Filter by:This observational study aims to calculate the prevalence of conditions or diseases requiring immediate medical attention in CTC scans with an indication of bleeding post trauma performed in the ED at Odense University Hospital. Secondary, we aim to evaluate the Scandinavian Neurotrauma Committee clinical guideline 2013 for minor head injury.
This study examines the effect of music during computed tomography in children. This study, conducted on a total of 60 children, was divided into two groups: the music group and the control group. According to the research results; showed that music reduces fear and anxiety levels in children and stabilizes vital signs (pulse and respiratory rate) during a tomography scan.
A total of 9269 adults who received CCTA scans for coronary disease evaluation during a general medical checkup at the Health Screening and Promotion Center in Asan Medical Center, Seoul, Korea between January 2007 and December 2011 were initially selected. All participants were provided with information about the potential benefits and risks of CCTA and made the decision to undergo the procedure at their own expense. They were also informed that their clinical and radiological data would be used for this study and gave their consent. Of these individuals, 7129 agreed to participate, and 6343 were enrolled in this CCTA registry.
The purpose of this study is to assess the degree of sarcopenia by CT and to analyze its association with morbidity and mortality after esophagectomy and / or total gastrectomy. It is also intended to analyze the association between the degree of the CT-guided sarcopenia and the nutritional status of the patients evaluated by clinical parameters, both preoperative and postoperative. Besides that, to verify the association between the degree of sarcopenia and body fat rate.
Dacryocystitis and nasolacrimal duct obstruction are the main common causes of epiphora. Dacryocystorhinostomy (DCR) is a widely used and effective treatment for dacryocystitis and nasolacrimal duct obstruction. Among these cases, some patients have space-occupying lesions in the lacrimal sac area, such as dacryoliths, mucoceles, granulomas, and even tumors. For patients with lacrimal sac tumors, a more complex treatment plan needs to be adopted, and the severity of the disease and the complexity of treatment should be informed before surgery, since more than 55% of lacrimal sac tumors are malignant. Therefore, preoperative diagnosis and identification of lacrimal sac space-occupying lesions is important. For lack of imaging examinations, and the symptoms of patients with space-occupying lesions are often similar to those of dacryocystitis and nasolacrimal duct obstruction, which lead to the diagnosis of lacrimal sac space-occupying lesions was not discovered before DCR. CDU has been used for the observation of lacrimal gland tumors. This study has attempted to assess the CDU and CT dacryocystography characteristics of the lacrimal sac space-occupying lesions.
In thoracic surgery, one-lung ventilation using a double-lumen tube (DLT) is often performed to protect dependent lung and provide comfortable surgical conditions. However, serious complications and adverse events can be encountered during DLT placement. One of the most important steps to avoid these drawbacks is to choose the appropriate size of DLT. The width of the trachea can be measured by using different imaging methods such as computed tomography (CT) and ultrasonography (US) to predict the appropriate DLT size. CT can also contribute to the proper placement of DLT by giving us the length of the trachea and main bronchi. In this study, we hypothesized that the size of the DLT can be determined more accurately by measuring the trachea diameter by using US and CT before DLT intubation. At the same time, we aimed to determine whether the evaluation of tracheobronchial anatomy with CT would contribute to the placement of DLT at a more appropriate level.
Thymoma is the most common primary tumor of the anterior mediastinum. Complete surgical resection is the mainstay of treatment of these tumors. The staging and histological classification of thymoma is still a matter of discussion. Preoperative computed tomography (CT) scan parameters that correlate with histology, stage and prognosis also still have to be completely assessed. The aim of this study is to evaluate the potential association between clinical, radiologic and pathologic characteristics in patients submitted to surgical treatment for thymoma, assessing their prognostic value. Data of patients submitted to surgical resection for pathologically proven thymoma at our Department of Thoracic Surgery between January 2005 and December 2015 will be retrospectively reviewed. The correlation of preoperative CT scan features, histological and pathological characteristics of thymomas will be evaluated, assessing the prognostic role of these factors.
In the SARS-CoV2 pandemic, imaging studies proved its diagnostic utility to determine the severity of lung involvement. Computed tomography (CT) is a state-of-the-art study proven to be a highly sensitive diagnostic test complemented by RT-PCR testing to determine the disease and the degree of severity. In March 2020, the Dutch Society of Radiology developed a standardized assessment scheme for COVID-19 lung disease, called CO-RADS. This system proposes a level of suspicion of pulmonary involvement of COVID-19, based on the simple chest tomography findings. The level of suspicion ranges from very low (CO-RADS 1) to very high (CO-RADS 5), with two additional categories involving a technically deficient study (CO-RADS 0) and a positive RT-PCR test for SARS -CoV-2 known before tomography (CO-RADS 6). For its part, acute respiratory damage secondary to SARS-COV2 pneumonia causes acute respiratory distress syndrome, which warrants immediate medical attention. During the evaluation and triage of patients with suspected or confirmed SARS-COV2 infection, it is a challenge for health personnel given that the severity and clinical presentation is highly variable. The patient's risk stratification is carried out using previously established and validated risk scales and is a fundamental tool for making clinical decisions. Some of the risk indices and scales have been developed and used in the pandemic epicenters, such as China and Europe. Useful for the clinician is the national early warning scale (NEWS 2), severe disease risk assessment score (COVID-GRAM), the rapid severity index for COVID-19 (qCSI), evaluation score of Modified sequential organ failure (mSOFA), the sepsis-induced coagulopathy score (SIC), the ROX index as a predictor of success to the high-flow nasal cannula. The evaluation of the risk of thrombotic complications such as the Padua risk, of cardiac complications such as QT segment prolongation, through the Tisdale risk score. Risk stratification is essential in the current COVID-19 pandemic situation; upon admission, the clinician will discern if the patient requires in-hospital medical treatment, the risk of severe disease, and progression to assisted mechanical ventilation. This work aims to establish whether the severity of the findings identified by cardiac tomography upon admission and the risk established by the different established prognostic indices.
This study evaluates the depth of anatomical landmarks required in regional anaesthesia to perform either Femoral Nerve Block or PENG Block. Measures will be performed on abdominal and pelvic computed tomography as part of daily routine patient care.
The ULYSSES study is a single-center, prospective study aimed at evaluation of myocardial ischemia using regadenoson low-dose dynamic computed tomography myocardial perfusion imaging (CTP) in patients diagnosed with intermediate coronary artery stenoses in referrence to the magnetic resonance myocardial perfusion imaging (MR MPI).
