To determine the effects of iterative reconstruction (IR) and high-frequency kernels on quantitative computed tomography (qCT) density measures at reduced X-ray dose.The COPDGene 2 Phantom (CTP 698, The Laboratory, Salem, NY) with four embedded lung mimicking foam densities (12lb, 20lb, 4lb), as well water, air, acrylic reference inserts, was imaged using a GE 64 slice CT750 HD scanner in helical mode current-time products ranging from 12 to 100 mAs. raw acquired data were reconstructed...
We reduced the computed tomography (CT)-reconstructed field of view (FOV), increasing pixel density across airway structures and reducing partial volume effects, to determine whether this would improve accuracy wall thickness quantification.We performed CT imaging on a lung phantom 29 participants. Images were reconstructed at 30-, 15-, 10-cm FOV using medium-smooth kernel. Cross-sectional dimensions compared each with repeated-measures analysis variance.Phantom measurements more accurate...
To determine the impact of constrained reconstruction techniques on quantitative CT (qCT) lung parenchyma and airways for low x-ray radiation dose.Measurement small with qCT remains a challenge, especially dose protocols. Images COPDGene quality assurance phantom (CTP698, The Phantom Laboratory, Salem, NY) were obtained using GE discovery CT750 HD scanner helical scans at dose-equivalents ranging from 1 to 4.12 mSv (12-100 mA s current-time product). Other parameters 40 mm collimation, 0.984...
Abstract A 14‐year‐old Irish sport horse presented to our institution with a history of right forelimb lameness and left‐sided back pain. Radiography nuclear scintigraphy were performed under sedation the was diagnosed overriding dorsal spinous processes, also known as kissing spine syndrome. Surgical treatment consisted process ostectomy desmotomy general anaesthesia. This case report summarises perianaesthetic management, which included an erector spinae plane block part multimodal...
An English springer spaniel developed laryngeal paralysis immediately after a ventral slot decompression surgery to treat an intervertebral disc extrusion that was causing C1–T2 myelopathy with cervical hyperaesthesia. Postsurgical stabilisation in the intensive care unit is described. This included mechanical ventilation, tracheostomy tube placement and care, tie‐back aftercare. Common complications include pain, severe haemorrhage deterioration neurological status. Laryngeal has not yet...
Objectives The aim of this study was to determine the maximal endotracheal insertion length by measuring larynx carina (L–C) distance means CT. An additional objective establish certain anatomical landmarks optimise process intubation (ETI). Methods Head, neck and thoracic CT images from adult cats at a single referral hospital between 2013 2020 were retrospectively evaluated. After standardising identifying key markers (larynx, first rib) L–C, rib (L–1R) (1R–C) distances measured. Results...
Purpose: To improve the accuracy of airway measures and reduce x‐ray dose in quantitative CT (qCT) lung. Methods: qCT was performed on an phantom (COPD gene) a swine model. The used to identify expected improvements spatial resolution noise tradeoffs for choice reconstruction kernel display FOV (DFOV). Results were then applied Images obtained via helical scans that using GE Discovery CT750 HD with COPD Gene/SARP protocols except tube current varied from 790 50 mA, lung inflation fixed...
