CTA Head, CTP, MRI Brain, and Non-contrast CT Head imaging use was determined from Common Procedural Terminology (CPT) codes. ICD10 Codes I60-I69 were used to indicate cerebrovascular disease. Statistical comparisons used 95% CI for rate per 100,000 ED visits.#Results:ED utilization of ...
For patients with suspected or known coronary artery disease (CAD) without percutaneous coronary intervention (PCI), researchers found that those with a normal CTA-derived quantitative flow ratio (CT-QFR) had a 22 percent higher MACE-free survival rate. Photon-Counting CTA for Patients with PAD:...
performed, with more than 400 patterns of testing. Magnetic resonance imaging of the brain or spine was ordered in 23.2 % of patients, whereas a glucose tolerance test was rarely obtained (1.0 %). Mean Medicare expenditures were significantly higher in the diagnostic period than in the baseline ...
Scans were acquired 60 min later from the skull vertex or base of the brain to the upper thighs. 4.1.2. RATHL In the RATHL trial from NCRI, the Lymphoma Study Association (LYSA) and the Italian Foundation for Lymphoma (FIL), 1214 patients with newly diagnosed advanced classic HL ...
By using a low-energy VMI (between 40 and 55 keV), it is possible to achieve a significant increase in iodine attenuation, resulting in better image quality, even with a large decrease in the volume of injected iodinated contrast media, ultimately reducing nephrotoxicity (especially in cancer ...
Based on the assumption that the TBR contrast of 18F-FDOPA uptake in brain tumor is similar to that of 18F-FET [20,21], other authors successfully adopted the same approach in patients with gliomas investigated by 18F-FDOPA PET/CT [18,19]. In our patients, GTVTBR assessed in a ...
