Ichikawa H, Shibutani T, Kato T, Banno T, Terabe M, Shimada H
J Nucl Med Technol
. 2025 Mar;
PMID: 40037655
F-FDG PET/CT is crucial for cancer diagnosis; however, respiratory motion often causes misregistration between PET and CT images. This study aimed to evaluate the impact of a custom-made respiratory motion...

Nihon Hoshasen Gijutsu Gakkai Zasshi
. 2025 Feb;
81(4).
PMID: 39993776
Purpose: Japanese normal databases (NDB) for quantitative evaluation of Tc myocardial perfusion SPECT have traditionally been created by the filtered back projection (FBP) method but are also applied to the...

Ichikawa H, Kato T, Shibutani T, Terabe M, Shimada H
Radiol Phys Technol
. 2025 Feb;
PMID: 39966310
Patient motion, particularly due to respiration, often introduces image distortions that compromise diagnostic accuracy in myocardial perfusion single-photon emission computed tomography (SPECT). To address this issue, we developed a novel...

Asia Ocean J Nucl Med Biol
. 2025 Jan;
13(1):42-52.
PMID: 39744054
Objectives: Brain perfusion single-photon emission computed tomography (SPECT) image quality varies depending on SPECT systems. This study aimed to evaluate the relationship between physical parameters and visual analysis for assessment...

Nihon Hoshasen Gijutsu Gakkai Zasshi
. 2024 Oct;
80(11):1191-1197.
PMID: 39414426
We evaluated the effect of different xSPECT Bone acquisition methods on image quality and quantitative accuracy. A mixed bone-equivalent solution set to 250 HU and Tc was filled with the...

J Nucl Med Technol
. 2024 Jun;
52(3):247-251.
PMID: 38901966
The lack of pediatrics-specific equipment for nuclear medicine imaging has resulted in insufficient diagnostic information for newborns, especially low-birth-weight infants. Although PET offers high spatial resolution and low radiation exposure,...
