H9N2 avian influenza virus has been continuously circulating among poultry and can infect mammals, indicating that this virus is a potential pandemic strain. During influenza pandemics, secondary bacterial (particularly pneumococcal) pneumonia usually contributes to excessive mortality. In the present study, we observed the dynamic effect of H9N2 virus infection on host defense against secondary pneumococcal infection in mice. BALB/c mice were intranasally inoculated with 1.2 × 105 PFU of H9N2 virus followed by 1 × 106 CFU of Streptococcus pneumoniae at 7, 14, or 28 days post-H9N2 infection (dpi). The bacterial load, histopathology, body weight, and survival were assessed after pneumococcal infection. Our results showed that H9N2 virus infection had no significant impact on host resistance to secondary pneumococcal infection at 7 dpi. However, H9N2 virus infection increased pulmonary pneumococcal clearance and reduced pneumococcal pneumonia-induced morbidity after secondary pneumococcal infection at 14 or 28 dpi, as reflected by significantly decreased bacterial loads, markedly alleviated pulmonary histopathological changes, and significantly reduced weight loss in mice infected with H9N2 virus followed by S. pneumoniae compared with mice infected only with S. pneumoniae Further, the significantly decreased bacterial loads were observed when mice were previously infected with a high dose (1.2 × 106 PFU) of H9N2 virus. Also, similar to the results obtained in BALB/c mice, improvement in pulmonary pneumococcal clearance was observed in C57BL/6 mice. Overall, our results showed that pulmonary pneumococcal clearance is improved after resolution of H9N2 virus infection in mice.Introduction The advanced development of iterative image reconstruction enables the absolute quantification of single-photon emission computerised tomography/computed tomography (SPECT/CT) studies by incorporating the compensation for a collimator-detector response, attenuation, and scatter into the reconstruction process. This study aimed to assess the quantitative accuracy of SPECT/CT based on the different levels of 99mTc activity (low/high) on the standardised uptake value (SUV) measurement for different SUV metrics (SUVmean, SUVmax, SUV0.6 max, and SUV0.75 max). Methods A Jaszczak phantom equipped with six fillable spheres was filled with low- and high activity phantom setup at 14 and 110 ( Backgroundsphere) ratios. The low- and high activity concentration phantom setups consisted of ≈10 and ≈60 kBq/ml background, respectively, at both ratios. The fixed-size volume-of-interest (VOI) based on the diameter of each sphere was drawn on SPECT using various metrics for SUV quantification purposes. Results The ering.The emergence of PET and MRI as a hybrid modality has generated widespread interest in the technology and techniques. Although adoption and use are unlikely to be as expansive as for PET and CT hybrid systems, PET/MRI is an important modality that requires broad insight for nuclear medicine professions generally and deeper insight for those engaged in PET/MRI practice. This article provides insight into the considerations and challenges associated with establishing a PET/MRI facility. Each clinical site will present unique requisites for establishing a PET/MRI facility, and indeed, each PET/MRI vendor will have specific site requirements. selleck chemicals Nonetheless, this article provides general insight into common considerations but should not be considered exhaustive. Here, development of the facility, staffing of the facility, and implications of both radiation and MRI safety are considered from the context of facility design. Given that the nature of PET is well established among the readership of this journal, the article provides an emphasis on MRI factors. This article is the first in a 4-part integrated series sponsored by the PET/MR and Publication Committees of the Society of Nuclear Medicine and Molecular Imaging-Technologist Section. In the subsequent 3 parts, PET/MRI will be explored on the basis of technology principles (part 2), protocols and procedures (part 3), and applications and clinical cases (part 4).The challenges of hybridizing position emission tomography (PET) and magnetic resonance imaging (MRI) as a simultaneous modality have been largely overcome in recent times. PET hybridized with magnetic resonance (MR) has seen the emergence of PET/MR imaging systems in the clinical setting and with it comes a responsibility to adapt appropriate facility design, safety practices, protocols and procedures, and clinical opportunity. This manuscript provides an insight into the considerations and challenges associated with PET/MR technology. Given the nature of PET is well established amongst the readership of this journal, the manuscript provides an introduction to the foundations of MRI instrumentation and emphasis on specific technological aspects of PET/MR systems. This manuscript is the second in a four-part integrated series sponsored by the SNMMI-TS PET/MR Task Force in conjunction with the SNMMI-TS Publication Committee; building on the previous article on establishing a facility (part 1). In subsequent editions, PET/MRI will be explored based on protocols and procedures (part 3), and applications and clinical cases (part 4).Rotor syndrome (RS) is a benign, inherited, commonly misdiagnosed cause of conjugated hyperbilirubinemia whose identification prevents unnecessary invasive investigations. We present the case of a 3-y-old boy with phenotypic and laboratory findings of RS but negative genetic test results, whose diagnosis was confirmed by hepatobiliary scintigraphy.Breast is unusual site for metastasis from malignant tumors though may be the first manifestation of extra-mammary malignancy with primary typically arising from lung, melanoma, ovary and lymphoma. Breast metastasis is extremely rare from thyroid carcinoma and may take years to develop as differentiated thyroid carcinoma are usually indolent, slow growing and metastasize to lymph nodes, lungs and bones. Here is a middle-aged woman (post-subtotal thyroidectomy for multi-nodular goitre 24 years ago) showing discordant FDG and iodine avidity in proven metastatic disease involving lymph nodes, bones, spleen and breast on whole-body radioiodine and FDG-PET/CT due to tumor heterogeneity.
