Results showed that 3T MRI detected 66/66 malignant lesions; mammography detected 54/66 malignant lesions; and sonography detected 57/66 malignant lesions. “3T MRI depicted a significantly higher number of malignant tumors of the breast than mammography and sonography,” said Haitham Elsamaloty, MD, lead author of the study.

For those not familar, 3T is a higher field strength for MRI machines. Much higher than 3T field strengths are available but only in a research and not a hospital or clinical setting. Many hospitals are now having 3T MRI scanners so if you feel you would benefit you can request and make sure you use one that is 3T. I question whether 3T is better than 1.5T for other types of cancers and diseases.

3T MRI Detects Breast Cancer Not Seen on other Modalities

Both magnetic resonance imaging technologies rely on manipulating the spin of molecules to provide more detailed scans that one day could rapidly do things like analyze how well a drug is working or tell how fast tumors are growing at the molecular level. The technique could  replace current imaging technologies that depend on the use of radioactive substances or heavy metals.”

The research team based their technique on manipulating parahydrogen by transferring its magnetism to more easily detected molecules. This could potentially translated to increase scan sensitivity by 1000 times. This technique creates large imbalances among the populations spin states and makes the molecules into more powerful magnets. This in turn leads to more detailed images.
