Nuclear medicine exam review

Static bone imaging is routinely performed how long after tracer administration to an adult: A)30min B)1hr C)2-3hr D)24hr C)2-3hr. Static bone imaging performed with a labeled diphosphonate compound is routinely performed 2-3hr after tracer administration. Which of the following structures normally appear as areas of increased activity on the bone images of adults: A) anterior iliac crests B) glenoid fossa C)sternoclavicular joints D)all of the above D)all the above. On bone images of adults, areas of normally increased tracer activity include all those listed as well as the sacroiliac, hip, and acromioclavicular joints and vertebral column. Which of the following conditions is visualized on a bone image as a photogenic area: A)attenuation B)tracer infiltration C)acute myocardial infarction D)osteomyelitis A) attenuation. A photogenic area is one in which a smaller number of photons is visualized-a cold spot. A material that absorbs photons may cause an attenuation artifact, an area of falsely decreased tracer concentration (jewelry, belt buckles, pacemaker)
