Is brain SPECT
useful in degenerative dementia diagnosis?
Evaluating patients with suspected dementia including early detection, differential diagnosis, and in the predementia phase, known as mild cognitive impairment, SPECT
can detect functional deficits and thus guide prognosis.
Hence there is no direct proof that the larger EDV, higher LVEF and lower ESV from 16-frame gated SPECT
are indeed more accurate.
Flurpiridaz F 18 PET imaging shows superiority over SPECT
in an obese population and provides images with better quality, and less attenuation, which can lead to increased diagnostic certainty by physicians.
offers superior contrast resolution of conventional sestamibi dual-phase planar parathyroid scintigraphy.
The average results for the planar and SPECT
MUGA were computed (Table l).
/CT market is a bigger market than the PET, PET/CT and PET/MRI, because the instruments have been in longer use, are cheaper, and have become the common technique for a wide range of indications
1), showed a linear heterogeneous tracer activity seen in the mid abdomen; it was initially assumed to be physiological bowel uptake, but on the SPECT
CT imaging, the tracer activity co-register to the soft tissue opacities seen in the omentum on the CT images (Fig.
Results showed that after follow-up, patients' SPECT
scans revealed substantial decreases in radiotracer binding to the dopamine transport system in the nigrostriatal regions of the brain.
Characteristic patterns of functional involvement using SPECT
and PET can, however, enable more accurate differentiation of these forms of dementia (Fig.
machine is used for detecting many diseases, such as cancer, especially thyroid cancer, angina, heart muscle health, and internal bleeding, especially chronic internal bleeding.
The study was designed to build on the findings of Bloom and colleagues (1996) and Borghesani and colleagues (2010) who reported that SPECT
imaging added significant value in the diagnostic workup and clinical management of neurologically-involved patients.
