Fetal Anatomy by Three-Dimensional Ultrasound

Perinatal care's primary goal is to find fetal anomalies prior to birth. Three-dimensional ultrasound is a new technology that allows for a new way to determine the fetus. However, the accurate diagnosis of fetal anomalies by this technique must be applied to specific stages of pregnancy in order to establish normal fetal anatomy. We are still searching for an image reference library of fetal anatomy by determining key diagnostic characteristics by three-dimensional ultrasound. Magnetic Resonance Imaging will investigate potential advantages and disadvantages of this imaging technique in comparison to 3DUS for the diagnosis of congenital anomalies. Three-dimensional ultrasonography will give up to 400 examples of normal fetal anatomy.

Three-dimensional (3D) Printed Hemodialysis Vascular Model for Increased Precision of Cannulation

Hemodialysis is the most common treatment for End Stage Renal Disease. A patent vascular connection is critical for an effective renal replacement therapy. The guidelines emphasize the importance of good vascular access maintenance. The importance of good vascular access monitoring has been largely promoted. Access infiltration, which is often overlooked in clinical settings, is a common cause of VA failure. Between $ 16,864 - U. S. $20,961 and more than half is due to access infiltration alone, which is attributed to the estimated financial burden attributable to the VA complication. The skill set of dialysis technician nurses plays a large part in the successful cannulation of the fistula. The 3D image reconstruction provides a cost-effective method to produce a 3D VA model that can be used by the procedurests to cannulate the patients, minimizing the risks and rates of re admissions. Overall, a significant decrease in the health care cost can be made.

Three-dimensional Bone Regeneration Using Custom-made Meshes With and Without Collagen Membrane: Randomized Clinical Trial

The use of this pre-engineered and pre-fabricated mesh with bevel margins and three-dimensionally adapted to the bone defect will result in a congruent bone regeneration, lowering the operating times, the risks related to the mesh injury, and patient discomfort. The collagen membrane in association with titanium, which is based on the principles of guided bone regeneration, could help bone growth and minimize the percentage of early and late exposure of the mesh. This research is designed to determine, in cases of maxillary and mandibular atrophies characterized by vertical and/or horizontal resorption of the algular bone, the percentage of problems after bone regeneration using custom-made mesh with or without collagen membrane. Patients will be divided into two research groups and assigned to each study group based on the previous computer-generated randomization sequence: 15 patients will be treated by bone regeneration using custom-made mesh without a collagen membrane. All of the products and equipment that will be used in the study are CE registered and have already been used in the routine care pathway for patients with bone regeneration. The primary aim of this research is to determine the non-inferiority of technique B compared to technique A in the incidence of complications. After 12 months of follow-up, bone quality analysis and peri-implant bone resorption were included among the Secondary goals included assessment of patient and operator benefits, reconstructed bone volume relative to planned bone volume, histological and histomorphometric evaluation of bone quality, and peri-implant bone resorption.

Three-dimensional MR Elastography for Assessing Cirrhosis and Portal Hypertension (CHESS2206): A Prospective Multicenter Study

China has the world's largest burden of liver disease. More than 400 million people suffer with chronic liver disease. Portal hypertension is a key risk factor that is correlated with clinical prognosis of patients with cirrhosis. According to the Consensus on the clinical use of a hepatic venous pressure gradient in China, a hepatic venous pressure gradient greater than 10,12,16,20 mmHg predicts different outcomes in patients with cirrhosis portal hypertension. HVPG prediction is a significant general issue in the treatment of portal hypertension in cirrhosis, and designing a novel, non-invasive, specific, and convenient way to do it is a common problem. Three-dimensional MR elastography can be used for basic viscoelastic modeling of tissue, partitioning the turbulent shear modulus into elastic components and viscous components. However, specific hepatic pathophysiologic interrelations have yet to be investigated in cirrhosis to identify specific hepatic pathophysiologic interrelations.

Cervical Volume by Three-Dimensional Ultrasound as a Predictor of Preterm Delivery

Several researchers have reported that ultrasound examination of the cervix can reveal preterm delivery risks. A three-dimensional ultrasound may help parents understand the risks of premature birth. Therefore, three-dimensional ultrasound techniques may be able to more accurately represent cervical changes and the danger for preterm delivery. A maximum of 680 pregnant women with the diagnosis of preterm labour will be prospectively studied to determine cervical morphology and volume as predictors of preterm delivery risk. We will also compare the results of conventional two-dimensional endovaginal ultrasound with three-dimensional ultrasound findings.
