Sirtuin 7 (SIRT7) plays an important role in tumor development, and has been characterized as a potent regulator of cellular stress. However, the effect SIRT7 on sorafenib acquired resistance remains unclear possible anti-tumor mechanism beyond this process HCC not clarified. We examined therapeutic potential determined whether it functions synergistically with to overcome chemoresistance.
To assess the performance of dual energy unenhanced CT in detection acute ischemia after mechanical thrombectomy.Retrospective study, approved by local institutional review board, including all patients that underwent intra-arterial thrombectomy our institution over a period 2 years. The presence and hemorrhage was evaluated three readers. Sensitivity specificity non-contrast weighted sum image (NCCT) virtual reconstructed (VNC) were estimated compared using generalized estimating equations...
Our purpose was to establish whether noninvasive measurement of changes in <sup>18</sup>F-fluoride metabolic flux bone mineral (K<sub>i</sub>) by PET/CT can provide incremental value response assessment metastases breast cancer compared with SUV<sub>max</sub> and SUV<sub>mean</sub>. <b>Methods:</b> Twelve patients starting endocrine treatment for de novo or progressive were included. Static scans acquired 60 min after injection, before 8 wk commencing treatment. Venous blood samples taken at...
To compare radiation dose and image quality of thoracoabdominal scans obtained with a high-pitch protocol (pitch 3.2) iterative reconstruction (Sinogram Affirmed Iterative Reconstruction) in comparison to standard pitch reconstructed filtered back projection (FBP) using dual source CT.114 CT (Somatom Definition Flash, Siemens Healthineers, Erlangen, Germany), 39 thoracic scans, 54 21 abdominal were performed. Analysis three protocols was undertaken; 1 FBP, 3.2 SAFIRE, stellar detectors...
We sought to assess the use of an electro pulmonary nodule (EPN) scanner (FreshMedx, Salt Lake City, UT) in noninvasive characterization nodules using transcutaneous bioconductance. Monocentric prospective study including patients with a identified on chest computed tomography scan. Study protocol approved by institutional review board and written consent was obtained for every patient. 32 (12 females 20 males), average age 65 years, lesion size 33.1 mm (range: 9–123 mm). Data collection...
Objective: Radiographic imaging is an important diagnostic tool in diabetic foot osteomyelitis (DFO). It unknown whether DFO cases diagnosed with conventional X-ray versus positive Magnetic Resonance Imaging (MRI) differ regarding epidemiology and treatment outcome. Theoretically, signs of inflammation on MRI without bone lesions might be easier to treat. Methods: Our clinical pathway for infections discourages the use diagnosis DFO. We compared therapy non-amputated features X-ray, MRI, or...
Abstract To compare 2 incompatible generations of iterative reconstructions from the same raw dataset based on automatic emphysema quantification and noise reduction: a hybrid algorithm called sinogram affirmed reconstruction (SAFIRE) versus model-based advanced modeled (ADMIRE). Raw datasets 40 non-contrast thoracic computed tomography scanners obtained single acquisition SOMATOM Definition Flash unit (Siemens Healthcare, Forchheim) were reconstructed with 3 levels SAFIRE ADMIRE algorithms...
Aim: To test 3D-printed immobilization devices for future use in magnetic resonance-guided focused ultrasound hyperthermia. Material & methods: Using a surface scanner, patient-specific pelvic were 3D printed. The setup reproducibility was measured both on linear accelerator (LINAC) and resonance. An imaging probe used to acquire reference images later once attached into the embedded holder. Results: Prepositioning accuracy tested at LINAC using an optical monitoring MRI showed submillimeter...

Objectives:To identify new magnetic resonance imaging (MRI) patterns in patients with high-grade glioma treated bevacizumab (Avastin®). Methods:The retrospective study was approved by the institutional review board. An extended case series of 27 (19 men, 8 women) age range 22–76 years and an average 52 were studied 1.5T/3T MRI (Siemens scanner Erlangen, Germany). Protocol included axial T1-wi spin echo (SE), T2-wi fast SE, three-dimensional fluid-attenuated inversion recovery (3D FLAIR),...
A 70-year-old male patient underwent an Fluorodeoxyglucose-positron emission tomography-computed tomography for staging of a left parahilar lung neoplasm found during work-up fatigue and asthenia. The scan demonstrated hypermetabolic tumor, pleural effusion 4 bilateral soft tissue lesions the chest wall corresponding to elastofibroma dorsi. Initially, oncologic disease was classified as stage IV because effusion. transbronchial biopsy showed squamous cell carcinoma cytology revealed no...
