When asked what they liked most about NESTOR, students rated videos first, followed by (in decreasing order) interactive x-ray cases, online-layout and extent of the offered material, and finally availability of podcasts and tests.
For comparison with the x-ray case, we will calculate the required dose for electrons, making the same assumptions (which include large contrast between the chosen voxel and its surroundings).
However, this theory appeared much too complicated for a neophyte to apply it to the X-ray case.
For example, at the lower energies of the sulfur K-edge, the separation between elastic scatter and S Kα fluorescence is almost an order of magnitude smaller than with the hard X-ray case, being only about 160 eV, which is sufficiently small that the fluorescence and scatter cannot be adequately resolved by conventional solid-state dispersive detectors.
The study identified 136 cases with x ray requests from 79 GPs and 11 reporting radiologists.
We suggest an X ray of the abdomen in cases where external sources of lead exposure have been eliminated.
Morgan found that GPs' would x ray knees in 42% of cases to confirm or assess degenerative change whilst 40% had no clear diagnosis in mind [ 24].
Any retropulsed fragment was seen on postoperative X-ray (8 cases) .
Any retropulsed fragment was seen on postoperative X-ray (8 cases).
Among the remaining cases, the diagnosis was based on surgical reports in 99 cases, X-ray examinations in 60 cases, clinical examinations in 31 cases, autopsy in 4 cases and death certificates in 24 cases.
Fragmentation was successful in 80 (81.6%) patients as follows: combined ET/ESWL: 67 cases; SpyGlass EHL: 4 cases; X-ray guided EHL: 3 cases; and outpatient ESWL: 6 cases.
