Objective(s): Nuclear medicine technologists in Japan often perform additional single-photon emission computed tomography (SPECT) with or without computed tomography (CT) after whole-body imaging for bone scintigraphy. In this study, we wanted to identify the bone scanning protocols used in Japan, together with the current clinical practices. Methods:...

OBJECTIVE To determine the optimal iodine concentration of contrast media for kidney multidetector computed tomography (MDCT) by comparing the degree of renal parenchymal enhancement and the severity of the renal streak artifact with contrast media of different iodine concentrations. MATERIALS AND METHODS A 16-row MDCT was performed in 15 sedated rabbits by injection of 2 mL contrast media/kg...

Melioidosis is a potentially fatal infectious disease occurring predominantly in the tropics, caused by a Gram-negative, motile, rod shaped obligatory aerobic non-spore forming bacillus, Burkholderia pseudomallei. It can produce localised or disseminated disease largely affecting immunocompromised patients. It is a challenge to identify melioidosis early as this disease can manipulate host’s ce...

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 regions to facilitate manipulation of mo...

Although the prognosis of patients with differentiated thyroid carcinoma (DTC) is generally encouraging, a diagnostic dilemma is posed when an increasing level of serum thyroglobulin (Tg) is noted, without detection of a recurrent tumor using conventional imaging tools such as the iodine-131 whole-body scanning (the [(131)I] scan) or neck ultrasonography (US). The objective of the present study...

Introduction. Although whole body scan (WBS) with I-131 is a highly sensitive tool for detecting normal thyroid tissue and metastasis of differentiated thyroid cancer (DTC), it is not specific. Additional information, provided by single photon emission computed tomography combined with X-ray computed tomography (SPECT/CT) and by the serum thyroglobulin level, is extremely useful for the interpr...

This paper describes a scheme for reconstructing 3D human models from whole-body scan data. The 3D human models are composed of superquadric primitives each corresponding to a functional body part. The reconstruction starts with primary segmentation of scan data, which defines the location of the articulation link in the human scan and results in topologically simple (primary) body parts. The p...

Accurate capture of encumbered anthropometry is critical to ensure that the analysis and design of military platforms and workspaces account for the additional space required for clothing and PPE equipment. To examine the effect of encumbrance on spatial claim, a method was developed to obtain scan-extracted measures from detailed whole-body shape data. This analysis focused on comparing cross-...

In September, 2006, a 66-year-old man was admitted to our hospital with a 6-week history of nausea, dysphagia to solids, and abdominal discomfort after eating. His appetite was much reduced, and he reported that he felt sated after eating little food; he had lost 10 kg in weight, and was constantly tired. His past medical history included hypertension, dyslipidaemia, and coronary artery disease...
