The objective of this study was to quantify the effects of radiation-induced cancer risks in patients with Bosniak category IIF lesions undergoing CT versus MRI surveillance.AJR: American Journal of Roentgenology : Including Diagnostic Radiology, Radiation...
There are no known health risks associated with having an MRI scan.How much?A CT scan A CT scan produces around 7 mSv, or around the same amount of radiation as you'd expect to absorb if you spent a year in Cornwall, where the sun exposure and radioactive rocks pump up the levels ...

In our analysis, the proportion of PET/CTs conducted in the planning position is currently low, despite existing data and recommendations supporting enhanced alignment and reduced radiation exposure through the combination of PET and planning CT [32, 33]. One factor contributing to the limited use ...
Magnetic Resonance Imaging (MRI) is becoming increasingly important in radiation oncology. (earlier post: The increasing need and interest in MRI in radiation therapy). To be MR safe, patient positioning and immobilization devices cannot contain materials that are electrically conductive or magnetic. Or...

The MRI-only treatment process is currently an active field of research since it could eliminate systematic MR-CT co-registration errors [13,14,15], reduce medical cost, avoid diagnostic radiation exposure, and simplify clinical workflow. However, most MR bores are smaller than those of CT, res...

Ultrasound and MRI do not use ionizing radiation and thus were not included. Because CT and nuclear medicine examinations contribute such a large proportion of the radiation exposure from imaging, we newly abstracted additional patient-level data to allow accurate estimation of dose. For CT, we ...
