"Just like high-tech infrared photography, medical imaging can trick physicians into thinking they know more than they really do. Doctors routinely dismiss possible diagnoses because their high-tech tools show a negative result. False-positive results—a scan that indicates there's something wrong when there isn't—can lead them to perform even more unnecessary tests, some of which can be invasive and potentially dangerous, in an effort to confirm the (incorrect) diagnosis. The power of imaging tests to fool doctors can be seen readily in appendicitis." - Shannon Brownlee, Overtreated: Why Too Much Medicine Is Making Us Sicker and Poorer (Get the book.)

"X-ray radiation from medical imaging and CT scans are also believed to increase the risk for cancer. A report issued by the Food & Drug Administration now suggests the risk for cancer from medical x-rays may be as much as 1 in 1,000. There are over 3 billion x-ray images taken annually in the world. Dr. Richard C. Semelka, MD, says patients receiving multiple CT scans today are being exposed to doses of radiation comparable to those given off by the x-ray machines used in the 1930s and 1940s. Cancers do not emanate from x-rays till years later." - Bill Sardi, You Don't Have to be Afraid of Cancer Anymore (Get the book.) "Source: medical imaging Newsletter One out of three mammograms produce abnormal results that require further testing, but subsequent tests reveal no cancer. About 19% of biopsies are needless and cause 16 million false alarms over 10 years. [New England Journal Medicine, April 16, 1998] If a group of women begin breast screening at age 40, by age 50 half of them will have at least one false positive test and undergo needless biopsy. [The Ottawa Citizen, Sept. 4, 2002] Out of 100 positive mammograms, only 20 will actually indicate the presence of cancer. [LA Times Aug." - Bill Sardi, You Don't Have to be Afraid of Cancer Anymore (Get the book.)

"This is a medical imaging technique that uses the same principle as NMR. The word nuclear was removed from the name because of the negative connotations of the term.1-'' Let's go straight to how we can use C-13 NMR data to help find the structure of a molecule. A C-13 NMR spectrum of the same sample we used for our IR example (from Figure 5.11) is shown in Figure 5.13. The horizontal axis is called the chemical shift and is measured in parts per million (ppm). The vertical axis corresponds to peak strength; peaks point up in NMR spectroscopy." - Bryan Hanson, PhD, Understanding Medicinal Plants: Their Chemistry And Therapeutic Action (Get the book.)

"A single computerized scan of the stomach today can give half the dose that was shown to induce cancer in those who survived the atomic bomb blasts in Japan. The ACR advises that "the current annual collective dose estimate from medical exposure in the United States has been calculated as roughly equivalent to the total worldwide collective dose generated by the nuclear catastrophe at Chernobyl."20 Let me translate this." - Devra Davis, The Secret History of the War on Cancer (Get the book.)
