Development of High-Precision Three-Dimensional Images for Colonoscopy

Background: For three-dimensional image analysis, SYNAPSE VINCENT (Fujifilm, Japan) has been applied. Authors have continued various clinical practice and research with image study by computer analysis. Patient and Method: The patient is a 65-year-old female with further evaluation of colon. Method included abdominal computed tomography (CT) scan associated with injecting necessary amount of air from the anus. With maintaining this condition, CT scan was conducted two times of supine position and prone position. Results: The case had sigmoid cancer, which was presented irregular surface texture. Further, she had colon polyp in the sigmoid colon and diverticula in the descending colon. These images were presented in the display associated with i) the position and direction for observation, ii) CT image of the corresponding point, iii) endoscopic image for the corresponding region. Discussion: This image analysis system would be useful for clinical diagnosis, because the images have multiple angles and related situations of colon mucosa, folds, and stiffness and so on. The combined data can provide significant information including coronal, horizontal and sagittal planes. When the surgeon operates colon cancer, he can make the correct imagination of the lesion in advance. It seems to be beneficial for smooth treatment of surgical operation

Augmentation of Articulate Data using 3D Image Analysis

Background: Recently, the development of information and communication technology (ICT) has been remarkable utilizing artificial intelligence (AI) technology with deep learning. Three-dimension (3-D) image analysis technology has developed using computerized tomography (CT), magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA). Among them, SYNAPSE VINCENT system (Fujifilm, Japan) is known for its predominance. Patient and Method: The patient is a 52-year-old female with type 2 diabetes mellitus (T2DM), who was suspected to have space occupying lesion (SOL) in the right kidney. Method included the investigation of enhanced abdominal CT with analysis of SYNAPSE VINCENT. Results: The detail analysis showed some findings as follows: i) coronal view of bilateral kidney shows well-enhanced left adrenal tumour, no apparent of right renal tumour, and atrophy of renal cortex, ii) the image rotated 30 degrees showed same findings, iii) the image rotated 180 degrees also showed atrophy of reverse side of right kidney. Discussion: In this case, the background of the atrophy of renal cortex has not been apparent, but it might be from diabetic nephropathy (DN). The application of VINCENT has expanded to various organs, such as liver, pancreas, biliary tract, and others, expecting augmentation of articulate data using 3D image analysis

Precise Investigation for Diabetic Patient with Recurrent Stroke by the Reconstruction Image of SYNAPSE VINCENT

Background: For recent radiological development, three-dimension (3-D) reconstruction image analysis has been in focus. Patient and Method: The patient is a 63-year-old male with type 2 diabetes (T2D) and recurrent cerebral vascular accident (CVA). The computed tomography (CT) data were analyzed by SYNAPSE VINCENT system. Results: Carotid artery and bone are simultaneously synthesized into an image. Precise image of right carotid artery was freely rotated in 0-110 degrees, in which the stenosis with calcification was detected at the bulbus of carotid artery. Discussion: Consequently, this technique and evaluation method would be beneficial for diagnosis and treatment, expecting future development

Detail Analysis of Peripheral Artery Disease (PAD) Using SYNAPSE VINCENT Technology

Background: Information and communication technology (ICT) has been developed remarkably with artificial intelligence (AI) and three-dimensional reconstruction image analysis. Patient and Method: The patient is an 84-year-old male with type 2 diabetes (T2D). The computed tomography (CT) data were analyzed by the application of SYNAPSE VINCENT system. Results: His ankle brachial index (ABI) showed 1.16/0.65 (right/left) with large difference as peripheral artery disease (PAD). He showed calcification of aorta calcification, the occlusions of left superficial femoral artery (SFA) and right tibial artery. Discussion: This technique can provide detail images, which contribute much for patients with arteriosclerotic cardiovascular disease (ASCVD)

A perspective on SIDS pathogenesis. The hypotheses: plausibility and evidence

Several theories of the underlying mechanisms of Sudden Infant Death Syndrome (SIDS) have been proposed. These theories have born relatively narrow beach-head research programs attracting generous research funding sustained for many years at expense to the public purse. This perspective endeavors to critically examine the evidence and bases of these theories and determine their plausibility; and questions whether or not a safe and reasoned hypothesis lies at their foundation. The Opinion sets specific criteria by asking the following questions: 1. Does the hypothesis take into account the key pathological findings in SIDS? 2. Is the hypothesis congruent with the key epidemiological risk factors? 3. Does it link 1 and 2? Falling short of any one of these answers, by inference, would imply insufficient grounds for a sustainable hypothesis. Some of the hypotheses overlap, for instance, notional respiratory failure may encompass apnea, prone sleep position, and asphyxia which may be seen to be linked to co-sleeping. For the purposes of this paper, each element will be assessed on the above criteria
