Dual modality imaging of positron emission tomography-computed tomography (PET-CT) in evaluation of postoperative renal cancer patients

Abstract Objective The aim of our study was to determine the role of PET-CT in detection of recurrence and metastasis of renal cell carcinoma. Patients and methods Our study included twenty patients with renal cell carcinoma. All patients were from those attending to radio-diagnosis department in Sharq El Madina Hospital in Alexandria referred for PET/CT study. The following were done for all patients: Careful history taking, clinical examination, ultrasound, enhanced CT and PET/CT. Results One patient (5%) had positive PET/CT findings at different bone sites with high metabolic activity however these lesions were negative at CECT without any anatomical changes neither lytic nor sclerotic changes could be detected at these bone sites, with sensitivity, specificity and accuracy of PET/CT were 100%, 83% and 95% respectively. Conclusion PET/CT had advantage to PET and CT alone, making it an appropriate imaging technique in recurrence detection, therapeutic assessment and follow up of patients with renal cell carcinoma.
