PET-CT

PET-CT combines positron emission tomography (PET) detectors and computed tomography (CT) into one imaging system. 

Positron emission tomography (PET) using a 68Ga-labeled fibroblast activation protein inhibitor (FAPI) can noninvasively identify and monitor pulmonary fibrosis, according to research presented at the Society of Nuclear Medicine and Molecular Imaging 2021 Annual Meeting.

A) Axial CT images through the mouse lungs at 7 and 14 days after intratracheal administration of bleomycin or saline (as a control), demonstrating increased lung fibrosis in the bleomycin group (white arrows). (B) CT attenuation histograms in Hounsfield units (HU) after lung segmentation demonstrate increased attenuation in the lungs in the bleomycin group than the control group (p <0.05), consistent with increasing fibrosis (n=3). (C) Representative axial PET/CT fusion images at 20 and 60 min demonstrating increased FAPI uptake in the lungs of the bleomycin group (white arrows) with no significant uptake in the control group (yellow arrows). (D) Time-activity curve of lung uptake ROI analysis demonstrating higher FAPI uptake in the lungs of the bleomycin group than the control (p < 0.05), 14 days after bleomycin (n=3). (E) Ex vivo biodistribution data of lung tissue demonstrating higher radiotracer uptake in the lungs of the bleomycin group than the control (n=3). *p<0.05, **p<0.01.

According to an open-access article in ARRS’ American Journal of Roentgenology (AJR), increased axillary lymph node or ipsilateral deltoid uptake is occasionally observed on FDG or 11C-choline PET performed after Pfizer-BioNTech or Moderna COVID-19 vaccination

(A) 57-year-old woman with right upper arm melanoma who received the first dose of the COVID-19 vaccine (Pfizer-BioNTech) in the left deltoid 15 days prior to FDG PET/CT. FDG uptake is observed within left axillary lymph nodes (arrow, SUVmax = 9.3).

(B) 62-year-old man with metastatic prostate carcinoma who received the second dose of COVID-19 vaccine (Pfizer-BioNTech) in the right deltoid 7 days prior to 11C-choline PET/CT. 11C-choline uptake is observed within right axillary lymph nodes (arrows, SUVmax = 3.1) as well as the right deltoid muscle (circle, SUVmax = 1.7).

Indeterminate lesion on PET/CT classified by PET/MRI for 53-y-old man with lung cancer.

Indeterminate lesion on PET/CT classified by PET/MRI for 53-y-old man with lung cancer. Contrast-enhanced CT (A), PET (B), and fused 18F-FDG PET/CT (C) images are displayed in comparison with contrast-enhanced T1-weighted MRI (D), PET, and fused 18F-FDG PET/MRI (F) images. In CT (A), hyperdense, subcentimeter liver lesion (arrows) in segment VII is suggestive of transient hepatic attenuation difference or small hemangioma. As malignancy cannot be excluded, it needs further investigation. On PET/MRI, lesion is clearly classified as metastasis because of contrast enhancement and tracer uptake due to later acquisition time point. Follow-up CT confirmed diagnosis after 78 d.

Total-body dynamic 18F-FDG PET imaging with the uEXPLORER scanner allows us to monitor the spatiotemporal distribution of glucose concentration in metastatic tumors in the entire body (a). As compared to a typical clinical standardized uptake value image (b), the parametric image of FDG influx rate (Ki) can achieve higher lesion-to-background (e.g., the liver) contrast. In addition to glucose metabolism imaging by Ki, total-body dynamic PET also enables multiparametric characterization of tumors and organs
