“…Incidental inflammatory uptake in joints from degenerative osteoarthritis is almost ubiquitously visualized. Acute processes such as herniated discs, discitis, osteomyelitis, and septic arthritis can also demonstrate focal FDG uptake and may be mistaken for osseous metastases [ 58 , 59 ]. Focal FDG uptake in the muscles can be related to tendinous insertion, myositis, or intramuscular infection and mistaken for sites of malignancy [ 60 – 62 ].…”

Purpose of review To review acute findings commonly encountered during routine clinical FDG PET/CT studies and present key imaging features to differentiate them from malignant counterparts. Recent findings FDG PET/CT is extensively used in routine clinical practice for oncology patients. Incidental acute findings in patients undergoing FDG PET/CT are increasingly common, and awareness of these findings and their mimics are important in delivering a clinically relevant and accurate radiological report for directing further management. Summary This article will review examples of common acute findings encountered during routine FDG PET/CT scans, compare them against examples of FDG-avid malignancy that can mimic these findings and emphasize key imaging findings to differentiate acute findings from their malignant mimics.

“…[ 18 F]FDG-PET/CT is important for diagnosing persistent musculoskeletal infections [ 45 ] including the detection of chronic osteomyelitis [ 46 ] ( Figure 4 ). Some other uses of [ 18 F]FDG-PET/CT may include evaluation of the diabetic foot [ 47 ], implant-related infections in the leg [ 48 ], and septic arthritis [ 44 , 49 , 50 , 51 , 52 ].…”

“…Few studies exist regarding the usefulness of [ 18 F]FDG-PET in septic arthritis. [ 18 F]FDG accumulates in inflammatory arthritis, and its diagnostic usefulness in septic arthritis is likely limited [ 44 , 49 , 50 , 51 , 52 ].…”

Is Imaging Bacteria with PET a Realistic Option or an Illusion?

The application of [18F]-fluorodeoxyglucose ([18F]FDG) as a radiotracer to detect sites of inflammation (either due to bacterial infection or primary inflammation) has led to exploring the role of PET in visualizing bacteria directly at sites of infection. However, the results from such efforts are controversial and inconclusive so far. We aimed to assess the limitations of PET as an effective modality in the diagnosis of bacterial infections. Inflammation due to bacterial infections can be visualized by using [18F]FDG-PET. However, the non-specificity of [18F]FDG makes it undesirable to visualize bacteria as the underlying cause of inflammation. Hence, more specific radiotracers that possibly bind to or accumulate in bacteria-specific receptors or enzymes are being explored. Several radiotracers, including 2-deoxy-2-[18F]fluorosorbitol ([18F]FDS), 6-[18F]-fluoromaltose, [11C]para-aminobenzoic acid ([11C]PABA), radiolabeled trimethoprim (11C-TMP) and its analog fluoropropyl-trimethoprim (18F-FPTMP), other radiolabeled sugars, and antimicrobial drugs have been used to image microorganisms. Unfortunately, no progress has been made in translating the results to routine human use; feasibility and other factors have constrained their success in clinical settings. In the current article, we discuss the limitations of direct bacterial visualization with PET tracers, but emphasize the important role of [18F]FDG-PET as the only option for detecting evidence of infection.
