The criteria for an RIS diagnosis are as follows: [5] [4] [6] The presence of incidental MRI findings in the CNS white matter: Ovoid and well-circumscribed homogeneous foci, with or without involvement of the corpus callosum; T2 hyperintensities larger than 3 mm in diameter, which fulfill at least 3 of the 4 Barkhof MRI criteria [7] for DIS
Medical billing practices vary across states and healthcare settings, influenced by federal regulations, state laws, and payor-specific requirements. Despite these variations, the fundamental goal remains consistent: to streamline the financial transactions between physicians and payors, ensuring access to care and financial sustainability for ...
The key purpose of bulk billing is to provide an economic constraint on medical fees and charges. To address the decline in bulk billing, the Australian Medical Association (AMA) called on the federal government to revise indexation to ensure rebates better reflect the rising costs of providing medical care and running a practice, which it says ...
Utilization management is "a set of techniques used by or on behalf of purchasers of health care benefits to manage health care costs by influencing patient care decision-making through case-by-case assessments of the appropriateness of care prior to its provision," as defined by the Institute of Medicine [1] Committee on Utilization Management by Third Parties (1989; IOM is now the National ...
A clinical coder—also known as clinical coding officer, diagnostic coder, medical coder, or nosologist—is a health information professional whose main duties are to analyse clinical statements and assign standardized codes using a classification system.
Conventional phase contrast imaging can be extended by applying flow-sensitive gradients in 3 orthogonal planes within a 3D volume throughout the cardiac cycle. Such 4D imaging encodes the velocity of flowing blood at each voxel in the volume enabling fluid dynamics to be visualised using specialist software. Applications are in complex ...
A variant of diffusion weighted imaging, diffusion spectrum imaging (DSI), [4] was used in deriving the Connectome data sets; DSI is a variant of diffusion-weighted imaging that is sensitive to intra-voxel heterogeneities in diffusion directions caused by crossing fiber tracts and thus allows more accurate mapping of axonal trajectories than ...
All patients are reviewed for contraindications prior to MRI scanning. Medical devices and implants are categorized as MR Safe, MR Conditional or MR Unsafe: [6] MR-Safe – The device or implant is completely non-magnetic, non-electrically conductive, and non-RF reactive, eliminating all of the primary potential threats during an MRI procedure.
