Abstract

Our aim was to assess the diagnostic potential of (18)F-FDG PET using partial volume correction and dual-time-point imaging in the assessment of solitary pulmonary nodules. We included 265 patients in this retrospective study (171 men; 94 women; age range, 41-92 years). All had pulmonary nodules on CT, and diagnosis was confirmed by biopsy or follow-up CT. All underwent whole body FDG PET, 60 min after FDG injection. Of the 265 patients, 255 underwent second FDG PET for chest 100 min after injection. Maximum SUVs for nodules were calculated from both scans. Partial volume correction for first time SUVs was applied, using coefficient factor. Malignancy was defined using the following criteria: (1) Visual assessment; (2) First time SUV > or = 2.5; (3) Partial volume corrected first time SUV > or = 2.5; (4) second time SUV > or = 2.5; (5) Increase in SUV over time; (6) Increase or no change in SUV; (7) First time SUV > or = 2.5 and/or increase or no change in SUV. Biopsy and follow-up revealed 72 malignant lung nodules and 193 benign nodules. Sensitivity, specificity and accuracy for the five criteria were as follows: (1) 97, 58 and 68%; (2) 65, 92 and 85%; (3) 84, 91 and 89%; (4) 90, 80 and 83%; (5) 84, 95 and 92%; (6) 92, 92, and 92%; (7) 95, 90 and 91%, respectively. Dual-time-point (18)F-FDG PET has potential impact on improving the diagnostic accuracy for malignant lung nodules. Dual-time-point (18)F-FDG PET imaging should be included in the clinical work-up of patients with pulmonary nodule.

Attention Score in Context

This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 10 January 2012.
All research outputs
#1,907,146
of 7,792,430 outputs
Outputs from European Journal of Nuclear Medicine & Molecular Imaging
#125
of 991 outputs
Outputs of similar age
#29,408
of 99,765 outputs
Outputs of similar age from European Journal of Nuclear Medicine & Molecular Imaging
#3
of 10 outputs
Altmetric has tracked 7,792,430 research outputs across all sources so far. This one has received more attention than most of these and is in the 61st percentile.
So far Altmetric has tracked 991 research outputs from this source. They receive a mean Attention Score of 2.1. This one has gotten more attention than average, scoring higher than 68% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 99,765 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 69% of its contemporaries.
We're also able to compare this research output to 10 others from the same source and published within six weeks on either side of this one. This one has scored higher than 7 of them.
