clinicadl.io.bids.PetLinear¶

class clinicadl.io.bids.PetLinear(tracer: str | Tracer, suvr_reference_region: str | SUVRReferenceRegion, reconstruction: str | ReconstructionMethod | None = None, use_uncropped_image: bool = False)[source]¶

BidsFileType to select Positron Emission Tomography (PET) images preprocessed with Clinica pet-linear pipeline.

Parameters:

tracer (str | Tracer) – The radioactive tracer used for acquisition, among 11CPIB, 18FAV1451, 18FAV45, 18FFBB, 18FFDG and 18FFMM.
suvr_reference_region (str | SUVRReferenceRegion) – The reference region used to compute SUVR, among pons, cerebellumPons, pons2 and cerebellumPons2.
reconstruction (Optional[ReconstructionMethod], default=None) – The method used to reconstruct the image, among nacstat, nacdyn, acstat, acdyn, coregdyn, coregavg, coregstd and coregiso. Leave to None if not specified.
use_uncropped_image (bool, default=False) –
Whether to use the uncropped images returned by Clinica:
- if use_uncropped_image=True: only the files that match the pattern pet_linear/sub-*_ses-*_trc-{tracer}_space-MNI152NLin2009cSym_res-1x1x1_suvr-{suvr_reference_region}_pet.nii* will be selected.
- else: only the files that match the pattern pet_linear/sub-*_ses-*_trc-{tracer}_space-MNI152NLin2009cSym_desc-Crop_res-1x1x1_suvr-{suvr_reference_region}_pet.nii* will be selected.
Note

If reconstruction is specified, the pattern will be modified as follows: pet_linear/sub-*_ses-*_trc-{tracer}_rec-{reconstruction}_space-MNI152NLin2009cSym_(desc-Crop)_res-1x1x1_suvr-{suvr_reference_region}_pet.nii*
