Quantitative Computed Tomography
Computed Tomography (CT) is a wide-spread medical imaging modality. Traditional CT yields information on a patient’s anatomy in form of slice images or volume data. Hounsfield Units (HU) are used to quantify the imaged tissue properties. Due to the polychromatic nature of X-rays in CT, the HU values for a specific tissue depend on its density and composition but also on CT system parameters and...
متن کاملHigh resolution computed tomography in asthma.
OBJECTIVES High-resolution computed tomography (HRCT) can detect the structural abnormalities in asthma. This study attempts to correlate these abnormalities with clinical and pulmonary function test (PFT) data. METHODS Consecutive stable asthma patients attending Mubarak Al Kabeer Hospital, Kuwait, were subjected to HRCT during a six month period from July 2004 to December 2004, after initia...
متن کاملQuantitative computed tomography in children and adolescents
Methods for quantitative assessment of the skeleton are relevant to the understanding of growth and development during normal childhood and studying the effect of disease and therapy in children with chronic diseases. Dual energy x-ray absorptiometry (DXA) is currently the most widely available and utilised technique in adults and children. The strengths of DXA are: • The technology is widely a...
متن کاملQuantitative computed tomography measurements of emphysema for diagnosing asthma-chronic obstructive pulmonary disease overlap syndrome
BACKGROUND The diagnostic criteria of asthma-COPD overlap syndrome (ACOS) are controversial. Emphysema is characteristic of COPD and usually does not exist in typical asthma patients. Emphysema in patients with asthma suggests the coexistence of COPD. Quantitative computed tomography (CT) allows repeated evaluation of emphysema noninvasively. We investigated the value of quantitative CT measure...
متن کاملBone mineral density in steroid-dependent asthma assessed by peripheral quantitative computed tomography.
Chronic use of systemic glucocorticoids results in progressive bone loss and pathologic fractures. This study identified the predictive variables for bone loss and used peripheral quantitative computed tomography (pQCT) to measure changes in cortical and trabecular bone in patients receiving systemic glucocorticoid therapy of prednisone 15.4 g. Eighty-four asthmatic patients were included in th...
