While not included in this meta-analysis, recently published data from the nationwide Danish registry demonstrated that evaluation of stable chest pain with CCTA was associated with greater use of statins and aspirin, likely explaining the observed reduction in non-fatal MI in this cohort. CCTA was...
All patients had undergone chest X-ray during annual medical examinations. In addition, all patients except one (patient 10) underwent CT scans more than 5 times during the previous 5 years, and 3 ML patients underwent a positron emission tomogra- phy (PET) examination before this study. ...
Our goal was to see what proportion of all thoracic CTs are done without plus with contrast in the Medicare population. METHOD AND MATERIALS The Medicare Part B Physician/Supplier Procedure Summary Master Files for 2001, 2006, and 2011 were our data source. CPT codes 71250 (CT thorax without...
In lung EIT an array of electrodes is attached around the patient's chest. The electrodes are used to inject small alternating currents into the body and simultaneously measure the resulting voltages between pairs of electrodes. Usually the electrodes are attached equidistantly in a plane around ...
2.2. CT Acquisition All chest CT examinations were performed using a 128-slice MDCT scanner (Somatom Definition Flash; Siemens, Germany) with the following parameters: collimation, 128 × 0.6 mm; beam pitch, 1.2; tube voltage, 120 kVp; and tube current-time product, 110 mAs with automatic ...
2.1.2. Private Dataset We retrospectively reviewed the medical records and contrast-enhanced chest CT scans of patients with solitary pulmonary nodules (SPN) that were followed up at Gangneung Asan Hospital (GNAH), Kangwon National University Hospital (KNUH), and Hallym Sacred Heart Hospital (HSHH...
(3) 2.3. Patient Data Preparation In vivo respiratory-correlated planning 4DCTs of the entire chest of six lung cancer patients were acquired at the department of radiotherapy. The 4DCTs were acquired using a Siemens Sensation Open CT scanner (Siemens AG, Erlangen, Germany) at 120 kVp, 80 ...
contrast-enhanced oncologic chest-CT of a first-generation Germany photon-counting CT and a second-generation dual-source dual-energy CT using comparable exam protocol settings 100 China To investigate whether DECT, a novel quantitative technique, can be used for quantitative severity assessment in ...
One such tool is icolung (icometrix), which performs an AI-based chest CT analysis for the detection and prognosis of COVID-19 infection from chest CT scans. The software quan- tifies clinically relevant parameters from a non-contrast CT scan, which are summarized in a structured report, ...
