The SPECT protocol consisted of 32 projections (180° using two opposing heads) of 10 s, each using a Symbia T2 hybrid scanner and low-energy high-resolution collimators (Siemens Healthcare, Erlangen, Germany).
The tomography systems used included a high-energy scanner and a low-energy scanner.
Directly before the PET acquisition, a transmission scan was performed with an ECAT-951 R scanner and a low-dose CT with the Biograph mCT for attenuation correction.
Furthermore, the results indicate that the proposed architectural design can prove to be a significant tool for SENSE reconstruction in modern MRI scanners and its low power consumption feature can be remarkable for portable MRI scanners.
Muscle oxygenation has been assessed in idealized situations of single-leg exercise based on the dMb signal (Richardson et al. 1995, 2001) but this was no option because of the difficulty of performing strong two-legged exercise in a MR scanner and recording the low SNR signal of dMb dynamically at the same time.
On the other side, the dynamic stress-CCT imaging, usually performed with scanner with high temporal resolution and low scan time, is obtained from multiple samples of myocardial attenuation at sequential time points after contrast injection with a method similarly to the stress-CMR previously described.
Thus, the goal of this study is seeking to successfully apply MRI for examining small rodents' spinal cord injury using a standard clinical 3 T scanner and to keep instrumental cost low.
Static stress-CCT imaging is usually preferred for scanner with low temporal resolution and long scan time in which the myocardial perfusion is reached from a single data sample acquired in arterial phase timing.
The results of measurements are in good agreements with wire scanners and slits at low duty-factor pulsed (LDFP) beam.
But conventional scanners have many shortcomings such as limited scanning frequency, high cost and low reliability.
Participants lay motionless on the scan table in light clothes and no metal containing objects, while a scanner emitting low energy X-rays passed over the body.
