Although the pathogenesis of the ‘reversed halo sign’ is not yet u...
BACKGROUND Computed tomography pulmonary angiography (CTPA) may improve the diagnostic capabilities of CT imaging for invasive mold disease, but its performance relative to other signs (ie, halo sign, hypodense sign, pleural effusion, reversed halo sign) is unknown. METHODS We prospectively compared the diagnostic performance of CTPA vs other CT imaging findings in 100 patients with hematolog...
PURPOSE The comparative cost-effectiveness of voriconazole and amphotericin B in the treatment of invasive pulmonary aspergillosis (IPA) was examined. METHODS A decision-tree model was constructed comparing 12-week treatment outcomes in a subset of patients enrolled in a clinical trial comparing initial treatment of IPA with amphotericin B versus voriconazole. Patients included those with IPA...
PURPOSE In patients with suspected giant cell arteritis (GCA), a search for the perivascular halo sign, a sophisticated color duplex ultrasound (CDU) finding, at experienced centers reliably identifies inflamed temporal arteries (TA). We tested whether TA compression in patients with GCA, a simple, largely operator-independent maneuver, elicits contrasting echogenicity between the diseased arte...
