OBJECTIVE: Although IQ-single-photon emission computed tomography (SPECT) provides rapid acquisition and attenuation-corrected images, the unique technology may create characteristic distribution different from the conventional imaging. This study aimed to compare the diagnostic performance of IQ-SPECT using Japanese normal databases (NDBs) with that of the conventional SPECT for thallium-201 ((201)Tl) myocardial perfusion imaging (MPI). METHODS: A total of 36 patients underwent 1-day (201)Tl adenosine stress-rest MPI...

OBJECTIVE: One of the major causes of diabetes and obesity is abnormality in glucose metabolism and glucose uptake in the muscle and adipose tissue based on an insufficient action of insulin. Therefore, many of the drug discovery programs are based on the concept of stimulating glucose uptake in these tissues. Improvement of glucose metabolism has been assessed based on blood parameters, but these merely reflect the systemic reaction to the drug administered. We have conducted basic studies to investigate the usefulness of glucose uptake measurement in various muscle and adipose tissues in pharmacological tests using disease-model animals...

OBJECTIVE: Dopamine transporter (DAT) imaging with [(123)I]FP-CIT (DaTSCAN) is a widely used diagnostic tool for Parkinsonism and dementia. Since it was approved by the Japanese Ministry of Health, Labor, and Welfare in 2013, there have been no articles focusing on a Japanese normal population. The aim of this study was to examine the effect of aging and gender on DAT availability in Japanese people. METHODS: SPECT imaging of 30 healthy Japanese controls (17 males, 13 females; range 50-86 years, mean 70 years) was performed...

PURPOSE: Apical wall thickening with an "ace-of-spades" configuration is a unique sign of apical hypertrophic cardiomyopathy (AHCM). We investigated spade-shaped FDG uptake around the left ventricular apex (SSUA) incidentally found in routine oncological FDG PET. METHODS: Cases showing SSUA were selected based on retrospective review. The pattern or intensity of SSUA was compared with the results of electrocardiogram (ECG), echocardiography, and stress myocardial perfusion SPECT...

OBJECTIVE: It is widely known that there is low striatal (123)I-FP-CIT dopamine transporter-single photon emission tomography (DAT-SPECT) uptake in patients with dementia with Lewy bodies (DLB). We assessed the correlation between symptom and regional low DAT uptake in the striatum. METHODS: Patients with Alzheimer's disease (AD) (n = 95) and patients with DLB (n = 133) who underwent DAT-SPECT were enrolled. We examined the correlation between symptoms [cognitive function decline, fluctuations, visual hallucinations, parkinsonism, and REM sleep behavior disorder (RBD)] and regional striatal DAT uptake in the patients with DLB...

Vahid Moslemi, Mansour Ashoor
OBJECTIVE: In addition to the trade-off between resolution and sensitivity which is a common problem among all types of parallel hole collimators (PCs), obtained images by high energy PCs (HEPCs) suffer from hole-pattern artifact (HPA) due to further septa thickness. In this study, a new design on the collimator has been proposed to improve the trade-off between resolution and sensitivity and to eliminate the HPA. METHODS: A novel PC, namely high energy extended PC (HEEPC), is proposed and is compared to HEPCs...

Objectives In PET studies for neuroreceptors, tracer kinetics are described by the two-tissue compartment model (2-TCM), and binding parameters, including the total distribution volume (V T), non-displaceable distribution volume (V ND), and binding potential (BPND), can be determined from model parameters estimated by kinetic analysis. The stability of binding parameter estimates depends on the kinetic characteristics of radioligands. To describe these kinetic characteristics, we previously developed a two-phase graphic plot analysis in which V ND and V T can be estimated from the x-intercept of regression lines for early and delayed phases, respectively...

OBJECTIVE: (11)C-Pittsburgh compound-B ((11)C-PIB) positron emission tomography (PET) is used to visualize and quantify amyloid deposition in the brain cortex in pathological conditions such as Alzheimer's disease (AD). Intense (11)C-PIB retention is also observed in the white matter (WM) of both healthy individuals and AD patients. However, the clinical implications of this retention in brain WM have not been clarified. We investigated the relationship between the extent of white matter lesions (WMLs) and the binding potential of (11)C-PIB (BPND) in the WM in patients with hypertensive small vessel disease...

OBJECTIVE: The tumour-to-normal ratio (T/N) is a representative index reflecting brain tumour activity by (18)F-fluorodeoxyglucose (FDG) and (11)C-methionine (MET) PET. We proposed a new automated method of calculating the normal reference value (N-value) for use as the denomination of T/N. This method uses voxel-based analysis of FDG- and MET-PET images. We compared the results of this method with those of the standard region-of-interest (ROI) method. METHODS: Data sets were obtained from 32 patients with newly diagnosed glioma and 13 patients with recurrent brain tumour...
