CBF¶

purpose:

CBF Computation

description:

Calculate CBF from an ASL image using CASL or PASL.

usage:

# ASLtbx

cbf_casl1_ASLtbx( aslimg_filename , m0img_filename )

cbf_casl2_ASLtbx( aslimg_filename )

cbf_pasl_ASLtbx( aslimg_filename , m0img_filename )

# Chen 2011 paper

cbf_casl_Chen2011( aslimg_filename )

cbf_pasl_Chen2011( aslimg_filename , m0img_filename )

cbf_pcasl_Chen2011( aslimg_filename )

# Wang 2012 paper

cbf_casl_Wang2012( aslimg_filename , Xvar = NULL , Xideal = NULL , c =

NULL )

# update a give CBF estimate using PASL/CASL

compute_cbf( cbf , img , method = 0 , labelfirst = 1 )

# compute robust cbf

cbf_robust( asl_img )

examples:

cbf <- cbf_casl1( "asl.nii" , "m0.nii" )cbf <- cbf_casl2( "asl.nii" )

cbf <- cbf_pasl( "asl.nii" , "m0.nii" )

# updating existing cbf estimate using CASL; method = 0 , labefirst = 1

cbf <- compute_cbf( cbf , asl_img )

# comput robust cbf of an asl image

cbf <- cbf_robust( "asl.nii" )
