Impact of the IWG/Dubois Criteria for Alzheimer’s Disease in Imaging Studies
The NINCDS-ADRA concept of AD diagnosis (1984) The IWG concept of AD diagnosis (2007) The diagnosis of AD cannot be certified clinically and needs a postmortem confirmation to be ascertained…
An Investigation of Statistical Power of [15O]-H2O PET Perfusion Imaging: The Influence of Delay and Time Interval
Fig. 6.1 The same contrast analysis, motor task versus control task, resulted in markedly different activation patterns depending on the time interval that was analyzed (indicated by white bars). Small…
The Interstitial Pneumonias
The interstitial pneumonias (IPs), or idiopathic interstitial pneumonias (IIPs), are a heterogeneous group of diffuse lung diseases characterized by varying degrees of lung inflammation and fibrosis. They are best thought…
Airways Diseases
Airways disease may have a variety of causes, including inhalation of organic or inorganic materials, systemic diseases, infections, tumors, and congenital defects. Airways diseases are broadly categorized by the size…
Reticular Opacities
Reticular opacities seen on HRCT in patients with diffuse lung disease can indicate lung infiltration with interstitial thickening or fibrosis. Three principal patterns of reticulation may be seen. These are…
Nodular Lung Disease
Diffuse lung diseases presenting with small nodules (less than 1 cm in diameter) represent a wide variety of entities in many different disease categories. HRCT is generally used to suggest…
Pulmonary Infections
Infection is a common cause of lung disease in both immunocompromised patients and those with a normal immune status. This chapter focuses on a general approach to suspected infection, the…
Increased Lung Attenuation: Ground Glass Opacity and Consolidation
Abnormalities characterized by increased lung opacity can be divided into two categories based upon their attenuation: ground glass opacity (GGO) and consolidation. Each of these findings tends to be nonspecific…
Neoplastic and Lymphoproliferative Diseases
Pulmonary neoplasm and lymphoproliferative disorders may present with diffuse lung abnormalities. The goal of this chapter is to discuss the various patterns of diffuse pulmonary neoplasm and lymphoproliferative disease and…
