For all locally-advanced NSCLC patients
3D PET/CT with IV contrast
4D CT + short breath hold CT
Contrast if central tumour
Visual review of the 4D CT (by a dosimetrist):
if < 5mm peak-to-peak motion, plan on the PET/CT, where
contouring is most reliable
if > 5 mm peak-to-peak motion : MidVentilation
Occasional use of the ITV approach (e.g. if too many
artifacts)
