BACKGROUND Chest CT is a commonly used examination for the diagnosis of lung diseases, but a breast within the scanned field is nearly never the organ of interest. OBJECTIVE The purpose of this study is to compare the female breast and lung doses using split and standard protocols in chest CT scanning. MATERIALS AND METHODS The sliced chest and breast female phantoms were used. CT exams wer...
H7N9 influenza is a new emerging infection and has high mortality. Both chest radiography and computed tomography (CT) had some limitations in assessing such patients. We performed daily lung ultrasound in a patient with H7N9 influenza. Lung ultrasound and lung ultrasound score showed high consistency with CT and the progression of pneumonia. Ultrasound can be adjutant to chest radiography and ...
HYPOTHESIS The use of liberal whole body imaging (pan scan) in patients based on mechanism is warranted, even in evaluable patients with no obvious signs of chest or abdominal injury. DESIGN Prospective observational study. SETTING Academic level I trauma center. PATIENTS All patients admitted following blunt multisystem trauma. INTERVENTION Pan scan, including computed tomography (CT) ...
Introduction: Rib fractures are common presentations at emergency departments across the UK. 21% of emergency admissions are related to rib fractures, resulting from up to 39% of all blunt-trauma to the chest. Imaging is essential for identification of rib fractures but also for planning potential surgical intervention. The introduction of 3D imaging has enhanced the pre-surgical planning in ma...
BACKGROUND Pneumothorax (PNX) is the collection of air between parietal and visceral pleura, and collapsed lung develops as a complication of the trapped air. PNX is likely to develop spontaneously in people with risk factors. However, it is mostly seen with blunt or penetrating trauma. Diagnosis is generally confirmed by chest radiography [posteroanterior chest radiography (PACR)]. Chest ultra...
An 83-year-old woman presented to the emergency department with a 2-hour history of sudden chest pain and dyspnea. An initial ECG demonstrated nonspecific ST changes, and a portable chest x-ray suggested a widened mediastinum. A thoracic multidetector helical computed tomography (CT) angiogram was obtained to assess the possibility of aortic dissection (GE LightSpeed Plus, 2.5-mm collimation wi...
Background: The outbreak of COVID-19 poses a major and urgent threat to global public health. CT findings associated with pneumonia from initial diagnosis until patient recovery. This study aimed retrospectively analyze abnormal lung changes following computed tomography (CT) among patients coronavirus disease 2019 (COVID-19) in Yunnan, evaluate the effectiveness chest CT-based model for COVID-...
abstract bronchoalveolar carcinoma presenting as non-resolving consolidation is an uncommon presentation. the typical presentation of bronchoalveolar carcinoma is asymptomatic (solitary nodule) and remains without symptoms even as disease disseminates. we report a case of bronchoalveolar carcinoma presenting as non-resolving consolidation in a young male with productive cough, exertional breath...
clavicular bone tumors occur in less than 0.5 percent of bone tumors. primary chondrosarcoma is very rare even among clavicle tumors. the main symptom is a touchable mass in 69 % of patients. dedicated centers using fna and cytology can reach a correct diagnosis in 94% of cases. treatment planning is done using simple x-ray, ct-scan, shoulder mri, chest ct-scan, and whole body technetium scan. ...
