2. IV. Medical tools A. Autopsy 1. Used to establish cause of death or to verify death. 2. Can be used to detect hidden disease, educate, or determine criminal activity

3. B. Medical imaging 1. Allows to physicians to peer inside to provide clues to help diagnose disease. 2. Several common ones: a. X-ray-( radiography) pass x- rays through body to produce 2D image b. Computed tomography-(CT) thin scan x-rays stacked to give 3D

5. c. Dynamic Spatial Reconstructions- (DSR) x-rays make 3D life sized images that can be moved to any angle d. Digital Subtracted Angiography- (DSA) X-rays and colored dyes allow to assess vessel blockages

7. e. Positron Emission Tomography- (PET) radioactive material injected and tracks metabolic changes f. Magnetic Resonance Imaging- (MRI) measures protons and they are magnetized by radio waves G. Ultrasound- high frequency sound passed through and produces images (sonar)
