Document Summary

Lecture 2. 2 imaging of the musculoskeletal system fundamentals. X-rays have changed over time: we now have 3d reconstructions, shape, structure, density, how was the image taken, subject position with respect to x-ray source and film. Radiology in black and white: almost all pathology can be described simply by considering whether there is. Tissue thickness: thin -> doesn"t absorb many x-rays -> dark, thick -> absorbs many x-rays -> white. Cortical bone = white/outer bit of bone (blocking a lot of x-rays) Bone contains a lot of fat -> looks grey. Soft tissue = grey water density (muscle around shoulder) Fat in supraclavicular fossa is blacker than grey so it distinguishes b/w other tissues. Some flexibility eg. standing views, horiz beam. Great for soft tissue and bone marrow. Imaging in multiple planes (can be manipulated: availability variable, more expensive, limited functional info, contraindications pacemaker, cochlear implant, some aneurysm clips, long scan times (approx.
