It is well known that hematopoietic cytokine stimulation can cause increased fluorodeoxyglucose (FDG) accumulation in bone marrow on PET/CT imaging, which simulates that seen in patients with bone marrow metastases. However, increased bone marrow FDG uptake can be caused by other etiologies. We report a patient with operated renal cell carcinoma had no history of hematopoietic cytokine stimulation...
To assess the calcification process of the carotid plaque by 18 F-sodium fluoride PET/CT imaging.A prospectively designed study including 15 patients in whom an atheroma plaque was detected by contrast enhanced CT scan during a neurological work-up was performed. A total of 29 plaques, 19 asymptomatic and 10 symptomatic, were studied. An 18 F-sodium fluoride PET/CT scan was acquired...
A 52-year-old patient, with symptoms of angina in the last month, was referred to undergo a SPECT myocardial perfusion. At an early stage of the exercise test, he showed electrical changes suggestive of inferior ischemia and the scintigraphy images showed intense and extensive inferolateral hypoperfusion during the stress, with complete reversibility at rest. Coronary angiography showed a right coronary...
To evaluate SUV changes in the liver in relation to body mass index (BMI) of patients who undergo whole body PET-CT scans.A retrospective study was performed. The variables studied were injected dose of 18F FDG (mCi), age (years), blood glucose level (mg/dL), height (cm) and weight (kg). BMI was calculated and the SUV mean value was expressed according to gender and BMI. A linear regression...
The current protocols include the bone scintigraphy and choline PET/CT to localize recurrence in patients having elevated serum PSA after treatment for prostate cancer. Both methods show good agreement in the diagnosis of bone metastases; however, conflicting results can be found. We present three cases in which a PET/CT was performed with 18 F-fluoride due to disagreement between the bone...
To characterize the performance of the Biograph mCT PET/CT TrueV scanner with time of flight (TOF) and point spread function (PSF) modeling.The PET/CT scanner combines a 64-slice CT and a PET scanner which incorporates the reconstruction the TOF and PSF information. PET operating characteristics were evaluated according to the standard NEMA NU-2-2007, by expanding some tests. In addition, different...
To describe the process of implementing a Quality Management System according to UNE-EN-ISO 9001:2008 standard in a Nuclear Medicine Department.In February 2008, the committee on internal quality of the department was established, naming a responsible physician. The general operating plan was drawn up, following the requirements established by the ISO 9001:2008 standard. It defined the scope of the...
The 18 F-choline PET-CT (FCH) has better performance in the assessment of patients with prostate cancer than 18 F-FDG could do. However, similarly, it is also not a tumor specific radiotracer.We present four 18 F-FCH PET-CT scans in which false positive findings were correctly assessed after evaluation with CT, clinical parameters and/or histological analysis.
To evaluate the evolutive changes in diastolic function after percutaneous coronary revascularization (PCR) in acute myocardial infarction (AMI), using myocardial perfusion gated SPECT.Thirty-two patients (mean 61.9±9.7 years, 7 women) were studied by two at rest gated SPECT: the first gated-SPECT-1 was performed with an injection of a dose of 99m Tc-tetrofosmin prior to PCR and the second...
The liver has been used as a reference organ for the assessment of abnormal 18 F-fluoro-2-deoxy-d-glucose ( 18 FDG) in the body. Some researchers found that hepatosteatosis significantly changed the hepatic 18 FDG uptake, while others did not. This study investigated whether the liver's 18 FDG uptake was affected by the diffuse fatty infiltration of the liver.A total...
