Ch 1 Clinical Anatomy

includes patholigical anatomy (study of anatomical changes caused by disease) & radiographic anatomy (study of body structures by different forms of radation)

different imaging techniques used for diagnosis

X Rays is the traditional method of diagnosis; however, X Rays that are directed to the body may penetrate and create a dark image if they pass through soft tissues, while those that are absorbed by dense tissues, such as bones, leave a white image.

a technique in which a fluoroscope (fluorescent screen) is used to view an X Ray image as organs are moving

• CT Scan (computed tomography)
• DSR (dynamic spatial resolution)
• Xenon CT (Xenon computed tomography

CT Scan - a rotating tube & recorder over around the person as X-rays are taken

DSR - ultra fast CT scanner are used to assemble a series of CT pictures & create a 3D image, can also be used to view in detail an organ in motion

Xenon CT - a CT taken in combination with inhaled Xenon (inert gas)

revealing all organs at their best angles with almost no blocking structures

beating heart, blood flow

indentifyling an area of a stroke (indicated area where blood flow is lacking)

• 1. an image is taken before and after the patient is given a contrast medium
• 2. used to see if there is a blockage

• 1. where radioactive isotopes are dectected. As the isotope decays it emits a gamma ray that is decteded making greater concentration in areas that are more active or are receiving more blood.
• 2. to follow the flow of blood to the brain and heart

• 1. high frequency (ultrasonic) sound ways that are sent through the tissues & can reflect (echo) off the body. echo is processed by the computer to produce an image
• 2. to detect developing fetuses
• 3. soft tissue & contrasting mediums can also used to create better images

MRI gives all the details and is the strongest out of all the types of techniques.
