Nuclear imaging (also known as nuclear scintigraphy or scanning) is an established modality in medical imaging that provides diagnostic information that cannot be obtained by other techniques such as x-rays, computed tomography, magnetic resonance and ultrasound. Nuclear imaging requires the administration of a short-lived radionuclide tracers which emit gamma rays. These tracers have no side effects and are not toxic however patients may be required stay at the imaging centre for 24 hours to allow for radionuclide decay.
A nuclear scanner is used to detect the gamma rays creating detail of both the structure and physiological function of the underlying anatomy being studied. Each type of procedure uses a tracer which is specific to the organ or tissue of interest such as bones for equine fractures or the thyroid for feline hyperthyroidism. Nuclear imaging is recognised as one of the most sensitive tests available to detect disease at an earlier stage than possible with conventional radiology imaging alone by providing complimentary information on the function of organs rather than how they look.
The data collected from the scanner is processed by fully accredited technologists and scientists on powerful computer systems to generate both visual assessment of a patients body and quantitative analysis of abnormalities. A variety of different phases can be acquired such as dynamic studies of blood flow or urinary clearance, static images of tissues and 3D images of the heart or spine and results are interpreted by specialist veterinary radiologists.
TeleMedVET is the only provider of equine 3D-SPECT which results in better image quality than two-dimensional or planar imaging because focal sources of activity are not superimposed on one another. As a result, the contrast between the target and the background (the signal-to-noise ratio) is greatly increased. In addition, the volume imaging capacity of SPECT permits reconstruction at any angle—including the transaxial, coronal, and sagittal planes. All of which can greatly enhance the ability to localise sites of injury in the pelvis of the horse.
Our scanners are coupled with the state-of-the-art GE healthcare Xeleris post-processing software providing precise motion correction tools and expanded reconstruction applications. Image clarity is enhanced with HiRes collimators which improve spatial resolution and results are easily accessible on mobile devices via our cloud based telemedicine system (sepStream).
Affiliated with leading veterinarian specialists we pride ourselves on our innovative approach to imaging with a focus on quality, continous improvement and advanced diagnostics.
