Hyperpolarized 3He and 129Xe MR Imaging in Healthy Volunteers and Patients with Chronic Obstructive Pulmonary Disease
To quantitatively compare hyperpolarized helium 3 (3He) and xenon 129 (129Xe) magnetic resonance (MR) images obtained within 5 minutes in healthy volunteers and patients with chronic obstructive pulmonary disease (COPD) and to evaluate the correlations between 3He and 129Xe MR imaging measurements a...

| description | To quantitatively compare hyperpolarized helium 3 (3He) and xenon 129 (129Xe) magnetic resonance (MR) images obtained within 5 minutes in healthy volunteers and patients with chronic obstructive pulmonary disease (COPD) and to evaluate the correlations between 3He and 129Xe MR imaging measurements and those from spirometry and plethysmography.
This study was approved by an ethics board and compliant with HIPAA. Written informed consent was obtained from all subjects. Eight healthy volunteers and 10 patients with COPD underwent MR imaging, spirometry, and plethysmography. Ventilation defect percentages (VDPs) at 3He and 129Xe imaging were obtained by using semiautomated segmentation. Apparent diffusion coefficients (ADCs) were calculated from 3He (b=1.6 sec/cm2) and 129Xe (b=12 sec/cm2) diffusion-weighted images. VDPs at hyperpolarized 3He and 129Xe imaging were compared with a two-tailed Wilcoxon signed rank test and analysis of variance; Pearson correlation coefficients were used to evaluate the relationships among measurements.
129Xe VDP was significantly greater than 3He VDP for patients with COPD (P |

This study was approved by an ethics board and compliant with HIPAA. Written informed consent was obtained from all subjects. Eight healthy volunteers and 10 patients with COPD underwent MR imaging, spirometry, and plethysmography. Ventilation defect percentages (VDPs) at 3He and 129Xe imaging were obtained by using semiautomated segmentation. Apparent diffusion coefficients (ADCs) were calculated from 3He (b=1.6 sec/cm2) and 129Xe (b=12 sec/cm2) diffusion-weighted images. VDPs at hyperpolarized 3He and 129Xe imaging were compared with a two-tailed Wilcoxon signed rank test and analysis of variance; Pearson correlation coefficients were used to evaluate the relationships among measurements.
129Xe VDP was significantly greater than 3He VDP for patients with COPD (P<.0001) but not for healthy volunteers (P=.35), although 3He and 129Xe VDPs showed a significant correlation for all subjects (r=0.91, P<.0001). The forced expiratory volume in 1 second (FEV1) showed a similar and significant correlation with 3He VDP (r=-0.84, P<.0001) and 129Xe VDP (r=-0.89, P<.0001), although the correlation between the FEV1/forced vital capacity (FVC) ratio and 129Xe VDP (r=-0.95, P<.0001) was significantly greater (P=.01) than that for FEV1/FVC and 3He VDP (r=-0.84, P<.0001). A significant correlation was also observed for 3He and 129Xe ADC (r=0.97, P<.0001); 129Xe ADC was significantly correlated with diffusing capacity of lung for carbon monoxide (r=-0.79, P=.03) and computed tomographic emphysema measurements (areas with attenuation values in the 15th percentile: r=-0.91, P=.0003; relative areas with attenuation values of less than -950 HU: r=0.87, P=.001).
In patients with COPD, the VDP obtained with hyperpolarized 29Xe MR imaging was significantly greater than that with 3He MR imaging, suggesting incomplete or delayed filling of lung regions that may be related to the different properties of 129Xe gas and physiologic and/or anatomic abnormalities in COPD.]]></description><identifier>ISSN: 0033-8419</identifier><identifier>EISSN: 1527-1315</identifier><identifier>DOI: 10.1148/radiol.12120485</identifier><identifier>PMID: 22952383</identifier><identifier>CODEN: RADLAX</identifier><language>eng</language><publisher>Oak Brook, IL: Radiological Society of North America</publisher><subject>Administration, Inhalation ; Aerosols - administration & dosage ; Aged ; Biological and medical sciences ; Chronic obstructive pulmonary disease, asthma ; Contrast Media ; Female ; Helium - administration & dosage ; Humans ; Investigative techniques, diagnostic techniques (general aspects) ; Isotopes ; Magnetic Resonance Imaging - methods ; Male ; Medical sciences ; Pneumology ; Pulmonary Disease, Chronic Obstructive - diagnosis ; Reproducibility of Results ; Sensitivity and Specificity ; Static Electricity ; Xenon Isotopes - administration & dosage</subject><ispartof>Radiology, 2012-11, Vol.265 (2), p.600-610</ispartof><rights>2015 INIST-CNRS</rights><rights>RSNA, 2012</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>314,776,780,27901,27902</link.rule.ids><backlink>$$Uhttp://pascal-francis.inist.fr/vibad/index.php?action=getRecordDetail&idt=26451385$$DView record in Pascal Francis$$Hfree_for_read</backlink><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/22952383$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>KIRBY, Miranda</creatorcontrib><creatorcontrib>SVENNINGSEN, Sarah</creatorcontrib><creatorcontrib>PARRAGA, Grace</creatorcontrib><creatorcontrib>OWRANGI, Amir</creatorcontrib><creatorcontrib>WHEATLEY, Andrew</creatorcontrib><creatorcontrib>FARAG, Adam</creatorcontrib><creatorcontrib>OURIADOV, Alexei</creatorcontrib><creatorcontrib>SANTYR, Giles E</creatorcontrib><creatorcontrib>ETEMAD-REZAI, Roya</creatorcontrib><creatorcontrib>COXSON, Harvey O</creatorcontrib><creatorcontrib>MCCORMACK, David G</creatorcontrib><title>Hyperpolarized 3He and 129Xe MR Imaging in Healthy Volunteers and Patients with Chronic Obstructive Pulmonary Disease</title><title>Radiology</title><addtitle>Radiology</addtitle><description><![CDATA[To quantitatively compare hyperpolarized helium 3 (3He) and xenon 129 (129Xe) magnetic resonance (MR) images obtained within 5 minutes in healthy volunteers and patients with chronic obstructive pulmonary disease (COPD) and to evaluate the correlations between 3He and 129Xe MR imaging measurements and those from spirometry and plethysmography.
