Introduction: Orbital metastasis of prostate cancer (PC) is very rare and even more unique in castration-resistant PC (CRPC). In this scenario, choline positron emission tomography/computed tomography (choline PET/CT) is the gold-standard restaging method of choice available in our setting, and new anti-androgens treatments show improvement in overall survival. Case presentation: We report the...

During the last years, a number of novel X-ray imaging and data processing methods have been developed. This work gives an overview of some selected X-ray computed tomography (CT)-developments, which are relevant for research and industry: 1) Advanced CT-data processing and visualization methods: Only through processing, segmentation, evaluation and visualization of CT data, insights of a sampl...

Introduction: The use of a simple tissue analog material in the fabrication of medical computed tomography (CT) imaging phantoms has great potential to help researchers. The purpose of the present study is to develop new gel tissue-equivalent materials and determine whether their CT numbers and relative electron densities vary in CT images obtained by scans at different energie...

introduction delayed splenic rupture (dsr) is an unusual outcome following blunt abdominal trauma. although dsr is defined as bleeding more than 48 hours after blunt trauma in a previously hemodynamically stable patient, a review of the reported cases in the literature shows that in almost all of the cases the initial ct imaging revealed some form of damage to the spleen. case presentation here...

X-ray Computed Tomography (CT) reconstruction from sparse number of views is becoming a powerful way to reduce either the radiation dose or the acquisition time in CT systems but still requires a huge computational time. This paper introduces an approximate Bayesian inference framework for CT reconstruction based on a family of denoising approximate message passing (DCT-AMP) algorithms able to ...

Three-dimensional internal pore structures of various asphalt specimens with varying mix-designs and compaction levels were generated using X-ray Computed Tomography (CT) technique. Pore structure parameters were computed using image processing algorithms and estimated permeabilities using two semi-analytical equations were compared to laboratory-based vertical permeability. Furthermore, an ana...

Coronary arteries are the blood vessels supplying oxygen-rich blood to the heart muscles. Coronary artery calcium (CAC), which is the total amount of calcium deposited in these arteries, indicates the presence or the future risk of coronary artery diseases. Quantification of CAC is done by using computed tomography (CT) scan which uses attenuation of xray by different tissues in the body to gen...
