21. Double-contrast MRI for the staging of rectal carcinoma: Technical aspects and clinical experience
Abstract : Aim of the study Today´s methods for the staging of rectal carcinoma: ultrasonography with transrectal probe, CT, MRI or MRI with a rectal coil, all have limitations. The aim was therefore to develop a new, double-contrast MRI method for evaluation of rectal carcinoma. READ MORE

22. Studies on the use of digital radiography for the assessment of periapical bone lesions
Abstract : The aim was to study digital radiography and to evaluate the influence of image processing on digital dental radiographs for the assessment of periapical lesions. In four studies, artificial bone lesions were made periapically and interradicularly in the mandibular premolar and molar regions. READ MORE

23. Irreversible electroporation in the liver
Abstract : Introduction: Malignant tumours in the liver are divided into primary liver cancers and liver metastases. Among primary liver cancers, hepatocellular carcinoma (HCC) accounts for 75-85% and is globally the fourth most common cause of cancer related death. Colorectal cancer (CRC) is the second most common cause of cancer related death. READ MORE

24. Estimating polyethylene wear in total hip arthroplasty by using computed tomography and alternative RSA techniques
Abstract : Introduction: Traditionally Total Hip Arthroplasty (THA) components performance, and in particular the performance of the polyethylene liner, is evaluated in 2D by examining plain radiographs or in 3D using Radio Stereo-metric Analysis (RSA). While 2D techniques require only a plain radiograph, they are less accurate. READ MORE

25. Applications of the golden angle in cardiovascular MRI
Abstract : The use of radial trajectories has been seen as a potential solution to highly efficient cardiovascular magnetic resonance imaging (MRI). By acquiring a broad range of spatial frequencies per repetition time, the acquisition is time-efficient and robust against motion. READ MORE
