The FDA has issued a public warning notice stating that breast thermography is not an alternative to mammography [8] and has ordered Joseph Mercola to stop making excessive claims for thermography. [9] Thermography is discouraged in North America by the American Cancer Society, radiologists and the FDA for early breast cancer detection.
Its applications include assessment of myocardial ischemia and viability, cardiomyopathies, myocarditis, iron overload, vascular diseases, and congenital heart disease. [5] It is the reference standard for the assessment of cardiac structure and function, [6] and is valuable for diagnosis and surgical planning in complex congenital heart ...
A physician may recommend cardiac imaging to support a diagnosis of a heart condition. Medical specialty professional organizations discourage the use of routine cardiac imaging during pre-operative assessment for patients about to undergo low or mid-risk non-cardiac surgery because the procedure carries risks and is unlikely to result in the change of a patient's management.

Reduced blood flow to the heart associated with coronary ischemia can result in inadequate oxygen supply to the heart muscle. [6] When oxygen supply to the heart is unable to keep up with oxygen demand from the muscle, the result is the characteristic symptoms of coronary ischemia, the most common of which is chest pain. [6]
Water Bottle Heart is a descriptive term used in radiology to describe the appearance of the cardiac silhouette on a chest X-ray when it resembles the shape of a water bottle. This sign is associated with pericardial effusion , a medical condition characterized by the accumulation of fluid in the pericardial cavity surrounding the heart.
Although thermography devices have since been cleared by the Food and Drug Administration (FDA), the agency specifies they should only be used in tandem with another screening or diagnostic test ...

The resulting images show that the volumetrically derived blood pools in the chambers of the heart and timed images may be computationally interpreted to calculate the ejection fraction and injection fraction of the heart. The Massardo method can be used to calculate ventricle volumes. This nuclear medicine scan yields an accurate, inexpensive ...
