Updated 08/16/25 CT Chest Full High-Res Reviewed 05/14/25 Indications - interstitial lung disease (ILD), pulmonary fibrosis, interstitial pulmonary fibrosis (IPF), usual interstitial pneumonitis (UIP), nonspecific interstitial pneumonitis (NSIP), bronchiectasis, asbestosis, sarcoidosis, hypersensitivity pneumonitis, connective tissue disease, rheumatoid, scleroderma and pneumoconiosis. Only use this full HRCT protocol if ordered as full HRCT or protocoled by rad. Use CT chest HRCT charges. Do not use regular CT chest charges. GENERAL SCAN NOTES Move the patient's arms over his/her head if possible. Remove any metal from the imaging field of view. Have the patient cough a few times to clear secretions. This reduces incidence of small lung nodules. Topogram - lung apices through diaphragm (obtained during end inspiration). Craniocaudal scan coverage: Supine end inspiration phase - lung apices through adrenal glands (obtained during end inspiration). Supine end expiration phase - lung apices through diaphragm (obtained during end inspiration). Prone end inspiration phase - carina through diaphragm (obtained during end inspiration). Adjust FOV (field of view) on topogram to smallest without cropping anatomy. Scan parameters for the supine end inspiratory phase are the same as routine chest protocol. Scan parameters for the supine end expiratory and prone end inspiratory phases are the same as low-dose chest protocol. IV Contrast: 100 mL Omnipaque-300, inject at 2 mL/sec, 30 secs scan delay. For GE scanners, it is essential for the 1st recon thickness on the scanner to match the 1st recon thickness in this protocol book for the prescribed Noise Index to be valid. The 1st recon should generally be the thickest recon in the protocol.
