Test Bolus was calculated by an initial contrast injection of 20mls and time to peak taken when 100 HU (Hounsfield Units) was reached (Figure 1). Vascular enhancement, Signal to Noise Ratio (SNR), Contrast to Noise Ratio (CNR), image noise, radiation dosimetry, contrast use were recorded. ...
This relationship constitutes evidence that the magnitude of the psychotropic activity of 5-HT1A receptor ligands is a positive function of their intrinsic activity at the receptor, and suggests that F 13714, which had maximal effects in the forced swimming test significantly larger than any of the...
This prospective, single-institution study was approved by the Institutional Review Board, and written informed consent was provided by each patient. From December 2015 to June 2019, 317 consecutive patients received tri-phase abdominal CTA. Patients with iodine contrast media allergy, known renal dysf...
Assays of drug penetration in tissues and activity against intracellular bacilli add modestly to the predictive value of in vitro measures of drug activity but still do not predict sterilizing activity. In contrast, animal models of tuberculosis have predicted relative drug potency (including sterilizing...
The relationship between the iodine load and tumor conspicuity was also analyzed. The mean CT number of the pancreas (HUpancreas) was higher in the 0.5gI/kg group (158.8HU) than in the 0.4 (121.7HU) and 0.3 (106.6HU) gI/kg groups (P<0.05). Tumor-to-pancreas contrast (HUtumor-to-...
In contrast, animal models of tuberculosis have predicted relative drug potency (including sterilizing activity), the efficacy of multidrug regimens, and the duration of therapy needed. Despite pharmacokinetic parameters that would suggest the need for multiple doses per day, all of the first-line ...
