging, cardiovascular MRI, and MRI-guided therapy
  28. 28Interventional neuroradiology
    Minimally invasive image-guided procedures for treating neurological conditions like aneurysms, strokes, and vascular malformations
  29. 29What procedures do interventional neuroradiologists perform?
    Aneurysm coiling, mechanical thrombectomy for stroke, embolization of vascular malformations, and vertebroplasty
  30. 30How is ultrasound used in musculoskeletal interventions?
    As a guide for biopsies, joint aspirations, injections, and drainage procedures to minimize damage to surrounding tissues
