OBJECTIVE: An iterative reconstruction method in combination with resolution recovery, attenuation and scatter corrections (IR-RASC) can improve image quality. It, however, is undetermined whether this technique can improve the detection of coronary artery disease (CAD) when automated quantitative analysis is used. This study evaluated diagnostic values of IR-RASC in combination with automated quantitative analysis in stress myocardial perfusion imaging (MPI) in the CAD detection. METHODS: This study enrolled consecutive 64 patients (mean age 66...

OBJECTIVE: Patients presenting with cystic lesions in the neck without obvious signs of malignancy constitute a diagnostic challenge since fine needle aspiration is often insufficient and a diagnosis may not be reached until surgical resection/biopsy is performed. The differential diagnosis of a cystic cervical mass comprises a variety of benign conditions, but malignancy must be ruled out. We examined the diagnostic performance of fluorine-18 fluorodeoxyglucose ((18)F-FDG) PET/CT to identify malignancy...

OBJECTIVE: Distribution of PET tracer uptake is elaborately modeled via a general equation used for solute transport modeling. This model can be used to incorporate various transport parameters of a solid tumor such as hydraulic conductivity of the microvessel wall, transvascular permeability as well as interstitial space parameters. This is especially significant because tracer delivery and drug delivery to solid tumors are determined by similar underlying tumor transport phenomena, and quantifying the former can enable enhanced prediction of the latter...

OBJECTIVE: With the advent of regenerative/cell therapy for Parkinson's disease (PD), (18)F-FDOPA has drawn new attention as a biomarker of the therapeutic that cannot be evaluated with radiopharmaceuticals for dopamine transporter. Since most previous (18)F-FDOPA PET studies were carried out many years ago with a PET scanner of lower resolution and with (18)F-FDOPA of low specific activity synthesized from (18)F-F2, we used a newer PET/CT scanner with a high-resolution condition and (18)F-FDOPA synthesized from (18)F-F(-) to re-evaluate this technique on normal subjects and patients with PD, together with D2 receptor imaging with (11)C-raclopride (RAC)...

OBJECTIVE: (11)C-Methionine (MET) positron emission tomography (PET) imaging is a valuable technique for the evaluation of primary and recurrent brain tumors. Many studies have used MET-PET for data acquisition starting at 20 min after the tracer injection, while others have used scan initiation times at 5-15 min postinjection. No previous studies have identified the best acquisition timing during MET-PET imaging for suspected recurrent brain tumors. Here we sought to determine the optimal scan initiating timing after MET administration for the detection of recurrent brain tumors...

BACKGROUND: Evolutions in hardware and software PET technology, such as point spread function (PSF) reconstruction, have been shown to improve diagnostic performance, but can also lead to important device-dependent and reconstruction-dependent variations in standardized uptake values (SUVs). This may preclude the multicentre use of SUVs as a prognostic or diagnostic tool or as a biomarker of the early response to antineoplastic treatments. This study compared two SUV harmonization strategies using a newer reconstruction algorithm that improves lesion detection while maintaining comparability with older systems: (1) the use of a second reconstruction compliant with harmonization standards and (2) the use of a proprietary software tool (EQ...

AIMS: Cardiac sarcoidosis (CS) can be diagnosed using (18)F-FDG-PET/CT (PET), cardiovascular magnetic resonance (CMR), and (123)I-BMIPP/(201)TlCl dual myocardial SPECT. This study aims to clarify the relationships among the three modalities with respect to CS. METHODS AND RESULTS: We evaluated 16 patients (male n = 11; age 55 ± 13 years) with confirmed CS who underwent PET, CMR, and dual SPECT with gated SPECT before starting steroid therapy. The left ventricular myocardium was divided into 17 segments to obtain SUVmax for PET images, defect scores from 0 to 4 (0 normal; 4 absent), and mismatch scores for dual SPECT (BMDS, TLDS, and MS) images and late gadolinium enhancement (LGE) scores (0 none; 1 partly positive; 2 homogeneous) on CMR images...

OBJECTIVES: Hypoxia is a key element involved in the development and progression of tumors. HIF-1α may transiently induce and mediate the response to acute and severe hypoxia, while HIF-2α may induce a longer response and may control the response to chronic and moderate hypoxia. Hypoxia increases the cellular uptake of FDG. Therefore, HIF may play an important role in the process of the cellular uptake of FDG. The aim of this study was to compare HIF-1α/HIF-2α expression with FDG uptake, Glut-1 expression, and prognosis in the patients with lung adenocarcinoma and to investigate the role of HIF-1α/HIF-2α in the uptake of FDG in lung adenocarcinoma...

OBJECTIVES: In boron neutron capture therapy (BNCT) for cancer, the accurate estimation of (10)B tissue concentrations, especially in neighboring normal organs, is important to avoid adverse effects. The (10)B concentration in normal organs after loading with (10)B, however, has not been established in humans. In this study, we performed 4-borono-2-[(18)F]-fluoro-phenylalanine ((18)FBPA) PET in healthy volunteers and estimated the chronological changes in the (10)B concentrations of normal organs...
