Intracerebral Glioma Using PET/CT/(MRI) with [18F]TFAHA

Over the past two decades, several studies have demonstrated that GBM progression and recurrence is to epigenetic mechanisms including; mutations in IDH1/IDH2 genes, epigenetic modifying enzymes, histone deacetylases (HDACs); histone methyltransferases (HMTs); DNA methyltransferases (DNMT) and various DNA demethylases. Many novel inhibitors of these key epigenetic regulatory enzymes have been developed and tested in clinical…

Diagnostic Efficacy And Safety Of Gadoxetate Disodium VS Gadobenate

The aim of this study is to evaluate the diagnostic efficacy and safety of gadoxetate disodium vs gadobenate dimeglumine in patients with known or suspected focal liver lesions. This was a prospective, multicenter, double-blind, randomized, inter-individual Phase III study. The primary target technical efficacy is already publish. Here, secondary efficacy parameters sensitivity and specificity and…

Visceral Adipose Tissue By Computed Tomography And Magnetic Resonance Imaging

To evaluate the feasibility of quantifying visceral adipose tissue (VAT) on computed tomography (CT) and magnetic resonance imaging (MRI) scans, using freeware, as well as calculating intraobserver and interobserver reproducibility. We quantified VAT in patients who underwent abdominal CT and MRI at our institution between 2010 and 2015, with a maximum of three months between the two examinations.…

Diagnostic Imaging Methods For The Lymphadenopathies In HIV-Infected

To assess the percent agreement between diagnostic imaging modalities for the evaluation of lymphadenopathies in HIV-infected/AIDS patients.This was an open, comparative, prospective study of diagnostic imaging methods for lymphadenopathy evaluation. We evaluated 30 patients . All underwent ultrasound and computed tomography (CT). Twenty of the patients also underwent magnetic resonance imaging (MRI). Molecular structure We…

MR Volumetry of Lung Nodules

Thoracic computed tomography (CT) is the current reference imaging modality for the detection; of nodules as well as for the follow-up of indeterminate pulmonary nodules incidentally discovered or occurring in a malignancy context. While 2D measurements are typically using in clinical practice; 3D volume measurements are growing in importance due to evidence that 3D volumetry…

18F-GP1 PET/CT

PET/CT High Detection Rate For Diagnosis Of Acute Venous Thromboembolism

A first-in-human study featured in the February issue of The Journal of Nuclear Medicine reports that the novel positron; emission tomography/computed tomography (PET/CT) tracer 18F-GP1 showed excellent image quality and a high detection rate for the diagnosis of acute venous thromboembolism (VTE). Well-tolerated in patients; 18F-GP1 PET/CT also identified blood clots in distal veins of…

Evaluation Of Patients With Moyamoya Disease By PET/CT

Moyamoya disease is a disease in which certain arteries in the brain are constricted. Blood flow is blocked by the constriction, and also by blood clots (thrombosis). Patients with Moyamoya Disease (MMD) need the hemodynamic evaluation of vascular territories at risk of stroke. Today’s investigative standards include H215O PET/CT with pharmacological challenges with acetazolamide (ACZ). Recent…

Imaging Use For Low Back Pain By Ontario Primary Care Clinicians

At any one time, one in every five Canadians has low back pain (LBP), and LBP is one of the most common health problems in primary care. Guidelines recommend that imaging not be routinely performed in patients presenting with LBP without signs or symptoms indicating a potential pathological cause. Yet imaging rates remain high for…

8F-FDG PET/CT On The Management Of Gynecologic Cancers

The detection rate of gynecologic malignancies is increasing every year; mortality associated with gynecological cancers is high mainly due to detection of disease at an advanced stage. Endometrial cancer is the most common malignancy of the female reproductive system. Ovarian cancer ranks as the fifth highest cause of cancer-related death among women and in some…

18F-FDG PET CT

FDG PET CT Scan In Vertebral Hemangioma

18F-fluorodeoxyglucose positron emission tomography-computed tomography (18F-FDG PET CT) is an established method for the staging of carcinomas. The bone scan is an old method to detect skeletal metastasis. Both the modalities are usually normal in vertebral hemangiomas. However, there have been case reports of increased osteoblastic activity on bone scan; with normal metabolic activity on…

PET

Metabolic And Functional In Adolescent Brain By PET/CT

Brain development is a dynamic and complex process, including the change of brain volume and morphology, metabolism; expression of receptors and transporters, and function. A number of investigations indicate brain regional growth with changes of cortical thickness during brain development and maturation using MR. However, metabolic and functional changes associated with brain development and maturation…
