Non-invasive quantification of absolute myocardial blood flow (MBF) and myocardial flow reserve (MFR) provides incremental benefit to relative myocardial perfusion imaging (MPI) to diagnose and manage heart disease. MBF can be measured with single-ph

Introduction: Myocardial blood flow (MBF) imaging with SPECT is possible using cardiac-specific cameras. Single-center studies have shown that SPECT MBF is accurate compared with PET MBF and angiography. Clinical implementation requires consistency o

Dedicated cardiac SPECT cameras which employ multi-pinhole detectors have variable photon sensitivity within the camera’s field-of-view such that a lower number of photon counts is typically detected from the base of the heart than from the apex. C

In addition to acquired photon counts, image noise depends on the image reconstruction algorithm. This work develops patient-specific activity or acquisition time protocols to standardize the average noise in a reconstructed image for different patie

Despite excellent sensitivity, small target sizes combined with low resolution can lead to weak signals in nuclear medicine imaging. When the signal in a lesion is of the same order of magnitude as the background signal in the blood, it can be diffic

Purpose New single photon emission computed tomography (SPECT) cameras using fixed pinhole collimation are increasingly popular. Pinhole collimators are known to have variable sensitivity with distance and angle from the pinhole aperture. It follows

The originally published version of this article contained typographical errors in the units of photon sensitivity. The units of counts · MBq-1 · min-1 and kcounts · mCi-1 · min-1 were mistakenly recorded as counts · MBq · min and kcounts · mC

Small animal and clinical SPECT cameras based on multi-pinhole detector arrangements typically boast spatial resolutions of 1–2mm and 4mm respectively. However, directional variability of the local imaging capability within the field-of-view (FOV)
