Mobile radiography

PURPOSE: To optimise the radiation dose and image quality for chest radiography in the neonatal intensive care unit (NICU) by increasing the mean beam energy. METHODS: Two techniques for the acquisition of NICU AP chest X-ray images were compared for image quality and radiation dose. 73 images were acquired using a standard technique (56 kV, 3.2 mAs and no additional filtration) and 90 images with a new technique (62 kV, 2 mAs and 2 mm Al filtration). The entrance surface air kerma (ESAK) was measured using a phantom and compared between the techniques and against established diagnostic reference levels (DRL)...

INTRODUCTION: Mobile devices and software are now available with sufficient computing power, speed and complexity to allow for real-time interpretation of radiology exams. In this paper, we perform a multivariable user study that investigates concordance of image-based diagnoses provided using mobile devices on the one hand and conventional workstations on the other hand. METHODS: We performed a between-subjects task-analysis using CT, MRI and radiography datasets...

BACKGROUND CONTEXT: Patients with infective spondylodiscitis who failed conservative treatment are generally indicated for open surgery. However, some patients are poor candidates for standard surgery, hence the need to evaluate less invasive approaches. Good outcomes were previously reported for percutaneous suction aspiration and drainage (PSAD) in the treatment of infective spondylodiscitis resistant to conservative therapy. We recently extended the surgical approach of PSAD to allow drainage of paravertebral or epidural abscesses in patients with progressive infective spondylodiscitis...

BACKGROUND: The anterior drawer test is traditionally used to assess ankle instability, but we believe that there is room for a small but effective improvement by adding digital palpation of the talus. We aimed to determine the accuracy of anterolateral talar palpation (ATP) in the diagnosis of ankle instability by comparing it with the traditional anterior drawer test. METHODS: Fourteen symptomatic and 10 asymptomatic patients were examined for excessive mobility through comparison of both ankles by two blinded orthopedic surgeons, each one using one of the above-mentioned tests...

OBJECTIVE: The purpose of this study was to use patient data gathered by a hospital information system (HIS) to improve the safe performance of bedside radiography. METHOD: Hierarchical cluster analysis was used to investigate the factors of hospitalised patients who had undergone radiography in the X-ray room or at the bedside. Logistic regression analysis was then performed to quantify patient factors and calculate the probability of undergoing general radiography or bedside radiography...

Psoriatic arthritis (PsA) is a heterogeneous chronic inflammatory arthritis characterised by a range of musculoskeletal conditions including enthesitis, dactylitis and synovitis as well as skin and nail manifestations. The foot is a complex mixture of tissues, all of which can be involved in this disease and is frequently the presenting feature. Areas covered: In this under-researched area, articles were reviewed from the authors' publications as well as from other known authors. This review will discuss how PsA affects the foot and ankle with a particular focus on synovitis, tenosynovitis, enthesitis, dactylitis, bone erosion and psoriatic skin and nail disease...

In this review, we aimed to depict the clinical, radiological, and genetic features of cleidocranial dysplasia (CCD) and to suggest management guidelines, based on our experience of 8 cases, with an emphasis given to dental complications.The most common craniofacial features of CCD that stand out are a patency of the anterior fontanelle, an inverted pear-shaped calvaria, a hypertelorism, a general midface retrusion, and a mandible prognathism, associated with an excessive mobility of the shoulders, a short stature, and teeth abnormalities such as supernumerary teeth and failure of eruption, in particular...

Introduction: Odontoideum bone or the mobile odontoid process is one of the rarest malformations of the cervico-occipital hinge. It exposes to the atlo-axial instability and to the risk of bulbo-medullary compression threatening then the vital and functional prognosis. We report the case of a 16-year-old patient who was the victim of a raod accident resulting in acervical spine injury. Radiological investigation found an odontoideum bone malformation associated with C1C2 dislocation. Case Report: A 16-year-old patient with no medical history had a road accident...

OBJECTIVE: The objective of this study is to investigate the eruption pattern and root resorption of the bovine anterior dentition in relation to growth-related parameters based on dental maturity. METHODS: A cross-sectional study was conducted on 110 bovine anterior mandibles by using standard radiography, cone-beam computed tomography (CBCT), and actual measurements. We determined the relationships between the stages of dental maturity by using a modification of Demirjian's method and various growth-related parameters, such as the activity of the root-resorbing tissue and mobility of the deciduous teeth...

Chest wall ultrasound has been awarded little interest in the literature, with chest wall anatomy described only in limited extent. The objective of this study has been to discuss the methodology of chest wall ultrasound and the sonographic anatomy of the region to facilitate professional evaluation of this complex structure. The primarily used transducer is a 7-12 MHz linear one. A 3-5 MHz convex (curvilinear) transducer may also be helpful, especially in obese and very muscular patients. Doppler and panoramic imaging options are essential...

