Computer-aided detection and diagnosis of breast cancer.

The use of computer-aided detection (CAD) with film or digital mammography is now widely regarded as the standard of practice in mammography and has been shown to increase the rate of breast cancer detection. There are inherent limitations in 2D mammography, and new technologies involving 2D and 3D imaging with X-rays, ultrasound, and MRI are in use or under investigation. CAD can aid in the re...

MRI of the ankle and hindfoot.

MRI of the ankle and hindfoot has become a widely used diagnostic test. The major indications for MRI of this region are disorders of tendons and bones. Avascular necrosis is common in the foot, usually seen after talus fractures or spontaneously in the metatarsal heads. Other causes of a marrow edema pattern include occult fractures, arthritic disorders, reactions to altered biomechanics, oste...

The role of endoscopic ultrasound in the evaluation of rectal cancer

Accurate staging of rectal cancer is essential for selecting patients who can undergo sphincter-preserving surgery. It may also identify patients who could benefit from neoadjuvant therapy. Clinical staging is usually accomplished using a combination of physical examination, CT scanning, MRI and endoscopic ultrasound (EUS). Transrectal EUS is increasingly being used for locoregional staging of ...

Neuroimaging and neurodevelopmental outcomes in preterm infants.

Imaging of the preterm infant brain has advanced dramatically beyond the earliest era of transillumination. Computed tomography (CT), a crucial innovation during the early 1970s, allowed noninvasive visualization of intracerebral lesions, particularly hemorrhage. The capability to document brain injury in the preterm infant led to better clarification of links to developmental outcomes. With th...
