Can the Newer Model of Breast-Specific Positron Emission Tomography Reduce the “Blind Area”? Open
Objectives: Breast-specific positron emission tomography (PET) provides higher sensitivity and spatial resolution than whole-body PET/CT, but it has a blind area. Mammary glands near the chest wall sometimes present outside the field of vi…

Assessment of Single Photon Emission Computed Tomography 123I-IMP Brain Scan Parameters Using Low Energy High Resolution Collimator and 3D Iterative Image Reconstruction Algorithm (Flash 3D) Open
Objective Statistical parametric mapping of 123I-IMP brain SPECT images has been used for brain disorders such as Alzheimer’s disease (AD) and dementia with Lewy bodies (DLB) for several decade. The analysis results highly depen…

Inter-rater agreement and variability in visual reading and of [18F]Flutemetamol PET Open
Objective: The purpose of this study was to validate the concordance of visual ratings of [18F]flutemetamol amyloid positron emission tomography (PET) images and to investigate the correlation between the agreement of each rater and the Ce…

Quantitative Evaluation of 18F-Flutemetamol PET in Patients With Cognitive Impairment and Suspected Alzheimer's Disease: A Multicenter Study Open
Background: In clinical practice, equivocal findings are inevitable in visual interpretation of whether amyloid positron emission tomography (PET) is positive or negative. It is therefore necessary to establish a more objective quantitativ…

Preliminary study of time maximum intensity projection computed tomography imaging for the detection of early ischemic change in patient with acute ischemic stroke Open
Noncontrast computed tomography (NCCT) has been used for the detection of early ischemic change (EIC); however, correct interpretation of NCCT findings requires much clinical experience. This study aimed to assess the accuracy of time maxi…
