Basic concept: using radioactive (element that remits radiation as it decays) substances coupled with biologically active chemicals to visualize structures (some organs love certain substances- like thyroid and iodine) Important physics concepts to know:Isotope = element on the periodic table with different # of neutrons but same atomic # Radioisotopes: technetium-99m, iodine-131 How nuclear medicine actually works: patient is made radioactive, they emit gamma rays, a gamma camera ha...

Chest X-Ray: Basics
Indications: broad (respiratory or cardiac disease, tube positioning, trauma) Characteristics of a good chest x-ray (PIER): Projection (AP, PA, lateral, lateral decubitus): heart will appear bigger on AP, but not by much, AP is better for intubated/sick patients, two views is KEYInspiration and ribs: do you see at least 8-9 posterior ribs (if too little inspiration, things can crowd and mimic abnormalities)Exposure: can you see the spine through the heart (too much penetra...

Imaging Modalities
If this episode doesn't fascinate you, I don't know what will!! RadiographsIonizing radiation hits a photosensitive film to produce an imageDigital radiography: photosensitive plate processed by electronic reader to be stored digitallyPACS system: picture archiving, communications, and storage systemPlain films = X-ray = radiograph = without contrast materialAdvantages: availability, less expensiveDisadvantages: limited detail, uses radiation (caution in pregnancy)Uses: chest x-ray, abdomen...
