Radiologic imaging of malignancy has evolved over the past 20 years. It not only provides better detection with superior anatomic resolution through computed tomography (CT) and magnetic resonance (MR) imaging, but it also provides physiologic information through positron emission tomography (PET). Today's technology incorporates the use of image modality fusion for even better disease localization and characterization. By fusing data from PET and CT studies, radiologic imaging brings together the superior resolution of CT with the low resolution of PET, thereby providing important information on tumor metabolism and replication. Tumor imaging is at the forefront of this technology explosion and is the focus of most cutting-edge research, as well as clinical applications. This chapter reviews current imaging of primary and metastatic malignancies of the thorax.

A Disquistion On The Evils Of Using Tobacco

Among the evils which a vitiated appetite has fastened upon mankind, those that arise from the use of Tobacco hold a prominent place, and call loudly for reform.
