»	Dose Reduction Strategy for Neuroradiology Computed Tomography Exams Successful
	At the University of California, San Francisco, systematic use of tube current dose modulation for computed tomography (CT) examinations most often performed in the neuroradiology section has led to significant reductions in radiation doses without sacrificing image quality.
»	Fluoroscopy Not Reliable for Detecting Causes of Stridor in Children
	Although airway fluoroscopy accurately diagnoses the cause of stridor in some children, its low sensitivity may necessitate further diagnostic evaluation of negative results, according to a report in the April issue of the Archives of Otolaryngology-Head and Neck Surgery.
»	Ultrasound Useful in Detecting Chest Wall Invasion by Lung Tumor
	Ultrasound examination is more sensitive than computed tomography (CT) scanning in assessing chest wall involvement in patients with lung cancer, according to findings published in the April issue of Chest.
»	Optic Nerve Ultrasound Detects Raised Intracranial Pressure in Head Injury
	Ultrasound assessment of the diameter of the optic nerve sheath can be used as a bedside test for early diagnosis of raised intracranial tension in head injury, researchers from India report.
»	Imaging Studies Won't Trump Clinical End Points But Can Aid Drug-Development Decisions
	They gathered to debate whether or not imaging studies could substitute for clinical end-point trials, but from the beginning both experts agreed that imaging modalities, be they computed tomography (CT), magnetic resonance imaging (MRI), intravascular ultrasound (IVUS), or carotid intima-media thickness (IMT) measurements, are simply not ready to be used as substitutes for hard clinical end points, such as death, myocardial infarction, or stroke.
