The Extent of Perfusion–F18-Fluorodeoxyglucose Positron Emission Tomography Mismatch Determines Mortality in Medically Treated Patients With Chronic Ischemic Left Ventricular Dysfunction

Journal of the American College of Cardiology, 2005
The purpose of this study was to assess the determinants of mortality in a large group of patients with ischemic cardiomyopathy who are treated medically and the impact of the extent of viable tissue on prognosis.Whether the presence of viability drives mortality in patients with ischemic cardiomyopathy who are treated medically and whether the extent ...

The effect of fasting on Positron Emission Tomography (PET) imaging [PDF]

Journal of Fasting and Health, 2014
As a nuclear approach, Positron Emission Tomography (PET) is a functional imaging technique which is based on the detection of gamma ray pairs emitted by a positron-emitting radionuclide.

F18-fluorodeoxyglucose positron emission tomography in the context of other imaging techniques and prognostic factors in multiple myeloma

Blood, 2009
AbstractF18-fluorodeoxyglucose positron emission tomography (FDG-PET) is a powerful tool to investigate the role of tumor metabolic activity and its suppression by therapy for cancer survival. As part of Total Therapy 3 for newly diagnosed multiple myeloma, metastatic bone survey, magnetic resonance imaging, and FDG-PET scanning were evaluated in 239 ...

Granulomatous Lung Nodule Mimicking as Metastasis on F18 Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography in a Case of Adrenocortical Carcinoma

Indian Journal of Nuclear Medicine, 2021
A variety of fungal pulmonary infections can produce radiologic findings that mimic malignancy. Distinguishing these infectious lesions from malignancy remains challenging for physicians. We describe one such case where fungal lung nodule mimicked metastasis on fluorodeoxyglucose positron emission tomography/computed ...

Anatomo-radiological correlation using 18-FDG-PET in abdominal sepsis model in rats. A preliminary study [PDF]

Acta Cirúrgica Brasileira, 2017
Purpose: To examine a correlation of micro-PET images with photographic images of the digestive organs in abdominal sepsis model. Methods: Male Wistar rats weighing 265±18g were used. Abdominal sepsis was induced by ligature and cecal puncture.

Prostate cancer and sarcoma: Challenges of synchronous malignancies

Radiology Case Reports, 2020
Synchronous primary malignancies are a rare finding which can be difficult to diagnose. We present the case of a 57-year-old patient with a high prostate specific antigen who was found to have prostate cancer on subsequent magnetic resonance imaging.

Reconstructed spatial resolution and contrast recovery with Bayesian penalized likelihood reconstruction (Q.Clear) for FDG-PET compared to time-of-flight (TOF) with point spread function (PSF) [PDF]

, 2020
BACKGROUND: Bayesian penalized likelihood reconstruction for PET (e.g., GE Q.Clear) aims at improving convergence of lesion activity while ensuring sufficient signal-to-noise ratio (SNR).

Fluorodeoxyglucose F18 Positron Emission Tomography in Progressive Apraxia of Speech and Primary Progressive Aphasia Variants

Archives of Neurology, 2010
To determine patterns of hypometabolism on fluorodeoxyglucose F18 positron emission tomography (FDG-PET) in patients with progressive apraxia of speech (PAS) and primary progressive aphasia (PPA) variants and to use these patterns to further refine current classification.We identified all patients who had FDG-PET and PAS or PPA who were evaluated by an
