 Magnetics is big business in medicine, especially in imaging. Most readers will be familiar with the MRI (magnetic resonance imaging) machine, which uses magnetics to create an image of tissue by measuring tissue density. It is a static technology. However, the newer fMRI (functional magnetic resonance imaging) is a dynamic technology that images parts of the body, such as the brain, as they are working. |

 There are some new ways of doing brain imaging that can actually show changes in the brains of some of the people that are exposed to neurotoxic substances. For example, if a child sniffs glue or hair spray or aerosols, you can actually show a characteristic pattern of change in the brain imaging-pattern on the particular individual, which will look different from somebody who has epilepsy or someone who has schizophrenia or depression. They actually produce different brain pictures. |

However, the newer fMRI (functional magnetic resonance imaging) is a dynamic technology that images parts of the body, such as the brain, as they are working. For instance, in the brain, fMRI measures blood flow, volume, and oxygenation and so can see how different parts of the brain become active as the person whose brain is being imaged carries out different tasks. |

 MRI (magnetic resonance imaging) is a structural approach that provides more details than CT (computerized tomography) scanning, which is the most commonly used and cheapest form of structural imaging. However, these details can at times be more confusing than helpful. MRI scans can show smaller strokes, and that is helpful in the differential diagnosis of vascular dementia; but it also shows what we call "unidentified bright objects," which are of unclear significance and could indicate anything from small strokes, to normal aging, to other phenomena that we don't understand. |

 My main area of research has involved imaging the brain of patients who suffer from depression and other mental disorders. Several years ago I was contacted by the families of some young people who had killed themselves while taking a medication for acne called Accutane. They asked if brain imaging would show similar changes in the same area of the brain of all those who were so adversely affected by Accutane. I spoke with the company that made the drug about supporting research, but it wasn't interested. |

| These imaging and blood tests are intended to identify what biological processes may be affecting your memory and other thinking abilities. The CT scan can detect tumors, blood clots, or strokes, while blood tests are designed to detect metabolic disturbances or endocrine deficiencies.
Expensive neuroimaging is the latest craze in the Alzheimer's field. Standard CT and MRI scans are a part of routine practice, although there is some controversy about when to use each. |

 Investigators looked at whether or not functional changes in the heart could be detected by sophisticated nuclear imaging. The researchers, using single photon emission tomography (SPET), were able to document and directly measure a significant therapeutic effect of coenzyme Qio- Their research confirmed previous findings about the clinical effectiveness of coenzyme Qi0 supplementation, as well as the appropriateness of metabolic SPET imaging as a way to measure the clinical impact of coenzyme Qio in hearts. |

 Beyond these physical programs, it's worth discussing imaging, progressive muscular relaxation, and the Relaxation Response, all common methods of reducing stress that are easy and enjoyable. In imaging, you listen to a tape (often available at your local library) and concentrate on putting yourself in the situation portrayed on the tape. Usually, you're asked to picture yourself in a very pleasant environment and then to focus on that environment, freeing your mind of distracting thoughts. |

 The same survey also revealed that a majority of doctors would send their patients to get expensive imaging work done at an imaging facility in which they held a financial interest, but only 24 percent of doctors said they would reveal that conflict of interest to patients.
Result: Yet more incompetent, dishonest doctors continue to scam customers and harm patients. |

| My study of the effects of Accutane on brain function using brain imaging was first presented in November 2004. My theory was that if Accutane affected the brain and caused depression in that way, we should be able to detect it with brain imaging. My colleagues and I did in fact find that Accutane caused a decrease in function in the orbitofrontal cortex. That was identical to what we found in patients who developed depression. This showed that Accutane was affecting brain areas that were knoWn to underlie depression. |

 While brain imaging has its origins with computerized tomography in the 1960s, its most spectacular contributions have occurred in the last fifteen years. Even when CT scans did reveal startling images in the 1970s—as did a landmark 1976 study that showed that the brains of people with schizophrenia had much larger ventricles than did "normals"—the results were received with doubt, as schizophrenia was assumed to be a psychological disease.70 As George H.

