Abstract Background Diagnosis of aortic graft infection is challenging, and delayed diagnosis is associated with poor prognosis. Positron emission tomography/computed tomography (PET/CT) has improved diagnostic accuracy. Case summary A patient with a history of congenital heart disease was admitted due to fever. He had a history of four cardiac surgeries, including the Bentall procedure for endocarditis. Blood cultures were negative. A semi-mobile mass was detected in the distal portion of the aortic tube graft in echocardiography. PET/CT scan was used to confirm tube graft infection and to support proceeding to cardiac surgery. Discussion Using multimodality imaging, including PET/CT scan in combination with echocardiography, can improve diagnostic accuracy for the detection of aortic tube graft infection, infection of prosthetic valves, or intra-cardiac devices, especially in high-risk surgical cases.

Objective: To determine the diagnostic accuracy of 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) for detecting metastasis and its impact on patient management with upper tract urothelial carcinoma (UTUC). Patients and Methods: Consecutive patients with UTUC underwent 18F-FDG PET/CT after CT for initial staging (n = 47) and for restaging at recurrence (n = 9). Diagnostic accuracy for detecting metastases with PET/CT and CT was compared statistically. The impact of PET/CT on patient management was assessed by comparing questionnaires that were completed by the attending physicians before and after PET/CT. Results: In the lesion-based analysis, 142 lesions were diagnosed as metastases. The sensitivity of PET/CT was significantly better than that of CT (85 vs. 50%, p = 0.0001). In the patient-based analysis, 22 patients were diagnosed as having metastases. The sensitivity/specificity/accuracy of PET/CT tended to be superior to those of CT, but these values were not significantly different (95, 91, and 93% vs. 82, 85, and 84%; p = 0.25, 0.50, and 0.063, respectively). The clinicians changed their assessments of disease extent and management plans in 18 (32%) and 11 (20%) patients, respectively, based on the PET/CT results. Conclusions: The diagnostic accuracy of PET/CT for detecting metastasis was superior to that of CT. PET/CT provided additional information to the CT-based staging, which had an impact on patient management.

Positron emission tomography/computed tomography (PET/CT) imaging technique is considered to be an advanced technique that emerged recently and has been successfully used to guide several procedures like obtaining biopsies and ablating tumors. In this review, we will thoroughly discuss the indications, uses, and advantages of guiding biopsies with PET/CT techniques, with main focus on the field of oncology. PET/CT techniques are considered to be emerging imaging modalities that have significantly improved diagnostic accuracy of biopsies. The most important advantage of using PET/CT imaging to guide biopsies is its ability to provide accurate visualization of the lesion, with immediate assessment of the procedure following its end. On the other hand, this technique still has some limitations. Most importantly, the significant exposure to radiation to both the patient and the physician.
