NCT ID: NCT03612804 Completed - Lung Diseases Clinical Trials

Promoting Smoking Cessation in Lung Cancer Screening Through Proactive Treatment

PROACT
Start date: May 10, 2019
Phase: N/A
Study type: Interventional

This pragmatic trial will evaluate the value of routinely providing proactive smoking cessation support to current smokers as a part of participating in lung cancer screening within Veterans Health Administration.

NCT ID: NCT03570528 Completed - Intubation Clinical Trials

CT Analysis of the Anatomy of the Nasotracheal Intubation Pathway of Patients With Indication of Maxillary Advancement

Start date: May 20, 2018
Phase:
Study type: Observational

Differences in nasotracheal intubation pathway anatomy will be observed between healthy patients and patients with maxillary retrusion. The results will clarify the nasotracheal intubation tube preference for these patients.

NCT ID: NCT00088361 Completed - Healthy Clinical Trials

Effect of Respiratory Motion on Positron Emission Tomography Imaging

Start date: July 2004
Phase: N/A
Study type: Observational

This study will determine how breathing motions may affect positron emission tomography (PET) scans. It has been discovered that the quality of PET scans varies according to which part of the breathing cycle patients hold their breath. NIH Clinical Center patients 12 years of age and older who are scheduled to have PET and computed tomography (CT) scans as part of their standard medical care may be eligible for this study. Participants have their scheduled PET or CT scan as they normally would and are asked to hold their breath after breathing out, as is usual. In addition, for this study, patients are also asked hold their breath after breathing in and again at a point between breathing in and out. Each breath-hold is for around 15 seconds. The scans for each of the three different breath-holds are examined for differences. Some patients may also be asked to breathe through a tube called a pneumotachometer, or spirometer, to determine their normal breathing pattern. This involves breathing through a mouthpiece similar to a snorkel mouthpiece and takes about 2 minutes.
