and therapeutic utility when evaluating new radiopharmaceuticals for use in nuclear …

In this review of the literature and general practice in the use of radiopharmaceuticals for
therapy, an argument is provided to demonstrate that the use of patient-individualized …

This paper presents a systematic analysis of the inherent uncertainty in internal dose
calculations for radiopharmaceuticals. A generic equation for internal dose is presented, and …

The goal of this study was to determine the quantitative accuracy of our OSEM-APDI
reconstruction method based on SPECT/CT imaging for Tc-99m, In-111, I-123, and I-131 …

Using iodine-123 labelled radiotracers, the presence of 2.5% high-energy photons causes
image deterioration due to increased scatter. To investigate the influence of these photons …

Radiation dose calculations in nuclear medicine depend on quantification of activity via
planar and/or tomographic imaging methods. However, both methods have inherent …

Background Quantitative accuracy in iodine 123 studies may be impaired by septal
penetration. We evaluated the effect of collimator choice on estimation of the heart …

Dual-isotope imaging can allow simultaneous assessment of brain perfusion using a 99mTc-
labeled tracer and neurotransmission using an 123I-labeled tracer. However, the images …

Background Septal penetration of high-energy photons may degrade the quality of single
photon emission computed tomography (SPECT) of the heart with iodine 123-labeled …

Septal penetration of high-energy photons affects quantitative results in imaging of 123I-
labeled tracers. We investigated acquisition protocols (collimator choice and energy window …
