SPECT/CT has made it possible to perform attenuation correction easily. However, CT-
based attenuation correction (CTAC) is overestimated when metal is inside the body. The …

Background In hip resurfacing arthroplasty a metal implant (prosthesis) is used to resurface
the patient's native femoral head. The assessment of bone function around theimplant is …

Background To determine if metal artefact reduction (MAR) combined with a priori
knowledge of prosthesis material composition can be applied to obtain CT-based …

This study aims to determine the effect of Gaussian filter size for CT-based attenuation
correction (CTAC) on the quantitative assessment of bone SPECT. An experiment was …

Objective This study aimed to evaluate the effect of the metal artifact reduction (MAR)
method on quantitative single-photon emission computed tomography (SPECT)/computed …

Purpose Metallic prosthetic replacements, such as hip or knee implants, are known to cause
strong streaking artefacts in CT images. These artefacts likely induce over-or …

Background Metal artefact reduction (MAR) techniques still are in limited use in positron
emission tomography/computed tomography (PET/CT). This study aimed to investigate the …

Purpose: PET/CT performed CT-based attenuation correction generates the beam
hardening artifact by metallic implant. The attenuation correction causes over or …

Background Evidence has shown the clinical usefulness of measuring the metastatic tumor
burden of bone for prognostic assessment especially in prostate cancer; quantitative …

Objective To evaluate the impact of radiation dose reduction on image quality in patients
with metal-on-metal total hip arthroplasties (THAs) using model-based iterative …