The US National Registry of Clinical Trials (ClinicalTrials.gov) and the World Health Organisation (WHO) International Clinical Trials Registry Platform were searched for ongoing trials. There were no restrictions regarding language and publication date. The authors hand-searched the reference lists of the studies retrieved and key journals in the field of endodontics...

OBJECTIVES: To compare image quality, visibility of anatomic landmarks, tubes and lines, and other clinically significant findings on portable (bedside) chest radiographs acquired with wireless direct radiography (DRw) and computed radiography (CR). METHODS: In a prospective IRB-approved and HIPAA-compliant study, portable DRw (DRX-1C mobile retrofit portable wireless direct radiography, CareStream Inc., Rochester, NY) and portable CR (AGFA CR (DXG) version; NIM2103, AGFA Healthcare, Ridgefield Park, NJ) images of the chest were acquired within 24-hours in 80 patients in the intensive care unit (ICU)...

RATIONALE: Pelvic malunion is a rare complication and is technically challenging to correct owing to the complex three-dimensional (3D) geometry of the pelvic girdle. Hence, precise preoperative planning is required to ensure appropriate correction. Reconstructive surgery is generally a 2- or 3-stage procedure, with transiliac osteotomy serving as an alternative to address limb length discrepancy. PATIENT CONCERNS: A 38-year-old female patient with a Mears type IV pelvic malunion with previous failed reconstructive surgery was admitted to our department due to progressive immobilization, increasing pain especially at the posterior pelvic arch and a leg length discrepancy...

INTRODUCTION: The management of volar plate avulsion fractures in the context of a stable joint and a bony fragment of less than 30% has traditionally been conservative. This study was performed to assess volar plate healing with high-resolution ultrasound in order to provide early full mobilization. MATERIAL AND METHODS: Between January 2012 and December 2013, 78 patients with volar plate injuries of the proximal interphalangeal (PIP) joints (42 distortions and 36 dislocations) were treated conservatively in our department for volar plate avulsion fracture associated with stable joint and bony fragment inferior to 30% of the intra-articular surface assessed both by radiography and ultrasound...

We report here the case of a 3-year-old patient, who presented a left limp and a total refusal of walking, without any traumatism. Clinical examination revealed a significant pain in the left leg with a limit to the limiting mobilization. Acute phase reactants were slightly elevated. Based on the hip ultrasound, acute transient synovitis of the hip was diagnosed. Following persistent complaints, a hip plain radiography was performed, showing a discreet reshuffle at the right ischiopubic branch. The MRI of the hip revealed a discrete T2 high intensity centered on the right ischiopubic synchondrosis (IPS), corresponding to a Van Neck-Odelberg osteochondrosis...

Injuries occurring in the remote environment present particular challenges to healthcare professionals, and decisions need to be carefully made on an individual basis. This report describes the successful management of a patella fracture sustained on the Subantarctic island of South Georgia. A 36-year-old boating officer presented to the island surgery after sustaining an isolated closed injury to his left knee. On physical examination there was a large effusion palpable within the joint, and on subsequent radiography an undisplaced transverse fracture of the patella was apparent...

Chest wall hemangiomas are rare tumors that may originate within the soft tissue or from the ribs. Intramuscular hemangioma is infrequent, representing less than 1 % of all hemangiomas, and the localization in the chest wall is even less frequent. They are typically cutaneous in location, large, and poorly circumscribed and can be locally destructive. We present a case of a 34-year-old lady presented with firm lump 3 × 3 cm in left upper and inner quadrant of left breast well defined borders, non-pulsatile and restricted mobility...

Commercially available prostheses do not meet patients' expectations regarding dimensions, shape and aesthetic reasons. This paper presents the design of an anthropomorphic and anthropometric prosthesis based on dimensions and shape extracted from a digitized radiograph of the healthy hand of the patient. The mobility of the hand is guaranteed by making a design of phalanges, joints, ligaments and tendons, as closest as possible to a real hand. The kinematic model is presented and validated. A proposal of the actuation system is also described...

BACKGROUND/PURPOSE: Radial head replacement is frequently used in treatment of radial head fractures or sequela. Impossibility to restore a correct anatomy, acute elbow traumatic instability and failure of osteosynthesis hardware are the most common indications. The authors describe their case studies and results on the implantation of various radial head prostheses. MATERIALS: Between June 2005 and June 2016, 28 radial head prostheses were implanted in the same number of patients with an average follow-up of 49 months (6-104)...

BACKGROUND: Severe separation of the pubic symphysis is a rare delivery complication. Facing this pathology, we decided to study a new elastic band device. METHOD: To evaluate the elastic band device, clinical (pain-rated) and imaging (magnetic resonance imaging and radiography) evaluations with and without the device were performed. The elastic band device is a European Conformity-certified medical device, which is made of neoprene straps, that reduces the mobility of the pelvis and the use of the internal rotator muscles...
