Objective The aim of this pilot study was to investigate the potential early-phase single-photon emission computed tomography (SPECT)/computed (CT) using technetium-99m methyl diphosphonate (99mTc-MDP) for diagnosing osteomyelitis (OM). Materials and methods Twenty-one patients with suspected OM were enrolled retrospectively. Three-phase bone scan (TPBS), SPECT/CT (immediately after blood pool planar imaging), delayed-phase delayed imaging) performed. final diagnoses established through...

The human facial skeleton consists of multiple segments and causes difficulty during analytic processes. We developed image analysis software to quantify the amount injury validate smooth curvature surface after bone reduction surgery. Three-dimensional computed tomography images were obtained from 40 patients who had undergone open surgery treat unilateral zygomaticomaxillary fractures. Analytic was based on discrete a triangular mesh model. values compared before using two regions...

In this paper, we proposed an efficient coding method for digital hologram (fringe pattern) acquired with a CCD camera or by computer generation using multi-view prediction and MPEG video compression standard techniques. It processes each R, G, B color component separately. The basic processing unit is partial image segmented as the size of M × N. Each retains information whole object. This generates assembled column frequency-transformed images, which basis process. That is, motion...

Increased 67Ga uptake in the mediastinal/hilar lymph nodes ("lambda") and lacrimal/parotid/submandibular glands ("panda") often coexists patients with sarcoidosis (Sarc-Pts). However, we observed that increased lacrimal/salivary is uncommon on 18F-FDG PET/CT (FDG-panda) many Sarc-Pts who showed (FDG-lambda). We evaluated parotid lacrimal FDG activity FDG-lambda comparison a control patient group attempted to find underlying mechanisms explain discrepancy between Ga these organs.Parotid...

In this study we evaluated the relationship between amyloid-beta (Aβ) deposition and 3 aspects of sleep quality in a group clinically diagnosed Alzheimer's disease (AD) patients.We used self-report questionnaires to assess using previously established surveys: Glasgow Sleep Effort Scale (GSES), Pittsburgh Quality Index (PSQI), Morningness-Eveningness Questionnaire (MEQ). These focused on effort, efficiency, circadian rhythm patterns each participant. Also, regional distribution Aβ brain by...

Background and Objectives: The optimal assessment of cognitive function, including the impact education, is crucial in managing Alzheimer’s disease (AD). This study aimed to evaluate role reserve (CR), represented by metabolic status regions cerebral cortex, decline considering educational attainment patients with AD. Materials Methods: We used data from Disease Neuroimaging Initiative database, selected 124 who underwent both baseline F-18 fluorodeoxyglucose (FDG) florbetaben (FBB) positron...

Background and Objectives: 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET) (PETFDG) image can visualize neuronal injury of the brain in Alzheimer’s disease. Early-phase amyloid PET is reported to be similar PETFDG image. This study aimed generate images from 18F-florbetaben (PETFBB) using a generative adversarial network (GAN) compare generated (PETGE-FDG) with real (PETRE-FDG) structural similarity index measure (SSIM) peak signal-to-noise ratio (PSNR). Materials Methods:...

Abstract This paper proposes a method of extracting regions car number plates using parameter‐restricted Hough transformation (PRH). The PRH algorithm, in which the range parameter plane is restricted, reduces computation time and storage capacity more effectively than usual transformation. In this method, some features are used.

It is often challenging to assess renal activity on FDG-PET/CT due intense physiological in the collecting system, thus any unusual intrarenal should be evaluated carefully. While increased bone tracer uptake irradiated region of kidneys has been reported literature, altered biodistribution FDG tissue not well described. We report a case PET/CT showing small portions that were previously irradiated.

Background and Objectives: Unstable thoracolumbar burst fractures require surgical management as they can result in neurological deficits if left untreated. This study aimed to evaluate whether a new bone scan scoring system could accurately assess instability fractures. Materials Methods: Fifty-two patients with who underwent scans magnetic resonance imaging prior surgery between January 2015 August 2017 at Ulsan University Hospital were selected for inclusion. Instability was determined by...

Presence of biliary stent may alter dynamics, which change the results cholescintigraphy. We assessed frequency gallbladder (GB) nonvisualization and its specificity for acute cholecystitis (AC) in patients with stent.Of 44 who had cholescintigraphy, 22 were excluded because prior cholecystectomy or little to no radiotracer excretion from liver precluding assessment GB filling. Cholescintigraphy performed on remaining their medical records reviewed. also comparison group 1044 without...

Abstract We describe a case of adenomyosis that reduced in size patient with lymphoma on receiving chemotherapy. A 48-year-old woman worsening left flank pain was diagnosed follicular lymphoma. [ 18 F]FDG PET/CT revealed multiple hypermetabolic lymph nodes the bilateral cervical, axillary, mediastinal, mesenteric, retroperitoneal, iliac, and inguinal regions. In addition, mild hypermetabolism demonstrated PET/CT. The metabolism decreased after chemotherapy R-bendamustine; along decrease...

Abstract Previously, the authors proposed a method of extracting region vehicle number‐plate using Hough transformation with restricted parameter plane. The offers significant reduction amounts memories and their processing time which are required for storing plane in conventional transformation. This paper describes further improvement its speed. In processing, first, pyramid hierarchy is applied to original image; second, some preliminarily selected straight lines extracted from image...

In this paper, we propose an enhanced signal to interference ratio (SIR) measurement algorithm and evaluate the performance of proposed in a WCDMA forward link receiver with closed-loop fast transmit power control. The reduces measured SIR offset by using pilot channel (CPICH) compensate for attenuated fading environment. outperforms conventional regard mean values jitter, especially high speed mobile Also, results closed loop control show that has better than algorithm.
