High-dose contrast-enhanced MRI in multiple sclerosis

Neuroradiology, 1996
Contrast-enhanced MRI is effective for assessing disease activity in multiple sclerosis (MS) and may provide an outcome measure for testing the efficacy of treatment in clinical trials. To compare the sensitivity of high-dose gadolinium-HP-DO3A with that of a standard dose of gadolinium-DTPA, we studied 16 patients with relapsing-remitting MS in the ...

125I brachytherapy k-edge dose enhancement with AgTPPS4

Medical Physics, 1998
Photon activation is a radiotherapy technique in which an element is added to the absorbing medium to raise the probability that a photoelectric interaction will occur, thus causing an increase in the absorption of ionizing radiation. Binding energies of key elements within an absorbing medium are closely matched with the incident photon energies to ...

Ultra-low dose naltrexone enhances cannabinoid-induced antinociception

Behavioural Pharmacology, 2005
Both opioids and cannabinoids have inhibitory effects at micromolar doses, which are mediated by activated receptors coupling to Gi/o-proteins. Surprisingly, the analgesic effects of opioids are enhanced by ultra-low doses (nanomolar to picomolar) of the opioid antagonist, naltrexone.

Enhancement of methotrexate absorption by subdivision of dose

Cancer Chemotherapy and Pharmacology, 1979
A comparison was made in fasting patients between a single 100 mg oral dose of methotrexate formulated as its sodium salt in a palatable syrup and the same total quantity of drug administered in four divided doses of 25 mg taken at 2-h intervals. Allocation to the order of these treatment schedules was on a random basis.

Low-Dose Ritonavir for Protease Inhibitor Pharmacokinetic Enhancement

Annals of Pharmacotherapy, 2002
OBJECTIVE: To examine the use of low-dose ritonavir as a pharmacokinetic enhancer for HIV protease inhibitors. DATA SOURCES: Primary articles, review articles, and conference abstracts identified by MEDLINE search (1995–May 2001) and secondary sources.

X-Ray Dose Enhancement, II.

1978
Abstract : A discussion of x-ray dose enhancement at material interfaces is presented including definition, problem identification and worst-case estimation, prediction techniques, and analysis of dose enhancement characteristics. Empirical, analytical, and Monte Carlo prediction techniques are discussed.

Low-Dose Contrast-Enhanced MR Angiography

2011
Today, three-dimensional contrast-enhanced magnetic resonance angiography (CE-MRA) is a widely accepted and powerful diagnostic tool for assessment of almost all vascular territories. Its noninvasive nature and flexibility make CE-MRA an appealing alternative to digital subtraction angiography (DSA) or computed tomography angiography (CTA). In addition,

The Case for High-Dose Motivational Enhancement Therapy

Substance Use & Misuse, 2004
Motivational Enhancement Therapy (MET) is a brief therapy for treating substance use-related problems that draws upon the stages of the change model of Prochaska et al. (1992) and the clinical techniques of Motivational Interviewing (MI) Miller et al. (1992).

Radiation dose enhancement associated with contemporary dental materials

The Journal of Prosthetic Dentistry, 2019
Electron backscatter radiation from dental materials can contribute to soft tissue injury in patients undergoing head and neck radiation therapy.The dose enhancement from the materials used for prosthodontic restoration of the dentition has not been well quantified.

Enhanced bremsstrahlung spectrum reconstruction from depth–dose gradients

Physics in Medicine and Biology, 2005
We present a technique to significantly improve the accuracy of bremsstrahlung spectra reconstructed from central-axis depth-dose data using inverse methods. While typical approaches directly use the measured depth-dose data, we show the advantage of using the gradient of these data for reconstruction. The inverse problem in terms of gradients is shown
