Projections Flashcards
[CR/IR] MLO
CR: enter medial aspect
IR: lat
DISADV: lacks unif. bc of of pectoralis inclusion
[CR/ADV] CC
CR: superior to inf
ADV: uniform br tissue
[BEST FOR] Spot Compression
true lesion superimposed
difficult to reach areas
used w/ magnif
[BEST FOR] Magnification
better for calcif
architectural distortion
mass margins
*compensate use of small focal spot
ECKLUND Technique [Displacement View/Image Displacement]
implant pushed post
br tissue pulled ant
modality to identify implant leakage
sonography
CC Proj. w/ FULL IMPLANT
manual technique w/ AEC turned off
exposue factor dep on size of br
CC ID
implant against chest wall
br tissue ant
FOR localization demo air fluid fat lvls @ lateral aspect of br
-used to locate lesion not seen on CC
Mediolateral [ML]
[CA @ 90 deg - enter medial exit lat]
FOR localization demo air fluid fat lvls @ medial aspect of br
Lateromedial [LM]
[CA @ 90deg -enter lat- exit med]
visualizes lesion in DEEP OUTER aspect of br not seen in standard CC [sag orientation of lat lesion @ AT]
Exagerrated CC [XCCL]
[CA @5-10 deg, elev IF maximally]
visualizes DEEP posteroMEDIAL tissue, demo medial lesion in true transverse/axial plane
CC FOR CLEAVAGE [CV]
Valley View
[CR: perp to centered cleavage]
triangulates lesions seen only in CC
defines lesion either as sup or inf aspect of br, separate lesions
CC w/ Roll [RC,MM]
[br rolled lat/med @ 10-15 deg, CA “ 10-15 deg]
confirms DERMAL br CALCI,
demo obscure comb over subcutaneous fat
Tangential [TAN]
demo PALPABLE LUMP in post tissue, isolate palpable lump for imaging
