Acute diaphragmatic abnormalities encompass a broad variety of relatively uncommon and underdiagnosed pathologic conditions, which can be subdivided into nontraumatic and traumatic entities. Nontraumatic abnormalities range from congenital hernia to spontaneous rupture, endometriosis-related disease, infection, paralysis, eventration, and thoracoab...
Gastropulmonary fistula represents a late complication of sleeve gastrectomy and, if untreated, has high morbidity and mortality. We present a case report of a 29-year-old female who developed a gastropulmonary fistula 3 years after a sleeve gastrectomy. Dual energy CT of the chest and upper abdomen demonstrated a cavitary left lower lobe lesion as...
“Radiologists are key members of the multidisciplinary team and play an integral role in the diagnosis and management of patients pre- and post-emergency surgery. Through a timely and accurate diagnosis of potentially life-threatening injuries, radiological services facilitate the clinical decision-making process for appropriate surgical, intervent...
Purpose:
Prospective radiology fellows utilize the internet to apply for radiology fellowship programs. The aim of this study was to analyze the online content of Canadian radiology fellowship websites.
Methods:
The content of all active Canadian radiology fellowship websites were evaluated using 30 criteria in the following domains: application...
PurposePancreatic injury is associated with significant morbidity and mortality. Pancreatic lacerations can be challenging to identify as the pancreas is not scanned at peak enhancement in most trauma CT protocols. This study qualitatively and quantitively assessed pancreatic lacerations with virtual monoenergetic dual-energy CT (DE CT) to establis...
Although acute ischemic stroke remains one of the most common causes of death and disability worldwide, it is a potentially treatable condition if appropriately managed in a timely manner. The goals of acute stroke imaging include establishing a diagnosis as fast as possible with (1) accurate infarct quantification, (2) intracranial and cervical va...
To describe a novel time-resolved magnetic resonance angiography (TR-MRA) postprocessing technique using the time-resolved angiography with interleaved stochastic trajectories (TWIST) method to evaluate the pulmonary veins and left atrium in adults with congenital heart disease undergoing cardiac MRI. Institutional ethics committee approved the stu...
Background
The increased strength and conditioning of elite athletes has led to greater potential for high impact injuries. With increasing concerns for player welfare, the decision to return to play after sustaining an on-field injury is complex.
Aim
Review of a 5-year experience of a pitch side radiology unit (PSRU) at a large international spor...
Objectives
Computed tomography cervico-cerebral angiography (CTCCA) plays a pivotal role in the evaluation of acute stroke. Currently no evidence justifies the inclusion of the upper chest in the CTCCA field of view. The aim of this study was to assess the prevalence and clinical significance of vascular findings identified on CTCCA in the head, ne...
Early and accurate diagnosis of mesenteric ischemia remains challenging due to the broad spectrum of clinical symptoms and radiological findings. Prompt diagnosis reduces and may allow for interventional radiology treatment opportunities. Computed tomography (CT) is now the first-line imaging tool for investigation of suspected acute or chronic mes...
Background:
Intra-abdominal hypertension is a common complication in critically ill patients. Recently the Abdominal Compartment Society (WSACS) developed a medical management algorithm with a stepwise approach according to the evolution of the intra-abdominal pressure and aiming to keep IAP ≤ 15 mm Hg. With the increased use of ultrasound as a be...
Objective:
To describe and evaluate a novel technical development to improve detection of intracranial vessel occlusions using multiphase CT angiography (MPCTA).
Materials and methods:
The institutional ethics committee approved the study. Fifty patients (30 consecutive distal (M2 or smaller) anterior circulation occlusions, ten M1 occlusions, t...
Background and purpose:
Multiphase CTA, a technique to dynamically assess the vasculature in acute ischemic stroke, was primarily developed to evaluate collateral filling. We have observed that it is also useful in identifying distal anterior circulation occlusions due to delayed anterior circulation opacification on multiphase CTA, an observation...
An understanding of the new generation of MS drugs in conjunction with the key role MR imaging plays in the detection of disease progression, opportunistic infections, and drug-related adverse effects is of vital importance to the neuroradiologist. Part 1 of this review outlined the current treatment options available for MS and examined the mechan...
Imaging for the diagnosis and follow-up of patients with suspected or confirmed multiple sclerosis is a common scenario for many general radiologists and subspecialty neuroradiologists. The field of MS therapeutics has rapidly evolved with multiple new agents now being used in routine clinical practice. To provide an informed opinion in discussions...
EuroSafe Imaging 2017 / ESI-0037 The role of consolidation and leadership by the national cancer screening program in symptomatic and asymptomatic radiological breast imaging optimisation and breast dose reduction in Ireland
Objective: The “delayed vessel sign” refers to the presence of relative unilateral delayed enhancement of a vessel or vessels in the anterior circulation on delayed phases of a multiphase CTA (MPCTA) distal to the point of vessel occlusion. We aimed to determine if educating radiologists on the “delayed vessel sign” would improve sensitivity, confi...
PurposeTransradial pneumatic compression devices can be used to achieve haemostasis following radial artery puncture. This article describes a novel technique for acquiring haemostasis of arterio-venous haemodialysis fistula access sites without the need for suture placement using one such compression device. Materials and MethodsA retrospective re...
Background: Neoadjuvant chemoradiotherpy (CRT) has become standard in the treatment of rectal cancer patients with stage 3 disease. This approach has shown to reduce both local recurrence rates and increase the rate of sphincter preservation procedures.Up to 20% of patients 6 weeks post neoadjuvant CRT have a complete histological response (pCR). P...
Therapeutic radiotherapy rarely causes sarcoma, and this occurs years after completion of the intended treatment. In treating breast carcinoma, careful planning in the application of modern radiotherapeutic techniques usually can shield the heart and pericardium.
We report a rare case of angiosarcoma of the pericardium, which presented in a 41-year...
Groin pain is a common symptom in athletes, particularly in sports requiring sudden changes in speed and direction and those involving kicking. Despite a high prevalence of groin pain in this patient cohort, the diagnosis and management of the underlying pathological processes remains a challenge for surgeons and radiologists alike.
The aim of this...
Intra-abdominal hypertension (IAH) is common in critically ill patients. Diagnosis is based on measurement of intra-abdominal pressure, most commonly via the bladder. Modern imaging techniques with plain radiographs, computed tomography and magnetic resonance can help establish the diagnosis and also guide treatment. In 2013 the Abdominal Compartme...
A 51-year-old man presented with a prodrome of arthralgia, intermittent oral ulceration, and raised inflammatory markers. He was extensively investigated; however, no firm diagnosis could be established, and he remained under regular surveillance by rheumatology and infectious disease services. After 12 months, he presented with painful ear swellin...
