Absolute Myocardial Blood Flow via Single-Time-Point Imaging in PET and SPECT: Cross-Validation Against Dynamic 13N-Ammonia PET.

BACKGROUND Quantitative assessment of myocardial blood flow (MBF) and flow reserve (MFR) is clinically superior to relative imaging but limited by dynamic scanning requirements. We evaluated a novel single-time-point (STP) method to estimate MBF from a single static image using a population-based power law model of the...

Automated patient-derived noise power spectrum estimation in abdominal CT: a preliminary validation

Background. Established methods are available for measuring the noise power spectrum (NPS) in computed tomography (CT) by using uniform phantoms. However, in clinical practice, direct estimation of this metric from patient images is desirable for continuous image quality monitoring and protocol optimization. Methodolog...
