Science to Practice: Can Functional MR Imaging Be Useful in the Evaluation of Cardiorenal Syndrome?

abstract：:Digital radiographs obtained with a CT scanner were evaluated as an alternative to conventional pelvimetry. Dosimetry studies demonstrated an absorbed radiation dose of 22 mrad for each digital radiograph, approximately 3% of the dose for comparable standard radiographs. Distance measurements were accurately made on d...
