Outcome of tunneled hemodialysis catheters placed via the right internal jugular vein by interventional radiologists.

abstract：:MRI is firmly established as an essential modality in the imaging of the temporal bone and lateral skull base. It is used to evaluate normal anatomic structures, evaluate for vestibular schwannomas, assess for inflammatory and/or infectious processes, and detect residual and/or recurrent cholesteatoma. It is also exte...

abstract：:In the redistribution of cells through the division cycle between dose fractions, the sensitizing effect is greatest when small doses per fraction are used. Since nonproliferating tissues limit the dose in radiotherapy and will not be sensitized by redistribution, the more the dose is fractionated and the lower the do...
