Resumen
The accuracy of positron emission tomography (PET) imaging is hampered by the partial volume effect (PVE), which causes image blurring and sampling. The PVE produces spillover phenomena, making PET analysis difficult. Generally, the PVE values vary based on reconstruction methods and filtering. Thus, selection of the proper reconstruction and filtering method can ensure accurate and high-quality PET images. This study compared the values of factors (recovery coefficient (RC), uniformity, and spillover ratio (SOR)) associated with different reconstruction and post-filtering methods using a mous

METHODS We used a 0.2-T Magnetom Open scanner (Siemens Medical Solutions, Erlangen, Germany) that was located in a radiofrequency-shielded operating theater for intraoperative MRI. The head of the patient was placed in the fringe field of the scanner, so that standard microinstruments could be used. In transsphenoidal surgery, T1-weighted coronal and sagittal images were acquired. In transcranial surgery, a three-dimensional, gradient echo, T1-weighted, fast

Resumen
Previously, radioimmunoassay (RIA) has been the only assay to measure insulin-like growth factor-1 (IGF-1) to diagnose hypersomatotropism (HS). Due to radiation concerns, availability, and the cost of IGF-1 RIA, validation of assays for automated analysers such as a chemiluminescent immunoassay (CLIA) is needed. The aim of this study was to validate a CLIA for measurement of feline IGF-1 (IMMULITE 2000® XPi, Siemens Medical Solutions Diagnostics, Malvern, PA, USA) compared to IGF1 RIA, establish reference interval (RI), and determine a cut-off value for diagnosis of HS in diabetic cats.

Introduction: Corticospinal tracts (CST) forms the basis of motor neurophysiology after stroke. Motor skill recovery has been correlated well to the microstructural properties of CST in both hemispheres. Functional imaging has opened up new possibilities of imaging functionality of cortex and fiber tracts in the brain. We studied therapy-induced changes in blood oxygenation level-dependent (BOLD) and DTI imaging on 20 chronic stroke patients at baseline, 8, and 24 weeks. Settings and Design: All the patients were subjected to MR imaging on a 1.5 T MR scanner. We used block design for BOLD with

Resumen
Introduction: Fibrin degradation products, D-Dimer and X-oligomers, are biomarkers for activation of coagulation. D-Dimer testing is recommended as an additional diagnostic tool for proximal deep vein thrombosis (DVT) and pulmonary embolism (PE), in conjunction with clinical presentation and pre-test probability (Lim, et al. Blood Adv. 2018). D-Dimer levels naturally increase in patients over the age of 50 years, which reduces the specificity of D-Dimer levels as a diagnostic aid for proximal DVT and PE in older patients. We conducted a study to assess the diagnostic accuracy of the Tina-quant

Abstract Background: Many patients with sickle cell disease (SCD) require a surgical splenectomy for repeat splenic sequestration or hypersplenism, resulting in worsening anemia and/or thrombocytopenia, or abdominal discomfort. Higher rates of thrombosis, pain crises and acute chest syndrome (ACS) have been reported following surgical splenectomy, although the reasons for this are not known. We hypothesize that this clinical worsening post-splenectomy is due to hemorheological changes; studies of the effects of surgical splenectomy on hemorheology in non-SCD animal models found significant red

Avascular necrosis (AVN) is a serious complication of sickle cell disease (SCD) that can lead to significant morbidity including chronic pain and physical impairment with treatment depending on the patient's pain severity and functional limitation. Patient age, hemoglobin levels, and abnormal rheology, particularly high blood viscosity, or thickness, and percentage of dense red blood cells, defined as cells >1.11 mg/mL have been identified as risk factors for the development of AVN, but their contributions to the subsequent clinical course has not been described.

Shear-Wave Elastography (SWE), an ultrasound technique used to quantify the stiffness of a lesion, showed promising results to improve the diagnostic performance of B-mode breast ultrasound but also to miss some cancers.
