Investing in Hybrid Imaging Technology
Choosing a hybrid system is like buying a new car. In both cases, customers ask: Does it improve something for me? Is its technology mature? Is it cost-effective? Is it easy to operate? Is it more fun to drive? Does it make me more attractive? This article discusses investments in clinical hybrid imaging technology in general and PET-MR...

The Hyperimage Project
The EU-funded HYPERImage research project aims to merge the concurrent PET and MR imaging techniques, with the goal of opening new fields in therapy planning, guidance and response monitoring. PET/CT scanners allow functional information such as glucose uptake rates derived from an FDG-PET scan to be co-registered with anatomical features in the CT...

Applications of Molecular Imaging
Single-photon emission tomography (SPET) and positron emission tomography (PET) can be used to visualise molecular alterations in the living subject, allowing alterations in metabolic pathways to be seen, and facilitating early diagnosis and treatment of disease. FDG-PET has already been accepted as an essential tool in the staging and re-staging of...

Multimodality Imaging for Pre-Therapeutic Molecular Radiotherapy Dosimetry
The treatment of cancer with radiopharmaceuticals is expanding rapidly, in terms of both the numbers of patients treated and the range of treatments offered (Carlsson et al. 2003). An increasing number of radiopharmaceuticals are now being introduced to the clinic and there is a strong potential for this modality to play a larger role in cancer management...

Safe Use of MRI Contract Agents
Much attention has recently been focused on the safe use of gadolinium-based contrast agents (GBCAs) in MRI with regards to nephrogenic systemic fibrosis (NSF). In the wake of its discovery and subsequent investigation, many guidelines were created on the subject. Part one of this article reviews what guidelines are, what GBCAs are, and how GBCAs are...

Assessing the "Cost Versus Benefit" of Radiology
All nations aspire to obtaining the best value for money for their population, achieving the maximum heath gain for the money spent. Although a predominantly State-funded system like the NHS in the UK can look at these issues more readily than those with a mixed economy of healthcare, private insurers are also interested in value for money and are...

Radiology in Canada
Please Share with Us the Highlights of Your Career in Radiology. As a first year medical student I participated in a B.Sc. in medicine research project using ultrasound to compare the pulsations of the third ventricle in the brain intracranial pressure. When a local neurosurgery resident introduced a clinical ultrasound service I worked as an on-call...

Clinical Decision Support System
Medical imaging is a critical component of the care that health professionals provide. However, mounting evidence demonstrates that between 10 - 20% of imaging studies are unnecessary. Any clinical intervention without clear purpose or patient benefit creates waste and negatively affects quality of care. Rising costs alone for imaging are a looming...
