Tumour Infection Scanning Notes
Mark lesions / site of symptoms unless lesion is very small when markers may distort or obscure it.
WHAT IS MEANT BY LONG AXIS ?
We will protocol for long axis rather than Sagittal or Coronal in most cases, as we do not know where the lesion is in respect to the limb being examined.
If you find yourself placing the marker Anterior or Posterior, choose Sagittal as the long axis
If the marker is medial or lateral - choose Coronal
ALSO, as patients limbs are often rotated in the magnet, rotate the sagittal/Coronal appropriately
Shoulder
Elbow
Wrist Hand

Tumour Infection
Soft Tissue or Bone Mass
Axial T2FS and T1
Long Axis T1 FSPD
If bone lesion present add wide FOV T1 to look for skip lesions
Post Tumour Surgey Follow Up
Long axis STIR
Axial T2Fs Axial T1
If there is abnormal high signal on the axial T2FS ...
Axial T1FS then give Gad
Axial and long axis T1FS
If there have been previos FOLLOW UP studies which are adequate, please match slice thickness and gap to make comparison easier
Diabetic foot
Sag STIR T1
Coronal FSPD T1
Axial FSPD
If there is a soft tissue mass present ....
Coronal T1FS pre and post Gad
Extend Hindfoot FOV to include MTPJ's
If in doubt use Gad
Osteomyelitis
Long axis STIR and T1
Axial T1 and FSPD
Gad not usually needed
Soft Tissue Tumours
