Medical Imaging

Physicians utilize medical imaging to see inside the body to diagnose and treat patients. This includes computed tomography (CT), magnetic resonance imaging (MRI), X-ray, ultrasound, fluoroscopy, angiography,  and the nuclear imaging modalities of PET and SPECT. 

PET/CT in HD: Seeing More, Clearly

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.

Turning to SPECT/CT for Calcium Scoring to Diagnose Coronary Artery Disease

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. 

Pint-size Power: PET/CT and SPECT/CT in Pediatrics

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

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.

The Ammonia Option: PET/CT Myocardial Perfusion Imaging

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.

Look, No Hands: Reports Go Directly to Referrer EMRs

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

Molecular Imaging Training Gaining Traction

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.

Molecular Imagings Next Horizon: Whole-Body SPECT/CT

SPECT is far from the new kid on the molecular imaging block, but except for cardiac imaging, this nuclear medicine modality has not yet realized routine clinical utility as a replacement for conventional planar scanning. Recently developed reconstruction protocols and hybrid SPECT/CT scanners, however, could breathe new life into SPECT by opening the door to clinically feasible whole-body SPECT/CT. The University of Texas M.D. Anderson Cancer Center in Houston, is at the cutting edge of SPECT/CT research. This month, M.D. Anderson experts, Chair of Nuclear Medicine , Associate Professor , and Senior Medical Physicist Bill Erwin from the department of Imaging Physics discuss the clinical path to and potential of whole-body SPECT/CT.
