PET/CT and contrast-enhanced CT have been considered the standard imaging modalities in the diagnosis of upper abdominal malignancies. PET/CT can be challenging in soft tissue delineation, especially in the upper abdomen. The recent development of PET/MRI for clinical use has shown promising results, with MRI providing superior soft tissue contrast and PET providing biochemical and metabolic information. Combined PET/MRI may allow simultaneous benefit in the assessment of patients in a single session, improving patient journey, lesion detectability, diagnostic performance, and prognostic information. PET/MRI also provides the ability for tissue characterization and reduces radiation exposure. The most powerful driver is PET, and the newer PET radiopharmaceuticals with the addition of dynamic contrast-enhanced MRI, diffusion-weighted imaging, and MR spectroscopy may increase the sensitivity and specificity of disease recognition and have clinical effect. In this article, we review the advantages and limitations of PET/MRI in upper abdominal malignancies.
This research output has an Altmetric Attention Score of 1. 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 02 March 2016.
All research outputs
#23,750,856
of 26,436,676 outputs
Outputs from Seminars in Nuclear Medicine
#616
of 720 outputs
Outputs of similar age
#238,484
of 278,095 outputs
Outputs of similar age from Seminars in Nuclear Medicine
#6
of 6 outputs
Altmetric has tracked 26,436,676 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 720 research outputs from this source. They receive a mean Attention Score of 3.2. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
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 278,095 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 6 others from the same source and published within six weeks on either side of this one.
