Before the advent of tomographic imaging, it was postulated that decay of 90 Y to the 0 +
excited state of 90 Zr may result in emission of a positron–electron pair. While the branching …

Introduction Cardiac amyloidosis is a rare condition characterized by the deposition of well-structured
protein fibrils, proteoglycans, and serum proteins as amyloid. Recent work has …

Patients experience anxiety during imaging procedures because of the confined space,
uncertainty about the procedure, worry about the results, and other concerns. When a patient …

New developments in PET/CT technology have enabled the commercial availability of
continuous bed motion (CBM) acquisition methods. This technology has some potential …

Routine quality control is a critical aspect of properly maintaining high-performance small
animal imaging instrumentation. A robust quality control program helps produce more reliable …

Most dynamic imaging protocols require long scan times that are beyond the range of what
can be supported in a routine clinical environment and suffer from various difficulties related …

Respiratory motion during PET can cause inaccuracies in the quantification of radiotracer
uptake, which negatively affects PET-guided radiotherapy planning. Quantitative accuracy can …

Objectives: Positron emission tomography (PET) is affected by various kinds of patient
movement. Frame-by-frame image registration is one of the most practiced motion correction …

The Siemens Biograph Vision 600 is the latest generation of PET/CT from Siemens
Healthineers and the first to use silicon photomultipliers as the light-sensing mechanism in the …

Introduction Fluorine-18 labeled radiopharmaceuticals undergo quality control testing for
residual phase-transfer-catalyst content. The almost universally used quality-control test is a …
