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.

In the study, patients who had recovered from an COVID infection were injected with a small amount of the 89Zr-labeled radiotracer before undergoing a uExplorer PET/CT scan.

Better risk stratification can improve clinical decision making and better outcomes, experts involved in the study explained in EJR.

PET/CT imaging in these patients increases overall survival depending on the cancer’s stage, with those diagnosed with stage 3A and 3B NSCLC appearing to benefit the most from the exam.

This week in AJR, experts shared how they were able to reduce FDG PET scan acquisition times by 33%, thus reducing the amount of total radiation exposure to more vulnerable pediatric patients. 

The American Medical Association (AMA) Board of Delegates approved a policy calling on payers to reimburse for the drug regadenoson and not to employ payment policies that push for cardiologists to change the drug they use for pharmacologic stress for one that is considered less safe. The policy was adopted at the AMA 2022 meeting. #AMA #AMA175 #AMAmtg #ASNC

Salvage radiation therapy guidelines for patients with prostate cancer recurrence need to be updated to include findings identified on PSMA PET, according to new research shared at SNMMI’s annual conference this week. 

“High-quality artificial intelligence-generated images preserve vital information from raw PET images without the additional radiation exposure from CT scans,” experts involved in the study explained.

For 45% to 47% of patients who were deemed negative after conventional baseline scans, the use of the radiohybrid imaging agent resulted in at least one true positive PET finding

The study, which followed 195 patients recently diagnosed with multiple myeloma (MM), found that a negative PET/CT scan six months after diagnosis and induction therapy was significantly linked with improved survival.

The new equipment, which initially will be used to treat prostate and neuroendocrine tumors, is expected to be operational in July.

The findings could help clinicians manage patients’ treatment when the origin of axillary lymphadenopathy is of concern, experts suggested.

The therapeutic combination of 177Lu-PSMA-617 with idronoxil (NOX66) reduced PSA levels in 86% of study participants.

There is not agreement among the top structural heart experts if CT is required for left atrial appendage occlusion (LAAO), but a Henry Ford Hospital study shows it can improve outcomes.

Ron Blankstein, MD, Brigham and Women's Hospital, explains recent advances in coronary computed tomography angiography (CCTA) technology. 

With the elevation of cardiac CT to a 1A indication in the 2021 Chest Pain Guidelines, there has been a large amount of interest in starting coronary artery CT angiography (CCTA) programs.
