OBJECTIVE: F-FDG PET/CT provides information on disease extension and activity in neoplastic and inflammatory conditions. So far, little is known about whether SUVmax of a reference lesion can allow a prognosis to be given regarding patient-specific outcome parameters in complex cases of tuberculosis (TB). METHODS: We retrospectively identified 37 patients (21 men, 16 women; mean age, 50.4 years) who underwent F-FDG PET/CT for the evaluation of active TB before treatment initiation...

BACKGROUND: Fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) has become a preferred imaging modality for the evaluation of solitary pulmonary nodule (SPN), particularly in the developed world. Since FDG can concentrate in infective/inflammatory lesions, the diagnostic utility of FDG-PET can be questioned, particularly in regions endemic for infectious decisions. AIM: To evaluate the accuracy of FDG-PET/CT in evaluation of SPNs in a population endemic for infectious disease and to assess if regional variations have an impact on its effectiveness...

Pulmonary tuberculosis infects one-third of world's population and is responsible for the high mortality and morbidity in developing countries. The presence of a high number of macrophages and lymphocytes in active tuberculosis granulomas is associated with high uptake of 18F-fluoro-2-deoxy-d-glucose on PET imaging mimicking lung cancer. In many cases, radiological features of pulmonary tuberculosis are undistinguishable from lung cancer, which makes the diagnosis difficult. Clinical history and computed tomographic (CT) findings on a hybrid PET/CT are as important as findings on a PET in the diagnosis of lung cancer...

Biomarkers for tuberculosis treatment outcome will assist in guiding individualized treatment and evaluation of new therapies. To identify candidate biomarkers, RNA sequencing of whole blood from a well-characterized TB treatment cohort was performed. Application of a validated transcriptional correlate of risk for TB revealed symmetry in host gene expression during progression from latent TB infection to active TB disease and resolution of disease during treatment, including return to control levels after drug therapy...

INTRODUCTION: Whole body PET CT is an important investigation tool in malignancy patients and helps in ascertaining the metabolic activity and exact stage of the disease. However, like any other investigation, false positive results do exist and certain diseases other than cancer may show increased uptake. Hence, a careful evaluation of PET CT and clinical correlation in malignancy patients is a must to accomplish the suitable treatment. METHODS: In this retrospective observational study, seven cases of cancer with concomitant tuberculosis were included...

Asymptomatic pulmonary tuberculosis (PTB) mimicking lung cancer is rare and has been documented in few studies. Accurately diagnosing this atypical disease remains an enormous challenge for clinicians. The aim of the present study was to characterize asymptomatic patients with PTB who were initially diagnosed with lung cancer according to their chest computer tomography (CT) or whole-body 18F-fludeoxyglucose-positron emission tomography-computer tomography (PET-CT) presentations. The clinical characteristics and radiographic features of patients with PTB were analyzed and compared to those of patients with lung cancer...

In the past two decades, it has become increasingly clear that non-human primates, specifically macaques, are useful models for human tuberculosis (TB). Several macaque species have been used for TB studies, and questions remain about the similarities and differences in TB pathogenesis among macaque species, which can complicate decisions about the best species for a specific experiment. Here we provide a quantitative assessment, using serial positron emission tomography and computed tomography (PET-CT) imaging and precise quantitative determination of bacterial burdens, of low-dose M...

Mycobacterium tuberculosis remains the number one infectious agent in the world today. With the emergence of antibiotic resistant strains, new clinically relevant methods are needed that evaluate the disease process and screen for potential antibiotic and vaccine treatments. Positron Emission Tomography/Computed Tomography (PET/CT) has been established as a valuable tool for studying a number of afflictions such as cancer, Alzheimer's disease, and inflammation/infection. Outlined here are a number of strategies that have been employed to evaluate PET/CT images in cynomolgus macaques that are infected intrabronchially with low doses of M...

Tuberculosis is a systemic disease which involves skeletal and articular system very rarely. Osteoarticular tuberculosis commonly occurs in the vertebral column and more rarely in the sacroiliac joints. In this study, we report a 44-years-old male patient with low-grade fever, malabsorption syndrome, abdominal and pelvic ascites and low-back pain, that underwent (18)F-FDG PET/CT for identifying the cause of signs and symptoms after a negative abdominal CT and negative thorax radiography. The study revealed increased tracer uptake at the peritoneal ascites and at the right sacroiliac joint in absence of bone alteration suggesting a sacroiliitis...

Positron emission tomography and computed tomography imaging (PET/CT) is an increasingly valuable tool for diagnosing tuberculosis (TB). The glucose analog [(18)F]fluoro-2-deoxy-2-d-glucose ([(18)F]-FDG) is commonly used in PET/CT that is retained by metabolically active inflammatory cells in granulomas, but lacks specificity for particular cell types. A PET probe that could identify recruitment and differentiation of different cell populations in granulomas would be a useful research tool and could improve TB diagnosis and treatment...

A 53-year-old woman from Southern India presented with weight loss, anorexia, fever and asthenia. Whole body positron emission tomography/computed tomography (PET-CT) showed fluorodeoxyglucose-avid mediastinal and abdominal lymphadenopathy with hepatic, splenic, parotid and lacrimal glandular inflammations. Endoscopic ultrasound-guided fine needle aspiration of subcarinal lymph node showed non-caseating granulomas. Initial serum ACE level was elevated but with normal calcium. Despite the suspicion of sarcoidosis, a trial of antituberculosis therapy was started empirically due to similar presentations of disseminated tuberculosis (TB) in this high endemic area...
