Magnetic Resonence Imaging


In MRI the magnetic nuclei of the patient are aligned in a strong uniform magnetic field, absorb energy from tuned radiofrequency pulses, an emit radiofrequency signals as their excitation decays. This allows for multiplanar demonstration of anatomy with high resolution without the use of x-ray radiation. MRI is most commonly used for investigation of the brain, spine and major joints. In some cases intravenous gadolinium contrast is administered.

Other useful applications include noninvasive vascular assessment (MR angiography), and three dimensional demonstration of structures such as the biliary tree (MRCP) and renal tract, for example.

MRI is also used for conditions in the skull base and neck soft tissues, heart, mediastinum and aorta, abdominal and pelvic organs and for soft tissue mass assessment. Because of the strong magnetic field, patients with pacemakers and certain metallic implants are excluded from having MR.

Breast Magnetic Resonance Imaging (MRI)

It is important to have a breast MRI done at a facility with MRI equipment designed specifically for the imaging of the breasts.

Sandton Radiology now offers state of the art breast imaging at the Medicinic Morningside branch , with a dedicated team of female radiographers , Radiologists and nursing staff, offering a high quality breast facility.
