The radiologist as a palliative care subspecialist: providing symptom relief when cure is not possible.
The purpose of this study was to determine the percentage of patients referred to an interventional radiology (IR) practice who need palliative care and to examine the training required for a diplomate of the American Board of Radiology (ABR) to qualify for the hospice and palliative medicine certifying examination. ⋯ Procedures related to palliative care currently compose the majority of our IR cases. Certification in hospice and palliative medicine can be achieved with a modest investment of time and clinical training.

Comparative StudyIncidence of immediate gadolinium contrast media reactions.
Our objective was to determine the incidence of immediate adverse events for gadolinium-based contrast agents. ⋯ This limited retrospective analysis shows that gadolinium-based contrast agents are very safe, with only rare reports of death, and raises the possibility that nonionic linear gadolinium-based contrast agents and gadopentetate dimeglumine may have fewer severe immediate adverse events compared with gadobenate dimeglumine.

Comparative StudyPediatric CT sedation: comparison of dexmedetomidine and pentobarbital.
Our institution replaced pentobarbital with dexmedetomidine for pediatric CT sedation. The purpose of this study was to compare the efficacy, incidence of adverse events, and cardiovascular and respiratory profiles of these two sedatives. ⋯ Dexmedetomidine is a safe and effective alternative to pentobarbital for pediatric CT, being associated with a much shorter recovery time and less need for adjuvant sedatives.

Birt-Hogg-Dubé syndrome manifests in the thorax as lung cysts. The purpose of this article is to describe the CT characteristics of cysts in patients with Birt-Hogg-Dubé syndrome and to note other thoracic findings. ⋯ Discrete thin-walled cysts in patients with Birt-Hogg-Dubé syndrome are more numerous and larger in the lower lobes and vary in size and shape. Large lung cysts are frequently multiseptated. These features may aid in differentiating Birt-Hogg-Dubé syndrome from other more common cystic lung diseases.

Radiation-related cancer risks in a clinical patient population undergoing cardiac CT.
The purpose of our study was to estimate cancer induction risk and generate risk conversion factors in cardiac CT angiography. ⋯ The average cancer induction risk in sensitive organs from cardiac CT angiography for our patient cohort was 0.13%, with a female to male cancer induction risk ratio of 2.6.
