Navigating the intricate world of data analytics, one method has emerged as a key tool in confronting missing data: multiple imputation. Its strength is further fortified by its powerful variant, robust imputation, which enhances precision and reliability results. In challenging landscape analysis, non-robust methods can be swayed few extreme outliers, leading to skewed imputations biased estim...

BACKGROUND AND PURPOSE Diffusion-weighted imaging (DWI) and apparent diffusion coefficient (ADC) maps provide information at MR imaging that may reflect cell attenuation and integrity. We hypothesized that cerebellar tumors in children can be differentiated by their ADC values. METHODS Brain MR imaging studies that included ADC maps were retrospectively reviewed in 32 patients with histologic...

The standard approach to changing people’s energy consumption, which involves information about appropriately structured economic incentives, is becoming increasingly questioned. In an experiment, we investigated if it is possible to affect the electricity consumption recommended for the average American citizen by priming participants with either pro-social aspects of the “American stereotype”...

BACKGROUND AND PURPOSE MR image-guided gamma knife radiosurgery is often used to treat intra-axial metastatic neoplasms. Following treatment, it is often difficult to determine whether a progressively enhancing lesion is due to metastatic tumor recurrence or radiation necrosis. The purpose of our study was to determine whether relative cerebral blood volume (rCBV), relative peak height (rPH), a...

OBJECTIVE To evaluate the role of diffusion weighted imaging in differentiating the cause of ring enhancing brain lesions. STUDY DESIGN Analytical, descriptive study. PLACE AND DURATION OF STUDY Department of Radiology, The Aga Khan University Hospital, Karachi, from March 2007 to July 2011. METHODOLOGY Diffusion weighted imaging (DWI) was performed on 37 patients having ring enhancing le...

BACKGROUND AND PURPOSE Diffusion-weighted MR imaging and the trace apparent diffusion coefficient (ADC) provide important structural information about tissues. The purpose of this study was to investigate the relationship between trace ADC values and the enhancement pattern of multiple sclerosis (MS) lesions. METHODS Ninety-six lesions, identified in 24 patients with MS, were characterized by...

OBJECTIVE Adherence with bisphosphonates therapy is generally low. Enhancing adherence with bisphosphonates would be effective in achieving the full benefits of therapy albeit a growth in the expenditure for supporting incremented drug use is expected. The cost-effectiveness of enhancing adherence with oral bisphosphonates in a large population of osteoporotic women has been assessed in the cur...
