Positron Emission Tomography Computed Tomography

PHILADELPHIA — In this Healio Video Perspective, Suzanne E. Schindler, MD, PhD, revealed phosphorylated tau biomarker assays were most accurate in identifying amyloid positron emission tomography status in Alzheimer’s disease.

C2N Diagnostics released the PrecivityAD2 blood test, which uses positron emission tomography scans and cerebrospinal fluid tests to assist in accurate diagnosis for those presenting with signs or symptoms of Alzheimer’s disease.

A proxy for prostate-specific membrane antigen PET/CT upstaging was strongly predictive of meaningful, long-term cancer-specific outcomes, according to results of a multinational cohort study published in JAMA Network Open.

The FDA today approved Gallium 68 PSMA-11 as the first drug for PET imaging of prostate-specific membrane antigen-positive lesions in men with prostate cancer, according a press release from the agency.

The addition of PET molecular imaging to conventional imaging helped guide treatment decisions that led to improved DFS among men with recurrent prostate cancer, according to study results presented at the virtual ASTRO Annual Meeting.

Blacks and Hispanics appeared less likely than non-Hispanic whites to receive guideline-recommended PET/CT imaging at the time of lung cancer diagnosis, according to results of a study published in Journal of the National Cancer Institute.

A novel molecular imaging technique demonstrated higher diagnostic accuracy than conventional imaging among a cohort of men with high-risk prostate cancer, according to results of a randomized phase 3 study published in The Lancet.

De-escalation of treatment after two cycles of chemotherapy and a negative PET scan appeared safe and feasible among a cohort of men with low-volume metastatic seminoma, according to results of a phase 2 trial presented at Genitourinary Cancers Symposium.

A 75-year-old woman with a medical history significant for obesity, diabetes mellitus type 2 and coronary artery disease presented with a 6-month history of constitutional symptoms, multiple hospitalizations for dehydration and electrolyte imbalances, and a precipitous functional decline. She was noted on several occasions to have a marked leukocytosis and was treated with various antibiotic regimens without a known infectious source. A CT scan of the chest/abdomen/pelvis revealed what was thought to be an enlarged inguinal lymph node (Figure 1).
