Cristian A Linte, Ziv R Yaniv
While the term "image-guided surgery" has gained popularity fairly recently, the use of imaging for medical interventions dates as far back as the beginning of the 20th century. Dr. George H. Gray of Lynn, Massachusetts, reported in his 1908 article "X-rays in Surgical Work," published in volume 2 of the Journal of Therapeutics and Dietetics, that "the one great stride in the handling of difficult cases was the accurate diagnosis made possible by the use of the X-rays." His story points to the day when a seamstress presented to his office with a broken sewing needle embedded in her hand...

PURPOSE: This study aims to compare image quality, radiation dose, and the influence of the heart rate on image quality of high-pitch spiral coronary computed tomography angiography (CCTA) using 128-slice (second generation) dual-source CT (DSCT) and a 192-slice DSCT (third generation) scanner. MATERIALS AND METHODS: Two consecutive cohorts of fifty patients underwent CCTA by high-pitch spiral scan mode using 128 or 192-slice DSCT. The 192-slice DSCT system has a more powerful roentgen tube (2 × 120 kW) that allows CCTA acquisition at lower tube voltages, wider longitudinal coverage for faster table speed (732 m/s), and the use of iterative reconstruction...

On the 4th July, 1896, in his medical office of Les Échelles (Savoie, France), Victor Despeignes performed the very first radiotherapy against cancer, documented by indisputable proofs. However, the intellectual and practical approach that leads to this first radiotherapy may appear unexpected to date. Indeed, it is likely that the treatment that Despeignes applied to his neighbour, who did not suffer from stomach cancer, was born with the indirect support of the Lumière brothers, on the basis of a biological theory (the parasitory theory of cancer) that is irrelevant today, with an experimental protocol based on experiments performed on tuberculosis et in a bifractionated model linked by the constraints of a district medical doctor...

PURPOSE: After reconstructing a torn ACL with a soft tissue allograft, the long-term healing process of graft maturation following the short-term healing process of graft incorporation into the bone tunnels might lead to recurring instability and concomitant decreases in the activity level, function, and patient satisfaction. Relying on roentgen stereophotogrammetric analysis (RSA), the primary purpose was to determine whether anterior laxity increased and whether patient-reported outcomes declined between 1 and 7 years for a particular graft construct, surgical technique, and rehabilitation programme...

Purpose: Radiology represents a highly relevant part of undergraduate medical education from preclinical studies to subinternship training. It is therefore important to establish a content base for teaching radiology in German Medical Faculties. Materials and Methods: The German Society of Radiology (DRG) developed a model curriculum for radiological teaching at German medical universities, which is presented in this article. There is also a European model curriculum for undergraduate teaching (U-level curriculum of the European Society of Radiology)...

PURPOSE: Current standard methods to quantify disc height, namely distortion compensated Roentgen analysis (DCRA), have been mostly utilized in the lumbar and cervical spine and have strict exclusion criteria. Specifically, discs adjacent to a vertebral fracture are excluded from measurement, thus limiting the use of DCRA in studies that include older populations with a high prevalence of vertebral fractures. Thus, we developed and tested a modified DCRA algorithm that does not depend on vertebral shape...

AIMS: The widely used and well-proven Palacos R (a.k.a. Refobacin Palacos R) bone cement is no longer commercially available and was superseded by Refobacin bone cement R and Palacos R + G in 2005. However, the performance of these newly introduced bone cements have not been tested in a phased evidence-based manner, including roentgen stereophotogrammetric analysis (RSA). PATIENTS AND METHODS: In this blinded, randomised, clinical RSA study, the migration of the Stanmore femoral component was compared between Refobacin bone cement R and Palacos R + G in 62 consecutive total hip arthroplasties...

In their everyday practical clinical work cardiovascular surgeons sometimes have to deal with patients at extremely high risk of both percutaneous coronary interventions (PCIs) and direct myocardial revascularization. A method of choice in such situations may become a PCI supported by artificial circulation (AC), for which foreign and Russian authors propose using systems of prolonged extracorporeal membrane oxygenation (ECMO). The present work was aimed at sharing our experience with using standard systems of AC and their modifications (mini-circuit systems) for performing high-risk PCIs...

Radiotherapy is 120 years old. A few months only after the discoveries of Roentgen, Becquerel and Marie and Pierre Curie, a few scientists tried to use the newly discovered rays to treat patients. The question of the name of the first "radiation therapist" remains debated. Although often proposed, Emil Grubbé from Chicago seems to have been disqualified. Leopold Freund from Vienna treated a benign cutaneous lesion. Finally, Victor Despeignes from Lyon appears to be the most serious candidate, having treated in 1896 a gastric cancer, and obtaining a very significant tumour regression...

PURPOSE: dinamic roentgen stereophotogrammetric analysis (RSA), a technique currently based only on customized radiographic equipment, has been shown to be a very accurate method for detecting three-dimensional (3D) joint motion. The aim of the present work was to evaluate the applicability of an innovative RSA set-up for in vivo knee kinematic analysis, using a biplane fluoroscopic image system. To this end, the Authors describe the set-up as well as a possible protocol for clinical knee joint evaluation...

INTRODUCTION: Radiology was founded on a technological discovery by Wilhelm Roentgen in 1895. Teleradiology also had its roots in technology dating back to 1947 with the successful transmission of radiographic images through telephone lines. Diagnostic radiology has become the eye of medicine in terms of diagnosing and treating injury and disease. This article documents the empirical foundations of teleradiology. METHODS: A selective review of the credible literature during the past decade (2005-2015) was conducted, using robust research design and adequate sample size as criteria for inclusion...

INTRODUCTION: Cementless fixation of the tibial component is critical as reduced initial stability leads to implant failure. In this experimental in vitro study, a new fixation method of the tibial component using polyaxial locking screws is evaluated using Roentgen stereophotogrammetric analysis (RSA). MATERIALS AND METHODS: A special prototype of a tibial component with four polyaxial locking screws was tested on 10 fresh-frozen human tibia specimens. The components were tested with an axial load of 2000 N for 10,000 cycles...

Turner syndrome (TS) is a genetic disorder of females with a prevalence of 1/2000-3000 live female births. The aim of this study was to compare cephalometric variables from adult women diagnosed with TS to a standardized reference group of 31-year old healthy women, and to evaluate the possible effects of human growth hormone (hGH) therapy in women with TS. Registered TS subjects in the Southeast region of Sweden were invited to take part in the study. Twenty-one women aged 36 ± 13(18-57) years accepted participation...

A number of different software programs are used to investigate the in vivo wear of polyethylene bearings in total hip arthroplasty. With wear rates below 0.1mm/year now commonly being reported for highly cross-linked polyethylene (XLPE) components, it is important to identify the accuracy of the methods used to measure such small movements. The aims of this study were to compare the accuracy of current software programs used to measure two-dimensional (2D) femoral head penetration (FHP) and to determine whether the accuracy is influenced by larger femoral heads or by different methods of representing the acetabular component within radiostereometric analysis (RSA)...

BACKGROUND: Single or biplanar video radiography and Roentgen stereophotogrammetry (RSA) techniques used for the assessment of in-vivo joint kinematics involves application of ionizing radiation, which is a limitation for clinical research involving human subjects. To overcome this limitation, our long-term goal is to develop a magnetic resonance imaging (MRI)-only, three dimensional (3-D) modeling technique that permits dynamic imaging of joint motion in humans. Here, we present our initial findings, as well as reliability data, for an MRI-only protocol and modeling technique...
