Volume of herniation (mm3) was calculated by measuring the area (mm2) in each axial image
and multiplying this value by the scan thickness (4 mm) plus the inter-slice gap (1 mm).13 The patients were assigned into three groups based on change in extruded hernia disc volume as follow:
In the axial image
of the source angiogram (C) and in the coronal view of the time-of-flight image (D), the arrows identify the vessel to better advantage than in A and B.
First, the maximum CT number (in HU) of the hyperdense paraspinal vein finding on the 0.75 mm axial image
best demonstrating the finding was determined based on ROI analysis by one of the readers.

. (d) T2-weighted axial image
Caption: Figure 3: CT axial image
shows a large cyst in the right lower lobe representing parenchymal hydatid cyst (yellow arrow); there is also a large cyst with air seen in the left lower lobe representing hydatid cyst in the left lung (green arrow).
The T12 vertebral body appears to be rotated counterclockwise on axial image
and displaced posteriorly into the bony spinal canal, resulting in severe spinal canal stenosis.
Postoperative computed tomography: (c) axial image
, (d) sagittal image, and (e) 3-dimensional image.
(a) A 25 MHz UBM image clearly shows a slightly subluxated lens, the anterior and posterior capsular tear of the lens (arrows), and the opacity of whole lens; (b) an axial image
of 50 MHz UBM shows only the tear and opacity of the anterior lens capsule (arrow); other lens lesions were not shown clearly, especially in the posterior capsule of the lens; and the tear location could not be seen; (c-f) the longitudinal section images of 50 MHz UBM show only the tear and opacity of the anterior lens capsule (arrow), and the differences in the distance between the lens equator and the ciliary process in these figures were not significantly different.
