Trial Outcomes & Findings for Hyperpolarized Noble Gas MR Imaging for Pulmonary Disorders (NCT NCT00846573)

NCT ID: NCT00846573

Last Updated: 2012-11-15

Results Overview

We have applied hyperpolarized 3He MR imaging to a range of subject with various disorders. We have developed our scanning techniques so as to acquire optimized images for each disorder.

Participant Flow

Recruitment began November 2008 and enrollment started January 2009. Recruitment continued until the study was terminated, April 2011. Participants were asthmatics, COPD patients, or CF patients as confirmed by their physician. Recruitment was completed from the UMass Memorial Medical Centre. Alternatively, healthy volunteers were also recruited.

Participants were excluded if their diagnosis of a lung condition could not be confirmed by medical records.

Measure
COPD
This population is made up of only confirmed COPD patients. Diagnosis must be confirmed through their doctor prior to enrollment. Participants will inhale Hyperpolarized Helium-3: Participants will be required to breath in individual 1 liter bags of gas while in an MRI to produce lung images. These bags of gas are each made up of 333mL of Helium-3 gas and 667mL of Nitrogen. Three bags will be administered to acquire three different scans.
Asthma
This population is made up of only confirmed asthmatics. Participants will inhale Hyperpolarized Helium-3: Participants will be required to breath in individual 1 liter bags of gas while in an MRI to produce lung images. These bags of gas are each made up of 333mL of Helium-3 gas and 667mL of Nitrogen. Three bags will be administered to acquire three different scans.
Cystic Fibrosis
This population is made up entirely of confirmed cystic fibrosis patients. Diagnosis must be confirmed through their physician. Participants will inhale Hyperpolarized Helium-3: Participants will be required to breath in individual 1 liter bags of gas while in an MRI to produce lung images. These bags of gas are each made up of 333mL of Helium-3 gas and 667mL of Nitrogen. Three bags will be administered to acquire three different scans.
Healthy
This population is made up of subjects who are considered clinically healthy. This means that there are no records of any chronic disorders or pulmonary history. Participants will inhale Hyperpolarized Helium-3: Participants will be required to breath in individual 1 liter bags of gas while in an MRI to produce lung images. These bags of gas are each made up of 333mL of Helium-3 gas and 667mL of Nitrogen. Three bags will be administered to acquire three different scans.

PRIMARY outcome

Timeframe: 15 second breath-hold

Population: We recruited participants of each category until we were satisfied with the images we obtained.

We have applied hyperpolarized 3He MR imaging to a range of subject with various disorders. We have developed our scanning techniques so as to acquire optimized images for each disorder.
