Fluorine-18-fluorodeoxyglucose positron emission tomography (18F-FDG PET) is routinely used mainly for diagnostics and monitoring of many oncological diseases. However, fluorine-18-fluorodeoxyglucose as a radiopharmaceutical is not an exclusively tumour-specific tracer and numerous inflammatory diseases may be evaluated as well. An inflammatory lesion showing high 18F-FDG accumulation is likely...

Gliomas account for almost 80% of primary malignant brain tumors in adults. Magnetic Resonance imaging (MRI) is still the gold standard for diagnosis of brain tumors and brain 99mTc-tetrofosmin Single Photon Emission Computed Tomography (99mTc-tetrofosmin-SPECT) has been established as a useful tool for their evaluation. Fluorine-18–2-fluoro-2-deoxy-d-glucose positron emi...

Chronic lymphocytic leukemia (CLL) is a low-grade B-cell proliferative disease with a generally indolent course. In a few cases, it undergoes transformation and becomes a more aggressive malignancy, such as diffuse large B-cell lymphoma (DLBCL). This process, which is called Richter transformation (RT), is often detected too late and is associated with a poor prognosis. There are multiple molec...

INTRODUCTION Mucoepidermoid carcinoma of the tracheobronchial tree is rare. Such tumors usually present with signs and symptoms of bronchial obstruction. Histologically, they can be classified as high-grade or low-grade tumors. Experience of imaging these tumors with 18fluorodeoxyglucose positron emission tomography-computed tomography (18F-FDG PET-CT) is limited. We present three cases of this...

The fusion of 18-fluorodeoxyglucose (FDG) positron-emission tomography (PET) with computed tomography (CT) offers both anatomic and physiologic delineation of head and neck cancers. PET-CT is useful in the staging of head and neck carcinomas and may identify unsuspected distant metastasis that may alter treatment. PET-CT may also help in target volume delineation during radiotherapy (RT) treatm...

A 74-year-old hemodialysis patient with a history of an atrial septum defect closure, coronary bypass surgery, and a St. Jude aortic prosthetic valve was diagnosed with pneumonia and volume overload. Blood cultures were positive for Listeria monocytogenes, and amoxicillin was given for 2 weeks. Immediately after discontinuation of amoxicillin, fever relapsed. Transthoracic and transesophageal e...

Abstract Background Infective endocarditis is a challenging diagnosis that usually requires cardiovascular image confirmation as part of the approach. 18F-FDG PET/CT an imaging technique more sensible for prosthetic valve when echocardiography inconclusive. Case Summary We present case 35-year-old man who had previous Bentall-De Bono procedure four years prior included biological, INC-type, loc...

BACKGROUND High fasting plasma glucose (FPG) levels before fluorodeoxyglucose (FDG) administration for positron emission tomography/computed tomography (PET/CT) might affect the accuracy of 18-fluoro-deoxy-glucose-positron emission tomography-computed tomography (FDG-PET/CT) in diagnosis of pancreatic lesions. Current guidelines require FPG levels of < 200 mg/dL before FDG administration; howev...

ObjectiveThis study aimed to investigate the value of interim whole-body dynamic 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) Patlak parameters for predicting prognosis patients with diffuse large B-cell lymphoma. To estimate predictive 18F-FDG PET/CT parameter 2-year progression-free survival (PFS) and overall (OS).MethodsThis reports findings 67 lym...

Crossed cerebellar diaschisis (CCD) describes a depression of oxidative metabolism glucose and blood flow in the cerebellum secondary to a supratentorial lesion in the contralateral cerebral hemisphere. PET/MR has the potential to become a powerful tool for demonstrating and imaging intracranial lesions .We herein report 3 cases of CCD imaging using a tri-modality PET/CT–MR setup for investigat...
