uses nuc med to decide if there is mets into the lymph nodes
dye is injected into cancer site then gama reads dye
what is the smpte pattern
pattern used to check quality of computer monitors
society of motion picture tv; engineers
what is the warnging range for opitcal density on the processor QC strip?
or - .10 to .15
what is the purpose of spot compression
to displace overlying tissue and improve compression, to better look at a lesion
FDA says qc strips must be held for days, phantoms for days and darkroom fog and filmscreen tests for days
30, 90, 360
if lesion appears no significant shift from MLO to ML
the lesion is central aspect of breast
core biopsy uses needle to sample
8 or 14 gauge, specimens usually containing calcs
what is the purpose of the XCCL?
to visualize deep lesions in the outer aspect of the breast that were not seen in the CC
what is the purpose of the phantom imaging?
to assure mammo system is taking adequate imaging
films must be stored for patients for at least years
10 if mammos are consistantly done there, otherwise 5 years
it the lesion is lower on the ML than the MLO then
the lesion is in the lateral breast
