Relationships between patient characteristics and contrast agent dose for successful computed tomography venography with a body weight tailored contrast protocol

PMCID: 5902285
PMID: 29620634
DOI: 10.1097/MD.0000000000010231

[…] of the lbw and bsa on the validity of the contrast agent volume on ctv and ctpa protocols., we hypothesised that the bw-tailored protocol would be suitable to keep the contrast agent volume to yield varid venous enhancement on ctv images. the purpose of this study was to evaluate the relationship between the required contrast agent dose to acquire diagnostic-quality ctv with a bw-tailored […]

Detecting serum and urine metabolic profile changes of CCl4 liver fibrosis in rats at 12 weeks based on gas chromatography mass spectrometry

PMCID: 5525970
PMID: 28810615
DOI: 10.3892/etm.2017.4668

[…] shanghai, china) for providing help with data analysis., 519 peaks of the gc/ms spectra of the model and control groups were screened, corresponding to the number of the substance in serum when the varid was imported into the software, vip values >1.0 were selected as changed metabolites. from this, 7 metabolites from serum were demonstrated to be significantly altered., p<0.01, p<0.05 […]


Mechanism of Xinfeng Capsule on Adjuvant Induced Arthritis via Analysis of Urinary Metabolomic Profiles

PMCID: 4775768
PMID: 26989506
