BACKGROUND Relapsing polychondritis (RP) is an uncommon autoimmune inflammatory disease that may affect cartilage throughout the body. CASE REPORT We report on a case of fever of unknown origin in which 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) was performed to make a diagnosis of RP. CONCLUSION Our case demonstrates that the use of 18F-FDG PET...

18F fluorodeoxyglucose positron emission tomography (18F-FDG PET) imaging is a useful modality in detecting various tumors, including renal cell carcinoma. We evaluated a patient with renal pelvic tumor (transitional cell carcinoma) with multiple metastases using 18F-FDG PET imaging and detected abnormal increased uptake of a right renal pelvic tumor extending to the renal cortex with liver met...

context inherited and sporadic medullary thyroid cancer (mtc) is an uncommon and medically challenging malignancy. even if the extent of initial surgery is deemed adequate, the recurrence rate remains high, up to 50% in most series. measurement of serum calcitonin is important in the follow-up of patients with mtc, and reliably reflects the existence of the disease. evidence acquisition there i...

temporal bone chondroblastoma is an extremely rare benign bone tumor. we encountered two cases showing similar imaging findings on computed tomography (ct), magnetic resonance imaging (mri), and dual-time-point 18f-fluorodeoxyglucose (18f-fdg) positron emission tomography (pet)/ct. in both cases, ct images revealed temporal bone defects and sclerotic changes around the tumor. most parts of the ...

Whole-body imaging with Positron Emission Tomography (PET) using F-18 Fluorodeoxyglucose (18F-FDG) has been widely used along the evaluation and clinical management of neoplasms. The main advantage whole-body 18F-FDG PET in oncology is ability to detect unexpected or incidental tumor sites. purpose this study was determine incidentaloma examination nuclear medicine. This research uses literatur...

18F-fluorodeoxyglucose (18F-FDG) positron emission tomography has become an important tool for detection, staging and management of many types of cancer. Oncology application of 18F-FDG bases on the knowledge that increase in glucose demand and utilization is a fundamental features of cancer. Pasteur effect, Warburg effect and reverse Warburg effect have been used to explain glucose metabolism ...

INTRODUCTION This case of giant cell arteritis is noteworthy because it evaded standard diagnostic criteria and only emerged as fever of unknown origin. In this regard, we present 18F-fluorodeoxyglucose positron emission tomography as a valid diagnostic method. CASE PRESENTATION This case report describes a 58-year-old Caucasian woman who is a cigarette smoker with a 10-week history of fever ...

The kinetics of 18F-fluorodeoxyglucose (18F-FDG) in the monkey brain were monitored, and comparisons were made between the conscious state and when under ketamine and pentobarbital anesthesia. Rhesus monkeys were intravenously injected with 18F-FDG and followed by 60 min of PET scanning. In the conscious state, the 18F-FDG concentration reached a plateau 5 min after intravenous injection. Under...

18F-fluorodeoxyglucose positron emission tomography (18F-FDG-PET) is an evolving tool in the field of oncology. 18F-fluorodeoxyglucose, however, is not a specific tool for malignant tumor that it may also accumulate in benign processes. To avoid false-positive interpretation of 18F-FDG-PET/computed tomography (CT), having knowledge of the potential pitfalls is important.The authors present a ca...

18F-fluorodeoxyglucose ([18F]-FDG) positron emission tomography/computed tomography (PET/CT) is a useful functional image technique to evaluate the disease extent in many cancers, as well differentiate benign from malignant metastasis. We report case of 49-year-old woman with breast cancer and suspected lung metastasis by conventional images. After FDG-PET/CT demonstrating faint, or even no FDG...
