PET/CT

Positron emission tomography/computed tomography is a hybrid nuclear medicine imaging technique that helps radiologists spot abnormal metabolic activity. PET/CT is commonly used to diagnose cancers, heart diseases and certain brain disorders, among other conditions.

Advanced imaging does not always improve outcomes, data suggest

Although advanced imaging exams have proven benefits in defining disease severity, new data indicate that more sophisticated studies might not impact outcomes as much as previously thought. 

New practice guidelines for PET imaging of neuroendocrine tumors

Issued by the Society of Nuclear Medicine and Molecular Imaging (SNMMI) and the European Association of Nuclear Medicine (EANM), the new guidelines are intended to inform any practitioners involved in ordering, performing, reading and reporting SSTR PET imaging.

Amyloid plaque patterns on PET imaging predict Alzheimer's progression in asymptomatic patients

Experts involved in the new research suggest that identifying these spatiotemporal variations could play an important role in clinical research and precision medicine.

E-cigarettes cause worse inflammation than tobacco cigarettes, new PET data shows

The use of e-cigarettes has increased significantly in recent years, mostly due to the fact that many consumers believe them to be a safer option than traditional cigarettes.

New radiotracer could change how radiologists understand inflammation

Labeled as LW223, the fluorinated PET radiotracer is the first of its kind to be impervious to rs6971 polymorphism—a genetic mutation that inhibits the diagnostic view of inflammation imaging.

A 'clear lack of adherence' in imaging guidelines is impacting lung cancer survival rates

A study published in the January issue of the Journal of Nuclear Medicine reveals that nearly half of Medicare patients with NSCLC in the United States do not complete recommended FDG PET/CT scans prior to treatment.

‘Revolutionary’ new CT scans identify the most common cause of high blood pressure

Primary aldosteronism (PA) is one the single most common causes of hypertension, but identifying patients with PA—and knowing which ones may benefit from a surgical treatment—can be quite challenging.

New type of PET/CT scan could change how hypertension is diagnosed and treated

The 10-minute scan can “light up” aldosterone-producing nodules in the adrenal glands following an injection of metomidate—a radioactive dye that binds specifically to aldosterone-producing nodules.

Positron, a New York-based nuclear imaging company, will now provide Upbeat Cardiology Solutions with advanced PET/CT systems and services. 

The nuclear imaging isotope shortage of molybdenum-99 may be over now that the sidelined reactor is restarting. ASNC's president says PET and new SPECT technologies helped cardiac imaging labs better weather the storm.

CMS has more than doubled the CCTA payment rate from $175 to $357.13. The move, expected to have a significant impact on the utilization of cardiac CT, received immediate praise from imaging specialists.
