Study Notes
MDCT Examination of the Chest
- The primary indication for a MDCT examination of the chest is to evaluate suspected or known thoracic disease, particularly in patients with symptoms such as chest pain, cough, or shortness of breath.
Patient Positioning
- The recommended patient position for a routine CT chest scan is supine, with the patient's arms elevated above their head to reduce artifacts and improve image quality.
Scout View AP Chest
- The purpose of the scout view AP Chest in a CT chest examination is to localize the thoracic region, identify any abnormalities, and plan the subsequent CT scan.
Window Settings
- The mediastinal window (WL 30-40, WW 300-400) is used to visualize soft tissue structures in the mediastinum during a CT chest examination.
Post-Contrast CT Examination
- The specific indication for performing a post-contrast CT examination of the chest is to assess vascular structures, such as pulmonary embolism, and to evaluate lesions or masses that may enhance with contrast material.
