UNLABELLED The imaging of dopamine transporter (DAT) with (99m)Tc-TRODAT-1 ([2-[[2-[[[3-(4-chlorophenyl)-8-methyl-8-azabicyclo[3,2,1]oct-2-yl]methyl](2-mercaptoethyl)amino]ethyl]amino]ethanethiolato(3-)-N2,N2',S2,S2']oxo-[1R-(exo-exo)]-(99m)Tc-technetium) and SPECT has been recently proposed to be a valuable and feasible means of assessment of the integrity(More)
Bone scintigraphy helps to detect sacroiliitis before the radiographic changes. Nuclear medicine physicians interpret lesion on sacroiliac joint by the aid of sacroiliac joint-to-sacrum uptake ratios (sacroiliac joint index, SII). Usually, the SII is measured by manually drawing regions of interest (ROI) over the sacroiliac joints and sacrum, which is a(More)
AIM Obsessive-compulsive disorder (OCD) is a chronic disabling neuropsychiatric disorder. Current treatment modalities, such as pharmacological and behavioral methods, are sometimes unsatisfactory. The mesolimbic dopaminergic pathway is supposed to have a role in the pathogenesis of OCD. In this study, L-3,4-Dihydroxy-6-[F-18]fluorophenylalanine (F-18(More)
Background: Fluorine-18-2-deoxy-D-glucose ([ 18 F]FDG) has been widespread used in tumor detection. This study investigated the dynamic accumulation and the distribution of [ 18 F]FDG in human thyroid cancer bearing nude mice with INER ARO-PET (Animal Rotating PET) scan and autoradiography. Methods: Human thyroid cancer cells were subcuta-neously inoculated(More)
Bone extraction and division can enhance the accuracy of diagnoses based on whole-body bone SPECT data. This study developed a method for using conventional SPECT for automatic recognition of the vertebral column. A novel feature of the proposed approach is a novel "bone graph" image description method that represents the connectivity between these image(More)
Musicogenic epilepsy is a relatively rare form of epilepsy. In its pure form, it is characterized by epileptic seizures that are provoked exclusively by listening to music. The usual type of seizure is partial complex or generalized tonic-clonic. Precipitating factors are quite specific, such as listening to only one composition or the actual playing of(More)
A 54-year-old male oropharynx cancer patient received a whole body 18 F-fluorodeoxyglucose (FDG) integrated positron emission tomography/computed tomography (PET/CT) scan for pre-operative cancer staging. In addition to the oropharynx lesion, another esophageal focal lesion and right lower lung diffuse lesion were demonstrated in the FDG PET/CT scan. The(More)
Evaluation of scoliosis is performed traditionally by means of standing posterior-anterior radiographs of the full spine to assess lateral curvature with the Cobb method. In this paper, we present a new automatic algorithm to measure Cobb angle by using nuclear medicine whole body bone scan images. Our algorithm design is based on the fuzzy sets histogram(More)
Lymph node status is a main factor in determining the stage, suitable therapy and outcome in patients with breast cancer. It is therefore of clinical importance to accurately identify all sentinel lymph nodes (SLNs) for each individual tumor before surgery. Composite Single-Photon Emission Computed Tomography and Computed Tomography (SPECT/CT) scanner has(More)
