BACKGROUND: Extensive osteochondritis dissecans (OCD) lesions of the lateral ridge of the trochlea of the femur (LRTF), the most common OCD- affected site in the stifle, have a poor outcome with surgical debridement and can be career ending. The early detection of osteochondrosis lesions and their conservative management holds the promise to enhance outcome. We hypothesise that ultrasonography is a valuable field screening tool to detect and monitor early subclinical LRTF osteochondrosis...

REVIEW
T Grieser, I-M Nöbauer-Huhmann
Posttreatment imaging of primary bone tumours represents a diagnostic challenge for radiologists. Depending on the primary bone tumour common radiological procedures, such as radiography, computed tomography (CT), and magnetic resonance imaging (MRI), are employed. Radiography and CT are particularly useful in benign bone tumours and in matrix-forming bone tumours. MRI comes into consideration with malignant tumour recurrence and tumoral soft tissue infiltration. Bone scintigraphy is of superior importance if a primarily multifocal manifestation of bone tumour or metastasizing tumour disease is suspected...

An optically stimulated luminescence dosemeter was used to compare the surface dose to both eyes from an X-ray delivered frontally to the skull, and the dose could be reduced depending on image acquisition. The detectors were analysed in advance according to each image acquisition method, and the irradiation condition (mA) was obtained to equate the detective quantum efficiency of the two detectors. The surface doses to both eyes were measured in a human phantom. In the detector using the direct conversion method, the surface doses to both eyes were 0...

REVIEW
Catherine M Ruoff, Sharon C Kerwin, Amanda R Taylor
Discospondylitis can affect dogs of any age and breed and may be seen in cats. Although radiography remains the gold standard, advanced imaging, such as CT and MRI, has benefits and likely allows earlier diagnosis and identification of concurrent disease. Because discospondylitis may affect multiple disk spaces, imaging of the entire spine should be considered. There is a lengthening list of causative etiologic agents, and successful treatment hinges on correct identification. Image-guided biopsy should be considered in addition to blood and urine cultures and Brucella canis screening and as an alternative to surgical biopsy in some cases...

REVIEW
Sean Robinson Smith, Ashish Khanna, Eric M Wisotzky
Lung cancer is the number one cause of cancer-related death worldwide, and is often detected in the later stages. Use of low-dose chest computed tomography in at-risk patients provides earlier detection and is being adopted as the standard screening tool, replacing less precise methods of radiography and sputum cytology. In the past, late detection of disease meant that rehabilitation interventions attempted to salvage function and to improve aerobic capacity to the point where patients could tolerate the sometimes-extensive oncologic treatment, including lobectomy or pneumonectomy...

In recent years there has been a significant evolution in the field of cardiovascular implantable electronic devices (CIED). Pacemakers can now be leadless, implantable cardioverter defibrillators can be entirely subcutaneous and implantable loop recorders have become miniaturised. Driven by technological advances and an ageing population implant numbers have also steadily increased. These highly prevalent systems are all radio opaque and are frequently observed on chest radiographs, yet the devices are neither well recognised nor understood...

Introduction: Chronic kidney disease (CKD) is associated with high morbidity and mortality rates, main causes related with cardiovascular disease (CVD) and bone mineral disorder (CKD-BMD). Uremic toxins, as advanced glycation end products (AGEs), are non-traditional cardiovascular risk factor and play a role on development of CKD-BMD in CKD. The measurement of skin autofluorescence (sAF) is a noninvasive method to assess the level of AGEs in tissue, validated in CKD patients. Objective: The aim of this study is analyze AGEs measured by sAF levels (AGEs-sAF) and its relations with CVD and BMD parameters in HD patients...

The use of hadron beams, especially proton beams, in cancer radiotherapy has expanded rapidly in the past two decades. To fully realize the advantages of hadron therapy over traditional X-ray and gamma-ray therapy requires accurate positioning of the Bragg peak throughout the tumor being treated. Already a half century ago suggestions were made to use protons themselves to develop images of tumors and surrounding tissue, to be used for treatment planning. The recent global expansion of hadron therapy coupled with modern advances in computation and particle detection has led several collaborations around the world to develop prototype detector systems and associated reconstruction codes for proton computed tomography (pCT) as well as more simple proton radiography, with the ultimate intention to use such systems in clinical treatment planning and verification...

OBJECTIVES: Intrathecal drug administration using an implanted pump system is well established in intractable spasticity and pain. However, despite continuous advancements in manufacturing technology, adverse events related to the pump and catheter still occur. Most of them, such as migration, damage, disconnection and occlusion, are related to the spinal catheter. The aim of this overview is to update radiologists on how plain radiography of the implanted delivery system for intrathecal drug administration should be interpreted and to increase awareness for the need of urgent and timely multidisciplinary troubleshooting...
