AIM: To evaluate the clinical utility of hepatic clearance (HC) measured with technetium-99m-diethylenetriaminepenta-acetic acid-galactosyl human serum albumin (Tc-GSA) single-photon emission computed tomography (SPECT) to estimate the degree of liver
[TOP] Dopamine transporter imaging with single photon emission computed tomography (DAT-SPECT) is investigational for all indications, including but not limited to: Aiding in the diagnosis of patients with clinically uncertain parkinsonian syndromes; OR Distinguishing between parkinsonian syndromes and essential tremor; OR Distinguishing between dementia with Lewy bodies and Alzheimer dis...

We propose a new method for reconstruction of images in single photon emission computed tomography (SPECT), when the activity distribution of the object is time-varying. The activity evolution is modeled with the first-order Markov model, and linear observation model is used to characterize the measurement system. The state-space representation of the measurement sequence reduces to an ill-cond...
The X-Ray CT scanner and MRI imaging of the brain have changed the study of this organ, in health and in disease. To add to the detailed demonstration of anatomy, functional imaging of the human brain is now carried out by either positron emission computed tomography (PET) or by single photon emission computed tomography (SPET). PET allows for the investigation of brain blood flow, metabolism a...
