Towards Automatic Detection of Enlarged Parathyroid glands in 3D Images of 99mTc-MIBI / 99mTc-pertechnetate SPECT/CT
Abstrakt
The aim of the study was to extend application of principal component analysis (PCA) of simultaneously recorded 99mTc-MIBI/123-iodine parathyroid scintigraphy to 99mTc-MIBI/99mTc-pertechnetate (MIBI/Tc) image pairs obtained in two separate examinations recorded at diferent times. Additional difculty was accurate and reproducible positioning of the patient under the camera, subsequent image registration, identifcation of residual misregistration artefacts and their diferentiation from pathological lesions of parathyroid glands.
