background health literacy presents an enormous challenge in the delivery of effective healthcare and quality outcomes. we evaluated the impact of low health literacy (lhl) on healthcare utilization and healthcare expenditure.   methods database analysis used medical expenditure panel survey (meps) from 2005-2008 which provides nationally representative estimates of healthcare utilization and e...

We aim to compare radiological with histological tumour thickness (RTT with HTT) for oral squamous cell carcinoma (OSCC), and the ability of both to predict cervical metastasis. The MRI images and histopathology reports of 102 consecutive OSCC cases were compared and the relationship between RTT and HTT, calculated as a "shrinkage factor" by the gradient of the best fitting regression line. Mos...

Angular momentum in protostellar discs can be transported either radially, through turbulence induced by the magnetorotational instability (MRI), or vertically, through the torque exerted by a large-scale magnetic field. We present a model of steady-state discs where these two mechanisms operate at the same radius and derive approximate criteria for their occurrence in an ambipolar diffusion do...

A common problem in clinical MRI is anatomic misalignment of imaging slices across successive examinations. This unnecessarily complicates the radiologic assessment of anatomic change over time on serial MRI studies. To address this problem, spherical navigator echoes, which can detect rigid body motion in all six degrees of freedom, were used to guide spatial location and orientation adjustmen...

Introduction: Perianal region is a commonly affected area in the course of several inflammatory, infectious, and neoplastic diseases. Several imaging modalities are used evaluation this magnetic resonance (MRI) emerges as modality choice due to its superb soft tissue resolution. MRI not only useful for initial detection perianal pathologies but also follow-up these disorders. Magnetic (MRI), wi...

Abstract Background Inappropriate prescriptions can lead to adverse consequences for patients. It also imposes excessive cost on the patients, payers and health systems. The current study aimed at estimating rate of inappropriate brain Magnetic Resonance Imaging (MRI) their financial burden in Iran. Methods Using systematic stratified sampling method, this cross-sectional recruited 385 particip...

A case of cervical (C) spinal intramedullary metastasis and multiple small brain metastases from papillary thyroid carcinoma was presented. Spinal metastasis caused posterior neck and left shoulder pain, dysesthesia in both legs, and motor weakness in both legs and left arm, though the brain metastases were asymptomatic. Both the spinal and brain metastases were successfully treated by frameles...
