Parameter estimation in Bayesian reconstruction of SPECT images: An aid in nuclear medicine diagnosis

INTERNATIONAL JOURNAL OF IMAGING SYSTEMS AND TECHNOLOGY, Issue 1 2004
Antonio López
Abstract Despite the adequacy of Bayesian methods to reconstruct nuclear medicine SPECT (single-photon emission computed tomography) images, they are rarely used in everyday medical practice. This is primarily because of their computational cost and the need to appropriately select the prior model hyperparameters. We propose a simple procedure for the estimation of these hyperparameters and the reconstruction of the original image and test the procedure on both synthetic and real SPECT images. The experimental results demonstrate that the proposed hyperparameter estimation method produces satisfactory reconstructions. Although we have used generalized Gaussian Markov random fields (GGMRF) as prior models, the proposed estimation method can be applied to any priors with convex potential and tractable partition function with respect to the scale hyperparameter. © 2004 Wiley Periodicals, Inc.

Synthesis of a technetium-99m labelled L -tyrosine derivative with the fac - 99mTc(I)(CO)3 -core using a simple kit-procedure

Abstract The synthesis of a novel technetium-99m labelled derivative of L -tyrosine as a potential tumour imaging agent for nuclear medicine diagnosis is reported. The synthesis involved the labelling precursor fac -[99mTc(OH2)(CO)3]+ which was synthesized using the commercially available Isolink® -labelling kit and the tyrosine derivative O-(N,N-bis(carboxymethyl)aminoethyl)- L -tyrosine trifluoroacetate. The labelled compound O -(99mTc(I)-tricarbonyl- N,N-bis(carboxymethyl)aminoethyl)- L -tyrosine was obtained in a radiochemical yield of 70,80% within 60 min with a radiochemical purity greater than 98% without any HPLC purification step. Purification was achieved merely by solid phase extraction. Chemical as well as chiral purity was determined using gradient- and chiral HPLC. Copyright © 2004 John Wiley & Sons, Ltd. [source]
