Anesthesia providers are frequently exposed to radiation during routine patient care in the operating room and remote anesthetizing locations. Eighty-two percent of anesthesiology residents (n = 57 responders) at our institution had a "high" or "very high" concern about the level of ionizing radiation exposure, and 94% indicated interest in educational materials about radiation safety. This article highlights key learning points related to basic physical principles, effects of ionizing radiation, radiation exposure measurement, occupational dose limits, considerations during pregnancy, sources of exposure, factors affecting occupational exposure such as positioning and shielding, and monitoring...

Diplopodia, being a rare congenital disorder, is infrequently discussed in published texts. Most reported cases have accounted the involvement of duplicated preaxial digits with other associated organ system and physical deformities. Here, we present an unusual case of isolated diplopodia involving postaxial toes in a child with no other organ and physical abnormalities. Radiological studies revealed a set of 10-digit-duplicated foot over the lateral aspect of the native foot, complete with phalanges and its corresponding metatarsals as well as tarsals, supplied by an anomalous posterior branch of the popliteal artery...

BACKGROUND: Several models have been developed for prediction of contrast-induced nephropathy (CIN); however, they only contain patients receiving intra-arterial contrast media for coronary angiographic procedures, which represent a small proportion of all contrast procedures. In addition, most of them evaluate radiological interventional procedure-related variables. So it is necessary for us to develop a model for prediction of CIN before radiological procedures among patients administered contrast media...

: 121 Background: Wait times for critical interventional radiology (IR) procedures have long been reported as barriers to access for cancer patients. Wait times have been difficult to measure in the province of Ontario as no mechanisms exist to capture IR data. Three individual programs at Cancer Care Ontario (CCO) began collection of CT-guided biopsies wait time data, with nuances dependent on program area of focus. The Cancer Imaging Program collects appointment availability for lung biopsies through a monthly email survey...

A Klingenstein, C Hintschich
Exophthalmos is a common and important symptom in orbital consultation. It can be either uni- or bilateral. A wide spectrum of benign and malignant diseases has to be considered and evaluated for differential diagnosis, in order to maintain complete ocular function and to lead the patient to adequate therapy. Exophthalmos can be accompanied by variable symptoms, ranging from neurogenic or myogenic to corneal alterations. Symptoms at presentation depend on the underlying disease and may manifest systemically...

BACKGROUND: Angiomatoid fibrous histiocytoma (AFH) is a rare soft tissue tumor of intermediate biologic potential. Because of its rarity and nonspecific radiological and diverse pathological findings, AFH is often clinically misdiagnosed. However, few clinical reports have described this tumor. As reported herein, we analyzed the clinical and radiological features and clinical outcomes of AFH. METHODS: We retrospectively reviewed the medical records of seven cases histopathologically diagnosed as AFH...

Background Femoroacetabular impingement (FAI) describes a painful, abnormal (bony) contact between the femoral neck and acetabulum, which, if left untreated, contributes to early osteoarthritis (OA) of the hip. Despite its flat learning curve and long operation times, hip arthroscopy has been used increasingly often in recent years in the surgery of femoroacetabular impingement. The mini-open technique (MOT) offers a possible alternative that addresses the abnormal morphological prominence and allows minimally invasive clearance of hip motion...

We built a natural language processing (NLP) method to automatically extract clinical findings in radiology reports and characterize their level of change and significance according to a radiology-specific information model. We utilized a combination of machine learning and rule-based approaches for this purpose. Our method is unique in capturing different features and levels of abstractions at surface, entity, and discourse levels in text analysis. This combination has enabled us to recognize the underlying semantics of radiology report narratives for this task...

: CT ventilation imaging is an exciting functional imaging modality that combines four-dimensional computed tomography (4DCT) and deformable image registration (DIR) to provide exquisite ventilation maps of the lung. CT ventilation imaging can be used for: (1) Functional avoidance in thoracic radiation therapy, (2) Imaging longitudinal changes in regional lung function for treatment assessment and adaptation, (3) Image-assisted diagnosis of non-oncologic respiratory diseases. CT ventilation imaging uses CT, a predominantly anatomic imaging modality, and through imaging processing creates functional images...
