MRI breasts has the highest sensitivity to detect breast cancer when compared with other imaging modalities such as breast ultrasound or mammography. In the screening for breast cancer for high-risk women, sensitivity of MRI range from 83 to 94% while specificity (the confidence that a lesion is cancerous and not a false positive) range from 75.2% to 100%.

Spinal tumor. Spinal tumors are neoplasms located in either the vertebral column or the spinal cord. [1] There are three main types of spinal tumors classified based on their location: extradural and intradural (intradural-intramedullary and intradural-extramedullary). Extradural tumors are located outside the dura mater lining and are most ...
Magnetic resonance imaging ( MRI) is a medical imaging technique used in radiology to form pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to generate images of the organs in the body. MRI does not involve X-rays or the use of ionizing ...
Cancer screening. A person preparing for breast cancer screening by mammography. Purpose. detection of cancer prior to onset of symptoms (via several tests/imaging) The objective of cancer screening is to detect cancer before symptoms appear, involving various methods such as blood tests, urine tests, DNA tests, and medical imaging.
Determining the extent to which a cancer has developed. Cancer staging is the process of determining the extent to which a cancer has grown and spread. A number from I to IV is assigned, with I being an isolated cancer and IV being a cancer that has metastasized and spread from its origin. The stage generally takes into account the size of a ...
Physics of magnetic resonance imaging. Modern 3 tesla clinical MRI scanner. Magnetic resonance imaging (MRI) is a medical imaging technique mostly used in radiology and nuclear medicine in order to investigate the anatomy and physiology of the body, and to detect pathologies including tumors, inflammation, neurological conditions such as stroke ...
Thyroid cancer accounts for less than 1% of cancer cases and deaths in the UK. Around 2,700 people were diagnosed with thyroid cancer in the UK in 2011, and around 370 people died from the disease in 2012. However, in South Korea, thyroid cancer was the 5th most prevalent cancer, which accounted for 7.7% of new cancer cases in 2020.
An atypical teratoid rhabdoid tumor ( AT/RT) is a rare tumor usually diagnosed in childhood. Although usually a brain tumor, AT/RT can occur anywhere in the central nervous system (CNS), including the spinal cord. About 60% will be in the posterior cranial fossa (particularly the cerebellum ). One review estimated 52% in the posterior fossa, 39% are supratentorial primitive neuroectodermal ...
