Objective: Myocardial viability studies were assessed for repositioning accuracy as
adequate or inadequate by evaluation of NH3/FDG image correspondence and detection of …

Methods: The study was performed using 3 patients including one NH3 perfusion and two
18Ffluorodeoxyglucose viability examinations acquired on the Biograph TP 64 PET/CT …

2604 Objectives Misalignment of the CT and PET studies can be caused by respiratory or
cardiac motion and gross physical movement of the patient. In 13N-ammonia myocardial …

1723 Objectives: Heart-beating and respiration can cause emission-transmission
misregistration during attenuation correction in cardiac PET imaging, and this may lead to …

The purpose of this study was to investigate the accuracy of cardiac PET with post-injection
transmission scans. Methods We performed a phantom study using 18 F solution as well as …

The heart is a moving organ, depending on heart rate, situated in the chest that is moving
due to respiratory motion. The lungs during the heavier breathing (larger tidal volume) …

374 Introduction: Misregistration artifacts in cardiovascular PET imaging are one of the
greatest sources on misdiagnosis. However, most misregistration correction (MRC) …

1724 Objectives: In cardiac PET-CT protocols, a low dose CT is used for attenuation
correction of PET. Misregistration due to respiratory or patient motion between the …

Aim: Motion-induced PET-CT misalignment artifacts are common in myocardial blood flow
(MBF) measurements with 82Rb and 13N-ammonia. For 15O-water, MBF is based on the …
