A dual-head gamma camera (Siemens) that was adjusted to 140 keV and had a 10% width (range, 133-147 keV) was used for all planar imaging
. Approximately 1 hour after the 99 mTc-MIBI administration, the neck and the upper thorax of the patients were examined with a SPECT/CT (SIEMENS INTEVO 6 xSPECT) equipped with a dual-head gamma camera (matrix size, 128X128), which was combined with the CT system positioned on the same gantry.
Imaging Protocol: In all studies, after applying 20-25 mCi Tc99m MIBI, at 15 min and 2 h, planar imaging
was made, and after a complete MIBI washout, 5 mCi Tc99m pertechnetate were given and thyroid scintigraphy was performed.
Posttherapeutic 131I SPECT-CT offers high diagnostic accuracy when the findings on conventional planar imaging
are inconclusive and allows a tailored patient treatment regimen.
Whole body and joint-specific static planar imaging
in healthy control subjects, as expected, did not reveal joint-specific localization.
Further imaging modalities are usually required to explain the unexpected I-131 uptake, but it is difficult to guide further examinations due to the absence of anatomical location data on planar imaging
SPECT Planar Imaging
. Imaging studies were performed in the tumor-bearing mice using SPECT (Symbia T6, Siemens, Erlangen, Germany) with a 3.0 mm pinhole collimator.
This guide introduces the basics of magnetic resonance imaging, covering its physics from basic principles to more advanced topics, such as MR angiography and fast scanning techniques, and techniques made possible with high-performance gradients, such as echo planar imaging
. It contains an introductory math chapter and discussion of the process of image creation, including the concepts of gradients, signal/image processing, and k-space, and artifacts.

On SPECT/CT images, the focus of increased radioiodine uptake in the mediastinum seen on planar imaging
was localized to the 2.0 x 1.7 cm right paratracheal mediastinal mass visualized on CTA (Figure 3).
Using relative measurement, fiducial value was set to 3.5 Mpa, Hertz model was defined as cell model [16,17], AFM planar imaging
Our study population was made up of the first 24 patients at our facility who had undergone SPECT/CT parathyroid imaging with technetium-99m ([sup.99m]Tc) MIBI and a group of 24 patients who had undergone MIBI planar imaging
