Fusion Imaging: Cardiac Applications of SPECT/CT and PET/CT

Medical diagnoses commonly rely on assessment of a patient’s functional status and physical condition, and there are superb imaging modalities capable of providing that information within certain parameters. Radionuclide-tracer techniques such as positron-emission tomography (PET) and single-photon emission computed tomography (SPECT) provide functional information, but have relatively poor spatial resolution and can lack the anatomical information needed to localize or stage disease.

Cardiac MRI: Questions and Answers

The first MRI images of the heart were produced more than 20 years ago. Since that time, cardiac MRI techniques have progressively improved. With these impressive advances in spatial and temporal resolution and increased imaging speed, cardiac MRI has become one of the most valuable diagnostic tools for heart disease, especially over the past 5 years. Because of the advantages of cardiac MRI over other techniques used in heart-disease assessment, cardiac MRI is beginning to be used routinely at specialized centers.

Introduction

An explosion in non-invasive imaging of the heart will lead to significant changes in practice patterns in coming years and the need to forge new cooperative relationships.

Introduction

MR angiography (MRA) has matured into an extremely reliable, accurate, and valuable diagnostic vascular tool. Accurate imaging of excellent quality, using MRA for both cardiac and noncardiac applications, is now available in many medical centers
