Warmth and swelling were assessed on physical examination; orthogonal radiographs
of the affected ankle were reviewed at the 2-month follow-up, which showed catastrophic fixation failure, osteopenia, periarticular fragmentation, and dislocation of the ankle joint (Figures 1a & 1b).
usually are required to properly describe a fracture.
The seed is deposited in or adjacent to the targeted lesion through the needle, and position is confirmed on 2 view orthogonal radiographs
. At the time of excision, the surgeon localizes the seed with a gamma probe, similar to the procedure for localizing a sentinel lymph node.

The scores based on the orthogonal radiographs and the photographs of the segmented roots (42 cases) were compared and differences for parameters 2 and 4, respectively were tested using Wilcoxon signed-rank test, whereas the percentage agreement between the scores was calculated for parameter 1.
A comparison between the orthogonal and mesio-angulated radiographs for question one showed agreement in 78% of the cases; the score was higher for the orthogonal radiographs in 10% of the cases, whereas a higher score was seen for the eccentric radiographs in 12% of the cases.
However, what may appear as adequate on CT images to a radiologist may not be acceptable because fiducial tracking is obtained using orthogonal radiographs
, from which digitally reconstructed radiographs are made.2 This may result in overlapping markers which will not be usable.
The positions of these guide-wires were checked on orthogonal radiographs (Fig.
All of the surface replacement heads were within 20% of their intended experimental positions as determined by orthogonal radiograph measurements (Table 2).
revealed microhepatica and possible ventricular distension as well as a multilobular soft tissue opacity in the area of the gonads and kidneys (Fig 1).
Two standard orthogonal radiographs
were taken of all samples by using a Kodak Directview Classic CR System (Carestream, Rochester, NY, USA) with a consistent film focus distance of 100 cm and an exposure of 50 kVp and 3.2 mA.
