Assessment of liver graft function and regeneration by galactosyl-human serum albumin (99mTc-GSA) liver scintigraphy in adult living-donor liver transplantation.

14 Dec 2009 BACKGROUND: In adult living-donor liver transplantation (LDLT), the assessment of the graft functional reserve is very important. We evaluated the graft functional reserve by technetium-99m-diethylenetriaminepenta-acetic acid-galactosyl-human serum ... Read more...

Clinical outcome after 450 revascularization procedures for moyamoya disease. Clinical article.

30 Oct 2009 OBJECT: Moyamoya disease (MMD) is a rare cerebrovascular disease mainly described in the Asian literature. To address a lack of data on clinical characteristics and long-term outcomes in the treatment of MMD in North America, the authors analyzed ... Read more...

Technical information about 'Tomography, Emission-Computed, Single-Photon'

Definition: A method of computed tomography that uses radionuclides which emit a single photon of a given energy. The camera is rotated 180 or 360 degrees around the patient to capture images at multiple positions along the arc. The computer is then used to reconstruct the transaxial, sagittal, and coronal images from the 3-dimensional distribution of radionuclides in the organ. The advantages of SPECT are that it can be used to observe biochemical and physiological processes as well as size and volume of the organ. The disadvantage is that, unlike positron-emission tomography where the positron-electron annihilation results in the emission of 2 photons at 180 degrees from each other, SPECT requires physical collimation to line up the photons, which results in the loss of many available photons and hence degrades the image.
