VIDEO: 2 key advances in cardiac nuclear imaging technology
Randall Thompson, MD, immediate past president of the American Society of Nuclear Cardiology (ASNC), explains two key advances in cardiac nuclear imaging. These include the use of hybrid SPECT-CT and PET-CT systems to add anatomical information and calcium scoring, and the use of coronary flow reserve imaging to add additional information to exams.
Over the past few years at the annual ASNC meetings, the addition of PET quantitative myocardial perfusion (QMP) flow reserve to PET exams has been a hot topic. It can enhance cardiac PET imaging helping show the severity of the ischemia detected on a PET scan. This information can help determine the what therapy is used to treat the patient. QMP can determine if revascularization will help a patient.
CT is used to enhance nuclear imaging by offering attention correction to produce clearer images. It also offers anatomical imaging, including the ability to perform a calcium scoring scan at the same time. This enables an Agatston score to be generated, showing the patient's risk of a cardiovascular event over the next 10 years.
