SPECT Technology Enables Comprehensive Cardiac Evaluation

Posted on 28 Jan 2009

New features to a single photon emission computed tomography (SPECT) system enables a comprehensive cardiac evaluation including perfusion, attenuation correction, and calcium scoring in just five minutes.

Originally introduced at the 2008 Society of Nuclear Medicine annual meeting on June 14-18, 2008, in New Orleans (LA, USA), the IQ•SPECT is Siemens Healthcare's (Erlangen, Germany) newest Symbia feature. IQ•SPECT technology is achieved with Smartzoom collimators that magnify the heart while imaging the rest of the torso under traditional conditions. Combining this cardio-centric orbit acquisition technique with fast, three-dimensional (3D) iterative reconstruction enables more confident diagnoses and improved patient comfort, enhancing image quality, speed, productivity, and throughput.

IQ•SPECT is U.S. Food and Drug- (FDA)-510k-cleared and commercially available on all Symbia S and T systems, and is field-upgradeable for any existing system.

$Image: Kyushu University researchers use Dynamic Chest Radiography (DCR) to evaluate the severity of Pulmonary Regurgitation (PR), a common complication after treatment of the congenital heart disease Tetralogy of Fallot. The analysis only requires the patient to hold their breath for seven seconds for a sequence of images of their heart to be taken. The images are then analyzed and extracted into a waveform that can show the severity of PR. The new technique\\\'s detection accuracy of severe PR is 93%, with a sensitivity of 93% and a specificity of 94%. (Photo courtesty of Kyushu University/Yuzo Yamasaki)$
