Aims In preclinical setting, micro-CT is used to provide anatomical information of small animals (e.g. mice), and can be used in conjunction with functional imaging modalities, which provide information on biological processes in tissues. The combination of micro-CT with functional imaging provides localization of the investigated process, i.e. physiology or disease, within the animal and furth...

Background: Pre-clinical investigation of stem cells for repairing damaged myocardium predominantly used rodents, however large animals have cardiac circulation closely resembling the human heart. The aim of this study was to evaluate whether SPECT/CT myocardial perfusion imaging (MPI) could be used for assessing sheep myocardium following an acute myocardial infarction (MI) and response to int...

Interstitial hernias are a rare entity. Most of them are detected incidentally on imaging studies. We present a case of abdominal bowel obstruction secondary to interstitial hernia on the fifth postoperative day of an open incisional hernia repair. Laparoscopy confirmed the diagnosis and led to an accurate treatment avoiding a new laparotomy. In this case, prompt surgical decision based on clin...

Introduction: Recently, magnetic resonance spectroscopic imaging (MRSI), as a functional imaging method, has been used for clinical target volume definition. In this study, we used this method to define the target volume in prostate radiotherapy. Material and Method: In this study, we used images of 20 prostate cancer cases. MRSI and MRI images were fused with CT images. Then, treatment plannin...

Imaging techniques for detection of molecular and cellular processes that precede or accompany lung diseases are needed. Matrix metalloproteinases (MMPs) play key roles in the development of pulmonary pathology. The objective of this study was to investigate the feasibility of in vivo MMP-targeted molecular imaging for detection of lung inflammation and remodeling. METHODS Lung-specific IL-13...

The objective of this study was to estimate the availability of large weight capacity computed tomography (CT) and magnetic resonance imaging (MRI) equipment in US hospitals with emergency departments (EDs) and to evaluate animal facilities as alternate sources of imaging. We conducted a telephone survey of radiology technicians from a random sample of all the US hospitals with EDs (n = 262) an...

solar mini-dimmings can be detect in the extreme ultra-violet coronal eruptions. here, sequences of 171_a images taken by solar dynamic observatory/atmospheric imaging assembaly on 13 june 2010 are used. in this special day, both of coronal mass ejection and prominence were observed. the average velocities and accelerations of 500 mini-dimmings which were detected using on feature based classif...

Stem cell–based therapy offers great promise for a wide range of diseases and injuries that cannot be effectively treated by existing medicine therapies. However, the translation stem cell to clinic is still hampered lack profound understanding about survival, differentiation, migration, homing, fate transplanted cells during therapy. To address these issues, computed tomography (CT) based on n...

UNLABELLED Our goal was to assess the typical appearance of normal liver tissue immediately after radiofrequency ablation (RF-ablation) when imaged with contrast-enhanced ultrasound, CT, MRI, 18F-FDG PET, and PET/CT. METHODS Nineteen RF-ablation sessions were performed on nontumorous liver tissue of 10 Göttingen Mini Pigs. CT, ultrasound, MRI, 18F-FDG PET, and PET/CT were performed immediatel...
