Background: The role of fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG-PET/CT) in the surgical approach solitary pulmonary nodule (SPN) is still debated, as increased metabolic avidity lesion was not a sure sign malignancy. purpose this study to evaluate effectiveness 18F-FDG-PET/CT characterization SPN based on analysis most recent data literature.

18F-Fluorodeoxyglucose-positron emission tomography/computed tomography is a noninvasive imaging modality that appears to have a high negative-predictive value for malignancy in assessing solid splenic masses discovered on conventional imaging modalities. Histological sampling is recommended for fluorodeoxyglucose-avid splenic masses, as the main differential diagnosis includes malignancy, eith...

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 ...

To the Editor: Dermatopathic lymphadenitis (DL) represents a rare benign lymphatic hyperplasia commonly associated with exfoliative or eczematoid dermatitis. DL was also reported to be a potential mimicker of lymphoma.[1] Here, we report the 18F‐fluorodeoxyglucose (18F‐FDG) positron emission tomography/ computer tomography (PET/CT) results and the histological findings of a 40‐year‐old female p...

BACKGROUND Benign hyperplastic thymus is a rare but important differential diagnosis of anterior mediastinal lesions. Histological and radiological criteria are used to distinguish this benign condition from other malignant diseases but have their limitations, and biopsy of mediastinal masses can be risky. We report for the first time the diagnostic value of fluorodeoxyglucose 18F positron emis...

objective(s): we performed a phase iia clinical trial of trans-1-amino-3-18ffluoro-cyclobutane carboxylic acid (anti-18f-facbc), a synthetic amino acid analog for pet, in patients with metastatic prostate cancer. methods: the study subjects consisted of 10 untreated prostate cancer patients having lymph node and/or bone metastasis. five patients underwent whole-body pet 5 and 30 min after intra...

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...

invasive apocrine carcinoma (iac) of the breast is a rare subtype of breast malignancy. its incidence is not well known, but it is approximately less than 1% to 4%. for these reasons, there are few reports and little information on the radiologic appearance of iac. furthermore, most of the case reports show malignant features which are similar to invasive ductal carcinoma (idc). we present a ra...

Apart from the historical and clinical relevance of positron emission tomography (PET) with 18F-fluorodeoxyglucose (18F-FDG), various other new tracers are gaining a remarkable place in functional imaging. Their contribution to clinical decision-making is irreplaceable in several disciplines. In this brief review we aimed to describe the main non-FDG PET tracers based on their clinical relevanc...

Objective(s): Use of a positron emission tomography (PET)/single-photonemission computed tomography (SPECT) system facilitates the simultaneousacquisition of images with fluorine-18 fluorodeoxyglucose (18F-FDG) andtechnetium (99mTc)-tetrofosmin. However, 18F has a short half-life, and 511keV Compton-scattered photons are detected in the 99mTc energy window.Therefore, in this study, we aimed to ...
