Radiology is the medical specialty directing medical imaging technologies to diagnose and sometimes treat diseases. Originally it was the aspect of medical science dealing with the medical use of electromagnetic energy emitted by X-ray machines or other such radiation devices for the purpose of obtaining visual information as part of medical imaging.

Molecular breast imaging is the key to early detection in nearly half of women

Early detection is key to breast cancer survival. But nearly half of all women in the U.S. have dense breast tissue, which can make detecting breast cancer difficult with a mammogram.

Groundbreaking MRI technique reveals microvascular pulsations in the aging brain

Researchers at the Mark and Mary Stevens Neuroimaging and Informatics Institute (Stevens INI) at the Keck School of Medicine of USC have developed a groundbreaking brain imaging technique that reveals how tiny blood vessels in the brain pulse with each heartbeat-changes that may hold clues to aging and diseases such as Alzheimer's.

Molecular breast imaging increases overall invasive cancer detection in women with dense breasts

Screening women with dense breasts with both molecular breast imaging (MBI) and digital breast tomosynthesis (DBT) increased overall invasive cancer detection while modestly increasing the recall rate compared with screening only with DBT, according to a new study published today in Radiology, a journal of the Radiological Society of North America.

Emphysema detected on CT predicts mortality from all causes

Emphysema detected on baseline low-dose chest CT (LDCT) in the lung cancer screening cohort of more than 9,000 asymptomatic adults was associated with death from all causes, chronic obstructive pulmonary disease (COPD), and cardiovascular disease within a 25-year follow-up period in a new study published today in Radiology, a journal of the Radiological Society of North America.
