Two forms of radiographic images are in use in medical imaging. Projection radiography and fluoroscopy, with the latter being useful for catheter guidance. These 2D techniques are still in wide use despite the advance of 3D tomography due to the low cost, high resolution, and depending on the application, lower radiation dosages with 2D technique.
Diagnosis is made by comparing stress images to a further set of images obtained at rest which are normally acquired prior to the stress images. MPI has been demonstrated to have an overall accuracy of about 83% ( sensitivity : 85%; specificity : 72%) (in a review, not exclusively of SPECT MPI), [ 3 ] and is comparable with (or better than ...
