Three Dimensional Ultrasonography of the Eye and Measurement of Optical Nerve Sheet Diameter in Dog
Objective- To determine the possibility of three-dimensional ultrasonography (3DUS) and measurement of optical nerve sheet by this method. Design- Descriptive study. Animals- 10 mixed normal dogs (5males, 5 females), age 1-1.5 year, and weighting 15±5 kg Procedure- 3D ultrasounds of the eyes were evaluated and the normal optical nerves in 3DUS images were measured using Volouson 730 pro....
متن کاملRole of MRCP in the measurement of the CBD diameter.
Several diagnostic methods such as ultrasonography, endoscopic retrograde cholangiopancreatography, and multidetector computed tomography have been used to measure the diameter of the common bile duct (CBD). Magnetic resonance cholangiopancreatography (MRCP) is a noninvasive procedure and a novel method for delineating biliary and pancreatic disorders. It requires no contrast material injection...
متن کاملRapid method for measurement of bronchial responsiveness.
A rapid, simple method for measuring bronchial responsiveness to inhaled histamine is described. The method was used to obtain dose response curves in 50 atopic subjects with varying respiratory and nasal symptoms. The cumulative dose of histamine which caused a 20% fall in the one second forced expiratory volume (PD20-FEV1) varied between 0.046 and greater than 3.9 mumol and correlated with th...
متن کاملDirect measurement of bronchial arterial flow.
THE normal bronchial arterial blood flow provides only a very small portion of the blood flow through the lungs.' 2 Since it supplies oxygen and nutrients to the bronchial musculature and mucosa, it may have importance for pulmonary mechanisms far beyond that expected on the basis of its small flow. After giving up its oxygen on passage through the pulmonary parenchyma, this flow passes into th...
متن کاملComparison of the Five Different Methods in Arterial Diameter Measurement
Background/Aims: In this study, the different types of arterial diameter measurement methods were compared with each other on rat model. Methods: The study was planned in three phases. In phase 1, all subjects (n = 30) underwent high resolution B-mode ultrasound examination and external diameter of the right common carotid artery (RCCA) was measured. In phase 2, RCCA was explored. In phase 3, r...
