High-definition is the goal in PET/CT imaging. HD met PET/CT last yearwhen Siemens Medical Solutions introduced a new technology designed tobring significant improvements to PET/CT image quality. High DefinitionPET (HD•PET) brings the promise of sharper and more clearly definedimages across the entire field of view, as well as the potential toprovide greater accuracy in lesion detection, especially small lesions,and thus improve cancer staging and more targeted treatment.

Michael Milbourne, MD, of New Life Cardiovascular in Wyndmoor, Pa., anuclear cardiologist in academic and private practice, is committed tooffering his patients outstanding, informed and proactive clinicalcare. In the last year, SPECT/CT has become an essential diagnostictool in Milbourne’s practice. 

PET/CTa technology whose potential is now being appreciated, but has yet to be fully realizedhas proven successful in the accurate staging and monitoring of oncology patient therapy for a variety of cancers. SPECT/CT, while relatively new, is beginning to make its mark in areas such as oncology, cardiology, neurology imaging. 

Diagnosing heart disease in women—the No. 1 cause of death of womenacross the globe—is sometimes difficult, but molecular PET and SPECTimaging is beginning to contribute to resolving this problem.

13N-ammonia, an established imaging probe for measuringmyocardial perfusion, has now been made available for use in thecommunity. This has thus far been difficult because of the shorthalf-life of 13N-ammonia of about 10 minutes. But even that time factor has been worked out.

As molecular imaging emerges from the cocoon of nuclear medicine, fueled by changes that have made it a vital technique for diagnosing disease and predicting and monitoring treatment response, training for physicians and technologists has made its way to the forefront for many education programs around the United States.

 A panel of seven clinical experts and public policy leaders offer insight on personalized medicine, technology, biomarkers and the DRA.

PET/CT has come a long way since Time magazine awarded the scanner one of its Medical Inventions of the Year award in December 2000. Published literature since 1996 has established strong evidence for the advantages of PET/CT over PET and CT alone for characterizing lesions as malignant or benign, and for staging, restaging and therapy monitoring of cancer. In addition, emerging applications include imaging of cardiovascular diseases and infection.
