Metastatic disease was excluded by chest X-ray, bone scan in the case of bone pain, ultrasonography of the upper abdomen in the case of abnormal liver biochemistry and, in the majority of the patients (100 pts)., by a CT scan of the pelvis.
A variant of area scanning (in this case, using the author's web page (Step 4) to identify related publications) updates the physical equivalent suggested by Bates [ 16].
In the case of the normal group, the number of RBDEs was significantly lower with the optimal scan distance setting only for the entire scan, while in the case of the DME group the same trend was observed both for the entire scan and the peripheral scan parts.
In order to ensure measurements in the same suspected lymph nodes, sonographically examined lymph nodes were marked on diagnostic CT scans or in the case of lymph node conglomerates, the extension of the scanned node was marked on skin.
The improvement in quality was partly due to improved spatial resolution, but was largely due to the averaging of multiple images within a scan (50 in the case of figure 1C) made possible by a substantially faster scan rate.
The motivation for using 3D scan data in the case of planning is primarily to have up-to-date and verified spatial data, including any undocumenter alterations from drawings and models.
Changes of volume status can be readily inferred from variations in diameter of the inferior vena cava (IVC) with a bedside, non-invasive, repeatable point of care ultrasound scan, especially in the case of hypovolemia resulting from hemorrhage or other causes of acute intravascular depletion [1 3].
Also, for the synchronous rotation in particular, an underestimation of the velocity is possible if there is a slight delay between the rotation of the prism and the circular scan, in that case Δβ cannot be approximated as being zero.
We acknowledge that it would had been very valuable to have an objective pre and post-chemotherapy evaluation of the response by a CT scan, RMI, and/or PET scan in all the cases, however, only nine cases had CT scan pre and post therapy.
