Summary:

""An excellent primer on medical imaging for all members of the medical profession . . . including non-radiological specialists. It is technically solid and filled with diagrams and clinical images illustrating important points, but it is also easily readable . . . So many outstanding chapters . . . The book uses little mathematics beyond simple algebra [and] presents complex ideas in very understandable terms.""-Melvin E. Clouse, MD, Vice Chairman Emeritus, Department of Radiology, Beth Israel Deaconess Medical Center and Deaconess Professor of Radiology, Harvard Medical School<

Different imaging probes interact with different tissues in different ways and yield different kinds of medical informationTwentieth-century (analog) radiography and fluoroscopy: contrast from differential attenuation of X-rays by tissues; X-ray film of a cracked phalange; Generating the beam at the anode of the X-ray tube; Contrast from differential attenuation of the beam within the body; Exposure of a screen-film image receptor; Image intensifier-based fluoroscopy with a CCD/CMOS electronic optical camera

Twenty-first century (digital) images and digital planar imaging: computer-based images and solid-state image receptorsDigital images; Computed tomography: three-dimensional mapping of X-ray attenuation by tissues; Helical, multi-slice CT; Nuclear medicine, including SPECT and PET: contrast from the differential uptake of a radiopharmaceutical by tissues; Radiopharmaceutical = radionucleus + organ-specific agent; Creating contrast through differential uptake of photon-generating radiopharmaceuticals; SPECT and PET
