In this work, the quantitative aspect of myocardial imaging is of main concern. The following quality control measurements have been assessed: planar and SPECT resolution and sensitivity, stability and response during rotation, mechanical alignment and rotational linearity, SPECT Author: Nasser Salim.

Background. Single photon-emission computed tomography (SPECT) is widely used for the assessment of hibernating myocardium (HM). The aim of this study was to test the hypothesis that myocardial contrast echocardiography (MCE), because of its better spatial and temporal resolution, would be superior to SPECT Cited by:.
Although semi-quantitative CMR perfusion has been evaluated in the setting of CAD, semi-quantitative techniques underestimate perfusion at high flow rates and have a potential diagnostic disadvantage compared with fully quantitative perfusion which increases linearly over a wide range of flow rates.
However, fully quantitative studies in humans with CAD have been limited and lack adequate comparisons to semi-quantitative and qualitative analyses Cited by: 2.Quantitative software for myocardial perfusion single photon emission computed tomography (SPECT) has advanced significantly over the last 25 years.
