We investigated the effects of nickel oxide nanoparticles (NiONPs) on the pulmonary inflammopathology. NiONPs were intratracheally installed into mice, and lung injury and inflammation were evaluated between 1 and 28 d. NiONPs caused significant increases in LDH, total protein, and IL-6 and a decrease in IL-10 in the BALF and increases in 8-OHdG and caspase-3 in lung tissues at 24h. Airway inflammation was present in a dose-dependent manner from the upper to lower airways at 24h of exposure as analyzed by SPECT.
ConclusionThe nigrostriatal dopaminergic degeneration might affect the secondary visual pathway, leading to visual dysfunctions in PD.
ConclusionParathyroid 4DCT can aid surgical planning in cases without concordant SeS/US findings; however, the introduction of 4DCT as a second-line test did not change our overall cure rate or rate of minimally invasive parathyroidectomy. The role of 4DCT as the primary localization study for pHPT merits further investigation.
This study presents a methodology to calculate the T/N ratio using global information from the SPECT. The T/N ratio is estimated by establishing uptake thresholds consistent with previously performed volumetry. This dose calculation method was validated against three-dimensional voxel dosimetry, and was also compared with the standard partition method based on freehand regions of interest (ROI) outlining on SPECT slices. Both comparisons were done on a sample of 20 actual cases of hepatocellular carcinoma treated with resin microspheres. The proposed method and the voxel dosimetry give very similar results. Differences are...

Spuler A discussion is presented on the current use of radionuclides for evaluation of coronary artery disease in relation to other available techniques. The review is focused on coronary artery disease risk stratification employing single photon emission computed tomography and positron emission tomography, as well as on ischemic cardiomyopathy and myocardial viability applications. Concepts are presented regarding coronary...

García-Concha, S. Arevalo-Leal Vascular graft infections are a rare complication in this type of procedure. However, when they do occur, they usually have high morbidity, and even a high mortality. Proper identification and location is crucial for the appropriate and early management, whether medical or surgical, thus knowledge of the right tools is paramount. Nuclear medicine studies play an important r...
Authors: Nakaya K, Onoguchi M, Nishimua Y, Kiso K, Otsuka H, Nouno Y, Shibutani T, Yasuda E Abstract Background: Prone single photon emission computed tomography (SPECT) is suitable for evaluating the cardiac inferior wall as it suppresses attenuation artifacts from the diaphragm. The solid-state dedicated cardiac camera (D-SPECT) allows upright imaging, which can also be used to avoid attenuation artifacts from the diaphragm. We compared prone and upright imaging for inferior wall evaluation using (201)TlCl myocardial perfusion SPECT. Methods: The study targeted 45 patients. The prone imaging group included 23 sub...
Conclusion: All the absorbed doses were comparable to those known for most of the 99mTc studies. 99mTc-exendin(9-39)/octreotide obtained from kit formulations showed high tumor uptake in a patient with a malignant lesion, making it a promising imaging radiopharmaceutical to target GLP-1R and SSTR.
Conclusion: Patients with normal myocardial perfusion scintigraphy in whom ST-segment depression develops during adenosine stress test appear to have no increased risk for future cardiac events compared with similar patients without ECG evidence of ischemia.
