AIM To investigate the effects of a test bolus protocol contrast medium administration on diagnostic image quality in computed tomography pulmonary angiography (CTPA). MATERIALS AND METHODS Fifty patients referred for exclusion of pulmonary embolism underwent CTPA using a test bolus protocol CTPA at 120 kVp and were compared with 50 patients undergoing(More)
OBJECTIVE We report a novel, computed tomography guided treatment for autophony associated with a patulous eustachian tube. METHODS Case report and literature review of the management of patulous eustachian tube. RESULTS A 36-year-old woman presented with disabling autophony. Otoscopic examination revealed a poorly mobile right tympanic membrane. High(More)
OBJECTIVE Myocardial intracellular/extracellular structure and aortic function were assessed among hypertensive left ventricular (LV) phenotypes using cardiovascular magnetic resonance (CMR). METHODS An observational study from consecutive tertiary hypertension clinic patients referred for CMR (1.5 T) was performed. Four LV phenotypes were defined: (1)(More)
AIMS We sought to determine the prevalence of asymmetric hypertensive heart disease (HHD) overlapping morphologically with hypertrophic cardiomyopathy (HCM) and to determine predictors of this pattern of hypertensive remodelling. METHODS AND RESULTS One hundred and fifty hypertensive patients underwent 1.5 T cardiovascular magnetic resonance imaging.(More)
Retroclival haematomas are rare entity and they are mostly caused by trauma. There has been only one case published to have a retroclival haematoma following pituitary apoplexy. We present a patient diagnosed with pituitary apoplexy who was found to have acute subdural retroclival haematoma on the MRI.
The purpose of this study was to determine whether performing the test bolus (TB) of computed tomography coronary angiography (CTCA) and computed tomography pulmonary angiography (CTPA) at 80 kVp reduces dose without compromising diagnostic quality. An 80 kVp TB protocol for CTCA and CTPA was retrospectively compared to standard TB protocol (non-obese: 100(More)
Acute coronary syndrome (ACS) still remains one of the leading causes of mortality and morbidity worldwide. Seven to fifteen percent of patients presenting with ACS have unobstructed coronary artery disease (CAD) on urgent angi-ography. Patients with ACS and unobstructed coronary arteries represent a clinical dilemma and their diagnosis and management is(More)
Fungi cause a wide spectrum of fungal diseases of the upper and lower airways. There are three main phyla involved in allergic fungal disease: (1) Ascomycota (2) Basidiomycota (3) Zygomycota. Allergic fungal rhinosinusitis (AFRS) causes chronic rhinosinusitis symptoms and is caused predominantly by Aspergillus fumigatus in India and Bipolaris in the United(More)
Tilz RR et al. Impact of pulmonary vein anatomy assessed by cardiac magnetic resonance imaging on endo-scopic pulmonary vein isolation in consecutive patients. Impact of pharmacological autonomic blockade on complex fractionated atrial electrograms. A et al. Prospective assessment of late conduction recurrence across radiofrequency lesions producing(More)
Increased oxygen uptake and utilisation during exercise depend on adequate adaptations of systemic and pulmonary vasculature. Recent advances in magnetic resonance imaging techniques allow for direct quantification of aortic and pulmonary blood flow using phase-contrast magnetic resonance angiography (PCMRA). This pilot study tested quantification of aortic(More)
