Diagnostic accuracy and safety of CT-guided percutaneous needle aspiration biopsy the lung: comparison small large pulmonary nodules.H Li, P M Boiselle, J O Shepard, B Trotman-Dickenson T C McLoudAudio Available | Share
Purpose To compare lesion detection and image quality of chest computed tomographic (CT) images acquired at various tube current–time products (40–150 mAs) reconstructed with adaptive statistical iterative reconstruction (ASIR) or filtered back projection (FBP). Materials Methods In this Institutional Review Board–approved HIPAA-compliant study, CT data from 23 patients (mean age, 63 years ± 7.3 [standard deviation]; 10 men, 13 women) were varying (40, 75, 110, 150 on a 64-row multidetector...
Studies have shown that some patients with coronavirus disease 2019 (COVID-19) and acute hypoxaemic respiratory failure preserved lung compliance, suggesting processes other than alveolar damage might be involved in hypoxaemia related to COVID-19 pneumonia.1Gattinoni L Coppola S Cressoni M Busana Rossi Chiumello D Covid-19 does not lead a "typical" distress syndrome.Am J Respir Crit Care Med. 2020; (published online March 30.)DOI:10.1164/rccm.202003-0817LECrossref Scopus (964) Google Scholar...
To investigate pulmonary vascular abnormalities at CT angiography (CT-PE) in patients with coronavirus disease 2019 (COVID-19) pneumonia.In this retrospective study, 48 reverse-transcription polymerase chain reaction-confirmed COVID-19 infection who had undergone CT-PE between March 23 and April 6, 2020, a large urban health care system were included. Patient demographics clinical data collected through the electronic medical record system. Twenty-five underwent dual-energy (DECT) as part of...
Purpose: To assess radiation dose reduction and image quality for weight-based chest computed tomographic (CT) examination results reconstructed using adaptive statistical iterative reconstruction (ASIR) technique. Materials Methods: With local ethical committee approval, weight-adjusted CT examinations were performed ASIR in 98 patients filtered backprojection (FBP) 54 weight-matched on a 64-slice multidetector CT. Patients categorized into 3 groups: 60 kg or less (n = 32), 61 to 90 77), 91...
Purpose To compare visualization of subtle normal and abnormal findings at computed tomography (CT) the chest for diffuse lung disease with images reconstructed filtered back projection adaptive statistical iterative reconstruction (ASIR) techniques. Materials Methods In this HIPAA-compliant, institutional review board–approved study, 24 patients underwent 64-section multi–detector row CT evaluation disease. Scanning parameters included a pitch 0.984:1 120 kVp in thin-section mode, 2496...
Wegener granulomatosis is an uncommon necrotizing vasculitis that classically manifests as a clinical triad consisting of upper and lower airway involvement glomerulonephritis. Other less frequently involved organ systems include the central peripheral nervous system large joints. The diagnosis based on combination laboratory findings. Because thoracic often predominates, chest radiographic findings are first to suggest diagnosis. However, computed tomography (CT) has superior sensitivity...
The purpose of this study was to analyze the clinical and CT features pulmonary artery pseudoaneurysms (PAPs).A database search chest examinations performed from January 1, 2000 December 31, 2014 identified 24 patients with findings consistent PAPs. A finding a PAP defined as focal saccular outpouching artery. Medical records were reviewed determine presentations, treatments, outcomes. scans by two board-certified fellowship-trained radiologists.A total 35 PAPs in patients. Hemoptysis...
The aim of the study was to investigate natural history non-small cell lung cancers (NSCLCs) associated with cystic airspaces, including histopathology and molecular analysis.A total 34,801 computed tomographic (CT) scans 2954 patients diagnosed NSCLC between 2010 2015 were evaluated for association a airspace. Characteristics on serial CT, 18F-fludeoxyglucose positron emission tomography, pathologic analysis recorded.Cystic airspaces 1% cases (12 men 18 women; median age, 66 y [range, 44 87...

Institutional review board approval of the study protocol and waiver informed consent were obtained. This was compliant with Health Insurance Portability Accountability Act. The purpose this to retrospectively assess scanning radiation dose associated z-axis automatic tube current modulation in multi–detector row CT chest. Fifty-three patients (mean age, 54 years; age range, 26–77 25 men, 28 women) underwent 16–detector chest noise indexes 10.0, 12.5, 15.0 HU. Two radiologists independently...
To study factors that may influence pneumothorax and chest tube placement rate, especially needle dwell time pleural puncture angle.In 159 patients, 160 coaxial computed tomography (CT)-guided lung biopsies were performed. Dwell time, the between removal, was calculated. The smallest angle of with pleura ("needle-pleural angle") measured. These other variables correlated rates.One hundred fifty included. There 58 (39%) pneumothoraces (14 noted only at CT), eight (5%) resulting in placement....
CT accounts for considerable population-based radiation dose from radiographic diagnostic studies. The technical factors examinations are not appropriately adjusted on the basis of patient size and anatomy. We hypothesized that doses routine chest can be reduced by 50% evaluation normal structures without seriously jeopardizing image quality.After receiving institutional review board approval, we prospectively studied 24 patients with cancer who were 65 years old older a multidetector...
