Detection of the Arterial Input Function Using DSC-MRI Data
It addresses the need for reproducible and reliable arterial input function detection in medical imaging, but is incremental as it only reviews existing methods.
This paper reviews existing semi- and fully automatic methods for detecting the arterial input function in DSC-MRI data, which is crucial for accurate perfusion quantification, but does not present new experimental results or concrete numbers.
Accurate detection of arterial input function is a crucial step in obtaining perfusion hemodynamic parameters using dynamic susceptibility contrast-enhanced magnetic resonance imaging. It is required as input for perfusion quantification and has a great impact on the result of the deconvolution operation. To improve the reproducibility and reliability of arterial input function detection, several semi- or fully automatic methods have been proposed. This study provides an overview of the current state of the field of arterial input function detection. Methods most commonly used for semi- and fully automatic arterial input function detection are reviewed, and their advantages and disadvantages are listed.
