PURPOSE OF THE STUDY Accurate radiographic measurements are crucial in treating hallux valgus (HV). This three-dimensional deformity should not be evaluated from one joint on one plane. However, in practice, surgeons measure the deformity only on transverse dorsoplantar radiographs. We determined the amount of error associated with positioning the foot incorrectly on radiographs. MATERIAL AND METHODS To simulate incorrect positions of the foot in radiographic evaluation, we designed an angled device that can move in transverse and frontal plane...

Immune checkpoint inhibitors have shown significant antitumor activity and good tolerability in a number of cancer types and have entered the everyday oncological practice. This article briefly summarizes the mode of action of immune checkpoint inhibitors to provide a basis for the understanding of their clinical activity, radiological response patterns and adverse event profile.

OBJECTIVE: Evaluating preepiglottic space involvement in laryngeal cancer by CT may lead misinterpretation. We sought to understand the causes of misinterpretation in evaluating the preepiglottic space by CT and assessed the effects of misinterpretation in treatment plans of patients with laryngeal squamous cell carcinomas. METHODS: Specimen histopathology reports of 102 (99 male, 3 female) patients who underwent total or partial laryngectomy due to supraglottic and/or transglottic laryngeal carcinoma were reviewed...

BACKGROUND: Few data exist on malignant middle cerebral artery infarction (MMI) among patients with acute ischemic stroke (AIS) after endovascular treatment (ET). Numerous predictors of MMI evolution have been proposed, but a comprehensive research of patients undergoing ET has never been performed. Our purpose was to find a practical model to determine robust predictors of MMI in patients undergoing ET. METHODS: Patients from a prospective single-center database with AIS secondary to large intracranial vessel occlusion of the anterior circulation, treated with ET, were retrospectively analyzed...

BACKGROUND: Recently, a novel mobile intraoperative fan-beam CT (iFBCT) was introduced, allowing for real time navigation and immediate intraoperative evaluation of neural decompression in spine surgery. This study sought to investigate whether intraoperatively assessed neural decompression during minimally invasive spine surgery (MISS) has a predictive value for clinical and radiographic outcome. METHODS: A retrospective study of patients undergoing iCT-guided extreme lateral interbody fusion (XLIF) or transforaminal lumbar interbody fusion (TLIF) was conducted...

The poor prognosis of cholangiocarcinoma (CCA) is in part due to late diagnosis, which is currently achieved by a combination of clinical, radiological and histological approaches. Available biomarkers determined in serum and biopsy samples to assist in CCA diagnosis are not sufficiently sensitive and specific. Therefore, the identification of new biomarkers, preferably those obtained by minimally invasive methods, such as liquid biopsy, is important. The development of innovative technologies has permitted to identify a significant number of genetic, epigenetic, proteomic and metabolomic CCA features with potential clinical usefulness in early diagnosis, prognosis or prediction of treatment response...

AIM: To assess the evolution in management of children with parapneumonic effusion and empyema in a tertiary referral centre. METHOD: We conducted a retrospective case note review of paediatric patients with parapneumonic effusion, pleural effusion and pleural empyema between December 2006 and December 2015. Digital database searches were performed to identify demographic data, referring hospital, radiological and microbiological investigations. Length of stay and morbidity were analysed...

INTRODUCTION: Dimethyl fumurate (DMF) has been recently approved as a disease-modifying therapy for the treatment of multiple sclerosis (MS). Post-marketing studies are important to confirm what was established in clinical trials. OBJECTIVE: To evaluate effectiveness and safety of DMF and to measure the occurrence of lymphopenia in a cohort of MS patients in a clinical setting. METHODS: Using the national MS registry, we prospectively assessed relapsing MS patients who had been prescribed DMF for at least 6 months...

In the modern clinical practice of diagnostic radiology there is a growing demand for radiation dosimetry, it also being recognized that with increasing use of X-ray examinations additional population dose will result, accompanied by an additional albeit low potential for genetic consequences. At the doses typical of diagnostic radiology there is also a low statistical risk for cancer induction; in adhering to best practice, to be also implied is a low but non-negligible potential for deterministic sensitive organ responses, including in regard to the skin and eyes...

BACKGROUND: Malpositioned central venous access device (CVAD) tip locations can cause significant mechanical and chemical vessel-related injuries and complications if left in inappropriate positions.The aim of this study is to determine the use of a high-flow flush technique (HFFT) in successful correction of malpositioned catheters into the lower superior vena cava or cavoatrial junction and provide a cost comparison to interventional/fluoroscopic-based repositioning. METHODS: This is a Retrospective chart and radiographic review of all inserted CVADs found malpositioned between 1996-2014 in a multi-specialty 1000-bed tertiary trauma center in Sydney, Australia...

In clinical practice, the conventional radiography is still the radiologic method for the diagnosis of rheumatoid arthritis (RA). Moreover, it provides a quick overview of the symptomatic joints to narrow the differential diagnosis and to evaluate progression. RA is a polyarticular disease with bilateral and symmetric involvement of the peripheral joints, especially small joints, and less frequently, the cervical spine. The radiologic features are soft tissue swelling, periarticular osteoporosis, erosions, loss of joint space, and in advanced disease, osteolysis and typical subluxations or deformities, such as ulnar deviation...

The management of hydrocephalus can be challenging even in expert hands. Due to acute presentation, recurrence, accompanying complications, the need for urgent diagnosis; a robust management plan is an absolute necessity. We devised a novel time efficient surveillance strategy during emergency, and clinic follow up settings which has never been described in the literature. We searched all articles embracing management/surveillance protocol on pediatric hydrocephalus utilizing the terms "hydrocephalus follow up" or "surveillance protocol after hydrocephalus treatment"...

BACKGROUND: Low-field (LF) magnetic resonance imaging (MRI) is a technology that is widely used in resource-limited settings for clinical imaging. The images produced, even though of low resolution with noise and artefacts, provide valuable information and guidance for patient assessment and treatment. This study shows a spectrum of MRI artefacts that affect image quality during routine clinical neuroradiology practice using LF MRI in a Nigerian hospital and suggests ways to avoid them...

CONTEXT: The ability to preoperatively predict the outcome in cervical spondylotic myelopathy (CSM) helps in planning management and counseling the patient and family. AIMS: A simple prognostic scale, namely, the Madras Institute of Neurology Prognostic Scale (MINPS) for CSM has been proposed. SETTINGS AND DESIGN: Six well-known prognostic factors, namely, age, duration of symptoms, neurological disability (Nurick's grade), number of levels of compression, effective canal diameter, and intrinsic cord changes, have been taken into account...

As health care shifts toward patient-centered care, wait times have received increasing scrutiny as an important metric for patient satisfaction. Long queues form when radiology practices inefficiently service their customers, leading to customer dissatisfaction and a lower perception of value. This article describes a four-step framework for radiology practices to resolve problematic queues: (1) analyze factors contributing to queue formation; (2) improve processes to reduce service times; (3) reduce variability; (4) address the psychology of queues...

Objective Unclassifiable interstitial lung disease (ILD) is a common problem in clinical practice. These patients pose a distinct challenge with regard to appropriate evaluation and management. We investigated the clinical features and prognosis of unclassifiable ILD and compared its clinical profile with that of idiopathic pulmonary fibrosis (IPF) and idiopathic nonspecific interstitial pneumonia (NSIP). Methods Patients with IPF (n = 40), NSIP (n = 14), and unclassifiable ILD (n = 27) were selected from an ongoing database...
