PURPOSE We reviewed the clinical outcome for patients who underwent decompression of malignant ureteral obstruction by analyzing potential prognostic factors, technical success, complication rates and days spent in hospital. MATERIALS AND METHODS Retrospective analysis of 102 patients who underwent decompression for malignant ureteral obstruction from(More)
BACKGROUND AND PURPOSE This prospective study sought to determine how the use of combined PET/CT for radiotherapy treatment planning of oesophageal cancer would alter the delineation of tumour volumes compared to CT alone if PET/CT is assumed to more accurately represent true disease extent. PATIENTS AND METHODS All patients underwent FDG-PET/CT scanning(More)
OBJECTIVE To determine whether onset seizures after subarachnoid hemorrhage (SAH) carry independent prognostic information and to investigate the risk factors for late seizures after SAH. BACKGROUND Modern management of SAH, including early operation, has substantially reduced mortality. No study has adequately assessed the importance of onset seizures in(More)
Reversible posterior leukoencephalopathy syndrome (RPLS) is an uncommon but distinctive clinicoradiological entity comprising of headache, seizures, visual disturbance, and altered mental function, in association with posterior cerebral white matter edema. With appropriate management, RPLS is reversible in the majority of cases. Previous reported(More)
This article proposes a practical method for measuring staff radiologist workloads (clinical productivity) in teaching hospital departments of radiology in Australia. It reviews the Australian background to this, including the Royal Australian and New Zealand College of Radiologists (RANZCR) Education Board accreditation guidelines and the development of(More)
The aim was to establish a reference range of measurements for all major Circle of Willis (COW) arteries for an Australian population of patients presenting for brain magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA) that is typical of a tertiary referral hospital; and to report the prevalence and disease associations of COW variants(More)
The work of diagnostic radiology consists of the complete detection of all abnormalities in an imaging examination and their accurate diagnosis. Errors in diagnostic radiology comprise perceptual errors, which are a failure of detection, and interpretation errors, which are errors of diagnosis. Perceptual errors are subject to rules of human perception and(More)
UNLABELLED (18)F-FDG PET qualitative tumor response assessment or tumor-to-background ratios compare targets against blood-pool or liver activity; standardized uptake value (SUV) semiquantitation has artifacts and is validated by a stable normal-tissue baseline. The aim of this study was to document the normal intrapatient range of scan-to-scan variation in(More)
AIM The aim of this study was to evaluate the accuracy and clinical impact of single-reader breast MR (BMR) used as a clinical 'problem solving' tool. METHODS Observational, retrospective, ethics approved data collection for all BMR were from May 2006 to February 2009 (n=143). Cases were stratified into groups according to indication for referral. MR data(More)
AIM Knowledge of the normal range of periprosthetic osteoblastic activity around total hip arthroplasties is required for rational diagnosis of complications. The aim of this study was to establish such a normal range for single-photon emission computed tomography (SPECT). Clinical utility of such a range is confident differentiation of normal from abnormal(More)
