The radiologist may recommend premedication with corticosteroids if contrast is required and a prior allergy is suspected. Follow the protocol recommended by your radiology department. 如果您是眼科医生,请扫描下面的二维码关注我们,我们会每天与您...
Clinical impact of allergy and pre-medication in CT studies with low-osmolality intravenous iodinated contrast mediaA. Talmon aY. Tal aJ. Moss aI. Hershkowitz aD. Shaham bJ. Sosna bA.Y. Hershko a
these diameters are derived from segmentations that are error-prone. In contrast, one can view the use of MPICT-based boundary conditions as a lumped-parameter correction
serum creatinine level greater than 1.5 mg/dL; allergy to iodinated contrast; pregnant state; body mass index greater than 35 (calculated as weight in kilograms divided by height in meters squared); evidence of active clinical instability or life-threatening disease; or inability to adhere to stud...
In case of allergy to contrast medium, antihistamines and corticosteroids will be taken before the CT scan and before the CTO-PCI. The immediate result of the CTO-PCI procedure will be evaluated during the first two days of hospitalisation after the procedure. As part of standard of care, ...
The increasing urine activity between the imaging time points in the presented study is a drawback of the implemented protocol which might have masked lesions close to the ureter or bladder. However, 96% of patients received a contrast-enhanced CT demarcating the urinary tract on late imaging. ...
Limitations to utilization of CCTA include patients with irregular heart rhythms, known high levels of coronary calcification (CAC scores > 400), borderline tachycardia (HR>80 despite pre-treatment), baseline renal impairment, and known IV contrast allergy. A number of controlled clinical trials and...
If the serum creatinine level was 2.0 mg/dL or greater for men or 1.8 mg/dL or greater for women (to convert to μmol/L, multiply by 88.4), or if some other contraindication (including contrast allergy or inability to reduce heart rate to <60/min) to performing CCTA was present, ...
Dual-energy CT technology allows simultaneous acquisition of data sets at 2 different photon spectra in a single CT acquisition. Thereby, differences in material composition—ie, soft tissue polyps and contrast tagging—can be detected by variations in photon absorption at different photon energies of...
