Greater accuracy,

Nerve blocks

Muscle spasticity / hypertrophy
botox

Biopsy
[todo]

Fluoroscopy
neck, spine, joints but radiation. Real-time imaging.

Ultrasound
used most widely due to low cost, accessibility, no radiation, reasonable accuracy. Ultrasound can't image bone so not good for spine. Real time imaging.

CT
high spatial resolution but radiation, and higher cost. Not real time but near real time (image, adjust needle, image again)

MRI
high spatial resolution, no radiation, but high cost. Not real time but near real time (image, adjust needle, image again)

Fusion
Multiple imaging modalities?
