PET/CT and SPECT/CT are helping to detect and diagnose coronary artery disease in women earlier and better. Previously under-diagnosed or misdiagnosed altogether particularly in women, new exams are effectively assessing myocardial perfusion, offering an alternative to nuclear stress tests that often lead to false positive results in women. Fewer attenuation artifacts also mean sharper images.

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.

John Griffith, CIO of Epic Imaging, Portland, Ore, says, “They asked us for it, and we had to come up with a solution.” The radiology practice provides imaging for close to 2,000 physician referrers; what they wanted was electronically delivered radiology reports sent to their practices not via fax, nor even over the Web, where they had to reside

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.
