The incidence of human immunodeficiency virus (HIV) infection has gradually increased in recent years.HIV mainly destroys the body's immune system,leading to decreased body resistance and thus the development of a variety of opportunistic infections and neoplastic diseases,especially in the digestive system. However,the clinical manifestations,laboratory findings,and physical examination results of these conditions are not specific. Imaging examinations can determine the presence of infection and tumor lesions and the disease scope;furthermore,they are useful tools for biopsy and follow-up evaluation...

Daniel Yiang Wu, Eddy Kwok Fai Lam
One of the main objectives of hallux valgus surgery is correction of the metatarsus primus varus deformity by osteotomy, arthrodesis, or soft tissue correction. The syndesmosis procedure uses intermetatarsal cerclage sutures to realign the first metatarsal and also induces a syndesmotic bonding between the first and second metatarsals to prevent metatarsus primus varus deformity recurrence. The purpose of the present study was to demonstrate radiologic evidence of the effectiveness of the syndesmosis concept and to identify the incidence and nature of deformity recurrence...

INTRODUCTION: The anatomy of the cochlea forms the basis for a successful cochlear implantation. Cochlear duct length (CDL) is defined as the length of the scala media as measured from the middle of the round window to helicotrema. Preoperative measurement of CDL is particularly important when precise intracochlear electrode array placement is desired. It can be done both histologically and radiologically. Preoperative high-resolution computed tomography (HRCT) scan which forms an integral part of cochlear implant workup is a useful tool to calculate CDL using 3D reconstructions...

BACKGROUND: Intracranial (cavernous malformations) CMs are usually located at the cerebral parenchyma, dural-based CMs outside the middle fossa are rarely reported. To our knowledge, dural-based CMs located at the cerebral convexity are even rarer that only two pediatric cases were ever reported. In this report, we present two extremely rare cases of dural-based CMs at the cerebral convexity in pediatric patients. The clinical course, radiological and pathological features, treatment, and follow-up are described...

INTRODUCTION: In addition to diffuse brain oedema, diabetic ketoacidosis (DKA) can lead to ischaemic or haemorrhagic stroke, extrapontine myelinolysis, and sinovenous thrombosis. However, posterior reversible encephalopathy syndrome (PRES) and spinal cord oedema are rarely reported in patients with DKA. METHODS: We present a case of a 17-year-old-girl who developed headache, blurred vision, and paraplegia after her DKA was controlled. Sequential magnetic resonance (MR) scans of the brain and spinal cord were performed...

Case of cerebrofacial arteriovenous metameric syndrome (CAMS) in a 9-year-old boy is described with arteriovenous malformation simultaneously involving the brain and face, with characteristic CAMS type 1 and 2 involvement. This patient demonstrates the wide spectrum of clinical manifestations of CAMS, and in this particular case, the patient exhibits features of hypopituitarism-an association that was not previously described in the literature to our knowledge. Awareness of the underlying embryological abnormality and recognition of resultant clinical and radiological presentations are paramount for diagnosis and treatment...

To date, the methods developed for automated extraction of information from radiology reports are mainly rule-based or dictionary-based, and, therefore, require substantial manual effort to build these systems. Recent efforts to develop automated systems for entity detection have been undertaken, but little work has been done to automatically extract relations and their associated named entities in narrative radiology reports that have comparable accuracy to rule-based methods. Our goal is to extract relations in a unsupervised way from radiology reports without specifying prior domain knowledge...

Describing complex mammography examination processes is important for improving the quality of mammograms. It is often difficult for experienced radiologic technologists to explain the process because their techniques depend on their experience and intuition. In our previous study, we analyzed the process using a new bottom-up hierarchical task analysis and identified key components of the process. Leveraging the results of the previous study, the purpose of this study was to construct a mammographic examination process ontology to formally describe the relationships between the process and image evaluation criteria to improve the quality of mammograms...

Martina Vašáková
Idiopathic pulmonary fibrosis (IPF) is a severe pulmonary disease characterized by fibrotisation of lung tissue based on pathological healing of alveolar lesions. The disease is initiated in individuals of middle and older age who have a genetical disposition to fibroproliferation. Clinical presentation is not uniform. The patients can have a rapidly progressive disease, eventually severe acute exacerbations, however some of them can have relatively benign course of the disease. Problems in diagnosis are usually caused by atypical radiologic findings and no or nondiagnostic lung biopsy...

BACKGROUND: Osseous dysplasia (OD) is the most common fibro-osseous lesion of the jaw affecting the periapical region. Early stages of OD can resemble periapical radiolucencies, thus mimicking the radiological aspects of an endodontic pathology. Such radiolucent lesions affecting previously decayed or treated teeth are even more complex to interpret. CASE PRESENTATION: The aim of this paper is to report a case-series of representative clinical situations describing the radiological features and illustrating the diagnostic workup of patients with florid osseous dysplasia (FOD)...

INTRODUCTION: Since the advent of prostate-specific antigen (PSA)-based testing, transrectal ultrasound (TRUS)-guided prostate biopsy has become a standard part of the diagnostic pathway for prostate cancer (PCa). Rectal bleeding is one of the common side effects of this transrectal route. While rectal bleeding is usually mild and self-limiting, it can be life-threatening. In this article, we examine rectal bleeding post TRUS-guided prostate biopsy and explore the literature to evaluate techniques and strategies aimed at preventing and managing this common and important complication...

Abnormalities of the posterior arch of vertebras are rare conditions that may incidentally be found on neck radiographs. The diagnosis of such abnormalities are of high level of importance because of resultant neurological defects. In this study, we report a 10-year-old boy presented with intermittent paresthesia in lower extremities, mild neck pain and episodes of drop attacks following neck flexion. Radiological investigations depicted a complete absence of the posterior element of C1, C2 and C3 along with bilateral absence of C4 pedicles...

The rapid pace of technologic advancement and increasing expectations for patient- and family-friendly environments make it common for radiology leaders to be involved in imaging remodel and construction projects. Most radiologists and business directors lack formal training in architectural and construction processes but are expected to play significant and often leading roles in all phases of an imaging construction project. Avoidable mistakes can result in significant increased costs and scheduling delays; knowledgeable participation and communication can result in a final product that enhances staff workflow and morale and improves patient care and experience...

The routine dissection of a male body revealed multiple anatomical variations of the celiac trunk and hepatic artery vascularization. The origin of the celiac trunk was on the left side of the abdominal aorta, next to the T12-L1 intervertebral disk. The celiac trunk gave off five branches: the left inferior phrenic artery, the left gastric artery, the accessory right hepatic artery, the common hepatic artery and the splenic artery (the last two arteries had a common origin in a hepatosplenic trunk). A right branch detached off the left gastric artery and anastomosed with the hepatic artery proper...
