Electrical Impedance Tomography in ARDS
Acute respiratory distress syndrome (ARDS) is a clinical entity that acutely affects the lung parenchyma, and is characterized by diffuse alveolar damage and increased pulmonary vascular permeability. Currently, computed... read more
Chest Radiography vs. Lung Ultrasound for Identification of ARDS
For the identification of acute respiratory distress syndrome (ARDS) using the Berlin definition, both chest radiography and lung ultrasound were equally related to mortality. The Berlin definition using lung ultrasound helped... read more
Travel Times Affect Neurocritical Care Unit Nurse Staffing Levels
For specialist nurses on neurocritical care units, accompanying patients for imaging scans and other procedures has a major impact on nurse staffing ratios, reports a study in the Journal of Neuroscience Nursing. Over 30... read more
Pheochromocytoma Diagnosis
Pheochromocytoma is a catecholamine-producing tumor that originates from chromaffin cells of the adrenergic system, most commonly in the adrenal medulla. There are two main steps in the diagnosis of pheochromocytoma: biochemical... read more
Measuring and Monitoring Lean Body Mass in Critical Illness
Methods to monitor lean body mass in the ICU are under constant development, improving upon bedside usability and offering new modalities to measure. This provides clinicians with valuable markers with which to identify patients... read more
Airway Pressure-time Curve Profile Detects Tidal Recruitment/Hyperinflation
Airway pressure-time curve profile (stress index) detects tidal recruitment/hyperinflation in experimental acute lung injury. Shape of the Paw-t curve detects tidal recruitment and tidal hyperinflation. Pulmonary computed... read more
Variation of Poorly Ventilated Lung Units Measured by EIT to Dynamically Assess Recruitment
Assessing alveolar recruitment at different positive end-expiratory pressure (PEEP) levels is a major clinical and research interest because protective ventilation implies opening the lung without inducing overdistention.... read more
Human Airway Branch Variation and COPD
Susceptibility to chronic obstructive pulmonary disease (COPD) beyond cigarette smoking is incompletely understood, although several genetic variants associated with COPD are known to regulate airway branch development. We... read more
Regional Variation of Computed Tomographic Imaging and the Risk of Nephrectomy
In this analysis of 306 hospital referral regions, regional CT risk was significantly correlated with nephrectomy, and scanning an additional 1000 Medicare beneficiaries was associated with 4 additional nephrectomies. Beneficiaries... read more
Study suggests a new tool for diagnosing post-concussion syndrome
Unlike more common diagnostic tools, including magnetic resonance imaging and computerized axial tomography scan, diffusion tensor imaging, or DTI, effectively scans for micro abnormalities that may often go undetected by... read more
Primary Stroke Center Protocol for Suspected Stroke by Large-Vessel Occlusion
In this cohort study, when the PSC protocol was fully executed, the rate of good outcomes was doubled and the time from arrival at the PSC to reperfusion at the CSC was almost 1 hour less than that with only a partial execution... read more
Acute Kidney Injury is not Associated with IV Contrast Use in the ED
Intravenous (IV) iodinated contrast media is used routinely to improve the accuracy of computed tomography (CT) in the emergency department (ED). Prior studies have linked contrast media with the development of acute kidney... read more
Cholesteryl Ester Crystals in Lysosomal Acid Lipase Deficiency
Deficiency of lysosomal acid lipase is a rare autosomal recessive lysosomal storage disease characterized by the accumulation of cholesteryl esters and triglycerides, predominantly in macrophages. Nonspecific clinical features... read more
Skeletal muscle quality as assessed by CT-derived skeletal muscle density is associated with 6-month mortality in mechanically ventilated critically ill patients
Low skeletal muscle quality at ICU admission, as assessed by CT-derived skeletal muscle density, is independently associated with higher 6-month mortality in mechanically ventilated patients. Thus, muscle quality as well... read more
CT said to be 'effective gatekeeper' for coronary angiography
Study found the length of stay was shortened by 22.9 hours with CT, and patients preferred noninvasive testing.... read more
New non-invasive imaging method for showing oxygen in tissue
Learning how to look inside a body without having to cut it open is still an important part of medical research. One of the great challenges in imaging remains the visualization of oxygen in tissue.... read more
