Cleft lip (CL) and cleft palate (CP) are common orbitofacial birth defects that vary in severity and effect on anatomical function. They might occur as an isolated event, be associated with a syndrome, or result from genetic and environmental factors. Diagnosis and treatment of individuals begin prenatally and can extend through adulthood.

Child abuse involves grave and disturbing acts of violence that can have lasting physical and emotional consequences for children and their families. The diagnosis of child abuse is emotionally difficult for those involved, and an error in judgment either way can have a detrimental effect on the health and safety of the child. Physicians rely on the skills of the imaging team to produce high-quality images that assist in differentiating inflicted injuries from accidental trauma.

Innovation in breast imaging techniques is leading to better breast cancer detection. Concurrently, breast cancer screening recommendations are changing, and breast density is becoming a more significant factor in breast cancer screening. Digital mammography has become the preferred screening method, with more breast imaging centers including the use of digital breast tomosynthesis (DBT).

Potential biological damage from radiation received during fluoroscopy procedures is of particular concern because of the high volume and variety of procedures performed and the increasing length of radiation exposure. This article focuses on the effects of low-level radiation, gaps in education and skills among personnel performing and assisting with fluoroscopy, the certification and privileging of fluoroscopy personnel, and compliance with radiation protection practices.

Stroke is one of the leading causes of long-term disability and the fourth leading cause of death in the United States, killing more than 137,000 people a year. Time is critical during a stroke because prompt diagnosis and subsequent treatment can prevent the potential loss of brain function. Radiologic technologists who work in computed tomography (CT) must know how to perform CT perfusion and understand stroke diagnosis.

Mammography has long been considered the gold standard for screening breast cancer. Although it reduces the risk of breast cancer mortality by enabling early diagnosis, it does not detect all breast cancers. Numerous breast imaging technologies are emerging as effective adjunctive diagnostic tools when mammography results are negative or inconclusive.

Objectives: The study aims to highlight the potentially serious consequences of inadvertent soft-tissue injection of intrathecal drugs such as clonidine, during refills of implanted drug delivery devices, and to suggest strategies to reduce this complication.

Design: Case report and literature review were used.

Results: We report the case of a 51-year-old female with chronic arm pain who sustained a massive clonidine overdose (18,000 mcg) due to inadvertent soft-tissue injection during a refill of an implanted drug delivery device, resulting in rapid loss of consciousness and significant cardiovascular instability requiring urgent resuscitation, subsequent myocardial infarction, cardiac failure, and other significant complications.

Genetics is playing an increasingly important role in the diagnosis, monitoring and treatment of diseases, and the expansion of genetics into health care has generated the field of genomic medicine. Health care delivery is shifting away from general diagnostic evaluation toward a generation of therapeutics based on a patient's genetic makeup. Meanwhile, the scientific community debates how best to incorporate genetics and genomic medicine into practice.
