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.

Risks and benefits of computed tomography in young adults

The underlying medical conditions facing young adults who undergo computed tomography (CT) exams represent a significantly greater health risk than that of radiation-induced cancer from CT, according to a new study published online in the journal Radiology.

PET with 11C-PIB can positively visualize amyloid deposits in the heart

While amyloid imaging may now be most associated with detecting plaques in the brain, it has the potential to change the way cardiac amyloidosis is diagnosed. According to first-of-its-kind research published in the February issue of The Journal of Nuclear Medicine, positron emission tomography (PET) with 11C-PIB can positively visualize amyloid deposits in the heart.

VMAT use to deliver prostate intensity-modulated radiation therapy reduces treatment time

According to a study in the January issue of the Journal of the American College of Radiology, the use of volume-modulated arc therapy (VMAT) to deliver intensity-modulated radiation therapy (IMRT) to prostate cancer patients results in an overall reduction in treatment time of approximately 14 percent. The study was performed at Winship Cancer Institute of Emory University in Atlanta.

Researchers identify 7 factors to lessen radiation exposure in young, traumatic injury victims

A study of more than 12,000 children from emergency departments throughout the country in the Pediatric Emergency Care Applied Research Network (PECARN) has identified seven factors that can help physicians determine the need for a computed tomography (CT) scan following blunt trauma to the abdomen.

Book reviews psilocybin's potential in alleviating psychological distress in cancer patients

Improvements in the diagnosis and treatment of cancers in recent years have led to a marked increase in patients' physical survival rates. While doctors can treat the physical disease, what is not well understood is how best to address the psychological needs of patients with cancer.

Study expands and deepens biological and genetic links between CVD and schizophrenia

A new study, to be published in the Feb. 7, 2013 issue of the American Journal of Human Genetics, expands and deepens the biological and genetic links between cardiovascular disease and schizophrenia. Cardiovascular disease (CVD) is the leading cause of premature death among schizophrenia patients, who die from heart and blood vessel disorders at a rate double that of persons without the mental disorder.

Pipeline embolization device safe and effective tool for patients with brain aneurysms

A multi-center study supports the effectiveness of the newest technology available for the treatment of difficult, life-threatening brain aneurysms. The technology, the Pipeline embolization device, is a flow diverter that redirects blood flow away from wide-necked or giant aneurysms that cannot be treated in more conventional ways.

HIV-positive patients have higher incidence of non-melanoma skin cancers

HIV-positive patients have a higher incidence of non-melanoma skin cancers, according to a Kaiser Permanente study that appears in the current online issue of the Journal of the National Cancer Institute. Specifically, basal cell and squamous cell carcinomas occur more than twice as often among HIV-positive individuals compared to those who are HIV-negative.