 The diagnosis of manganese-related illness in such cases has been made possible by refinements in imaging techniques that allow detection by MRI of subtle signals given off by metal deposits in the brain.102
Clinical observation has also shown that manganese can induce psychiatric illness. Moreover, when this illness occuts, it usually precedes the later development of the Parkinsonian featutes of chronic poisoning. The term manganese mania was coined as the descriptor of this psychiatric phenomenon. |
| Magnetic resonance imaging (MRI), a technology that was not clinically available when toluene-related nervous system toxicity was first reported, has since shown that parts of the brain simply wither away in chronic toluene-laced glue sniffers.

Many brands of glue still contain toluene ot even hexane, but they no longer dominate the market. A stroll through any hardware store will quickly demonstrate that rubber cement has lost shelf space. |

 Additional PET-scan imaging of his experimental patients at five years confirmed that 99 percent were able to halt or reverse disease. There was a direct correlation between adherence to the program after one year and after five years.
Dr. Ornish reported twenty-five new coronary events in his experimental patients at five years, which were 2.5 times fewer events than were identified in his control patients receiving traditional cardiac care. I have personally met some of Dr. Ornish's original patients, who like mine were doing well nineteen years later. |

 Recently, researchers at Harvard Medical School used standard MRI imaging to show visible differences in the brains of those who regularly practice meditation. Over time, areas of the brain that have to do with sensory processing became thicker in the meditators, and these physical changes profoundly changed the day-today modulation of the meditators' heart rates and breathing. |

The researchers had never seen anything like it. To be sure there was no mistake, they brought in other long-term Buddhist practitioners (both monks and laypeople) and compared their brain wave activity in meditation to that of a control group of college students inexperienced in meditation. Those practitioners produced gamma waves that were thirty times as strong as the students'. |

 Certification of mammogram readers and imaging centers
In a woman's lifetime, if she begins breast screening at the age of 50, she could experience as many as three false-positive mammograms. [Journal National Cancer Institute 92: 1657-66, 2000] The false-positive rates (percent of the time cancer is diagnosed when in fact it doesn't exist) among radiologists varies by 1.5 to 24.1 %. |

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. |
| When this fact hit the news wires, breast cancer imaging centers and makers of mammography units circled their wagons in defense of their technology. Upon re-analysis, researchers dispelled the idea that mammograms lead to needless care, but still could not produce a meaningful reduction in mortality rates. [Lancet 359: 909-19, 2002] While there has been a reduction in mortality rates for breast cancer in many countries, there is no clear link this is related to screening. A recent report concluded: "If women choose screening, they should understand their risk of dying may not be reduced. |

 Using the latest magnetic resonance imaging (MRI) technology, researchers from the Medical Research Council Cognition and Brain Sciences Unit in Cambridge showed people pictures of appetizing foods (e.g., chocolate cakes), bland foods (e.g., broccoli), and disgusting foods (e.g., rotten meat), while measuring brain activity in regions of the brain that respond to food cues (such as the amygdala, orbito-frontal, ventral striatal, and midbrain regions). Curiously, the researchers found that some folks are more responsive to tempting food images.

| Brain imaging has shown that social and psychological experiences exert measurable changes in the brain. Specifically, learning and social experience—such as psychotherapy, for what is psychotherapy other than a particularly intensive form of learning?— are capable of producing changes in the brain at the level of neuronal and synaptic connections. There is no longer any doubt that psychotherapy can change the brain at functional and structural levels. |

 Laparoscopic surgery has the advantage of extensive use of microscopic imaging so that surgeons can view lesions in greater detail. In addition, laparoscopy allows for a shorter recuperation time when compared to a laparotomy. During a laparotomy, the surgeon makes a larger incision in the abdomen, allowing for larger endometriomas or adhesions to be excised.
Surgery has produced cure for some individuals, while it has proved to be disappointing to others. Whether laparotomy or laparoscopy, surgical treatment varies as to type of surgery, technique, and surgeon experience. |

| 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. |
