6. Identify yourself
SL NO SEQUENCE IDENTIFICATION
1 T1 CSF BLACK
2 T1-CONTRAST CSF BLACK, VESSEL WHITE
3 T2 CSF WHITE
4 STIR CSF WHITE, ABDOMINAL FAT AND BACK FAT BLACK
5 DWI GHOST LOOK, CSF BLACK
6 ADC GHOST LOOK, CSF WHITE
7. T1W
1. Morphology of bones and
soft tissue
2. Most pathological lesions
appear hypo intense
against normal fatty marrow
8. T1C
1. Gives details about
cellularity and necrosis
2. Dynamic post contrast
will assess vascularity
of bone metastasis
3. Response assessment
9. T2W
1. Adds information about
morphology of bones and soft
tissue.
2. Most pathological lesions appear
hyper intenseagainst
normal marrow
10. IR sequence
1. Fat suppressed T2W sequence
2. More clear
3. Differentiate from T2 by back FAT[arrow]
1. Bright on T2
2. Darker on IR
4. Most pathological lesions appear
more hyper intenseagainst
normal marrow
