BACKGROUND There is a strong positive association between Framingham Risk Scores (FRS) in a population and incidence of hard coronary heart disease (hCHD) events. Under current Adult Treatment Panel III guidelines, individuals with FRS that indicate ≥20% 10-year risk of hCHD are recommended to receive intensive medical risk factor modification. We sought to(More)
OBJECTIVE To assess accurate skeletal age (SA) in clinical and medico-legal decisions using the Greulich-Pyle (GP) atlas and to see its applicability across diverse populations in Karachi. METHODS Hand-Wrist radiographs obtained at our institution from January 2005 to March 2008, for an indication of trauma, in subjects with chronological age (CA) up to(More)
Technology assessment should touch upon four areas; utility, target population, cost and alternatives. Hybrid Positron Emission Tomography/Computed Tomography (PET/CT) is a promising modality for oncologic imaging. However, reservations about its accessibility and affordability prevail. Magnetic Resonance Imaging (MRI) is an alternative with certain key(More)
OBJECTIVE 60-80% of heart attacks or coronary-related deaths occur in individuals identified as non-high-risk per the conventional risk assessment algorithms. Abnormal ankle-brachial index (ABI), plasma fibrinogen and plasma C-reactive protein (CRP) have been shown to be associated with a higher risk of cardiovascular disease (CVD). However, comparable data(More)
PURPOSE To determine the prevalence of an abnormal ankle-brachial index (ABI) among subjects not considered to be at high risk for cardiovascular disease (CVD) based on the Framingham Risk Score (FRS). MATERIALS AND METHODS Data from the Population-Based Examinations to Determine Ankle-brachiaL index (PEDAL) Study (2007-2009), a cross-sectional study at(More)
INTRODUCTION Mesenteric panniculitis is a rare pathology of unknown etiology characterized by inflammation and fibrosis in the mesentery. Its protean clinical and radiological manifestations make it a diagnostic challenge. There is no established treatment available for its management. The clinical outcome is inconsistent, with the prognosis ranging from(More)
OBJECTIVES To study the changing pattern in the use of intravenous urogram (IVU) and non-contrast enhanced CT (CTKUB) for evaluation of flank pain at a single centre. METHODS All patients who underwent either an IVU or CTKUB at a single, tertiary care center from January 2002 to December 2007 were retrospectively identified from the radiology database.(More)
OBJECTIVE The recent escalation in lower extremity revascularization procedures suggests a concomitant increase in peripheral arterial disease (PAD) screening. We hypothesized that self-referring physicians would show the greatest growth in noninvasive physiologic testing for PAD and similar trends for revascularization procedures. We compared utilization(More)
PURPOSE To report the results of a standard gamble-type survey conducted to explore patients' heuristics in regard to therapy for peripheral arterial disease (PAD). MATERIALS AND METHODS Patients presenting to a vascular and interventional radiology practice because of suspected PAD were asked to indicate their threshold for risk of amputation during a(More)
OBJECTIVE To assess communication and interpersonal skills (CIS) of radiology residents through faculty and standardised patients (SP). METHODS In this day-long objective structured clinical examination (OSCE) in January 2009, 42 radiology residents took part at six stations in Karachi, each with a standardised patient and a faculty evaluator.
