Imaging of Extremities Flashcards
<p>This type of imaging makes high density tissues (like bones) appear white. Breaks in bones appear darker because the break is now void of dense material. If an arthrogram hi density liquid is injected into joint space, it makes the outline of softer tissue visible. </p>

What type of pathologies can an MRI show?
Brain and spinal cord
Tumors and cysts
Visceral organs
Uterus
<p>Rank an X-Ray, MRI, and CT based on price. </p>
<p>X-ray -- cheapest
CT -- affordable (more than X-ray)
MRI -- expensive </p>
<p>What type of bone pathologies can X-rays show us? </p>
<p>Osteoporosis
Tumors/Cancers
Arthritis </p>
<p>What type of chest pathologies can X-rays show us? </p>
<p>Enlarged heart
Lung conditions
Swallowed foreign object </p>
<p>This type of imaging is a mixture of computer and X-ray technology. It makes visual cross-sections of the body and shows organs, small boney structures, and trauma (especially to brain, spinal cord, and chest). Like X-ray, dye can be injected in tissues and make certain rogans and joints show up better. </p>
<p>CT </p>
<p>What type of bone pathologies can CTs show us? </p>
<p>Tumors/Cancers
Infection
Clots (think hematomas) </p>
<p>What type of things can a CT show us in the internal systems? </p>
<p>Detects injury and bleeds </p>
<p>What pathology is pictured? Describe what is happening</p>
<p>The sail is an anterior displacement of the radial fat pad. In adults it is commonly caused by radial head fracture and in children it is caused by supracondylar fractures.</p>
<p>What is the pathology that is occurring here?</p>
<p>Torn ACL</p>
<p>What bone is fractured here?</p>
<p>What section of bone is fractured?</p>
<p>What is the main concern for this fracture?</p>
<p>Femur fracture in the diaphysis: sub trochanter</p>
<p></p>
<p>Concerning because of the high vascularization of teh bone as will as the femoral triangle situation</p>
